Fairness in Winner-Take-All Competitions

Abstract This paper investigates fairness perceptions of extreme income inequality generated in winner-take-all competitions. Two large-scale experiments with more than 7,000 participants from the general population of the U.S. show that extreme earnings inequality is widely accepted, even when the winner only slightly outperforms the runner-up. The effect of the winning margin on inequality acceptance is modest compared to the effect of shifting the source of inequality from luck to winning by the smallest possible margin. The experimental choices are systematically associated with broader fairness attitudes and policy preferences, including support for higher taxation of top earners and redistributive economic policy.
