We present a formal model of symmetric n-firm Cournot oligopoly with a heterogeneous population of profit optimizers and imitators. Imitators mimic the output decision of the most successful firms of the previous round a la Vega-Redondo (1997). Optimizers play myopic best response to the...

A notion of ''behavioral heterogeneity'' of a finite population of households is modelled. It is shown that the higher the degree of behavioral heterogeneity the less sensitive depends the aggregate consumption expenditure ratio upon prices.As a consequence, behavioral heterogeneity implies a...

J.M. Grandmont claims in his paper "Transformations of the Commodity Space, Behavioral Heterogeneity, and the Aggregation Problem" (1992) to model "behavioral heterogeneity". By a specific parametrization he defines a subset of all demand functions and assumes that the distribution of the...

We consider the situation in which individuals in a finite population must repeatedly choose an action yielding an uncertain payoff. Between choices, each individual may observe the performance of one other individual. We search for rules of behavior with limited memory that increase expected...

Aspiration adaptation theory (Sauermann and Selten, 1962), not available in English up to now, is a general model of non-optimizing boundedly rational behavior. The theory is presented in a more formal fashion than in the original paper. Moreover, the presentation is complemented by remarks on...

Two players bargain over the allocation of a sum of money. They are only incompletely informed about the opponent's alternative in case of conflict. The paper investigates two different experimental approaches: the spontaneous behavior of subjects in a game playing experiment and the strategies...
