We argue that migrants played a significant role in the diffusion of the demographic transition from France to the rest of Europe in the late 19th century. Employing novel data on French immigration from other European regions from 1850 to 1930, we find that higher immigration to France...

We discuss a wide range of measures of social heterogeneity, both theoretically and empirically. In our framework, individuals who differ from each other either in terms of their identity traits or of their cultural values experience antagonism toward each other. Depending on the type of...

Current surpluses in the U.S. have been achieved by a combination of a strong economy, low interest rates, and sharp cuts in defence spending. These surpluses follow a period (the eighties) of rather exceptional budget deficits. This paper investigates the origin, size, and expected future...

Bigger governments raise the possibilities for corruption; more corruption may in turn raise the support for redistributive policies that intend to correct the inequality and injustice generated by corruption. We formalize these insights in a simple dynamic model. A positive feedback from past...

Americans average 25.1 working hours per person in working age per week, but the Germans average 18.6 hours. The average American works 46.2 weeks per year, while the French average 40 weeks per year. Why do western Europeans work so much less than Americans? Recent work argues that these...

This paper studies the choice of electoral rules, in particular, the question of minority representation. Majorities tend to disenfranchise minorities through strategic manipulation of electoral rules. With the aim of explaining changes in electoral rules adopted by US cities (particularly in...

In this paper, we present our view of the recent evolution of European integration. We first briefly describe the main features of the institution and decision making process in the European Union, with particular attention to the debate between federalists and super nationalists. We then...

We survey and assess the literature on the positive and negative effects of ethnic diversity on economic policies and outcomes. Our focus is on both focus both cities in developed countries (the US) and villages in developing countries. We also consider the endogenous formation of political...

Policies are typically chosen by politicians and bureaucrats. This paper investigates the e fficiency criteria for allocating policy tasks to elected policymakers (politicians) or non elected bureaucrats. Politicians are more efficient for tasks that do not involve too much specific technical...

We use data on announced and actual exchange rate arrangements to ask which countries follow de facto regimes different from their de iure ones, that is, do not do what they say. Our results suggest that countries with poor institutional quality have difficulty in maintaining pegging and abandon...
