A country's form of government has important economic and political consequences, but the determinants that lead countries to choose either parliamentary or presidential systems are largely unexplored. This paper studies this choice by analyzing the factors that make countries switch from...

We study the role of inter-group differences in the emergence of conflict. In our setting, two groups compete for the right to allocate societys resources, and we allow for costly intergroup mobility. The winning group offers an allocation, that the opposition can either accept, or reject and...

We estimate the size and trend of the Egyptian shadow economy using two of the most common methods: the currency demand approach and the structural equation MIMIC model. To the best of our knowledge, this is the first comprehensive study to estimate the size of the shadow economy in Egypt during...

We study how natural-resource rents affect the risk of internal conflict within countries and how the federal structure of countries influences this relationship. Natural-resource abundance may induce excessive rent-seeking and thus increase the risk of internal conflict. Fiscal and political...

We consider a two period model in which an incumbent political party chooses the level of a current policy variable unilaterally, but faces competition from a political opponent in the future. Both parties care about voters payoffs, but they have different beliefs about how policy choices will...

Using a dynamic framework with strategic interactions, we study the management of a non-renewable natural resource when property rights are generally weak. Under generally weak property rights both the resource stock and the revenues from exploiting it are imperfectly protected, due to...

Differences between the voting behavior of men and women have become one of the most significant issues in social science research in recent years. In this study, we examine whether there is gender gap in voting behavior in Turkey. Using European Social Survey data, we find that education level...

My empirical results in Potrafke (2012) confirm past conclusions that Muslim-majority countries are less likely to be democratic. Hanusch takes issue with my results - and by inference with all past empirical results on the relation between Islam and democracy. In his comment on my study,...

This paper studies the factors driving changes in judicial independence (JI) as incorporated in constitutions. Two indicators of constitutionally safeguarded JI are constructed. Variations in these indicators are identified based on changes in the constitutions of as many as 100 countries that...

We present a novel approach for measuring democracy based on Support Vector Machines, a mathematical algorithm for pattern recognition. The Support Vector Machines Democracy Index (SVMDI) is continuously on the 0-1-interval and enables a very detailed measurement of democracy for 188 countries...
