I develop a model of stochastic costly signaling in the presence of exogenous imperfect information, and study whether equilibrium signaling decreases ('information substitutes') or increases ('information complements') if the accuracy of exogenous information increases. A stochastic pure costly...

Social status, or prestige, is an important motive for buying art or collectibles and for participation in charity auctions. We study a symmetric private value auction with prestige motives, in which the auction outcome is used by an outside observer to infer the bidders’ types. We elicit...

In this paper, we discuss the choice for build-operate-and-transfer (BOT) concessions when governments and firm managers do not share the same information regarding the operation characteristics of a facility. We show that larger shadow costs of public funds and larger information asymmetries...

In this paper, we consider a population of individuals who differ in two dimensions: their risk type (expected loss) and their risk aversion. We solve for the profit maximizing menu of contracts that a monopolistic insurer puts out on the market. First, we find that it is never optimal to fully...

This paper identifies the optimal two-period price sequence in the attempt for selling a good, with take-it-or-leave-it offers, when the seller faces ambiguity about the buyers' willingness to pay. If the first round fails, the seller updates its beliefs on the state of the market in accordance...

A profit maximising auctioneer can provide a public good to a group of agents. Each group member has a private value for the good being provided to the group. We investigate an auction mechanism where the auctioneer provides the good to the group, only if the sum of their bids exceeds a reserve...

A profit-maximizing auctioneer can provide a public good to at most one of a number of groups of agents. The groups may have non-empty intersections. Each group member has a private value for the good being provided to the group. We investigate an auction mechanism where the auctioneer provides...

In a differential information economy with quasi-linear utilities, monetary transfers facilitate the fulfillment of incentive compatibility constraints: the associated ex ante core is generically non-empty. How ever, we exhibit a well-behaved exchange economy in which this core is empty, even if...

We consider the effect of asymmetric information on price formation process in a financial market where private information is held by a market maker. A Byesian game is proposed in which there is price competition between two market makers with two different information partition.

Asymmetric information concerns either commodities or mutually exclusive states of the world. The notion of competitive equilibrium differs between the two cases. In particular, incentive compatibility constraints are only relevant in the case of asymmetric information concerning mutually...
