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 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)...

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 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 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.

This research explores the effect of the introduction of online reverse auctions (ORAs) on interorganizational trust between buyers and suppliers in the retail industry. Building upon the notion of the spirit of the technology and the organizing vision, we shed light on the "equivoque" nature of...
