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...

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...

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...

Around the world one observes a tendency toward political separatism. The economic literature generally (but not always) emphasizes several benefits of large fiscal (and, therefore, political) jurisdictions. In this paper we discuss several politico-economic arguments which reconcile this...

This paper provides a formal model of endogenous border formation and choice of defense spending in a world with international conflict. We examine both the case of democratic governments and of dictatorships. The model is consistent with three observations. First, breakup of countries should...

This paper studies the relationship between international conflict and the size distribution of countries in a model in which both peaceful bargaining and nonpeaceful confrontations are possible. We show how the size distribution of countries depends on the likelihood, benefits, and costs of...

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 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...

This paper considers the interaction of two parties with different objectives concerning inflation and unemployment and rational and forward-looking wage-setters. If discretionary policies are followed, an economic cycle related to the political cycle results in equilibrium. This cycle is...
