This paper has investigated the asymmetric policies of information sharing in duopoly. We built on the classic model of Gal-Or (1985), extended to allow different precisions of firms' private information, as Gal-Or (1985) suggested in her conclusion. We find that asymmetric equilibria will...

We consider repeated games with private monitoring that are 'close' to repeated games with public/perfect monitoring. A private monitoring information structure is close to a public monitoring information structure when private signals can generate approximately the same distribution of the...

Under appropriate assumptions (private values and uniform punishments), the Nash equilibria of a Bayesian repeated game without discounting are payoff-equivalent to tractable, completely revealing, equilibria and can be achieved as interim cooperative solutions of the initial Bayesian game. This...

We analyze the extent to which efficient trade is possible in an ongoing relationship between impatient agents with hidden valuations (i.i.d. over time), restricting attention to equilibria that satisfy ex post incentive constraints in each period. With ex ante budget balance, efficient trade...

We examine multistage information transmission with voluntary monetary transfer in the framework of Crawford and Sobel (1982). In our model, an informed expert can send messages to an uninformed decision maker more than once, and the uninformed decision maker can pay money to the informed expert...

We analyze a cheap talk model in which an informed sender and an uninformed receiver engage in finite-period communication before the receiver chooses a project. During the communication phase, in each period, the sender sends a cheap talk message and the receiver voluntarily pays money for the...

For repeated games with noisy private monitoring and communication, we examine robustness of perfect public equilibrium/subgame perfect equilibrium when private monitoring is close to some public monitoring. Private monitoring is close. to public monitoring if the private signals can generate...

We introduce a class of two-player dynamic games to study the effectiveness of screening in a principal-agent problem. In every period, the principal chooses either to irreversibly stop the game or to continue, and the agent chooses an action if the principal chooses to continue. The agent's...

When the information used by a principal to monitor an agent is private, and thus non-verifiable by a third party, the principal has a credibility issue with the agent. The agent should be concerned that the principal could misrepresent the information in order to collect a monetary penalty from...

This paper investigates the relationship between the existence of equilibria in behavioral strategies, perfect recall, and notions of convexity in extensive form games. The central result is that players possess perfect recall if and only if their sets of behavioral strategies are behavioral...
