Reputation systems constitute an important institution to help sustain trust in online auction markets. However, only half of buyers leave feedback after transactions, and nearly all of it is positive. In this paper, I propose a mechanism whereby sellers can provide rebates (not necessarily in...

We present a simple algorithm for computing an intuitive notion of MPE for finite state dynamic games with asymmetric information. The algorithm does not require: storage and updating of posterior distributions, explicit integration over possible future states to determine continuation values,...

We consider the effect a public revelation of information (e.g. rating, grade) has on signaling and trading in a dynamic model. Competing buyers offer prices to a privately informed seller who can reject these offers and delay trade. This delay is costly and the seller has no commitment to the...

We propose a learning dynamic with agents using samples of past play to estimate the distribution of other players' strategy choices and best responding to this estimate. To account for noisy play, estimated distributions over other players' strategy choices have full support in the other...

This paper studies an evolutionary model of network formation with endogenous decay, in which agents benefit both from direct and indirect connections. In addition to forming (costly) links, agents choose actions for a coordination game that determines the level of decay of each link. We address...

We consider implementability and the welfare effects of a partial announcement policy using a model of a beauty contest where agents' actions are strategic complements and where their decisions on public information acquisition are endogenous. The following results are obtained: i) if the...

We consider demand function competition with a finite number of agents and private information. We analyze how the structure of the private information shapes the market power of each agent and the price volatility. We show that any degree of market power can arise in the unique equilibrium...

A principal seeks to persuade an agent to accept an offer of uncertain value before a deadline expires. The principal can generate information, but exerts no control over exogenous outside information. The combined effect of the deadline and outside information creates incentives for the...

We analyze demand function competition with a finite number of agents and private information. We show that the nature of the private information determines the market power of the agents and thus price and volume of equilibrium trade.We establish our results by providing a characterization of...
