LAUPER Christoph - Three Essays in Macroeconomics

This thesis aims to provide a more nuanced understanding of the effects of monetary policy by addressing several aspects that are often overlooked in traditional analysis. It emphasizes the importance of distributional aspects, central bank communication, and the time-varying nature of the underlying economic shocks.

Chapter 1 examines the impact of monetary policy on inflation heterogeneity across households, revealing that contractionary monetary shocks reduce inflation dispersion, with sectors such as energy and fuel playing a significant role. It highlights inflation inequality across income groups and shows that accounting for inflation heterogeneity dampens the impact of monetary policy on expenditure inequality. Chapter 2 focuses on the informational components of monetary policy, and particularly its effects on exchange rates. It distinguishes between Delphic and Odyssean shocks and shows that exchange rates are more responsive to central bank communication than to conventional policy shocks. Chapter 3 examines the time variation in the relative importance of supply and demand shocks over the past 50 years. It introduces a novel measure to quantify these changes using professional forecasts and provides new insights into the repercussions of supply or demand-dominated economies.


TIÈCHE Simon - Three Essays in International Economics and Finance

This dissertation is composed of three essays in international economics and finance, which share a common focus on understanding the micro-foundation of capital flows and the subsequent global economic cycle. The first essay shows US equity mutual funds respond significantly to a measure of expected excess return we predict. However, costly deviations from two benchmark portfolios lead to a weaker and more gradual response of portfolio to changes in expected excess returns. Building upon these findings, the second essay documents country shares of zero in international portfolio choice. Here I show the portfolio impulse response of equity mutual funds to an expected excess return shock is higher and more persistent than estimated when ignoring the zeros.  The third essay shows that following a downturn of the global financial cycle, the US Treasury premium increases and the US real exchange rate appreciates. Moreover, the more the US Treasury premium increases following the downturn of the global financial cycle, the more the US real exchange rate appreciates.

BERLANDA Andrea - Essays in Political Economy

This thesis explores two crucial elements of the promotion of sustainable development: the provision of access to health and the reduction of gender disparities. The first contribution of this work is the exploration of cultural norms that may reduce gender inequalities. In particular, how religious beliefs can lead to more gender equality and a lower gender gap. This thesis investigates then the impact of major health interventions on socioeconomic outcomes in the context of the HIV/AIDS epidemic. Firstly, this research investigates the role of major health interventions on social violence and conflicts. Adverse health shocks can generate social instability and violence when governments are not able to respond to them. This work shows how health policies, such as the introduction and provision of treatment for HIV, have led to a reduction in social unrest. As a final point, this thesis investigates whether health policies can be used as an effective tool to empower women. Women and men are affected unequally by adverse health events, such as the HIV/AIDS pandemic, which can lead to a rise in the gender gap. This work shows how the availability of HIV medications reversed this trend contributing to women empowerment.

KARUNANETHY Kalaivani - Essays in Labor and Education Economics

This thesis consists of three independent essays focusing on the fields of labor economics and the economics of education. These essays study the factors and policies that impact how people make education and labor supply decisions. The findings inform public policy related to family policies and social insurance to ensure more equitable outcomes for vulnerable and disadvantaged groups.

Chapter One finds that income risk has a large and negative ex-ante impact on educational attainments among poor, rural households in India dependent on income from rainfed agriculture. It decreases the number of completed years of schooling, increases the share of people with only primary level education, and decreases the share of people with secondary or higher education. In addition, it increases the likelihood that girls’ education gets interrupted leading them to fall behind, and decreases the amount that households spend on girls’ education.

The second and third chapters relate to family policies, female labor supply, fertility, and gender gaps. The second chapter reveals that introducing a new national mandate providing paid maternity leave only had small and temporary effects on the labor market outcomes of first-time mothers but did raise the share of women having a second child by three percentage points. The third and final chapter shows that the same mandate had an overall negative impact on first-time mothers, decreasing employment and earnings. In addition, it increased slightly the gender gap in total employment but decreased substantially the gap in earnings and wages among those with an older child.

JACOBER Noëmi - Three Essays in Microeconomics: Risk-Taking in Tournaments, Entry in Vertically Differentiated Markets, and Banning Commissions

This thesis is composed of three essays that employ theoretical approaches to model certain market situations in the field of behavioral economics and industrial organization. Chapter 1 studies the role of overconfidence in tournaments where players choose effort provision as well as risk exposure, and shows that, against the common idea, overconfidence can raise effort provision and leads to lower risk-taking. Chapter 2 explores the speed of copycat entry in vertically differentiated markets in which consumers differ in their willingness to pay. This paper identifies welfare-reducing incentives to enter the market which lead to an extended monopoly situation despite costless entry. Chapter 3 analyses the welfare implications of switching from a commission-based to a fee-based remuneration model in markets where consumers rely on expert advice. This study identifies a mechanism through which the number of consumers buying in equilibrium decreases and provokes the question of whether a paradigm shift away from compensation through commissions towards transactional fees is worth the drawbacks.

MAURI Nicola - Setting Taxes on Mobile Bases: Three Essays on Fiscal Federalism

This thesis examines some of the economic consequences of public service and taxation decentralization, both on sub-central governments' policies and on citizens' decisions. More specifically, interest lies in understanding how inter-jurisdictional redistribution policies affect local taxes, to which extent delegation of fiscal authority is effectively implemented, and how jurisdictional fiscal fragmentation affects residential location choices within urban areas. The different chapters overall seek to contribute to the body of research studying how taxes affect the spatial allocation of fiscal resources and to the literature investigating how the mobility of tax bases influences governments' tax-setting behavior. The thesis provides theoretical and empirical insights on questions that help understand how taxes, decentralization and tax-base mobility interact in modern fiscal federations.

ANTUNES Alice - Three Essays in Development Economics: Youth Empowerment, Plagues, and Conflict
In this thesis, I contribute to the study of the economics of youth empowerment, plagues, and conflict. The first chapter uses the results of a randomized controlled trial (RCT) in Colombia to study the effect of adding a youth empowerment program to vocational education for labor market outcomes of marginalized young adults. Three hundred young adults were randomly sorted into three groups: a vocational education and youth empowerment training group, a vocational education-only group, and an untreated control group. Patterns in earnings suggest that the youth empowerment program was initially successful in reducing informal employment compared to the control group; in the medium run, the program seems to affect participants’ overall earnings positively, though earnings come mostly from informal sources. The second chapter uses the previous RCT to explore whether the same youth empowerment program can help vulnerable young adults cope with shocks such as COVID-19. A supplemental survey run during the COVID-19 lockdown indicates that young adults receiving vocational education managed symptoms of depression better during the lockdowns compared to the control group. In the medium run, mental health bounces back to baseline values and there are no differences between groups. The third chapter of this thesis studies the effects of locust outbreaks on conflict in the Sahel in the last twenty years. We find that locusts are associated with less conflict. To understand the underlying mechanisms, we use household agricultural data in Ethiopia in 2014 and find that households having experienced a locust outbreak one month previously have decreased crop incomes and increased non-agricultural wage incomes. The reduction in conflict could arise from three channels, though differentiating between them is not possible in this study: locust outbreaks may be causing a loss in appropriable resources, a loss of resources to compete over, or an increase in social cohesion through informal insurance.
MEICHTRY Pascal - Three Essays on Monetary Policy and Household Heterogeneity

This doctoral thesis examines the effects of both conventional and unconventional monetary policies on the macroeconomy and inequality. Interest rate adjustments, forward guidance, and quantitative easing are common tools used by central banks to control inflation and stabilize economic growth. Policymakers and researchers are therefore increasingly interested in understanding the economic and distributional implications of these policies.

Chapter 1 of the dissertation investigates the interaction of heterogeneity and information rigidities on the part of households and its impact on the transmission of interest rate policy to aggregate demand. Chapter 2 compares the distributional effects of conventional monetary policy and forward guidance, highlighting the importance of fiscal adjustments for addressing inequality. Chapter 3 studies how central bank asset market operations and their interaction with household heterogeneity affect macroeconomic outcomes in the context of a liquidity trap. Overall, the thesis aims to contribute to the ongoing discussion on the role of monetary policy in promoting macroeconomic stability and reducing economic inequality.

MANGIANTE Giacomo - Four Essays in Monetary Economics and Heterogeneity

My thesis focuses on the relationship between monetary policy and heterogeneity. The main objective of the central banks is to stabilize prices. To do so, they have several tools potentially available. These tools can be optimally adopted only by fully understanding the impact they can have on the different agents in the economy like households and firms. Therefore, in my research, I evaluate how the ability of the central bank to achieve its mandate is affected by the heterogeneity in the economy, e.g., demographic trends that change the share of retired people, as well as how the decisions of the monetary authority influence inequality, e.g., consumption or inflation inequality.

