This paper studies cooperative behavior in communities with a subset of short-run players. This is done in the context of a repeated Prisoner’s Dilemma game. The introduction of a short-run player in the population breaks any equilibrium supported by symmetric pure strategies. Despite this, I...

We introduce a new class of cooperative games where the worth of a coalition depends on the behavior of other players and on the state of nature as well. We allow for coalitions to form both before and after the resolution of uncertainty, hence agreements must be stable against both types of...

Newman’s (1959, Operations Research, 7, 557–560) solution for a variant of poker with continuous hand spaces and an unlimited bet size is modified to incorporate sequential rationality.

We study the effect of communication in an experimental game where cooperation is consistent with equilibrium play if players share an understanding that cheating will be punished. Consistent with communication acting as a coordinating device, credible preplay threats to punish cheating are the...

We characterize the efficiency space of deterministic, dominant-strategy incentive compatible, individually rational and Pareto-optimal combinatorial auctions in a model with two players and k nonidentical items. We examine a model with multidimensional types, private values and quasilinear...

I present a three player dynamic network theoretic model where players are farsighted and asymmetric. Unlike the previous literature that imposes an exogenous protocol governing the order of negotiations, I allow the identity of the players who form a link in a given period to depend...

We study the effect of heterogeneous growth in demand on resource extraction. Using the Great Fish War framework of Levhari and Mirman (1980), we show that heterogeneity in demand growth has a profound effect on both cooperative and non-cooperative solutions.

This note uncovers new properties of the von Neumann-Morgenstern solution in weak tournaments and majoritarian games. We propose a new procedure for the construction of choice sets from weak tournaments, based on dynamic stability criteria. The idea is to analyze dynamic versions of the...
