This paper reports an experiment conducted to examine the effects of changing the form of strategic interactions (Bertrand or Cournot), and changing underlying information conditions on the usefulness of the ‘ALM,’ a merger simulation device used by the U.S. Department of Justice. The experiment consists of twenty 60-period quadropolies. After period 40 a merger is induced. Behaviorally, Courno...

The paper presents simulation of two classic duopoly games, those of Cournot and Bertrand. The simulation is done with a very simple Discrete Event Simulation system, aGPSS, developed for economics students. With the Cournot model one can study under which conditions the Cournot solution will be obtained even if the parties lack knowledge about demand and costs. The Bertrand model, with stochas...

This paper presents an oligopoly model of multiproduct firms in which firms are endowed with possibly different marginal cost and product quality, and choose product ranges before product market competition. Consistent with empirical evidence on a positive relationship between firm size and product diversification, the analysis suggests that firms with higher quality-cost margins typically have...

We study the evolutionary selection of conjectures in duopoly games when players have other regarding preferences, i.e. preferences over payoff distributions. In both the Cournot and Bertrand duopoly games, the consistent conjectures are independent of other regarding preferences. Both duopoly games have evolutionarily stable conjectures that depend on other regarding preferences but that do no...