ZUCHUAT Jérémy - Three Essays in Labor and Public Economics
This thesis investigates different facets of individuals’ working life, with a special emphasis on the impact of public policies on workers’ decisions and outcomes, to provide new insights on the design of these polices. It is composed of three different chapters seeking to contribute to different bodies of research of labor and public economics. The first chapter analyses the dynamics of job search and the reasons behind the decline in job finding chances over the course of unemployment. The second chapter studies the effects of a specific job search assistance tool, vacancy referrals by caseworkers, on Swiss unemployed job search outcomes. The third chapter investigates how local progressive taxation contributes to the location and commuting decisions of Swiss workers.
FENG Di - Analysis of Multiple-Type Housing Markets

The allocation of scarce resources has attracted significant attention in economic design, with many theoretical and empirical studies focusing on indivisible resources. Most existing literature has investigated unit-demand allocation problems, where each agent consumes only one object. However, in many real-world scenarios, agents may wish to receive more than one object, making the unit-demand assumption inappropriate. Multiple-type housing markets, an extension of Shapley-Scarf housing markets, allow for multi-unit demands and are applicable to various problems such as student enrollments, surgery schedules, and cloud computing. Despite their importance, little research has been done on multiple-type housing markets, and existing results have mainly been negative. In this thesis, we revisit multiple-type housing markets and aim to uncover positive results. We find that not all strict core allocations are implementable and provide a full characterization of the coordinatewise top trading cycles mechanism, which respects individual rationality, achieves unanimity, and maintains strategy-proofness. Additionally, we explore weaker efficiency properties and identify two mechanisms that are compatible with individual rationality and strategy-proofness. Our findings contribute to a better understanding of the multiple-type housing market model, have implications for other areas of research, and can be applied to other fields. The methodology we use to obtain our results is new and could be useful for analyzing higher-dimensional models more efficiently.

LAX MARTINEZ Gema - Three Essays on Political Economy

This thesis contributes to the comprehension of how certain strategies carried out by those in power- such as fiscal policies or the implementation of public spending- usually have side effects, not a priori contemplated in the approval of those policies, and finally affect individuals’ voting decisions or their propensity to get involved in riots. Chapter one analyzes the construction of infrastructure during the military dictatorship in Spain. It shows that places with dams built by the regime exhibit a lower political support for right-wing parties during bad times, i.e. when municipalities are hit by unemployment shocks. The expected positive impact of infrastructure construction on political parties has vanished due to the use of forced labor to build them. The second chapter investigates the effect of fiscal duties on revolts by exploiting a unique policy experiment in 19th century Sicily. After examining different potential mechanisms, we find that it is mostly the threat of taxation that may distort economic investment and ultimately result in greater political turmoil. The last chapter analyzes how different dimensions of democracy might impact the propensity to engage in violent conflict or protests. We start off from a simple game-theoretic model of proportional versus majoritarian representation and then test the key implications of the model, exploiting a unique natural experiment in Cameroon. We find that moving to proportional representation dampens the risk of violence (armed conflict) and promotes instead voice (peaceful protests).

BERTHOLD Brendan - Essays in Macro-Finance & Applied Econometrics

This doctoral thesis aims to better understand the macro-financial effects of different economic risks, with a particular focus on financial volatility and the green transition. Chapter 1 delves into the concept of financial volatility and use creative econometric techniques to distinguish uncertainty from risk aversion shocks. The results highlight the differing nature of the two types of shocks, and can be used to quantify the benefits of policies aimed at stabilizing risk aversion during periods of heightened uncertainty. Chapter 2 and 3 highlight the macro-financial relevance of risks associated with the implementation of climate policies, and provide both theoretical and empirical evidence of the related economic channels. Chapter 4 investigates the opportunity cost of foreign exchange interventions for safe-haven currencies. The results provide a new perspective on the safe-haven properties of the Swiss franc by relying on insights from the literature on intermediary asset pricing.

NÖBAUER Bernhard - Three Essays in Urban and Development Economics Using Spatial Micro-Data

In this thesis, I use recent advances in the availability of spatial data to revisit longstanding questions in empirical microeconomics. My main focus is housing costs, on which most households spend more than on any other expenditure item. I estimate differences in housing costs with respect to a property’s distance to the city center and document different regularities. Moreover, I estimate how much more expensive housing is in larger cities compared to smaller cities. I tackle these questions using novel data on Airbnb rental prices, which allows me to base my research on 734 cities worldwide, a substantially larger sample than what the literature has worked with so far. In a separate analysis, I also use new geographic data, amongst others on mining licenses, but ask a different question: Do exports of natural resources foster or reduce violent conflicts? I provide evidence that natural resource exports can increase local conflict, using the example of Myanmar and its trade in mining goods with neighboring China.

BOLLIGER Elio - Three Essays in Macroeconomics

This doctoral thesis aims to deepen the understanding of financial and informational frictions in macroeconomics, with a particular focus on the evaluation of policies introduced after the financial crisis and expectation formation. Chapter 1 analyses the effects of macroprudential policies on homeownership. It provides novel evidence on the tightening of borrowing constraints after the introduction of this policy and its potential distributional consequences. Chapter 2 tackles the question of informational asymmetries between local and foreign forecasters. Newly developed tests based on a theoretical expectation formation model show that foreign forecasters are less precise than local forecasters when forecasting macroeconomic fundamentals. These results provide a basis for disciplining international finance and trade models with heterogeneous information. Chapter 3 investigates the link of news media and inflation expectations. Based on newspaper articles, it develops a count measure of inflation articles and an innovative inflation sentiment measure using a state-of-the-art natural language processing model. The empirical framework exploits the language barrier in Switzerland and its results provide new insights on the effects of news on households’ inflation expectations.

PHILLOT Maxime - Essays in Macro-Finance and International Economics
In this thesis, the complexities of the demand for and supply of global safe assets are investigated, with a specific emphasis placed on the role that US Treasuries play in the global financial system. It focuses primarily on answering the following three fundamental questions: What kind of effects do sudden shifts in the supply of US Treasuries have on financial markets around the world? What kind of an impact does this supply have on exchange rates, and how does it affect the attractiveness of US Treasuries in comparison to those of other countries? How do shocks in the asset market spread from one country to another, especially when conventional monetary tools are limited? This thesis sheds light on the impact that supply shocks have on interest rates, stock prices, and exchange rates through the introduction of a new method for identifying US Treasury supply shocks. According to the findings of this thesis, fluctuations in the supply of US Treasuries have a significant impact on the global financial markets and the dynamics of exchange rates, whereas shocks in the asset market can, under certain conditions, lead to significant international spillover effects. This thesis highlights the pivotal role that US Treasuries and the dynamics of global safe asset markets play in shaping the financial stability and economic interactions of the global economy.
FRIEDL Aleksandra - Three Essays on Macroeconomics of Climate Change

Macroeconomics of climate change seeks to provide economic insights into how we can address the challenges posed by climate change while promoting sustainable economic growth and equity. It involves modeling the complex interactions between the environment, the economy, and public policies to inform decision-making at the global, national, and local levels. Macroeconomic models of climate change are usually difficult to solve. To overcome this general problem all three chapters of the thesis, while addressing different issues, rely on the computational approach that is based on deep neural net algorithms for economy-climate models.

The first chapter proposes a transparent calibration and evaluation strategy for a climate emulator, a necessary ingredient of any economy-climate model. We demonstrate the importance of the climate emulator for economic analysis and highlight the consequences of its miscalibration. In the second chapter, we address the problem of parametric uncertainty in the climate-economy models. We investigate the impact of the uncertainty around the model parameters on the model outcomes, such as the social cost of carbon. In the third chapter, I explore the role of technological spillovers in developing countries in achieving global decarbonization. The results of the study emphasize the importance of considering both spillovers and carbon taxation when designing effective strategies to achieve environmental goals.


COLELLA Fabrizio - Three Essays in Labor Economics

The three chapters of this thesis contribute to the understanding of how economic shocks and discriminatory behaviors of recruiters and stakeholders impact the allocation of workers in different jobs as well as their performance at work. Chapter one shows that shocks on international prices impact foreign investments and delocalization decisions of firms, and consequently their demand for skills. Chapter two studies how the stereotypical behavior of recruiters affects hiring and how forbidding discriminatory signals can reduce workplace gender segregation without deteriorating the job match efficiency. Chapter three provides evidence of the negative effect of racist harassment by supporters on the performance of non-white athletes.

BASIHOS Seda - Three Essays in Macroeconomics

This thesis explores the role of the rapid obsolescence of widely used computing technology on economic growth, income distribution, and interplay between economic and political competition. The first chapter of the thesis shows, taking U.S. data as a baseline, that rapid technological obsolescence could lead to the rise of giant firms limiting economic growth and competition, the deterioration of income distribution in favor of owners of these firms, and thus a decrease in payments to workers and small entrepreneurs. The second chapter empirically exposes economic power concentrated in the corporate sector by measuring the market power of large firms in the product markets of different countries. Finally, the third chapter examines whether the concentration of market power among this limited group of large firms has led to a concentration of political power that ultimately undermines democracy. This study reveals that a significant portion of the global democratic decline is directly related to large businesses increasingly becoming more influential in the political and economic arena.

AMO-AGYEI Silas - Essays on Subjective Well-Being, Health and Consumption

The chapters of my thesis provide coherent studies on distinct dimensions of individual subjective well-being (SWB) and how they relate to important economic outcomes, such as consumption and health. As a portrayal of human well-being, SWB complements standard aggregate well-being measures, such as GDP, and reflects a wider range of experiences, including those unrelated to market exchange. Owing to recent state-of-theart surveying techniques, these distinct SWB dimensions can be reliably and quantitatively measured.
Using SWB as a proxy for utility, chapter one provides evidence for health-state dependence of the utility function and shows that the marginal utility of consumption increases as health deteriorates, highlighting the capacity of consumption to provide a buffer against the negative impact of health shocks on well-being.
Chapter two studies the association of pain with SWB and shows both evaluative and experienced (emotional) well-being dimensions to be markedly lower for people living with pain than they are for those without pain. Further, pain-related differences in time use between people with pain and those without pain are shown as providing only a small compensating effect. Finally, chapter three documents the direct relationship between evaluative and experienced (emotional) well-being dimensions and highlights the importance of the multidimensional nature of SWB.

