in iran’s system of tripartite collective bargaining, does the wage-policy maker consistently react optimally to the best move made by the exchange rate-policy maker (nash-rule) or only to the state of economy (non-nash rule)?. this paper not only investigates the nature of the political game (nash rule against non-nash rule) but also estimates some structural parameters by using 2sls method an...

Using insights from the theory of projective geometry one can prove convergence of continuous fictitious play in a certain class of games. As a corollary, we obtain a kind of equilibrium selection result, whereby continuous fictitious play converges to a particular equilibrium contained in a continuum of equivalent equilibria for symmetric 4×4 zero-sum games.

We introduce best response dynamics for settings where agents' preferences are diverse. Under these dynamics, which are defined on the space of Bayesian strategies, rest points and Bayesian Nash equilibria are identical. We prove the existence and uniqueness of solution trajectories to these dynamics, and provide methods of analyzing the dynamics based on aggregation. JEL Classification: C72, C73

We show that if the set of subgame perfect equilibrium payoffs of a stage game is convexified by the introduction of public random variables, then forward induction loses all its power as an argument for refining Nash equilibrium. We establish that our argument does not depend on a convenient choice of off-equilibrium path beliefs. JEL Classification C72

An uncovered bargaining solution is a bargaining solution for which there exists a complete and strict relation (tournament) such that, for each feasible set, the bargaining solution set coincides with the uncovered set of the tournament. We provide a characterization of a class of uncovered bargaining solutions. J.E.L. codes: C72, D44.

This paper extends the connections model of network formation by allowing for players who are heterogeneous with respect to values as well as the costs of forming links. Our principal result is that centrality and short average distances between individuals are robust features of equilibrium networks.  2005 Elsevier Inc. All rights reserved. JEL classification: C72

We show that in a duopoly operating in a congested market, with a general congestion function and an arbitrary distribution of consumer disutility for congestion, there cannot exist an asymmetric Nash equilibrium. We also show that whenever an equilibrium does exist it is unique. Closed form expressions for the symmetric equilibrium prices and profits are provided. JEL Classification Numbers: C...

We construct both monotonic and non-monotonic symmetric Bayesian Nash equilibria for a two-player all-pay contest with binary types and correlated information structures. We also employ a class of parametric distributions to illustrate our equilibrium construction explicitly and to derive some comparative statics results. JEL classi…cations: C72, D44, D72, D82.

In an experimental 2x2 coordination game with two strict equilibria we observe that, in contrast to equilibrium selection theory (Harsanyi and Selten 1988), only half of the subjects choose the strategy that relates to the payoffand risk-dominant equilibrium. We propose modified risk dominance as an explanation for the observed deviations from payoff and risk dominance. JEL classification: C72,...
