A hostage with respect to an action of a player is defined here to be an amount ofpayoff that will be placed in the opponent's possession if the player takes the action. Whereas the only Nash equilibrium for a prisoner's dilemma game is mutual defection, it is shown that there are at most two...

We show in a differential game of a differentiated product doupoly model of price competition with costly production adjustment that when firms are symmetric the leadership attempt by each firm turns into Stackelberg price warfare yielding a (MArkov perfect) steady state outcome more competitive...

In his work on signaling, Spence proposed a dynamic model of a market in which a buyer revises prices in light of experience and in which sellers, with private information about their type, choose utility-maximizing signals given these prices. We follows Spence's suggestion of introducing...

This paper introduces E-capacities as a representation of beliefs which incorporates objective information about the probability of events. It can be shown that the Choquet integral of an E-capacity is the Ellsberg representation. The paper further explores properties of this representation of...

We make three contributions to the theory of contracting under asymmetric information. First, we establish a competitive revelation principle for contracting games in which several principals compete for one privately informed agent. In particular, we show that given any profile of incentive...

We consider the problem of bargaining over the disclosure of interim research knowledge, between two participants in a R & D race or contest, for an ultimate, patentable invention. Licensing fee schedules, as fuctions of the "amount of knowledge" disclosed by the leading to the lagging agent,...

If a solution (on a closed family of games) satisfies dummy axiom (DUM) and independance of irrelevant strategies (IIS) then it also satisfies consistency (CONS) (proposition 2.21, Peleg and Tijs, 1996). The converse of this proposition is not true: CONS implies neither DUM nor IIS as shown in...

In this paper we prove that for generic (non cooperative) voting games under plurality rule an equilibrium that induces a mixed distribution over the outcomes (i.e. with two or more candidates elected with positive probability) is isolated. From that we deduce also that the set of equilibrium...

I propose how to model memory loss of knowledge.