PALLARA Kevin - Fiscal Sustainability, Sovereign Credit Risk and Fiscal Policy

Since the Great Recession and, then, with the euro-area sovereign debt crisis and the COVID pandemic, fiscal sustainability has started to be a concern not only for emerging economies but also for advanced ones. Given that rising default risk might have serious economic implications, the study of sovereign credit risk has grown in relevance. At the same time, the ability of the government budget to be resilient to crises has become crucial. Thus, the measurement of the space of maneuver available to governments for the implementation of discretionary fiscal policy — dubbed as fiscal space — has increasingly drawn attention. The first two chapters of this thesis propose a new methodology to assess sovereign debt sustainability and measure credit risk. These studies provide estimates of the maximum outstanding sovereign debt that a country can credibly sustain — the fiscal limit — and develop flexible pricing frameworks for different types of sovereign bonds. The latter include debt instruments issued and guaranteed jointly by a group of countries. Furthermore, the third chapter of this thesis focuses on the study of how the evolution of fiscal sustainability — captured through the concept of fiscal space — affects expansionary fiscal policy. In the last chapter, given the current constrainedness of government budgets in many advanced economies, I explore how the effectiveness of fiscal consolidations hinges on the initial state of the economy.

LEHMANN Tobias - Essays in Labor Economics

The labor market and the dating market, while at first sight very different, have a fundamental commonality: In both markets we pair up with someone (employer or partner), and who this is has far-reaching implications. This thesis empirically studies how we search for matching partners in the labor and the dating market, what problems occur in this process, and how this affects our outcomes. It shows that – like a highway loaded with more cars than it can accommodate – matching markets can suffer from a congestion problem if everyone wants to match with the same partner (or employer). In the labor market context, the thesis studies the importance of non-wage characteristics of jobs, such as a meaningful work content, or a good leadership culture. It shows that non-wage job values are at least as important as wage in driving our decision where to work, and that inequality between workers is substantially greater if we take them into account.

LAFERRIÈRE Vincent - Winner-Take-All Markets, Multigame Contact and Cooperation: Three Essays in Experimental Economics

In Chapter 1, we explain people’s tendency to enter excessively in winner-take-all markets. In such markets, large payoffs are achievable but they are skewed towards a handful of firms or individuals. We test three common explanations for excess entry, none of which is supported. We offer and test empirically a novel explanation for excess entry (Cumulative Prospect Theory). Excess entry into highly competitive markets is not caused by a genuine preference for competing but is instead driven by probability weighting.
Then, we investigate situations where players repeatedly interact across multiple games, i.e., multigame contact. Multigame contact offers great theoretical implications and relates to many real-life situations.
In Chapter 2, subjects play a pair of indefinitely repeated prisoner’s dilemma games either with the same partner, or with two different ones. Surprisingly, multigame contact does not increase cooperation rates. Yet, multigame contact affects behavior and outcomes, acting like a double-edged sword: subjects link decisions across games and outcomes of full cooperation or full defection in both games become more likely.
In Chapter 3, subjects play two indefinitely repeated games: a prisoner’s dilemma and a stag hunt game, either with or without multigame contact. Again, multigame contact does not improve cooperation. In one treatment, multigame contact even leads to less efficient outcomes. Non-credible threats can explain why multigame contact does not help, or even harms cooperation, in our experiment.


MUTLU Rasim - Three Essays on International Markets and Welfare in Emerging Economies

Emerging market economies have gone through several financial crisis after removing barriers to international capital flows. In my thesis, I analyze the welfare implications of various policies implemented by policymakers to alleviate the severity of those crises.

In Chapter 1, I find that welfare gains from financial liberalization decrease when the standard small open economy model is augmented with adjustments costs to capital. In Chapter 2, I analyze the welfare effects of macroprudential policies of implementing a tax on household’s and/or bank’s dollar holdings in a dollarized economy. In the final Chapter, I extend the analysis to study the interaction between macroprudential and monetary policies.

KIENY Clémence - Essays on Gender and Subjective Well-being among Older Adults from the Developing World

This thesis consists of three essays focusing on the subjective well-being (SWB) of older adults in developing countries, with a specific attention to gender inequalities. It exploits data from the World Health Organization’s Study on Global AGEing and Adult Health (SAGE) (2007-2010). Chapter 1 investigates potential gender differences in two dimensions – evaluative and emotional – of SWB among older adults in five low- and middle-income countries. Results show that older women tend to be disadvantaged in terms of both evaluative and emotional well-being, and that this imbalance is mostly driven by their less favorable life circumstances, such as lower socio-economic status and poorer health. Chapter 2 deepens the understanding of the relationship between gender and SWB by focusing specifically on experienced well-being. Results show that the lower experienced well-being reported by women is mostly due to worse affective experiences across all activities, which in turn appears to be linked to the less favorable circumstances under which older women perform these activities. Chapter 3 analyzes the causal impact of work cessation at retirement age - one of the major transitions facing older adults - on SWB in Russia.  Findings demonstrate that emotional well-being improves in the overall study population – especially for men – while evaluative well-being is mostly unaffected by work cessation for both genders. This research contributes to improving the understanding of the drivers of older persons’ SWB. As such, it may provide relevant insights to policymakers considering options to improve the welfare of older adults and to reduce gender-based inequalities in this population.


MARXEN Annabelle - Anticompetitive behavior in the pharmaceutical industry: Three essays in antitrust economics

This thesis studies the impact of entry agreements in the pharmaceutical industry on competition in the market for generic drugs. Entry agreements between an originator drug producer and one or more potential generic entrants modify the expected entry date of generics and result in anticipated or delayed generic entry. They have become increasingly common and are of concern to competition agencies. In a pay for delay deal for example, an originator and a generic producer settle an ongoing patent litigation by agreeing on a delayed entry of the generic in return of some financial compensation. This deprives consumers of a timely availability of generics and therefore of lower drug prices.


This thesis focuses on a less known but as common type of entry agreement: early entry agreements. Instead of delaying generic entry, these agreements anticipate generic entry. We show that contrary to common belief, the early availability of a generic through an entry agreement is not always procompetitive and can raise antitrust concerns.


In the first chapter of the thesis, we generate a theoretical model designed to study the incentives of firms to enter such an agreement. We find that the originator company may use early entry as a means to circumvent the uncertainty of generic entry at patent expiry. By anticipating some generic entry, the originator firm can eliminate this uncertainty and deter more entry.


The second chapter looks for empirical evidence in support of this theory. We use drug and regulatory data from 11 European countries to study the impact of entry agreements on the level of competition in the generic drug market. Our results suggest that early entry is associated with more generic entry, though we are not able to fully isolate the effect of entry agreements.


The third and last chapter assesses the existing case law concerning entry agreements. The two previous chapters show how entry agreements may be used by the originator in an attempt to deter generic entry and are not solely motivated by a temporary shift in the timeline of generic entry. I therefore advocate for a more comprehensive assessment of entry agreements by competition authorities and courts and the use of the notion of abuse of dominance.


ASPRILLA Alan Guillermo - Three Essays on Trade and Development Economics

This thesis studies three topics on the fields of trade and development economics.

The first chapter analyzes land markets amid civil conflicts. The empirical results show two economic consequences of violence on land markets during Colombia’s conflict. On the one hand, violence reduces the possibility for owners of selling their land since potential buyers’ valuation of land is more affected by violence than owners’ valuation, lowering the volume of land sales. On the other hand, this need not be true if illegal groups have interests in obtaining land titles. I find a positive effect of paramilitary violence on the volume of land sales in regions suited for palm oil production. Consistent with anecdotal evidence, this suggests a systematic use of violence to obtain rural land for further palm oil production, or violent land grab.

The second chapter identifies the effect of international trade in agricultural commodities on the production of cocaine in Colombia. We find evidence suggesting an increase in coffee prices deterring coca cultivation, especially in the proximity of seaports. This suggests a two-fold effect of international trade on the production of crop-based illegal drugs. While an increase in coffee prices encourages the farmers’ transition from illegal to legal crops, this transition is relatively easier if farmers have more access to international markets. Accordingly, we suggest that public policies aiming to ease market access need to be considered in the fight against the production of illegal drugs.

Lastly, the third chapter identifies the effect of trade policy on market power. Using customs information for 12 developing countries, this chapter identifies market power by observing how exporting firms price discriminate across markets in reaction to variations in exchange rates. The results show that while tariffs reduce market power, non-tariff measures alter market structure and reinforce the market power of non-exiting firms. Therefore, non-tariff measures need to be considered both as a trade policy issues and a competition issue, and not mere surrogates of tariffs.

EBERLE Ulrich Jakob - Three Essays in Political Economics

The ambition of this thesis is to quantitatively assess research questions of high policy-relevance relating to conflict. The results presented in all three chapters stem from analyses making use of cutting-edge econometric and spatial methods which - in conjunction - offer a powerful tool set for causal inference.
The first chapter investigates the impact of newly-constructed dams on local conflict around the world. Large-scale infrastructure projects are a frequent source of local protest, which can escalate into violent combats. The analysis reveals that once new dams are built, they disrupt the local economy and increase the likelihood of conflict in the regions surrounding dams. Long-standing antistate grievances and low political competition appear to be closely related to the causes of conflict.
The second chapter, joint with Dominic Rohner and Mathias Thoenig studies conflict between settlers and nomads in Africa. The paper finds that in years of drought, resource scarcity forces nomadic herders to migrate towards the fringes of deserts where they compete with settled farmers over fertile land, resulting in violent conflict. Institutional features such as land dispute resolution mechanisms and secure property rights appear to be effective towards preventing these issues.
The thematic sphere of the third chapter of my thesis focuses on the link between ethnic diversity, social tensions and urbanization. This work is joint with Vernon Henderson, Dominic Rohner and Kurt Schmidheiny. The global analysis at the province-level finds that increased ethno-linguistic fractionalization and polarization are associated with lower urbanization and an increased role for secondary cities relative to the primate city of a province. Policy makers should spend special attention on intermediately democratised countries, as those nations appear to be most prone to experience the adverse effects of ethnic diversity on urbanisation.

