We model academic competition as a game in which researchers ¯ght for priority. Researchers privately experience breakthroughs and decide how long to let their ideas mature before making them public, thereby establishing priority. In a two-researcher, symmetric environment, the resulting...

We consider a preemption game with two potential competitors who come into play at some random secret times. The presence of a competitor is revealed to a player only when the former moves, which terminates the game. We show that all perfect Bayesian equilibria give rise to the same distribution...

We show that sellers may earn reputation for their \ability" to deliver high quality goods on average by honestly announcing the realised quality of items for sale every period. As the expected revenue stream from continuing with honest communication increases with their ability, high ability...

We show that the standard analysis of vertical relationships transposes directly to investment timing. Thus, when a firm undertaking a project requires an outside supplier (e.g. an equipment manufacturer) to provide it with a discrete input, and if the supplier has market power, investment...

We model investments in capacity in a homogeneous product duopoly facing uncertain demand growth. Capacity building is achieved through adding production units that are durable and lumpy and whose cost is irreversible. There is no exogenous order of moves, no first-mover or second-mover...

We develop a model where a genetic test reveals whether an individual has a low or high probability of developing a disease. A costly prevention effort allows high-risk agents to decrease this probability. Agents are not obliged to take the test, but must disclose its results to insurers, and...

This paper addresses the issue of price signaling in a model of vertical relationship between a manufacturer and a retailer who share the same information about quality, unlike consumers who do not observe it a priori. We show that delegating the price setting task to a retailer and controlling...

The paper revisits and qualifies existing insights on security design. A rich literature argues that tranching creates debt-like instruments that are robust to adverse selection or discourage wasteful information acquisition. Yet, for a given information structure, while tranching confines and...

Derivatives activity, motivated by risk-sharing, can breed risk taking. Bad news about the risk of the asset underlying the derivative increases the expected liability of a protection seller and undermines her risk prevention incentives. This limits risk-sharing, and may create endogenous...
