We show how an outside party offering incentives to voters can manipulate at no cost collective decisions made through voting. Under influence, these decisions can become inefficient. Therefore, the market for policies may be more likely to fail than the markets for goods, because (democratic)...

In the classical Condorcet jury model, different jurors votes are independent random variables, where each juror has the same probability p1/2 of voting for the correct alternative. The probability that the correct alternative will win under majority voting converges to 1 as the number of jurors...

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...

We show how an outside party offering incentives to voters can manipulate at no cost collective decisions made through voting. Under influence, these decisions can become inefficient. Therefore, the market for policies may be more likely to fail than the markets for goods, because (democratic)...

When optimal policymaking is subject to dynamic inconsistencies (Kydland and Prescott, 1977), but shocks hit the economy after private agents form expectations, there is a trade off between the need to commit to a policy, and the need to retain discretion so as to respond to shocks. Rogoff...

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,...

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...