LIU Fang - Three Essays on International Macroeconomics

My dissertation consists of three self-contained essays in macroeconomics. The first essay extends the semi-open model to a 2-country model, which generates an endogenous global interest rate corresponding to China's role in the world and makes it possible to test the optimal exchange rate policy and spillover effects. The results could guide the cooperation policy in an international view. The second essay explores the liquidity channel of government bonds between the core and periphery countries in the euro-zone crises through a New Keynesian DSGE 2-country model with liquidity frictions. We find that an external negative liquidity shock can explain some part of the recession and the exchange rate performance. We also test the effect of the fiscal policy, currency policy, and unconventional monetary policy. The third essay is about related party transfer (RPT) in China. We show that RPT is generated from the stimulus and increases with the widening cost difference between State-owned entrepreneurs (SOEs) and Entrepreneur-firms (EFs). Finally, this paper provides a growth model with heterogeneous firms to explain the transition channel between the stimulus package and shadow banking surging.

MANAI Maha - Essays on Decision under Risk, Education and Unemployment

This thesis is a collection of three distinct essays in the fields of behavioral economics and labor economics.

The first essay aims to further our understanding and improve our predictions of decision under risk. Through a joint test of two prominent theories in decision under risk, the essay shows that both theories play a role at describing aggregate choices and uncovers substantial heterogeneity by classifying the subjects into types according to which theory describes best their behavior under risk.

The second essay is set in a context of a rigid labor market with high graduate unemployment. Using the quasi-experimental variation in education created by a centralized allocation mechanism of high school graduates into university programs, I find evidence that selective track graduates struggle to find their first jobs suggesting that the labor market is unable to quickly absorb even the most able university graduates.

The third essay studies the effect of extended unemployment benefits duration on individual health during the Great Recession. I find that the individuals of who stayed unemployed the longest have a negative health response to the introduction and expiry of a program that extends unemployment benefits duration. Because they have been unemployed for more than a year, they might been unaware of their potential eligibility and therefore the program introduction was a letdown. The expiry of the program affected them directly by cutting their income source.


GALLEA Quentin - Globalization: Damages and Benefits

This doctoral thesis is focused to shed some light on mechanisms affecting our world where globalization might benefit or damage us. My work aims to enrich research but also contribute to the world outside academia. To do so, I focus on the topic with current policy implications. In the first three chapters, I studied conflict at different levels: internal conflicts, interstate conflicts, and local conflicts.

First, I showed for the first time the causal effect of weapons transfers on the internal violence in the destination country. The transfers increase conflicts, deaths, the number of refugees and the civilians are the first victims. This work reinforces the legitimacy of arms control.

Second, we show how countries fight to control central positions in the natural gas pipeline network to extract more rents. This work allows predicting interstate dispute risk based on future pipeline projects or price changes.

Third, we study the impact of closeness to strategic positions on water routes on local conflict. Then we show how globalization mitigate the effect by incentivizing other countries to protect those areas valuable for trade.

Fourth, we studied the effect of lockdowns on the spread of the COVID-19. We found that within-country measures were efficient (rather than blocking the borders) and most importantly only in developed countries. Moreover, we discovered, the population, anticipating the lockdown, increase the contact in the days before (e.g: going to the pharmacy or grocery shopping), which contribute to the spread of the virus. Hence, we recommend to focus on within-country lockdowns and to implement quickly those measures to reduce the anticipation effect.



COLZANI Paola - Overconfidence, Dishonesty and Economic Behavior

This thesis consists of three studies on economic behavior. The first two studies analyze the impact overconfidence on market outcomes and effort provision whereas the last one focuses on the impact of dishonesty on individual decision making.

The first chapter uses a laboratory experiment to study the causal impact of self-confidence on bargaining with joint production. Self-confidence is exogenously manipulated by the means of an easy or a hard task. Relative performance in such task generates the joint surplus. The results of this chapter show that, when the joint surplus is low, overconfidence leads to bargaining failures, whereas most people settle on an equal split when the joint surplus is high.

The second chapter analyses theoretically the impact of overconfidence on effort provision in an asymmetric tournament with heterogeneous agents. When overconfidence is small, the effort provision of an overconfident agent increases, whereas the effort provision of an unbiased agent decreases; when overconfidence is large, the effort provision of all agents decreases, compared to a symmetric equilibrium with unbiased workers. For a given prize spread, a firm is better off when overconfidence is small since profits are higher on average.

The third chapter studies experimentally the determinants of lying behavior in absence of strategic interactions. In this context, it is shown that observing lying increases lying. The chapter also suggests that those who expect others to be truthful but observe lying, lie more than those who expect others to be truthful and observe truth telling. Yet, it is not the case that those who expect others to lie but observe truth telling lie less than those who expect lying and observe lying.




PROTOPAPAS Panagiotis - Three essays in choice and social choice theory

This thesis is composed of three essays, one in Choice Theory (Chapter 1) and two in Social Choice Theory (Chapters 2 and 3). All chapters consider situations where an issue has arisen with a number of alternative ways to deal with it, and some individual (henceforth, some choice correspondence) needs to choose one, or more, of these alternatives in order to deal with this situation.

In Chapter 1, we are interested in choice correspondences that satisfy some of the following properties: two versions of the independence of irrelevant alternatives (IIA and WIIA), as well as the weak axiom of revealed preference (WARP). Loosely speaking, we show that combinations of these properties can partially or completely determine the choice correspondences satisfying said properties.

In Chapters 2 and 3 choice made by the choice correspondence must be according to the preferences of a group of agents. Specifically, we are interested in choice correspondences satisfying some of the following properties.

  • In Chapter 2: Pareto efficiency, population-monotonicity, and replacement domination.
  • In Chapter 3: Pareto efficiency, strategy-proofness, and anonymity.

Loosely speaking, we show that combinations of these properties characterize target set correspondences (Chapter 2) and generalized median correspondences (Chapter 3).


MESQUIDA Yannis - Three essays in household finance

This thesis consists of three research papers, with household finance as common topic. The first paper studies a lifetime combination of financial, work and health-related decisions made by households. The results, obtained from a dynamic life cycle model of allocations and welfare, show that households' lifetime decisions are challenging to match, even after accounting for the complex interactions between them. Whereas financial savings and pension claims are both well matched, the model overestimates health levels, and consequently life expectancy. Moreover, health is maintained through more spending, and less leisure than currently observed. As a consequence, observed post-retirement income is higher than expected, and explains the divergence in consumption after 65. The second part analyzes the homeowners' life cycle responses to financial, health and real estate shocks. After successfully matching the US households life cycle data using a unique structural life cycle model, the results show that asset rebalancing and time allocation decisions are shock-dependent. Unsurprisingly, shocks decrease the net worth and postpone the full retirement age, but in different magnitudes. Notice that when the shock is a real estate market collapse, the life cycle impact is bigger. Finally, the third research paper examines the impacts of conventional (i.e. man-made law) and Islamic (i.e. Sharia rules) financial literacies on the Pakistani households participation in the formal and informal financial sectors. Based on a statistical model, the results highlight that the conventional financial literacy positively and strongly affects the use of formal financial services, while the Islamic financial literacy has a weaker positive impact. Therefore, financial literacy programs could be a way to reduce financial exclusion.


KAEMPFEN Fabrice - Four essays in applied microeconomics

Along the life-cycle, individuals go through a series of important events and turning-points that determine their health characteristics and trajectories, and shape their economic and social well-being. This thesis is about applying economic analysis and tools to understand how some of these turning-points affect one’s health and health behaviors. The three important events that I consider in my thesis are birth, schooling and retirement.

I show in the first chapter of my thesis that children born in Malawi in a year in which their mother experienced a negative economic shock had poorer subjective and objective health outcomes later in life. The second chapter looks at the effects of education on technology use and adoption among older adults in Europe.  I show that persons who acquired more education due to a compulsory schooling reform are more likely to use the Internet and to have better computer skills later in life. The third paper of my thesis uses social security eligibility ages as instruments for retirement in econometric models for physical activity and longitudinal data from the USA. I find that retirement causes older persons to engage in more physical activity, especially among highly educated and wealthy individuals. Finally, the last chapter of my thesis highlights potential reporting heterogeneity in subjective survey measures based on Visual Analogue Scale (VAS) and cautions regarding the use of subjective measures in empirical studies for drawing conclusions on how health, health behaviors and well-being change over the life-cycle.

Along the life-cycle, individuals experience a series of major events that shape their health and ability to engage in economic and social activities. Understanding the effects of these events on individual’s life requires objective measures that are comparable across individuals. My thesis shows that health and health behaviors can be influenced by non-health-related causes occurring throughout life, such as economic shocks at birth, education and retirement. My thesis therefore identifies some of the events that causally determine health and contributes to the current understanding on how health evolves along the life-cycle.

DAUTOVIC Ernest - Three essays in impact evaluation of economic policies

The PhD dissertation consists of three separate chapters. Each chapter is a self-contained work and can be read in isolation. The common themes across the three chapters are techniques and methods for a rigorous and causal assessment of economic policies.

The first chapter evaluates the impact of the Chinese minimum wage policy on consumption of low wage household. Using a representative household panel, we find that poorer households fully consume their additional income. This large propensity to consume is driven by households with at least one child, while childless poor households save two thirds of a minimum wage hike. The expenditure increase is concentrated in health care and education with potentially long-lasting benefits to household welfare.

