The book provides a simple, intuitive introduction to regression models for qualitative and discrete dependent variables, to sample selection models, and to event history models, all in the context of maximum likelihood estimation. It presents a wide range of commonly used models. The book thereby enables the reader to become a critical consumer of current empirical social science research and to conduct own empirical analyses. The book includes numerous examples, illustrations, and exercises. It can be used as a textbook for an advanced undergraduate, a Master`s or a first-year Ph.D. course in microdata analysis, and as a reference for practitioners and researchers.

This book concentrates on how small European countries coped with economic integration and disintegration during the twentieth century. Small countries had to adapt flexibly to the drastically changing conditions outside their borders. They had to find ways of maintaining their political autonomy notwithstanding their economic dependence, and they have been quite successful in accomplishing this difficult balancing act. The authors analyse how small countries responded to the challenges of the international system and describe the different policies and strategies pursued by governments, industries and firms. Originating from the XIII. Congress of the International Economic History Association (IEHA), the contributions to this volume offer new perspectives on a widely debated topic and contribute to a better understanding of the current process of globalisation in small and large countries. The volume is divided into three sections: I. Coping with Different Regimes for International Trade and Changing Competitiveness; II. From an Open World Economy to Economic Disintegration and Protectionism; III. Trade Liberalisation, European Integration and Deregulation.

Most economic models are limited to analyzing the behavior of a representative agent and, consequently, make the implicit assumption that either individuals are homogeneous
or that individual heterogeneity does not matter for the aggregate outcome. However, recent empirical evidence in experimental economics indicates that under strategic complementarity a minority of irrational agents may, indeed, drive the market's outcome. To avoid potential aggregation bias, researchers in empirical economics should take individual heterogeneity into account, which results in the following trade-off: on the one hand, a representative agent approach, which is parsimonious and easy to interpret, completely neglects heterogeneity, but on the other hand, estimating economic behavior at the individual level, which requires a lot of parameters and results in a plethora of estimates, may demand too much from the data. To escape this dilemma, empirical economists may apply finite mixture models, which offer a compromise between completely ignoring individual heterogeneity and running into difficulties when estimating individual by individual. This thesis comprises four independent applications of finite mixture regression models. The first three experimental studies are part of a comprehensive research project, funded by the Swiss National Science Foundation, and discuss the identification and stability of
two different behavioral types of decision makers in the domain of risk. The last essay applies a finite mixture model to the German Socio-Economic Panel to segregate the share of altruists from the rest of the population which is assumed to be selfish.

Deutsche Zusammenfassung: Die in der experimentellen Wirtschaftsforschung gängigen ökonometrischen Modelle schätzen häufig das Verhalten eines repräsentativen Individuums. Dem liegt die implizite Annahme
zu Grunde, dass sich die Individuen entweder homogen verhalten, oder aber individuelle Heterogenität keinen Einfluss auf das aggregierte Verhalten ausübt. Neuere empirische und theoretische Evidenz zeigt jedoch, dass in imperfekten Märkten - insbesondere unter strategischer Komplementarität - eine Minderheit irrationaler Agenten das Marktgleichgewicht stark beeinflussen kann. Um Verzerrungen bei der Aggregation zu vermeiden, sollten in solchen Situationen individuelle Unterschiede zwingend berücksichtigt werden. Typischerweise stehen aber bei Experimentaldaten zu wenige Beobachtungen pro Individuum
zur Verfügung, um komplexe Verhaltensmodelle auf individueller Ebene schätzen zu können. Finite Mixture Modelle bieten hier einen guten Kompromiss zwischen einem
Repräsentativen Agenten Modell und einer Schätzung auf individueller Ebene: Sie erlauben es eine bestimmte Anzahl Verhaltenstypen zu identifizieren und jedes einzelne
Individuum endogen einem dieser Verhaltenstypen zuzuordnen. Damit erfassen sie einerseits den entscheidenden Teil der individuellen Heterogenität, nämlich die Existenz verschiedener Verhaltenstypen, und benötigen andererseits deutliche weniger Parameter als eine Schätzung auf individueller Ebene.

Diese Arbeit umfasst vier unabhängige Anwendungen von Finite Mixture Modellen. Die ersten drei experimentellen Studien sind Teil eines vom Schweizerischen Nationalfonds
unterstützten Forschungsprojekts zur Charakterisierung verschiedener Verhaltenstypen bei Entscheidungen unter Risiko. In der vierten Studie wird mit einem Finite Mixture
Modell der Anteil an Altruisten in einer Teilstichprobe des Deutschen Haushaltspanels identifiziert.

This paper examines the cyclical interactions between the remittances of Turkish workers in Germany and output in both Turkey and Germany. Our analysis introduces a new data set covering 1962 to 2004, never used before in the research literature and considered to be a more reliable source than the data sets used in other studies. By dividing the original sample into recruitment, family reunification, and naturalization periods, we show that the duration of migrants' stay in the host country affects the direction and strength of the relation between remittances and the host and home countries' business cycles.

Bei der Finanzierung der Spitäler soll die Einführung von Fallpauschalen Anreize für möglichst effizientes Arbeiten setzen. Die Autoren des folgenden Beitrags legen dar, dass die in der Praxis im Kanton Zürich gewählten Ansätze nicht unbedingt die Effizienten belohnen, weil die Spezialisierung bzw. der «Produktemix» der Spitäler vernachlässigt wird.
