Terms of use: Documents in AbstractWe assess the predictive power of a model of other-regarding preferences-inequality aversion-using a within-subjects design. We run four different experiments (ultimatum game, dictator game, sequential-move prisoners' dilemma and public-good game) with the same sample of subjects. We elicit two parameters of inequality aversion to test several hypotheses across games. We find that within-subject tests can differ markedly from aggregate-level analyses. Inequality-aversion has predictive power at the aggregate level but performs less well at the individual level. The model seems to capture various behavioral motives in different games but the correlation of these motives is low within subjects.JEL Classification numbers: C72, C91.

Abstract In this paper we investigate how the competitiveness of Cournot markets varies with the number of …rms in an industry. We review previous Cournot experiments in the literature. Additionally, we conduct a new series of experiments studying oligopolies with two, three, four, and …ve …rms in a uni…ed frame. With two …rms we …nd some collusion. Three-…rm oligopolies tend to produce outputs at the Nash level. Markets with four or …ve …rms are never collusive and typically settle at or above the Cournot outcome. Some of those markets are actually quite competitive with outputs close to the Walrasian outcome.