The second chapter is an evaluation of an investment readiness program for start-ups in the Western Balkans. Investment readiness programs attempt to help firms to become ready to attract and accept outside equity funding through a combination of training, mentoring, master classes, and networking. The investment readiness program resulted in an increase in the investment readiness score. Treated firms attain significantly more media attention, and are more likely to have made a deal with an outside investor, although this increase is not statistically significant.

The third chapter is an impact evaluation of bank capital regulation on bank capital, risk taking behaviour, and solvency. An increase in regulatory capital requirements leads to a capital increase but this comes at a cost. The paper documents the existence of portfolio substitution effects toward riskier assets. The risk taking behaviour is predominantly driven by large and less profitable banks.

VALLE LARA Victoria - Three essays in experimental economics

The thesis consists of three papers that explore the role of incentives and behaviour in different environments. All three papers apply experimental methods to understand the effect of an incentive on a specific behavior.

The first paper explores the role of conflicts in organisations. Intuitively, conflicts are associated with negative emotions, however, the economic literature shows that conflicts can enhance cooperation in settings with symmetric and complete information. In this paper we explore the role of conflicts in the presence of subjectivity. Our findings suggest that even conflicts that appear to be wasteful may be efficiency-enhancing if they occur in a coordinated manner.

The second paper studies the role of incentives in rating systems. Empirical research shows that rating systems tend to have a positive bias. In particular, the systems present an under provision of ratings and, specifically, of negative ratings. In the paper we propose alternative tools to increase the provision of ratings and we make use of experiments to test the efficiency of each tool. The results show that all the incentivised rating systems improve efficiency to some extent compared to the baseline, where no incentives are in place. However, each system suffers from certain weaknesses. Our results suggest that designing an unbiased rating system is not straightforward. The optimal rating system should focus on increasing the incentives to consume without prior information and to provide truthful ratings, whilst keeping implementation simple.

The third paper focuses on the role of charisma on trust. We make use of the charismatic leadership tactics developed in the management literature to test their effect on the trust decision of other players. These charismatic tactics consist of verbal and nonverbal tactics such as the use of metaphors, stories, gestures and tone patterns. Furthermore, we develop a theory that predicts that charisma enhances trust due to the presence of guilt aversion. However, our results are not in line with this prediction. These null results do not indicate that charisma has no effect on cooperation in general. However, they illustrate that it is not trivial to capture the impact of charisma in an experimental setting.


CORDONIER Rachel - Essays in International Macroeconomics

Understanding the drivers of cross-country capital movements is crucial from a policy perspective. Sharp fluctuations of capital may raise concerns on the country’s financial stability. My thesis’ first two chapters study the factors potentially driving capital flows. In particular, the first chapter focuses on the consumer confidence index. This index includes a component of households’ expectations about future economic prospects. A priori, these expectations may reflect true information about the country’s future productivity. They may also represent surges of optimism or pessimism. My findings for 33 countries show that these expectations are significant drivers of capital flows. The aim of the second chapter is to formally determine whether expectations reflecting true information about future productivity, labelled “news”, or expectations mirroring “sentiments” are more important in driving capital flows. The use of a more structured model allows to disentangle these two effects. The findings show that news and to an ever greater extent, sentiment, are able to explain a significant portion of capital flows. Moreover, sentiments are not mere reflections of worldwide factors, but rather, are capturing some country-specific information. The last chapter looks at the consequences of large capital inflows, focusing on emerging economies. The analysis shows that, because of the low interest rates resulting from the U.S. monetary policy, investors have started to invest in these countries, seeking for higher yields. Local companies have thus started to issue more bonds in foreign currency, raising their exposure to exchange rate variations. This risk appears to not be particularly concentrated among certain types of companies and can be limited using capital controls measures.

COTTIER Lionel - From Policy Design to Impact Evaluation, Three Essays in Microeconomics

The first chapter studies how lobbying can influence government decisions on regulatory issues. Firms may find themselves opposed to organized consumer groups in battles for influence over the design of new policies regulating their industry. Understanding the incentives of the different actors involved and their influence over the policy outcomes is therefore important. We show that competition in the production of information enables the government to extract an informational rent from the business lobby. Our results suggest that lobbying battles that look very unequal at first sight may not always yield outcomes in favor of bigger player.


The second chapter evaluates the effects of an intensive job search assistance pilot program offered to long-term job seekers in Geneva, Switzerland. We find that the program improved job re-entry in the short-run, but its participants reached less stable positions, which significantly increased the probability of job loss after two years and canceled out the initial positive effects. These findings highlight the need to consider long-term horizons when evaluating such policies, as some mechanisms may take more time to materialize. Failure to do so may result in overly optimistic results.


The third chapter studies how culture affects male labor supply near retirement before and after reforms that introduced early claiming age of pension benefits. These policy changes significantly reduced the incentives to work for individuals approaching the full retirement age. I find that cultural preferences affect LFP but not when the incentives to work are strong. Results suggest that culture and economic incentives do not simply add up. Incentives dominate, while culture creates heterogeneity in reaction to policies as soon as individuals are given room to adjust their behavior.

STAUBLI David - Two essays on how beliefs and rewards affect risk taking and one essay on corporate income taxation

The first part of this thesis uses laboratory experiments to investigate how beliefs about skill, risk attitude, and the perception of probabilities affect decisions under risk and uncertainty. This is important for many real-life decisions such as choosing a career path where the available options have rewards that are more or less risky and dependent on skill (e.g., working as a lawyer versus working in the public sector). Further, the thesis investigates in more detail how individuals choose between entering a market where rewards are uncertain and a certain outside option. The findings can be summarized as follows: First, low (high) skill individuals are overconfident (underconfident) and therefore overestimate (underestimate) the value of gambles where probabilities depend on skill. Second, overestimation of small success probabilities leads to excess entry into winner-take-all markets, i.e., into markets where rewards are concentrated on very few competitors.

The second part of the thesis investigates the tax sensitivity of firms using Swiss data. The research question is motivated by a general downward trend in corporate tax rates and increasing provision of privileged tax treatments for specific activities in developed countries. Action plans of the EU and the OECD to combat “harmful” tax competition are now forcing countries and jurisdictions to adjust their corporate tax laws. The following empirical findings of this thesis offer guidance for sound corporate tax policy making. First, corporate income reacts significantly to changes in corporate tax rates. However, the reaction is not so strong that a decrease in corporate tax rates would lead to an increase in corporate tax revenue. Second, a significant part of the tax sensitivity is due to mobility of corporate income across jurisdictions. The role of mobility is important, for instance, to gauge the extent to which tax competition is desirable.


PERAZZI Elena - Essays on monetary policy, sovereign debt and banking

The first two chapters of this thesis are related to the debt crisis that hit the Euro area in 2009-2012.
The first chapter examines the effects on financial stability of programs such as the European Financial Stability Facility (EFSF) and the European Stability Mechanism (ESM). I show that such programs generate financial contagion in sovereign debt markets and that, by inducing countries to borrow more, they can increase the frequency of debt crises and defaults.

In the second chapter we ask whether a country similar to one in the Euro periphery could have escaped the debt crisis if it was able to conduct its own monetary policy. We find that an independent monetary policy could in theory avoid the crisis, but doing so involves in general many years of sustained inflation, the cost of which might exceed the cost of a default.

The third and fourth chapters are related to reforms of the banking sector that were proposed after the financial crisis of 2007-2010.
The third chapter focuses on “sovereign money reforms”, and in particular on the Swiss “Vollgeld initiative”, that advocate that the function of issuing and managing deposits be given entirely to the central bank. Contrary to the claims of the proponents of the reform, we find that the Vollgeld reform would have negative welfare effects.

The fourth chapter finds a novel rationale for the coexistence of deposits and lending in current banks, that speaks against narrow banking proposals. Thanks to the money properties
of deposits, interest on deposits is sticky. Banks performing maturity transformation are less exposed to the interest rate risk stemming from monetary policy, and cut lending less after an interest rate increase, than they would if they did not issue deposits.

HIMBERT Alexander - Three essays in regional and urban economics

The thesis deals with different questions about where exactly economic activity happens in geographical space. The main part of the thesis consists of two chapters that analyse which geographic regions in a country benefit most when a country trades more with its neighbor countries. In particular, the chapters investigate whether trade leads to previously poorer regions in remote areas catching up in development with rich urban centers or whether countries become more unequal following an increase in trade. While economic theory previously was not able to answer this question, the thesis shows that trade helps to poor regions to develop if they are located closely to international borders. This provides a strong argument for more international trade in the political discourse about the winners and losers of globalisation.

In a third chapter, I analyse how people bid for otherwise identical apartments located on different floors within a building. I find that the vertical location of an apartment plays a crucial role in explaining its price as people value both the easy access to the road on lower floors as well as the amenities coming with higher floors. Furthermore, we provide evidence that different social classes and income groups exhibit different preferences for vertical locations, which could in the future help to alleviate problems of gentrification in cities.


DANTON Jayson Marc - On the economics of housing consumption and finance

Households consume housing, food and clothing. Housing consumption is the result of a decision making process that is influenced by the surrounding economic environment. According to the Swiss Household Panel, the average share total annual household net income devoted to housing in 2000 (2014) was approximately 28% (31%). For households in the first decile of the income distribution, the average share was roughly 41% (49%), compared to 19% (20%) for households in the tenth decile. Similarly, in the USA, housing expenditure shares in 2014 amounted 41% and 30% for low-income and high-income households, respectively. In terms of financing, household mortgages represent a significant share of total Swiss domestic loans, amounting to around 85% as of 2018Q2. Using various econometric techniques and theoretical modelling, this thesis studies: (i) how local policy affects house prices through its effect on household location and tenure choices, and (ii) how changes in interest rates affect loan supply, given that most owner-occupiers finance their housing consumption via mortgage debt.


