題目：No (Intention to) Profit; No Repugnance?
內容摘要：We study whether and why people feel repugnance towards harmless transactions that profit off others’ misfortune, without causing the misfortune. Examples include second-hand markets for life insurance, short selling, and prediction markets for terrorist attacks. Repugnance in these contexts can be a constraint on market efficiency. In a series of online experiments (N>2000), we find evidence of repugnance, measured using costly second- and third-party punishment, towards the party who profits from others' negative (or even positive) outcome that is merely determined by luck. Intentions play a role only for second- but not third-party punishment. Overall, repugnance is mainly outcome-based: people dislike profit-making that occurs as a result of others’ (mis)fortune.
