The Suppes-Sen dominance relation is a weak and widely accepted criterion of distributive justice. We propose its application to Nash bargaining theory. The Nash Bargaining Solution (NBS) is characterised by replacing the contriversial Independence of Irrelevant Alternatives axiom with an axiom...

Many local public goods are provided by coalitions and some of them have network effects. Namely, people prefer to consume a public good in a coalition with more members. This paper adopts the Drèze and Greenberg (1980) type utility function where players have preferences over goods as well as...

The literature on time-inconsistent preferences introduced naive, partially naive and sophisticated as types of agents that represent different levels of unawareness of agents' self-control problems. This paper incorporates time-inconsistent players in a sequential bargaining model. We first...

In this paper we address the question of collusion in mechanisms under asymmetric information. We develop a methodology to analyze collusion as an informed principal problem. First, if collusion occurs after the agents accept or reject the principal's offer; the dominant-strategy implementation...

The winner of a battle for a throne can either execute or spare the loser; if the loser is spared, he contends the throne in the next period. Executing the losing contender gives the winner an additional quiet period, but then his life is at risk if he loses to some future contender. The...

In this note we show that the equilibrium characterized by Biais, Martimort and Rochet (Econometrica, 78, 2000) could have been characterized by using direct mechanisms.

[Forthcoming, American Economic Review.] We model a War of Attrition with N+K firms competing for N prizes. If firms must pay their full costs until the whole game ends, even after dropping out themselves (as in a standard-setting context), each firm's exit time is independent both of K and of...

Several authors have indicated a contradiction between consistent aggregation of subjective beliefs and tastes, and a Pareto condition. We argue that the Pareto condition that implies the contradiction is not compelling. Society should not necessarily endorse a unanimous choice when it is based...

A typical assumption of the standard alternating-offers model under risk is that the breakdown event means a complete and irrevocable halt in negotiations. We reinterpret the meaning of breakdown as the imposition to finish negotiations immediately. Specifically, after breakdown the last offer...
