Howard (1992) argues that the Nash bargaining solution is not Nash implementable, as it does not satisfy Maskin monotonicity. His arguments can be extended to other bargaining solutions as well. However, by defining a social choice correspondence that is based on the solution rather than on its...

The note focuses on the marginal rates of substitution (MRS) in Nash’s product formula solution to bargaining and why the formula works. Two simple examples from duopoly and bilateral monopoly are used to demonstrate that the MRS's for both players are implicitly in the contract curve and the...

This paper introduces a class of endogenously proportional bargaining solutions. These solutions are inside the class of Directional solutions, which Chun and Thomson (1987) proposed to generalize (exogenously) proportional solutions of Kalai (1977). Endogenously proportional solutions are...

We consider a standard coalitional bargaining game where once a coalition forms it exits as in Okada (2011), however, instead of alternating offers, we have simultaneous payoff demands. We focus in the producer game he studies. Each player is chosen with equal probability. If that is the case,...

The Nash program is an important research agenda initiated in Nash (Econometrica 21:128-140, 1953) in order to bridge the gap between the noncooperative and cooperative counterparts of game theory. The program is thus turning sixty-seven years old, but I will argue it is not ready for...

This paper proposes a new solution concept to three-player coalitional bargaining problems. The coalitional bargaining problem is modeled as a dynamic non-cooperative game in which players make conditional or unconditional offers, coalitions continue to negotiate as long as there are gains from...

Consider a model of bargaining, in which two players, 1 and 2, share a pie of size y. The bargaining environment is described by a set a parameters λ that may affect agents' preferences over the agreement sharing, the status quo outcome, or both. The outcomes (i.e., whether an agreement is...

In this note we provide a characterization of a subclass of bargaining problems for which the Nash solution has the property of disagreement point monotonicity.While the original d-monotonicity axiom and its stronger notion, strong d-monotonicity, were introduced and discussed by Thomson [15],...

Some authors present models in which they show that the Nash bargaining solution fails to be Maskin monotonic and hence cannot be implemented in Nash equilibrium. We find this results misleading and discuss how implementability of the Nash bargaining solution can be discussed in utility space....
