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 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...

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...

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...

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,...

This paper overviews theoretical and empirical contributions that study political borders from an economic perspective. It reviews theories of the number and size of nations focused on the trade-off between economies of scale in public-good provision and heterogeneity of preferences over public...

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...
