This paper studies the impact of interaction topologies on individual and aggregate behavior in environments with social interactions. We study social interaction games of an infnitely large population with local and global externalities. Local externalities are limited within agents'...

We study two person-betting games with inconsistent commonly know beliefs, using an experimental approach. In our experimental games, participants bet against one another, each bettor choosing one of two possible outcomes, and payoff odds are know at the time bets are placed. Bettors’ beliefs...

This paper considers a population of agents that are engaged in a listening network. The agents wish to match their actions to the true value of some uncertain (exogenous) parameter and to the actions of the other agents. Each agent begins with some initial information about the parameter and,...

We study mechanism design under endogenously incomplete commitment as it arises in contracting with escape clauses. An escape clause permits the agent to end a contractual relationship under specified circumstances, after which the principal can offer an ex-post contract. Escape clauses are...

Although it is generally accepted that consumer confidence measures are informative signals about the state of the economy, theoretical macroeconomic models designed for the analysis of monetary policy typically do not provide a role for them. I develop a framework with asymmetric information in...

Consider an investment problem with strategic complementarities and incomplete information about returns. This paper shows that investors aggregate their private information in equilibrium by trading a token and observing its market price over multiple rounds before making the investment...

This paper introduces a theory of market incompleteness based on the information transmission role of prices and its adverse impact on the provision of insurance in financial markets. We analyse a simple security design model in which the number and payoff of securities are endogenous. Agents...

This paper analyzes the signaling effect of bidding in a two-round elimination contest. Before the final round, bids in the preliminary round are revealed and act as signals of the contestants' private valuations. Depending on his valuation, a contestant may have an incentive to bluff or sandbag...

We characterize full implementation of social choice sets in mixedstrategy Bayesian equilibrium. Our results concern both exact and virtual mixed implementation. For exact implementation, we identify a strengthening of Bayesian monotonicity, which we refer to as mixed Bayesian monotonicity. It...

In recent years there has been a growing interest in macro models with heterogeneity in information and complementarity in actions. These models deliver promising positive properties, such as heightened inertia and volatility. But they also raise important normative questions, such as whether...
