I study the evolutionary stability of 'mildly responsive' behavioural rules in a bargaining game. Individuals in a population (that may be finite or be described by individuals distributed uniformly over a continuum of fixed mass) bargain with all other individuals in a pair-wise manner over a...

Industries with significant scale economies or learning-by-doing may come to be dominated by a single firm. Economists have studied how likely this is to happen, and whether it is efficient, using models where buyers are price or quantity takers, even though these industries are often also...

Traditional game theory studies strategic interactions in which the agents make rational decisions. Evolutionary game theory differs in two key respects: the focus is on large populations of individuals who interact at random rather than on small numbers of players; and individuals are assumed...

A large and growing literature on reputation in games builds on the insight that the possibility of one or more players being other than fully rational can have significant effects on equilibrium behavior. This literature leaves unexplained the presence of behavioral players in the first place,...

This paper explores the set of stochastically stable equilibria in a model in which individuals first decide to make a high or low investment, and then are matched to play a Nash demand game. If an agreement is not reached, then they are re-matched in the next period, and obtain a payoff...
