The paper compares different auction formats for sale of a single patented innovation for budget constrained bidders. This unit decreases the marginal cost of production in the aftermarket for its owner by an amount which depends on the money invested on the development of this technology. As...

Auction mechanisms commonly used in practice for awarding infrastructure concession contracts induce a bias towards the selection of concessionaires who are optimistic about demand, but are not necessarily cost-efficient. This helps to explain the frequent renegotiation of concessions observed...

This paper presents a new mechanism for awarding tolled-highways, based on the variable-term concept proposed by Engel et al (1997). These authors claim that a mechanism based on bids for least-present-value of revenue (LPVR) eliminates the risk of demand and simplifies renegotiations. However,...

We examine the relative performances of reverse auctions and request for quotes in a simple commodity environment. Enterprises embarking on a reverse auction initiative often start with their commodity purchases. We conduct laboratory experiments and find that this is a poor starting point. Both...

In the market game presented here, sellers offer trade mechanisms to buyers, and buyers randomize over the sellers they visit. The distribution of buyers across sellers is endogenous and depends on all of the transaction opportunities existing in the market. Sellers choose from a broad class of...

I introduce a property of player's valuations that ensures the existence of an ex post efficient equilibrium in asymmetric English auctions. The use of this property has the advantage of yielding an ex post efficient equilibrium without assuming differentiability of valuations or that signals...

Estimating bidders’ risk aversion in auctions is a challeging problem because of identification issues. This paper takes advantage of bidding data from two auction designs to identify nonparametrically the bidders’ utility function within a private value framework. In particular, ascending...

Private sector participation in infrastructure projects traditionally financed by governments (roads, airports, seaports) is increasing around the world. This paper describes how a toll road concession works. It discusses how the usual mechanism, based on a concession contract with a...

We analyze the optimal auction of multiple non-identical objects when buyers are risk averse. We show that the auction formats that yield the maximum revenue in the risk neutral case are no longer optimal. In particular, selling the goods independently does not maximize the seller's revenue. We...

This paper estimates the value of superstitions by studying the auctions of vehicle license plates. We show that the value of superstitions is economically significant, which in turn justifies their persistence in human civilization. We also show that such a value, though based inherently on...
