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...

Previous analyses of the formation and composition of community based organizations (CBOs) have used cross section data.  So, causal inference has been compromised.  We obviate this problem by using data from a quasi-experiment in which villages were formed by government officials selecting...

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...

Using data from a field experiment conducted in seventy Colombian municipalities, we investigate who pools risk with whom when risk pooling arrangements are not formally enforced.  We explore the roles played by risk attitudes and network connections both theoretically and empirically.  We...

This paper describes and analyzes the results of a unique field experiment especially designed to test the effects of the level of commitment and information available to individuals when sharing risk.  We find that limiting exogenously provided commitment is associated with less risk sharing,...

For over a quarter of a century, the use of utility information based upon interpersonal comparisons has been seen as an escape route from the Arrow Impossibility Theorem. This paper critically examines this informational basis approach to social choice. Even with comparability of differences...

This paper offers a simple but rich framework to study communication subject to various constraints such as anonymity requirements, equal treatment of multiple agents, overconfidence of an expert, and garbling, by extending the cheap talk model of Crawford and Sobel (1982). Common to these...

Drawing on the so-called `doctrinal paradox`, List and Pettit (2002a) have shown that, given an unrestricted domain condition, there exists no procedure for aggregating individual sets of judgments over multiple interconnected propositions into corresponding collective ones, where the procedure...
