Can campaign communications credibly transmit information about candidates' policy intentions? To answer this question, I develop and analyze a game-theoretic model of campaign communication in a two-candidate majority rule election with multidimensional policies. Candidate and voter preferences...

Party activists wish to (i) advocate the best policy and yet (ii) unify behind a common party line. An activist's understanding of his environment is based on the speeches of party leaders. A leader's influence, measured by the weight placed on her speech, increases with her judgement on policy...

We study a model of strategic persuasion based on the theory of cheap talk, in which a better-informed agent manipulates two decision-makers’ joint decision on alternative proposals. With the heterogeneity of two decision-makers’ value of the outside option, only the decision-maker with the...

We continue the work of Aumann (Ann. Statist. 4 (1976), 1236-1239), Geanakoplos and Polemarchakis (J. Econ. Theory 28 (1982), 192-200) on common knowledge and consensus, reconsidering the arguments and the findings of both Aumann (1976) and Geanakoplos and Polemarchakis (1982) and offering...

This paper studies repeated communication regarding a multidimensional collective decision in a large population. When preferences coincide but beliefs about the consequences of the various decisions diverge, it is shown, under some specific assumptions, that public communication causes the...

We develop a model of strategic information transmission from an outside expert with informational superiority to a group of people who make a decision by voting on a proposal. An outside expert who observes the qualities of a proposal sends a cheap talk message to decision makers with limited...

We develop a model of strategic information transmission from an expert with informational superiority to decision makers who vote on a proposal. We show that an expert's simple cheap talk strategy can be surprisingly effective in persuading decision makers by polarizing or unifying their...

This paper studies when introducing verifiable communication choices between agents in a cheap-talk benchmark setting, with social tie, is beneficial to welfare. In our model agents have two ways to communicate their private information: either through a costly verifiable information (hard) link...

We analyze the interaction between the incentives for free-riding and information revelation among partners in a dynamic setting. Partners contribute to the value of a common project, but have private information about the success of their own contribution efforts. The desire to maintain a...

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...
