Inequality and Competitive Effort: The Roles of Asymmetric Resources, Opportunity and Outcomes

We study the effects of different sources of inequality in a commonplace economic interaction: competition. We investigate how individuals react to different types of inequality in experimental two-player Tullock contests where contestants expend resources to win a prize. We study three different sources of inequality: resources, abilities and possible outcomes. We find that overall competitive effort is greater in the presence of inequality in abilities than other inequalities. Unlike other forms, inequality in abilities elicits a very aggressive reaction from disadvantaged players relative to their advantaged opponents. The Quantal Response Equilibrium (QRE) suggests that financial incentives are less salient in the presence of a biased contest procedure.