LAMBIRIS Mark - Three Essays on Economics Vulnerability

This thesis employs a number of statistical tools and economic theory to evaluate the causes and consequences of different types of vulnerability to economic shocks and circumstances. Different people may be more or less likely to be economically vulnerable for different reasons. Each of the three chapters of this thesis aims to examine a distinct source of economic vulnerability that reflects notable concerns to policy-makers in the twenty-first century.

Economic vulnerability may describe a demographic group which is systematically associated with economic disadvantage. Hence, the first chapter focusses on the vulnerability of a particular demographic group : immigrants. I examine how firms contribute to the systematic empirical observation that immigrants are paid lower wages than natives : and how firms respond after a large immigration shock to the host country. This chapter sheds light on how understanding the reasons behind the immigrant-native wage gap can help identifying the appropriate policy to tackle it.

An unfortunate stroke of nature, such as income loss, is an alternative source of economic vulnerability. The second chapter focusses on how the sudden loss of income affects the individual members of a community in contributing effort towards appropriating a resource shared by many groups. Understanding how income shocks affects group appropriation of the common resource sheds light on behaviour of communities and how their impoverishment can affect increasingly scarce resources such as water, oil or fisheries.

Finally, an individual may be vulnerable due to a personality trait or genetic feature which is expressed by behaviour leading to poor economic outcomes. The third chapter studies how anxiety impacts productivity and risk attitudes in a randomised control trial. Since anxiety is such a prevalent emotion in many aspects of daily life, such as the workplace, understanding what its economic costs are could prove useful in dealing with them.

VLACHOS Stephanos - On Exposure to Violence and Political Behaviour

The voting decision has an inherent ideological component. When choosing to cast their ballot for one candidate instead of another, individuals take into account both the economic policy platform and ideology. The choice on the ideological dimension is determined by the voter's values and beliefs. In recent years, a strand of literature has investigated the impact of violence on beliefs and political attitudes in conflict-torn countries. My thesis contributes to this literature by evaluating the effect of violence on in-group identification and political trust in developed countries, thus making a link between violence, political attitudes, and voting outcomes.

In "The legacy of war exposure on political radicalization" I examine the impact of war participation on identification with the polity and voting behaviour. I answer this question using a particular historical event: the forced conscription of men from the French eastern borderlands to the German military forces during World War II. In places where more men were conscripted, radical right-wing candidates still receive larger electoral shares today.

In "Seeds of Populism: Crime News Exposure and Anti-Immigration Politics", we study how news coverage of immigrants' criminality impacted voting patterns in the 2009 referendum on "Minaret Ban" in Switzerland. Our results imply that, should newspapers report foreigners' crime propensity at its true value, this would have decreased the "yes" vote by 4 percentage points.

In "Technological innovations in electoral campaigns: Direct canvassing and partisan mobilization" we argue that the main reason direct canvassing persists as a campaign strategy is because it is a very efficient mean to mobilize voters that are already supportive of a candidate's programme. We exploit a unique historical context: the first direct canvassing campaign by a presidential candidate in the 1896 election. Our findings imply that the electoral gain of the Democratic candidate can be attributed as 65% coming from increased mobilization, and 35% coming from persuasion.

HÄNNI Simon - Four Quasi-Experiments on Individual Motivation

What drives human behavior? This is the central question in behavioral economics and the answer is - naturally - context dependent. In this thesis I present four different quasi-experimental studies which each provide an insight into individual motivation in a specific environment. Quasi-experiments generally provide results that are easier to generalize than lab experiments but have inferior internal validity, due to a lack of explicit random assignment. Instead, they focus on situations where nature or institutions intervene and create exogenous variations that affect individuals differently. Quasi-experiments allow us to study a wide range of research topics. However, careful designs are necessary to cleanly identify effects despite the lack of experimental control. This often requires large data sets and strong interventions.

The four chapters exploit different quasi-experimental setups. Chapters one and two study spillovers of prosocial motivation among blood donors. Documenting and quantifying such spillover effects is highly policy relevant. Policy makers generally have a limited capacity for interventions. Thus, attributing these resources in the most effective way is crucial. Motivational spillovers can enhance the provision of public goods and affect the cost-benefit analysis of policy interventions. Chapter three looks at a potential factor that might harm pro-social motivation: A substantial fraction of blood donation attempts are rejected because they do not meet required donation criteria. Donors may perceive such rejections as social exclusion what could decrease their future motivation to donate. The last chapter of the thesis looks at a repeated competition setting. Repeatedly participating in competitions is essential for many life goals. Losing in such competitions may discourage individuals and make them postpone further competitions, thereby harming their future prospects.

While the four chapters study four quite different research questions on individual motivation, they all share similar underlying methods that allow to cleanly identify causal effects in natural settings.

JIANG Lingqing - Essays in Social Interaction and Agent Motivation

This thesis studies the role of social interactions on agent motivation. The first two chapters focus on prosocial motivation of voluntary blood donors who do not receive pecuniary incentives but social incentives from their peer groups. In Chapter 1, the peer groups are blood donors living in the same residence building. Chapter 2 extends the peer groups to donors in larger social networks. Chapter 3 uses a tournament setting where agents are not only motivated by high-stakes pecuniary incentives but also social incentives from their teammate. Chapter 4 investigates how social exclusions affect prosocial motivation of agents in a similar setting to in the first two chapters. All chapters use observational data and rely on the methods of instrumental variables to identify causal effects.

KLINKE Gian-Paolo - Three Essays in Applied Economic Geography

1. This chapter investigates the effect of asylum seekers hosting centers on nearby housing prices. We gather precise information on collective hosting centers, which we relate to a large dataset of housing transactions occurring in Switzerland over 2004-2014. We find a precisely estimated negative effect of 4.9% on the price for housing units located within 400 meters of an active center. Housing prices react less strongly in the proximity of police stations, which we interpret as evidence for perceived threats of increased crime as a relevant determinant for the observed housing price responses to hosting centers. However, we find no significant effect of the opening of centers on local crime rates. We also do not find evidence of price responses being driven by anti-immigrant political sentiment as expressed in a variety of referenda.

2. This chapter provides an account of the world's evolving economic geography by documenting employment growth patterns across 18,978 regions. These regions cover the main economies that together account for three quarters of global GDP, and we observe the period 1990-2010. We find that employment growth has been fastest in the world's densest regions. This flight to density has been accelerating over time and is driven by the growing importance of the non-agricultural sector in emerging economies. There are important differences between mature and emerging economies: whereas growth is fastest in the highest-density regions in emerging economies, it peaks for high medium density regions in mature economies.

3. This chapter studies the extent of spatial market integration among Brazilian municipalities. Relying on individual-level data from two rounds of the census, 2000 and 2010, I structurally estimate a set of parameters that capture the extent of regional market interactions and thereby provide evidence of the spatial frictions occurring between Brazilian municipalities.

HUANG Zhiyong - Validity of and Correction for Self-Report Measures in Surveys

This thesis consists of three papers on whether to use and how to use self-reported measures (for example, self-reported health) in social surveys.

Because it is cheap and easy to collect, the self-reported memory is routinely included in surveys and also widely used by general practitioners to evaluate the cognitive function of people. The first paper of the thesis examines whether the self-reported memory reflects the underlying cognitive function. Using data of middle-aged and older adults in China, we have found the self-reported memory is a relatively poor measure of cognitive function. Also, we have shown that individuals from different SES groups behave differently when reporting their memory condition.

The second paper proposes a new econometric model which makes self-reported health comparable between individuals. The new model is based on the premise of an influential theory of psychology and can be easily tested. I have compared this new model with the existing model through both simulations and analyses of real data. I have found the new model performs better than the existing model in general.

The third paper discusses how to use anchoring vignettes (a tool to align self-reported measures) in different ways. Firstly, we have studied the consequences when the econometric model used is not correct and proposed a new model which is more likely to be immune from the wrong model setup. We have done a large number of simulations which mimic different model setups.

SCHLEGEL Jan Christoph - Three Essays about Matching Markets

Matching models describe several real-world allocation problems that are not appropriately described by the classical competitive market model. Examples are the allocation of workers to firms, of students to colleges, or the matching of kidney-donor-pairs for life kidney donation. A central feature of these markets is that prices are not or not exclusively responsible to equate demand and supply. Pricing mechanisms cannot be used, since either monetary transfers are restricted or forbidden, since market participants are not profit maximizing, or because price taking behaviour is not plausible if market participants are very heterogenous.

In this thesis, we study, in three independent chapters, different theoretical aspects of matching markets and matching mechanisms. The first two chapters are motivated by theoretical questions in the design of clearing houses for entry-level labour markets. For these markets, we study allocation mechanisms with endogenous contracting. An allocation mechanism does not only determine which workers are matched to which firms, but also the contractual details of the labour relation. The third chapter studies the design of fair randomized admission procedures for the assignment of students to public schools.

In recent years, many real-world allocation problems have been studied within the paradigm of matching theory. Policy interventions in real world matching markets have been successful whenever they were informed by theoretical results. We are hopeful that the results in this thesis also find future applications in applied market design.

LEUTERT Jessica - Exchange Rate Dynamics and Unconventional Moneraty Policy

In the first chapter, I estimate the Swiss franc safety premium, defined as the compensation that investors require when they sell the presumably safe Swiss franc and in turn invest in a basket of foreign currencies. The three-step instrumental variable approach suggested by Maggiori (2013) yields unrealistic results and therefore does not work for Swiss franc. After some slight modification in the methodology, however, the results become more realistic and closer to those obtained when applying a GARCH approach. I find that the CHF safety premium is around 10% during crisis episodes.

