In repeated-round auction mechanisms with endogenous market-clearing prices, i.e. when prices depend on submitted bids, the assumption of independent private values that underlines the property of incentive-compatibility is to be brought into question; even if these mechanisms provide active...

We consider an auction setting, in a symmetric information framework, in which bidders, even if they fail to obtain the good, care about the price paid by the winner. We prove that the outcome of the first-price auction is not affected by identity-independent price externalities, while the...

We show that jump bids can be used by a bidder to create a winner's curse and preserve an informational advantage that would otherwise disappear in the course of an open ascending auction. The eect of the winner's curse is to create allocative distortions and reduce the seller's expected...

This paper examines how shareholdings affect auctions' revenue and efficiency with independent private values. Two types of shareholdings are analyzed: Vertical (resp: horizontal) toeholds cover situations in which bidders own a fraction of the seller's profit (resp: a share of their...

We analyze the privatization of highway firms, focusing both on the sale of the shares of these firms and the tenders organized by the highway firms for the maintenance of the highways network. If a public works firm buys shares of a highway firm, tenders become inefficient and the revenue of...

We analyze the rationale for hiding information in open auction formats. In particular, we focus on the incentives for a bidder to call a price higher than the highest standing one in order to prevent the remaining active bidders from aggregating more accurate information that could be gathered...

Ce rapport présente le bilan de la première phase du projet « Acquisitions Publiques par Enchères Électroniques Renversées et Ouvertes » financé en partie par le Conseil du Trésor du Gouvernement du Québec. Il y est fait état des principales propositions de réforme aux procédures...

We conduct an experiment to test whether probability misperception may be a possible alternative to risk aversion to explain overbidding in independent first-price private-values auctions. The experimental outcomes indicate that subjects underestimate their probability of winning the auction,...
