Nous étudions l'impact des participations au capital sur les enchères à valeurs privées indépendantes. Le revenu de l'enchère décroît lorsque les acheteurs ont des participations croisées et croît lorsqu'ils détiennent une partie du capital du vendeur. Dans tous les cas de...

When an incumbent firm is in charge of a distribution network, it accumulates information on the state of the network. This `common value' information creates a winner's curse during auctions for renewing the concession. The municipality contracting out the provision of the service trades off...

We propose a semi-cooperative game theoretic approach to check whether a given coalition is stable in a Bayesian game with independent private values. The ex ante expected utilities of coalitions, at an incentive compatible (noncooperative) coalitional equilibrium, describe a (cooperative)...

In a commonvalueauction in which the information partitions of the bidders are connected, all rings are core-stable. More precisely, the ex ante expected utilities of rings, at the (noncooperative) sophisticated equilibrium proposed by Einy et al. [Einy, E., Haimanko, O., Orzach, R., Sela, A.,...

We consider a setting in which two potential buyers, one with a prior toehold and one without, compete in a takeover modeled as an ascending auction with participating costs. The toeholder is more aggressive during the takeover process because she is also a seller of her own shares. The...

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 study the impact of crossholdings on the efficiency of the standard auction formats. The ascending auction is not equivalent to the second-price auction. In a class of examples, the ascending auction is the only efficient standard auction format.

We evaluate the impact of three auction mechanisms – the Becker–DeGroot–Marschak (BDM) mechanism, the second-price auction (SPA), and the random nth-price auction (NPA) – in the measurement of private willingness-to-pay and willingness-to-accept for a pure public good. Our results show...

Nous considérons la vente aux enchères sous pli scellé au second prix d'un objet que chaque acquéreur potentiel évalue de manière « privée et indépendante ». Nous montrons que l'optimum ex ante d'un cartel, sous contraintes d'incitation et d'équilibre ex post des transferts, coïncide...

This paper examines the relationship between gas spot prices at the Zeebrugge market, one-month ahead Brent prices and temperatures over the period 2000–2005. A cointegration analysis is carried out and it is discovered that a cointegration relationship exists between the three series. To take...
