The motivation of this paper comes from repeated games with incomplete information and imperfect monitoring. It concerns the existence, for any payoff function, of a particular equilibrium (called completely revealing) allowing each player to learn the state of nature. We consider thus an...

We study information transmission between informed experts and an uninformed decision-maker who only takes binary decisions. In the single expert case, we show that information transmission can only be relatively poor. Hence, even sophiscated communication games do not yield equilibria which (ex...

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 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...

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...

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 survey selected results on strategic information transmission. We distinguish between "cheap talk" and "persuasion". In the latter model, the informed player's message set depends on his type. As a benchmark, we first assume that the informed player sends a single message to the decision...
