We present and study a three-stage model of a decentralized distribution system consisting of n retailers, each of whom faces a stochastic demand for an identical product. In the first stage, before the demand is realized, each retailer independently orders her initial inventory. In the second...

We advance an image of coopetition as a synthesis of the two alternative paradigms developed in the literature about the nature of the interdependences among firms; i.e., the competitive paradigm versus the cooperative paradigm. The competitive paradigm postulates divergent interest-based...

This paper analyzes three-party negotiations in the presence of externalities, deriving a close form solution for the stationary subgame perfect Nash equilibrium of a standard non-cooperative bargaining model. Players' values are monotonically increasing (or decreasing) in the amount of negative...

This paper proposes a model for multilateral contracting, where contracts are written and renegotiated over time, and where contracts may impose externalities on other agents. The paper derives several properties of the Markov perfect equilibria of the infinite state-space contracting model....

This paper provides a noncooperative approach to core stability in an economy with incomplete information. The analysis covers general exchange economies, although our tightest results hold when effective coalitions consist of at most two players, as in matching. We study the perfect Bayesian...

We revisit the classical object reallocation problem under strict preferences. When attention is constrained to the set of Pareto-efficient rules, it is known that TTC is the only rule that is strategyproof and individually-rational. We hence relax this constraint and consider pair-efficiency. A...

Playing a bargaining game, the players with non-conforming expectations were trying to enlarge their share of a sugar-pie. The first player, who was not very keen on sweets, placed an emphasis on quality. In contrast, for the second player, all sweet options, whatever they might be, were open....

We study assignment problems with externalities where agents have expectations about the reactions of other agents to group deviations. We present notions of core consistent with such expectations and identify the largest and smallest cores. We restrict the domain of preferences to study the...

The most successful human societies are those that have found better ways to promote cooperative behaviour. Yet, cooperation is individually costly and, therefore, it often breaks down, leading to enormous social costs. In this article, I review the literature on the mechanisms and interventions...

A core allocation of a complete information economy can be characterized as one that would not be unanimously rejected in favor of another feasible alternative by any coalition. We use this test of coalitional voting in an incomplete information environment to formalize a notion of resilience....
