We show that under standard assumptions a Tullock contest with asymmetric information has a pure strategy Bayesian equilibrium. Moreover, two-player common-value Tullock contests in which one of the players has an information advantage have a unique equilibrium. In equilibrium both players exert...

We study how changes in the information available to the players of a symmetric common-value Tullock contest with incomplete information affect their payoffs and their incentives to exert effort. For the class of contests where players' state dependent cost of effort is multiplicative, we show...

The inefficiency of competitive markets for lemons raises fundamental questions about market performance and the role of policy intervention. We study the performance of dynamic markets, and show that when the time horizon is finite decentralized markets perform better and high quality is more...

The Arm’s Length Principle (ALP) has been broadly adopted by OECD countries to avoid the use of firm’s internal transfer pricing as a device for shifting profits into low tax jurisdictions. While the ALP does not affect market outcomes under perfect competition, we show that its adoption is...

We show that strategy-proof allocation mechanisms for economies with public goods are dictatorial -- i.e., they always select an allocation in their range that maximizes the welfare of the same single individual (the dictator). Further, strategy-proof and efficient allocation mechanisms are...

Since Littlechild (1983)'s report, price cap regulation has been regarded as an effective instrument to mitigate market power when precise information about cost and demand is available. Earle, Schmedders and Tatur (2007) establishes that the comparative static properties of price caps that hold...

Contrary to a recent literature that questions whether price caps are effective, and even sensitive, under demand uncertainty, we show that in the absence of quantity precommitment the effects of a price cap are the same whether the demand is uncertain or deterministic. Next we study the...

In markets with adverse selection, when average quality is low and frictions are small decentralized trade produces a greater surplus than predicted by the competitive model: under decentralized trade some high-quality units of the good trade whereas, due to the “lemons problem,” only...

We study the properties of mechanisms for deciding upon the provision of public goods when the feasible set is exogenously given (by financial and/or technological constraints), and individuals' preferences are represented by continuous, increasing and concave utility functions, and we establish...

We derive alternative sufficient conditions for the value of public information to be either positive or negative in a Cournot duopoly where firms technology exhibits constant returns to scale.