In the second chapter1, we develop a simple two-country model with frictions in the banking sector. We identify three external sources of appreciation pressure : Financial frictions in the foreign investment market, financial frictions in the international credit market as well as capital inflows. In the two latter cases, foreign exchange interventions by the central bank can reverse the exchange rate movements. Under certain conditions, central bank purchases of bonds issued by firms (« credit easing ») can achieve this goal as well. The two policies, however, are likely to differ in their costs.

In the third chapter2, we analyse whether the SNB's policy measures to counter the appreciation of the Swiss franc before the introduction of the EUR/CHF lower bound were effective. We apply the so-called synthetic control approach which consists of building an artificial EUR/CHF exchange rate out of other exchange rates and safe assets that were not affected by the SNB's policy interventions. By comparing the actual EUR/CHF exchange rate after the intervention to its synthetic counterpart, we find that the March 2009 and August 2011 interventions were effective, while the spring 2010 interventions were not.

LAVANCHY Maude - Three Essays on the Labor Market of European Soccer Players

The three chapters of this thesis use the European soccer market as a laboratory to shed light on the implications transfer fees (i.e. compensations paid to an incumbent firm) can have in a more standard labor market.

This first chapter investigates the impact of transfer fees on wage determination, by constructing a model with two periods that reproduces salient features of the soccer market. The model predicts that, in a market where transfer fees apply, a worker gets a smaller wage and fewer opportunities to increase it. Moreover, imposing a regulation decreasing wages can increase transfer payments. Using a rich and unique database on the Italian first division, a structural estimation confirms the validity of the model.

The second chapter extends the model of Chapter 1 by adding the different labor life stages. While workers’ wages tend to increase with age and experience, transfer fees rather sharply decrease at the end of a worker’s career. These different profiles can be explained by experience effects, transfer opportunities and horizon effects. In addition, when a transfer fee must be paid, the worker’s wage is lower; however, due to the possibility of a future transfer, this negative effect is tempered in the middle of his career. Finally, being transferred as much as possible during his career maximizes the worker’s total life salary. If only one transfer occurs, an early transfer is more beneficial than a late one.

Finally, the third chapter explores, both theoretically and empirically, whether the worker-incumbent firm matching quality affects the strategic use of contracts as rent-seeking device (i.e. a device aiming at increasing the one’s share of profit without creating new wealth). Rent-seeking incentives are in fact reinforced in case of a mismatch. These behaviors may create inefficiencies, such as deterring future market entry or lowering investment incentives.

These results are not restricted to the world of European soccer. Contract clauses that prohibit a worker from working for a company’s rivals often include breach penalties which are very similar to the transfer fees observed in European soccer. 

PROBST Marcel - Three essays in empirical economics

This thesis contains three separate empirical papers. The first paper studies how local income tax rates, income tax bases and housing prices react to each other, by fitting a VAR model to data for 2,517 Swiss municipalities. We find a long-run elasticity of taxable income with respect to the local income tax rate of -0.08. The corresponding estimate based on households in the top-1% income category is -0.55. The reverse elasticity of tax rates with respect to exogenous changes in the tax base, is estimated at -0.07.

The second paper investigates how co-ethnic networks influence the Tiebout sorting behaviour of immigrant households that settle in Swiss municipalities. A new estimation approach is proposed to disentangle co-ethnic network effects from alternative location choice factors for each income category and family type. The results indicate that the importance of co-ethnic networks with respect to households' incomes follows an inverted U-shape. The lowest- income households seem to be predominantly attracted by criteria common to all immigrants. Thus, adverse selection originating from co-ethnic network effects may be less pronounced than what earlier findings suggest.

The third paper measures how greenhouse gas (GHG) policy stringency affects anthropogenic CO2 emissions, using a new GHG policy stringency indicator and a spatial VAR approach. Results indicate that a country with no GHG regulations can achieve an average reduction of 15% of its CO2 emissions by adopting the stringency level of the most regulated country. In addition, increasing GHG policy stringency improves sectoral CO2 efficiency, and decreases production in CO2 intensive sectors thereby altering the sectoral composition. Policy induced CO2 reduction costs in terms of GDP are relatively large compared to ex-ante cost reduction studies, but four times lower for developing compared to developed countries.

PREOTU Veronica - Essays on the economics of conflict and migration

Civil conflicts are dramatic events pushing individuals out of their home countries. But what if emigration itself worked as a pacifying force? In the first two chapters, I am interested into how emigration affects civil conflict incidence in the countries of origin. First, I construct a general equilibrium theoretical model of social conflict with emigration, where conflict results at equilibrium as the share of fighters in the economy. Emigration discourages fighting by reducing the prize to fight for, while increasing the opportunity cost of fighting. The main prediction of the model is that conflict decreases with the foreign wage net of migration costs. Second, I empirically test this prediction. By constructing a theory-driven instrumental variable, I show that emigration to developed countries decreases civil conflict incidence in origin countries. These findings point that, by opening their borders, host countries could contribute to saving the lives of the migrants as well as of those left home.

Moreover, civil conflicts destroy societies and traumatize the involved individuals, which increases the risk of a future conflict. In order to understand this vicious circle and find solutions for tackling it, the third chapter looks into whether the individuals exposed to conflict during their childhood are more likely to become violent later in life. The analysis focuses on asylum seekers in Switzerland since this group of immigrants are randomly allocated across cantons so they cannot self-select in a crime-promoting environment. The results show that indeed individuals exposed to civil conflicts or mass killings are more prone to develop an unlawful behavior later in life in comparison to their co-nationals born after conflict. Nevertheless, by analyzing the impact of public policies, we find that the implementation of friendly policies can break the vicious circle of violence persistence. In particular, offering labor market access and long-term perspectives to asylum seekers eliminates the risk of increased criminality.


CACAULT Maria Paula - Behavior and beliefs in networks

Since the 19th century, the use of mathematics to formally model hypotheses about behavior became an essential element in the economics research toolkit. Ever since, and for the sake of tractability, economists have simplified their models into sets of equations. The representative rational agent is, perhaps, the greatest simplification of the profession. 
During the first half of the 20th century, the study of games became popular among economists, who started moving away from the representative agent by acknowledging that people do not make decisions in isolation, but they take into consideration the decisions of others, whose objectives and beliefs may differ. However, rationality was still maintained in most economic models of behavior. It was until recent years that insights from psychology were introduced into economics to question the rationality assumption, giving raise to what we know as ``behavioral economics''. 
This thesis gravitates around the two departures from traditional economics mentioned above. On the one hand, people's behavior and beliefs are usually not determined by rational reasoning but their drivers need to be observed and understood. On the other hand, individuals do not make decisions in isolation but they consider the decisions of others, with whom they interact in potentially complicated ways. 
The different chapters show that, considering these two aspects of human interactions, leads to different outcomes than those predicted by traditional economic theory. In particular, that; i) coordination between people cannot be explained by rational responses to others’ actions, ii) cooperation is reduced if people cannot easily learn whether other people cooperate, iii) people can be altruist towards members of their groups, while being needlessly aggressive towards those outside their groups, and iv) people can be overconfident about the qualities of members of their group. Lastly, the thesis presents a statistical test for inference from network and experimental data.

JOYE Arnaud - Three essays on international trade and the labor market

The thesis is made of three independent chapters interested in the impact of globalization on workers in industrialized countries. The dissertation is especially focused on identifying the causal impact of international trade on workers’ mobility, wages, and employment with both a short- and medium-term perspective. The first paper explores the relation between intra-industry trade (IIT) expansion and associated worker flows, taking the latter as an indicator of labor-market adjustment costs. Being the first study to combine theoretical simulations and a novel identification strategy, we find that both theoretical and empirical analyses are consistent with the “smooth adjustment hypothesis", according to which IIT expansion is less disruptive than inter-industry trade expansion. The study therefore lends support to the use of IIT indices as first-pass proxies for the adjustment effects of trade expansion. The second chapter contrasts the impact of increased import competition coming from China and the European Union (EU) on workers in the United Kingdom over a 15-year period. The most salient findings show that increased imports from China had significantly negative effects on workers’ earnings, wages and employment. In contrast, larger imports from the EU are associated with positive worker-level outcomes, which is largely explained by the fact that increased imports from the EU were mostly offset by increased same-industry exports to the EU. Besides, we find that increased imports from China exert additional pressure on workers through spillovers to employment and wages in downstream industries. Finally, the last chapter is focused on the impact of exposure to trade and real exchange rate shocks on wages for Swiss manufacturing workers. A particular attention is made to consistently estimate the causal effect in using a two-step gravity-type identification strategy. The study shows that the impact of trade and exchange rate movements is concentrated among high-skilled workers almost exclusively.

BUFFAT Justin - Three essays in behavioral and experimental economics

The present PhD dissertation consists of three papers, organized in chapters, in the field of behavioral economics. This discipline studies economic behavior of individuals subject to limitations, such as bounded self-interest and bounded willpower. The behavior studied in the present thesis ranges from the complex decision to register as an organ donor, decision-making in the presence of uncertainty and the decision to give money to a charitable organization.

The first chapter aims at testing the effectiveness of an active-decision (AD) mechanism on the decision to become an organ donor in Switzerland, using field experiments. We found that stimulating participants’ reflection on the topic of organ donation had a negative effect on the decision to become an organ donor. Moreover, a non-binding commitment nudge reduces putting off the decision, but does not lead to donation rates higher than in the control group. The results suggest that AD may be far more limited than previously thought and raise doubts about the efficacy of engaging potential donors to reflect on the topic of organ donation.

