In a market where sellers compete by posting trading mechanisms, we allow for a general search technology and show that its features crucially affect the equilibrium mechanism. Price posting prevails when meetings are rival, i.e., when a meeting by one buyer reduces another buyer's meeting...

Current models of conservation auctions do not permit for the presence of environmental externalities and synergies between bidders. Yet, conservation auctions are usually set up for the very purpose of addressing problems associated with environmental externalities. Clearly, our models do not...

This paper considers the problem of identification and estimation in the firstprice multi-unit auction. It is motivated by the auctions of bus routes held in London where bidders submit bids on combinations of routes as well as on individual routes. We show that submitting a combination bid...

We look at the links between the Digit Ratio - the ratio of the length of the index finger to the length of the ring finger – for both right and left hands, and giving in a Dictator Game. Unlike previous studies with exclusively Caucasian subjects, we recruited a large, ethnically diverse...

This paper presents a game theoretic analysis of the generalized second-price auction that the company Overture operated in 2004 to sell sponsored search listings on search engines. We construct a model that embodies few prior assumptions about parameters, and we present results that indicate...

This paper proposes an approach to proving nonparametric identification for distributions of bidders' values in asymmetric second-price auctions. I consider the case when bidders have independent private values and the only available data pertain to the winner's identity and the transaction...

This paper studies a dynamic model of a financial market with N strategic agents. Agents receive random stock endowments at each period and trade to share dividend risk. Endowments are the only private information in the model. We find that agents trade slowly even when the time between trades...

The restructuring of a bankrupt company often entails the sale of such company. This paper suggests a way to sell the company that maximizes the creditors’ proceeds. The key to this proposal is the option left to the creditors to retain a fraction of the shares of the company. Indeed, by...

This paper develops a model of endogenous product selection by firms. The theory is motivated by new evidence we present on the importance of product switching by U.S. manufacturers. Two-thirds of continuing firms change their product mix every five years, and product switches involve more than...

We estimate the impacts of an energy tax – the Climate Change Levy (CCL) – on the manufacturing sector using panel data from the UK production census. Our identification strategy builds on the comparison of trends in outcomes between plants subject to the CCL and plants that were granted an...
