While several cross-sectional studies (La Porta et. al. 2002, Norton 2002) examine institutional and cultural determinants of economic freedom, changes in economic freedom remain unexamined. I construct a measure of median voter preferences and find changes in voter preferences for economic...

For groups that must make several decisions of similar form, we define a simple and general mechanism that is designed to promote social efficiency. The mechanism links the various decisions by forcing agents to budget their representations of preferences so that the frequency of preferences...

This paper develops a positive analysis of stable group formation, highlighting the role of conflict management within groups. The analysis is based on a model of sequential conflict, starting with a "winner- take-all" contest for control of some resource. When a group forms, members pool their...

This paper considers an economy where groups compete in a contest for power to redistribute future income in their favor. An increased external threat of terrorism--either an increase in the likelihood of a successful terrorist attack or a greater loss of income in the event of a successful...

This paper develops a positive analysis of alliance formation that builds on a simple economic model featuring a “winner-take-all” contest for control of some resource. When an alliance forms, members pool their efforts in that contest and,if successful, apply the resource to a joint...

This paper studies dynamic, endogenous institutional change. We introduce the class of dynamic political games (DPGs), dynamic games in which future political aggregation rules are decided under current ones, and the resulting institutional choices do not affect payoffs or technology directly. A...

This paper examines existence of Markov equilibria in the class of dynamic political games (DPGs). DPGs are dynamic games in which political institutions are endogenously determined each period. The process of change is both recursive and instrumental: the rules for political aggregation at date...

We examine how globalization affects trade patterns and welfare when conflict prevails domestically. We do so in a simple model of trade, in which a natural resource like oil is contested by competing groups using real resources ('guns'). Thus, conflict is viewed as ultimately stemming from...

We present a general model of two players contest with two types of efforts. Contrary to the classical models of contest, where each player chooses a unique effort, and where the outcome depends on the efforts of all the players, contestants are allowed to reduce the effort of the opponent....