Beyond carrying for others, behavioral economics also recognizes that individuals do not evaluate outcomes in absolute terms but rather by comparing them to some reference levels, called reference points. Above the reference points, economic outcomes are perceived as gains, while below these levels the same outcomes are felt as losses. The last two chapters analyze the importance of reference points in the evaluation of economic outcomes.  Using a laboratory experiment where subjects played two consecutive lotteries, Chapter 2 studies the speed of adjustment of the reference point. We find that varying the probability of winning the first lottery has no effect on subjects’ risk behavior regarding the second lottery. This result indicates a very fast adjustment of the reference point to the latest information. Chapter 3 investigates whether reference points are relevant for charitable preferences. Using actual donation decisions of participants in a laboratory experiment, the results suggest that reference points are not crucial for shaping charitable giving.

HARMS Annette - From reference points to internships: two essays in behavioural and experimental economics and one essay in labour economics

The beauty of the economic science lies in the interplay between theoretical models and empirical evidence. Economists have pushed the social science towards formalizing ideas to allow the derivation of behavioral predictions and hypothesis testing. New theories develop from simple intuitions, or evolve as extensions to existing models to explain empirical facts. The field of behavioural economics excels in challenging existing models through randomized controlled trials. Economic experiments simulate decision environments to understand the underlying psychological mechanisms, which drive behaviour. On the contrary, the field of labour economics uses clean data sources that allow analyses, as if situations were taking place in controlled environments.

The unifying theme of this thesis is to show how empirical results can challenge theoretical predictions and common sense intuitions.

The first two chapters analyse the role of expectations in reference point formation. People do not necessarily evaluate situations in absolute terms, but rather compare outcomes to certain anchors they can relate to, i.e. reference points. Kőszegi and Rabin (2006) put forward the idea that the reference point is formed through expectations. We analyse their implications theoretically, test it experimentally and show that the model fails in its key mechanisms. Expectations do not seem to be the key driver in reference-point formation as proposed by the KR-model.

Chapter 3 analyzes the popular phenomenon of the emerging “internship generation” using panel data. Ever more university graduates conduct internships in order to enter the regular labour market but their usefulness remains pending. Indeed, the results suggest that internships have detrimental effects on several dimensions. Graduates with an internship experience are less likely to be employed within one year of graduation, and if employed, they earn significantly less than their non-intern peers. Luckily, the negative effects are short-lived and vanish within five years.

SENN Julien - Three essays in behavioral and experimental economics

Behavioral Economics is concerned with increasing the psychological realism of mainstream Economics without impairing its formalism. It considers departures from the central assumptions characterizing the homo economicus, loosely termed rationality. This increase in realism often has the power to rationalize observational data considered as puzzling by the standard model. Experimental methods offer tools to the researcher to test such theories. In this thesis, behavioral models are formalized and tested using laboratory experiments.
In the first chapter, a model in which workers can exert productive effort and poaching effort (e.g. stealing a client to a colleague) is developed. Using an experiment, it is shown that individual-based incentives can trigger high levels of poaching which are detrimental to performance. Team-based incentives however do not have this property.
The second and the third chapters are centered on model of expectation-based reference-dependent preferences developed by K˝oszegi and Rabins (2006). They postulate that people evaluate outcomes with respect to a reference point : their expectations. In the second chapter, the question of the speed of adjustment of the reference point is tackled. The results suggest that the speed of adjustment of the reference point might depend on the size of the stakes at play. These results help understanding the conditions under which past beliefs and emotions should be expected to linger and to affect subsequent behavior.
The third chapter demonstrates that the K˝oszegi and Rabin model closely links myopic loss aversion to the endowment effect for risk. While myopic loss aversion can be replicated in a laboratory experiment, the endowment effect for risk is clearly rejected. These findings cast doubt on the ability of the KR model to provide a unifying theory of behavior under risk.


GERBER Mathieu - Four essays on sequential Monte Carlo and quasi-Monte Carlo methods
SIGNÉ Louis Alain - Studies of the interaction between health and financial allocations

This thesis studies the effects of health on financial decisions and on the short-run fluctuations of economic activity. The first paper analyses the effects of health status on household's portfolio choices; their decision to insure; their health and housing expenditures. Using data from the Panel Study of Income dynamics (PSID), the estimates highlights three results: 1) a significant effect of health on household's decisions, 2) a simultaneity in these decisions and 3) an evidence of health effects through the risk channel. Given these results, the second article explores the joint effects of health status and health-related risks on financial and health-related decisions. In so doing, this paper estimates the theoretical model of Hugonnier et al. (2013) on PSID data. The results show an effect of health through the income and risk channels. Mortality and morbidity risks impact the consumption, the investments in stocks and health insurance, and health expenditures decisions. Based on these empirical findings, the third paper explores the aggregate implications of health capital. This research develops a business cycle model in which agents are endowed with a stock of health capital and exposed to mortality and morbidity risks. Simulations reveal that this model fits well the business cycle stylized facts, as well as the cyclical patterns of health. In summary, these three studies suggest an active role for public health and insurance policies in the improvement of welfare. These policies may improve households' consumption and participation in the stock market. Further, they may contribute to smoothing economic fluctuations.

DELL'ERA Michele - Two essays on the impact of optimism on market outcomes and one essay on lobbying and reference dependence

This thesis consists of three chapters.
The rst chapter analyzes the implications of entrepreneurial optimism for equity market signaling. Project quality is signaled either by retaining shares (Leland and Pyle, 1977) or by retaining shares and underpricing (Grinblatt and Hwang, 1989). On the one hand the existence of optimistic entrepreneurs allows realistic entrepreneurs to insure idiosyncratic risk more, but on the other hand makes it less pro table to sell equity because the presence of optimists reduces stock prices. Entrepreneurial optimism makes entrepreneurs' worse o because it raises the cost of signaling. In contrast, it can make outside investors better o since it increases the volume of stocks that are underpriced.
The second chapter models the impact of optimism on occupational choice. In-dividuals choose to become entrepreneurs or employees. Competition in the en-trepreneurship and employment sectors determines an entrepreneur's probability of success and the wage of employees. Realistic individuals know the probability of succeeding as entrepreneurs, while optimists overestimate it. We nd that when there is a moderate or a high number of optimists in the economy the number of entrepreneurs (number of projects undertaken) raises, the number of employees low-ers, the probability of success of projects lowers, the interest rate on entrepreneur's borrowings raises, entrepreneurs borrow less and undertake projects of smaller size. We show that in this case optimism lowers the individual expected payo of entre-preneurs and raises the individual payo of employees.
The third chapter extends lobbying theory by assuming that the policymaker has reference dependent preferences: he derives utility not only from social welfare and contributions given by the lobby but also from deviations in the lobby's contributions from a reference level. We show that if the reference contribution is small and the policymaker is very responsive to contributions that are higher than the reference one, then the lobby obtains a more favorable policy o ering lower contributions. This result provides a new explanation for Tullock's paradox: the empirical fact that lobbying contributions are small relative to the value of the policies at stake.

DEGEN Kathrin - Evidence-based economic policy - three essays in applied microeconometrics

Evidence-based policy is understood as an approach that helps people make well informed decisions about policies and programs using systematic empirical evidence. The implementation of successful economic policy however requires a solid understanding of the causal effects of a policy intervention. Improvements in data quality, development of more robust estimation methods and better research designs have helped to develop a large toolkit of new instruments to identify causal effects of policies.

This thesis consists of three self-contained chapters in applied micro-econometrics. The first two chapters discuss related topics in labor economics. Both chapters rely on large administrative databases and use quasi-natural experiments to identify the causal effects of policy interventions using two distinct methodologies. While the first chapter focuses on a discussion of the empirical findings of reducing potential unemployment benefit duration on post-unemployment outcomes, the second chapter develops – inspired by job search theory – a new approach to learn about the relative importance of reservation wages for non-employment duration and survival probabilities. The third chapter is in the field of behavioral environmental economics and discusses the role of information for electricity consumption. This chapter is based on a randomized controlled field experiment and comes next to a purely randomized experiment situation. While the third chapter is not thematically linked to the first two chapters, all three chapters answer policy-relevant questions and contribute to a better understanding of the causal effects of economic policy interventions.

WAELCHLI Andreas - Essays on empirical banking and macroeconomics

The first chapter, TAF Effect on Liquidity Risk Exposure, measures how much the Federal Reserve's Term Auction Facility helped to decrease liquidity risk in banks. The paper stresses the importance of the liability term structure and provides empirical support to those arguments in favour of the introduction of liquidity risk measures in international financial regulations, as is now being done with the Basel III accords.

In the second chapter, TARP Effect on Bank Lending Behaviour: Evidence from the last Financial Crisis, we assess the question whether the government is capable to increase lending of the banking sector to the real sector. The main result suggest that banks that benefitted from the government sponsored Troubled Asset Relief Program (TARP) provide on average 19% higher loan originations to small businesses compared to other banks. This result is of particular interest to policy makers in the Euro Area, where lending to the real sector is still contained.

The third chapter is a theoretical contribution in the field of macroeconomics. In the paper Liquid Assets in a Cash-in-Advance Model, I analyse an extension to the cash-in-advance (CIA) model. While the CIA framework usually imposes that only money can be used for purchases, I relax that strong assumption and allow that also a real asset provides some degree of liquidity. The main finding is that if the asset is also liquid, then the asset is valued more than what its real return would suggest. The difference between the effective value in the model and the fundamental value can be interpreted as the liquidity premium of the asset. I also calculate under which circumstances the liquidity premium is positive.
