Trade liberalization and political separatism go hand in hand. In a world of trade restrictions, large countries enjoy economic benefits because political boundaries determine the size of the market. In a world of free trade and global markets even relatively small cultural, linguistic or ethnic...

This paper revisits the empirical evidence on the relationship between economic integration and economic growth. First, we present an updated dataset of openness indicators and trade liberalization dates for a wide cross-section of countries in the 1990s. Second, we extend the Sachs and Warner...

This paper presents a framework to understand and measure the effects of political borders on economic growth and per capita income levels. We present a model providing a theoretical foundation to estimate empirically the effects of political borders on growth. In our model, political...

We investigate how criminal organizations strategically use violence to influence elections in order to get captured politicians elected. The model offers novel testable implications about the use of pre-electoral violence under different types of electoral systems and different degrees of...

We use recent immigration data from 195 countries and propose an index of population diversity based on people's birthplaces. This new index is then decomposed into a size (share of foreign born) and a variety (diversity of immigrants) component and is available for 1990 and 2000 disaggregated...

The present paper argues that the correct experiment to evaluate the effects of a fiscal adjustment is the simulation of fiscal plans rather than of individual fiscal shocks. The simulation of the fiscal plans adopted by 16 OECD countries over a 30-year period supports the hypothesis that the...

Why do countries delay stabilizations of large and increasing budget deficits and inflation? And what explains the timing of reforms? We use the war of attrition model as a guidance for our empirical study on a vast sample of countries. We find that stabilizations are more likely to occur when...

The poor favor redistribution and the rich oppose it, but that is not all. Social mobility may make some of today's poor into tomorrow's rich and since redistributive policies do not change often, individual preferences for redistribution should depend on the extent and the nature of social...
