Book Description
The three essays in this thesis foster the identification of unexpected influences of different institutional arrangements on economic outcomes. The first two essays, experimental in nature, analyze the impact of two different contexts within Public Goods Games (PGG) environments. The first essay documents exact replications of four classic experiments in PGG and cast unexpected results in contribution behavior. First, it shows how the attenuation effect in replication studies, well documented in other disciplines, is also pervasive in experimental economics. Not all previous findings replicate, and effects found in successful replications are much smaller. Second, it shows that experimental context matters; experimental subjects in Texas tend to contribute more and free ride less, across different experiments. The second essay analyzes whether democratic institutions have any impact on agency problems where group members face a centralized arrangement of sanctioning power. It offers novel evidence, although a weak effect, of the intrinsic incentives for pro-social behavior attached to legitimacy in democratic institutions to promote collective action and higher economic efficiency. Finally, the last essay offers an empirical alternative to unravel heterogeneous unobserved traits on credit market customers. Through the use of mixture density estimation methods and rich administrative data, it identifies different quality-types of clients for credit demand and default decisions. Credit customers differ in their individual preferences, as well as levels of foresight, strategic behavior; all unobserved by the principal (lender). Accounting for these unobserved traits improves the forecast of potential clients' behavior and offers alternatives for different contracts and risk-pricing strategies to reduce credit rationing.

Book Description
"This thesis extends the macroeconomic theory with heterogeneous agents by taking account of heterogeneous households' interaction among themselves, in the form of comparing their consumptions or incomes, and by allowing heterogeneous firms to interact in a strategic fashion. In Chapter 2, I study how behavioral hypotheses such as the concern for status (relative consumption) and inequality aversion can lead to useful predictions about the evolution of wealth distribution and asset accumulation. Households are heterogeneous in terms of initial endowments and idiosyncratic shocks to their labor productivity. I propose a generalized concept of consumption externalities which include as special cases the concern for relative consumption, and preferences that display inequality aversion. In Chapter 3, I focus on interactions among heterogeneous firms in an oligopolistic framework. I assume that that the products offered by these firms are not perfect substitutes. More important, the degree of substitutability may vary across products within the industry. I offer a general formulation of industry structure such that monopoly, oligopoly, and monopolistic competition can be obtained as special cases. In Chapter 4, we study how preferences that display ambiguity aversion play a role in the job search process and affects the equilibrium rates of unemployment and vacancy. Ambiguity refers to the lack of information about probability distributions. The traditional job search model assumes that there are random matches between job seekers and firms (or vacancies), and the random draws have objective probability distributions that are known to both sides of the markets. We modify this model and assume that economic agents are uncertain about the underlying probability distributions. This chapter contributes to our understanding of how ambiguity aversion affects the unemployment rate and aggregate productivity." --

Book Description
This book is a collection of essays which examine how the properties of aggregate variables are influenced by the actions and interactions of heterogenous individuals in different economic contexts. The common denominator of the essays is a critique of the representative agent hypothesis. If this hypothesis were correct, the behaviour of the aggregate variable would simply be the reproduction of individual optimising behaviour. In the methodology of the hard sciences, one of the achievements of the quantum revolution has been the rebuttal of the notion that aggregate behaviour can be explained on the basis of the behaviour of a single unit: the elementary particle does not even exist as a single entity but as a network, a system of interacting units. In this book, new tracks in economics which parallel the developments in physics mentioned above are explored. The essays, in fact are contributions to the analysis of the economy as a complex evolving system of interacting agents.

Book Description
Recognising that the economy is a complex system with boundedly rational interacting agents, the book presents a theory of behavioral rationality and heterogeneous expectations in complex economic systems and confronts the nonlinear dynamic models with empirical stylized facts and laboratory experiments. The complexity modeling paradigm has been strongly advocated since the late 1980s by some economists and by multidisciplinary scientists from various fields, such as physics, computer science and biology. More recently the complexity view has also drawn the attention of policy makers, who are faced with complex phenomena, irregular fluctuations and sudden, unpredictable market transitions. The complexity tools - bifurcations, chaos, multiple equilibria - discussed in this book will help students, researchers and policy makers to build more realistic behavioral models with heterogeneous expectations to describe financial market movements and macro-economic fluctuations, in order to better manage crises in a complex global economy.

Book Description
Robert Aumann's career in game theory has spanned over research - from his doctoral dissertation in 1956 to papers as recent as January 1995. Threaded through all of Aumann's work (symbolized in his thesis on knots) is the study of relationships between different ideas, between different phenomena, and between ideas and phenomena. When you look closely at one scientific idea, writes Aumann, you find it hitched to all others. It is these hitches that I have tried to study.

Book Description
In traditional economics models of perfect competition agent's interactions are all mediated through the market. Interactions are anonymous, global and indirect. This is a powerful model, but we see many instances in which one, and sometimes all, of the previous characteristics fail to hold true. The type of agent you are, or your identity, can affect the type of interaction we have, and most surely the relationship between micro-behaviour and macro-phenomena in non-trivial ways. This book contains a selection of papers presented at the 6th Workshop on Economics with Heterogenous Interacting Agents (WEHIA). The contributions show that work done in other fields like evolutionary biology, statistical mechanics, social network theory and others help us to understand the way in which economic systems operate. Virtually all of the papers presented in this volume draw on some aspect or other of these varied approaches to related problems.

Book Description
This dissertation analyzes in four essays various issues of political conflicts, especially secessionist and proxy conflicts. In all four essays, I apply appropriate game theoretic models in order to analyze the strategic interactions of the conflicting parties. In the first essay, I investigate the occurrence of unravelling secessions. I analyze the conditions which lead to an unravelling process of secessions. My model shows that an initial secession increases the probability of consecutive conflicts. In the second essay, I investigate the role of a third party in ethnically motivated secessions when the secessionist group's objective is to merge with the third party. I analyze the conditions for third-party intervention and analyze how the participating player's behavior depends on heterogeneity costs, tax rate, sanctions, and fighting abilities. My model shows that a third party will only intervene if the secessionist region has a disadvantage in fighting and if the third party's potential gain from annexation is sufficiently high. In the third essay, I investigate the strategic behavior in proxy contests. I analyze the third parties' willingness to provide support for their respective allies. My model shows that conflict costs are irrelevant for the players' behavior if they receive support. In the last essay, my co-authors and I investigate conflicts with symmetric and asymmetric payoff structures. We analyze the participating agents' conflict behavior and compare their behavior in conflicts with symmetric and asymmetric payoff structures. Our model shows that conflicts with an asymmetric payoff structure are fought less intensively.
