"We present a model where a long run player is allowed to use both money transfers and threats to influence the decisions of a sequence of short run players. We show that threats might be used credibly (even in arbitrarily short repeated games) by a long-lived player who gains by developing a...

We offer a simple general equilibrium model to analyze how economy-wide forces (i.e. shocks to terms of trade, technology and endowments) will affect the intensity of social conflict over the distribution of resources. Examples of conflict activities range from crime to civil war. We show that...

We study the evolutionary robustness of strategies in innitely repeated prisoners' dilemma games in which players make mistakes with a small probability and are patient. The evolutionary process we consider is given by the replicator dynamics. We show that there are strategies with a uniformly...
