Coordination failures are at the heart of development traps. Although communication can reduce such failures, to date experimental evidence has primarily been lab based. This paper studies the impact of communication in stag hunt coordination games played by members of Senegalese farmer groups...

This paper considers mechanism design problems in environments with ambiguity-sensitive individuals. The novel idea of the paper is to introduce ambiguity in mechanisms so as to exploit the ambiguity sensitivity of individuals. We prove a revelation principle for the partial implementation of...

The paper considers the communication complexity (measured in bits or real numbers) of Nash implementation of social choice rules. A key distinction is whether we restrict to the traditional one-stage mechanisms or allow multi-stage mechanisms. For one-stage mechanisms, the paper shows that for...

Consumers can often allocate resources to the provision of local public goods and to the provision of global public goods. This paper reports a public goods experiment in which participants allocated tokens to a local exchange with a relatively high marginal payoff and a global exchange with a...

The goal of this paper is to introduce communication in a collective choice environment with information acquisition. We concentrate on decision panels that are comprised of agents sharing a common goal and having a joint task. Members of the panel decide whether to acquire costly information or...

Modern central banks do not only announce the interest rate decision, they also communicate a "story" that explains why they reached the particular decision. When decisions are made by a committee, it could be difficult to find a story that is both consistent with the decision and representative...

A common finding of the literature on dishonesty is that groups are moredishonest than individuals. We revisit this finding by making explicit thethird-party harmed by subjects' dishonesty: a local charity. With this explicitthird-party, we do not find groups to be more dishonest than...
