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...

In a world of trade restrictions, large countries enjoy economic benefits, because political boundaries determine the size of the market. Under free trade and global markets even relatively small cultural, linguistic or ethnic groups can benefit from forming small, homogeneous political...

This paper shows that smaller countries have a larger share of public consumption in GDP, and are also more open to trade. These empirical observations are consistent with recent theoretical models explaining country formation and break up, and may account for the observed positive empirical...

A fundamental aspect of institutional design is how much society chooses to delegate unchecked power to its leaders. If, once elected, a leader cannot be restrained, society runs the risk of a tyranny of the majority, if not the tyranny of a dictator. If a leader faces too many ex post checks...

This paper examines the process of European political integration. We start with a political-economy model of monetary policy, illustrating a general principle: economic integration requires setting up European institutions endowed with the authority to enact Europe-wide policies. On the other...

This paper studies the choice of electoral rules and 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 U.S. cities, particularly...

We provide new measures of ethnic, linguistic, and religious fractionalization for about 190 countries. These measures are more comprehensive than those previously used in the economics literature and we compare our new variables with those previously used. We also revisit the question of the...

This paper studies what determines group formation and the degree of participation when the population is heterogeneous, both in terms of income and race or ethnicity. We are especially interested in whether and how much the degree of heterogeneity in communities influences the amount of...

We survey and assess the literature on the positive and negative effects of ethnic diversity on economic policies and outcomes. Our focus is on communities of different size and organizational structure, such as countries, cities in developed countries, and villages and groups in developing...
