Consider two agents who learn the value of an unknown parameter by observing a sequence of private signals. Will the agents commonly learn the value of the parameter, i.e., will the true value of the parameter become approximate common-knowledge? If the signals are independent and identically...

The author solves for the reputational equilibrium in a class of linear quadratic Gaussian dynamic games with noisy control. This equilibrium is particularly simple to describe and tractable. There is imperfect monitoring but a sequential equilibrium is found where the uninformed agents always...

We analyze a game of strategic experimentation with two-armed bandits whose risky arm might yield payoffs after exponentially distributed random times. Free-riding causes an inefficiently low level of experimentation in any equilibrium where the players use stationary Markovian strategies with...

Three designs of auctions with quality thresholds are considered. The quality threshold is not known with certainty by the bidders. In one scheme, quality plans submitted by potential bidders are evaluated first and price bids for only those plans that have been approved are invited. The second...
