We investigate the determinants of the fertility decline in Europe from 1830 to 1970 using a newly constructed dataset of linguistic distances between European regions. We find that the fertility decline resulted from a gradual diffusion of new fertility behavior from French-speaking regions to...

In this paper we present a conceptual framework linking cultural heterogeneity to inter-group conflict. When conflict is about control of public goods, more heterogeneous groups are expected to fight more with each other. In contrast, when conflict is about rival goods, more similar groups are...

We explore the interrelationships between various measures of cultural distance. We first discuss measures of genetic distance, used in the recent economics literature to capture the degree of relatedness between countries. We next describe several classes of measures of lin-guistic, religious,...

We develop a theory of interstate conflict in which the degree of genealogical relatedness between populations has a positive effect on their conflict propensities because more closely related populations, on average, tend to interact more and develop more disputes over sets of common issues. We...

The empirical literature on economic growth and development has moved from the study of proximate determinants to the analysis of ever deeper, more fundamental factors, rooted in long-term history. A growing body of new empirical work focuses on the measurement and estimation of the effects of...

We quantify the impact of barriers to international investment, using a novel multi-country dynamic general equilibrium model with heterogeneous investors and imperfect capital mobility. Our model yields a gravity equation for bilateral foreign asset positions. We estimate this gravity equation...

This paper discusses the process of European institutional integration from a political-economy perspective, linking the long-standing political debate on the nature of the European project to the recent economic literature on political integration and disintegration. First, we introduce the...

Why is modern society capable of cumulative innovation? In A Culture of Growth: The Origins of the Modern Economy, Joel Mokyr persuasively argues that sustained technological progress stemmed from a change in cultural beliefs. The change occurred gradually during the seventeenth and eighteenth...

Europe's monetary union is part of a broader process of integration that started in the aftermath of World War II. In this "political guide for economists" we look at the creation of the euro within the bigger picture of European integration. How and why were European institutions established?...

This paper reviews the economics approach to conflict and national borders. The paper (a) provides a summary of ideas and concepts from the economics literature on the size of nations; (b) illustrates them within a simple analytical framework where populations fight over borders and resources,...
