We investigate the relationship between collusive behavior in Bertrand oligopoly experiments and subject heterogeneity in risk preferences. We find that risk aversion is positively associated with tacit collusion when the goods are complements, but find no evidence of collusive behavior when the...

We experimentally test a rent seeking model under five levels of competition. At one extreme, a subject’s probability of winning a prize is equal to her share of the total expenditures. At lower levels of competition, a subject’s probability of winning is affected more by her own...

We study the effect of demand structure on the ability of subjects to tacitly collude on prices by considering Bertrand substitutes and Bertrand complements. We find evidence of collusion in the complements treatment, but no such evidence in the substitutes treatment. This finding is somewhat in...

Several non-experimental studies report that income inequality and other forms of population-based heterogeneity reduce levels of trust in society. However, recent work by Glaeser et al. (2000) calls into question the reliability of widely used survey-based measures of trust. Specifically,...

A popular perception among the American electorate is that Democrats and liberals are more caring and kind-hearted than Republicans and conservatives. This stems in part from the consistent finding in opinion surveys that left-leaning individuals tend to support increased public spending on...
