I study an evolutionary model of equilibrium selection in supermodular games where players are involved in simultaneous play. This is taken to refer to a context, in contrast with most evolutionary literature, where players' objective is to have their actions match a certain statistic of the...

We apply the dynamic stochastic framework proposed by recent evolutionary literature to the class of strict supermodular games when two simple behavior rules coexist in the population, imitation and myopic optimization.

This paper deals with a simple, Keynesian growth model. The main issue is whether Nash bargaining about wages may help to avoid cycles. Our result comes somewhat in the negative: Cycles may still persist. Their existence or emergence is related to violent investment behavior near the long-run,...

The main objects below are transferable-utility games in which each agent faces an optimization problem, briefly called production planning, constrained by his resource endowment. Coalitions can pool members's resources. Such production games are here extended to accomodate uncertainty about...

We model repeated play of noncooperative stage games in terms of approximate gradient steps. That simple format require little information and no optimization. Moreover, it allows players to evaluate marginal cost or profit inexactly and to move with different velocities. Uncertainty can also be...

Owners of stochastic assets can pool their endowments to smoothen and insure individual payoffs across outcomes and time. We explore, in such a setting, how contingent shadow prices on aggregate resources can be used for three purposes: first, to design mutual contracts for risk averse agents;...

We apply the stochastic evolutionary approach of equilibrium selection to macroeconomic models in which a complementarity at the macro level is present. These models often exhibit multile Pareto-ranked Nash equilibria , and the best response-correspondence of an individual increases with a...

A two-agent model for the exploitation of the Arcto-Norwegian cod stock is developed to investigate the economic benefits that can be realized from resources , and the effect of exploitation on stock sustainability under cooperation and non-cooperation.

This paper develops a bioeconomic model for two Barents Sea fisheries that attempts to capture the predator-prey relationships between cod and capelin, the two main species in the habitat. The aim is to analyze joint (cooperative) versus separate (noncooperative) management of this predator-prey...

So-called potential functions are important, prominent, and common to many diverses fields, including optimization, dynamic processes, and physics. Monderer and Shapley have recently added a class of noncooperative games to that list. We extend their notion and consider repeated play of games...
