Players coordinate continuation play in repeated games with public monitoring. We investigate the robustness of such equilibrium behavior with respect to ex-ante small private-monitoring perturbations. We show that with full support of public signals, no perfect public equilibrium is robust if...

This paper studies equilibrium selection in intertemporal coordination problems with delay options. The risk-dominant action of the underlying one-shot game is selected when frictions are arbitrarily small. Larger frictions introduce real option effects in the model and inhibit coordination.

Consider an exchange economy with asymmetric information. What is the set of outcomes that are consistent with common knowledge of rationality and market clearing?

This note extends Wiseman [6] to more general reputation games with exogenous learning. Using Gossner's [4] relative entropy method, we provide an explicit lower bound on all Nash equilibrium payoffs of the long-lived player. The lower bound shows that when the exogenous signals are sufficiently...

A player of privately known strength chooses when to enter a market, and an incumbent chooses whether to compete or concede. Information about the potential entrant's type is revealed publicly according to an exogenous news process and the timing of entry. I analyze stationary equilibria using...

This paper shows that a cartel that observes neither costs, prices, nor sales may still enforce a collusive agreement by tying each firm's continuation profit to the truncated current profits of the other firms. The mechanism applies to both price and quantity competition, and the main features...

A seller has an uncertain number of perishable goods to sell in each period. Privately informed buyers arrive stochastically to the market. Buyers are risk neutral, patient, and have persistent private values for consuming a single unit. We show that the seller can implement the efficient...

This paper demonstrates the theoretical foundation that underlies the willingness of rational arbitrageurs to delay and reinforce the speculative attack. The key assumptions are that there is a small probability that arbitrageurs are behavioral and never time the market of their own accord and...

We study the impact of unobservable stochastic replacements for the long-run player in the classical reputation model with a long-run player and a series of short-run players. We provide explicit lower bounds on the Nash equilibrium payoffs of a long-run player, both ex-ante and following any...

This paper proposes and studies a tractable subset of Nash equilibria, belief-free review-strategy equilibria, in repeated games with private monitoring. The payoff set of this class of equilibria is characterized in the limit as the discount factor converges to one for games where players...
