We study a competitive market for a homogeneous good, in which the only uncertainty concerns the number of identical sellers, who are sampled by a finite Poisson process from a continuum of potential participants. It is shown that, in equilibrium, there is price dispersion. Specifically, prices...

Increasing evidence shows that ICT investment improves firm performance. Among the many explanations on why ICT contributed to labor productivity surge since 1990, this is the most promising one. It is thus necessary to take the firm as an information processing organization, putting it in...

This paper studies the effects on insurance premiums and consumer welfare when commissions to insurance agencies exist and are used strategically to sell insurance policies. The opportunistic behavior of agency insurers that sell the policy paying the highest commission is considered. Different...

n overview of the landmark contributions of Robert J. Aumann, winner of the 2005 Nobel Memorial Prize in Economic Sciences.

We develop tests for common values at first-price sealed-bid auctions. Our tests are nonparametric, require observations only of the bids submitted at each auction, and are based on the fact that the "winner's curse" arises only in common values auctions. The tests build on recently developed...

A standard “solution” offered to the deleterious effects of all-out price competition is for firms to engage in differentiation strategies. This solution, however, depends critically on the inability of rivals to imitate a successful differentiation strategy. With imitation, we show how...

This paper examines the effect of demand uncertainty on the properties of the first period contract between a lender and the incumbent, when there is a threat of entry. The main findings are that unlike the cost uncertainty case, entry has no effect on the incumbent's incentives and it leads the...

This paper makes three contributions: (1) A competitive revelation principle for contracting games in which several principals compete for one privately informed agent. Specifically, given any profile of incentive compatible indirect contracting mechanisms, there exists an incentive compatible...

Can software piracy be profitable for a software editor? We tackle this issue in a simple model where software is an experience good and where the potential users can choose to adopt or pirate software or to delay their adoption. In that context, we show that a moderate piracy can be profitable...

We examine algorithmic trades (AT) and their role in the price discovery process in the 30 DAX stocks on the Deutsche Boerse. AT liquidity demand represents 52% of volume and AT supplies liquidity on 50% of volume. AT act strategically by monitoring the market for liquidity and deviations of...
