In the standard model of dynamic interaction, players are assumed to receive public signals according to some exogenous distributions for free. We deviate from this assumption in two directions to consider an aspect of information structure in a more realistic way. We assume that signals are...

This research introduces the sequential bargaining to the standard screening model by allowing the agent to propose new contracts with strategic delay after the rejection of the principal's offer. We have found that if the difference between the types of agent are sufficiently large, the...

A fundamental non-stationarity of infinitely repeated games as usually studied is that the length of the history of play gets longer each period. With private actions (and mixed strategies) or private signals, this introduces a particular difficulty with common solution concepts such as...

We show that the ways incentives can be provided during dynamic interaction depend very crucially on the manner in which players learn information. This conclusion is established in a general stationary environment with noisy public monitoring and frequent actions. The monitoring process can be...

We analyze a version of Akerlof's market for lemons in which a sequence of buyers make offers to a long-lived seller endowed with a single unit for sale. We consider both the case in which previous offers are observable and the case in which they are not. When offers are observable, trade may...

We investigate the issue of implementation via individually rational ex-post budget-balanced Bayesian mechanisms. We demonstrate that all social choice rules that generate a nonnegative ex-ante surplus, including ex-post efficient ones, can generically be implemented via such mechanisms for any...

We study the endogenous formation of networks in a controlled experiment. Subjects derive benefits from being linked to others and incur costs for links they make. The theoretically predicted network has a "star"-type architecture, with "periphery" subjects linking to a unique "center". This...

We study a model of efficient risk sharing between two agents, A and B, who enjoy a non-durable common good. Only agent B can provide the common good whereas agent A can merely contribute indirectly by making transfers to the provider, agent B. We consider self-enforcing equilibria in the...
