We investigate the causes of civil war, using a new data set of wars during 1960-99. We test a greed theory focusing on the ability to finance rebellion, against a grievance theory focusing on ethnic and religious divisions, political repression and inequality. We find that greed considerably...

History offers many examples of dictators who worsened their behavior significantly over time (like Zimbabwe's Robert Mugabe), while there are also cases of dictators who have displayed remarkable improvements (like Jerry Rawlings of Ghana).  We show that such mutations can result from rational...

Following the wave of democratization during the 1990s, elections are now common in low-income societies.  However, these elections are frequently flawed.  We investigate the Nigerian general election of 2007, which is to date the largest election held in Africa and one seriously marred by...

We model the choice of leaders of groups within society, where leaders influence both the mode of interaction between groups (either peaceful compromise or costly conflict) and the outcome of these interactions. Group members may choose leaders strategically/instrumentally or they may choose...

In an asymmetric war of attrition the players` prize valuations are drawn from different distributions. A stochastic strength ordering, based upon relative hazard rates, is used to rank these distributions. The stochastically stronger player is perceived to be strong ex ante, even though her...

The Soviet Union was able to develop a large military-industrial complex and become the world’s second superpower despite the small size of its malfunctioning planned economy because defence was given high priority status and special planning, rationing and administrative mechanism were...

Post-conflict situations face a high risk of reversion to conflict. We investigate the effect of military expenditure by the government during the first decade post-conflict on the risk of reversion. We contrast two theories as to the likely effects. In one, military spending deters conflict by...

We study in-group favouritism and out-group discrimination in a multiplayer dictator game.  An allocator divides a large sum of money among three groups of 20 recipients each and Self.  Allocations to groups are divided equally among the group members.  The three groups are supporters of the...

A new game theoretic analysis of finite horizon, complete information bargaining is advanced. The extensive form reflects an attempt to model unstructured negotiations, in which the negotiants can gain no artificial advantage from the details of the bargaining protocol. Conditions are identified...

In the past 30 years, microfinance has carried many promises of social and economic transformation, with the shift towards targeting women being seen as a major strategic move through which the promise of social development could be most effectively delivered.  However, ethnographic studies...
