Winning ways: How rank-based incentives shape risk-taking decisions

Abstract

Risk-taking spurred by rank-based contest rewards can have enormous consequences, from breakthrough innovations in research competitions to hedge fund collapses engendered by risky bets aimed at raising league-table rankings. This paper provides a novel theoretical and experimental framework of rank-motivated risk-taking that both allows for complex prize structures and permits participants to make arbitrary mean-preserving changes to their random performance. As predicted by our theory, participants choose positively skewed performance under highly convex prize schedules and negatively skewed performance under concave ones. Convexifying the prize schedule or increasing competition for identical winner prizes induces riskier and more skewed performance.
