Willingness to fight on: Environmental quality in dynamic contests
研究发现，高温或污染等恶劣环境会显著降低网球比赛中选手持续战斗的意愿，并基于多回合动态模型分析了环境质量如何影响竞争者的战略激励。
Abstract We show that the prevalence of prolonged tennis contests drops sharply when the ambient environment deteriorates through heat or pollution. We develop a multi‐battle dynamic model to investigate how the disutility from a protracted competition shapes agents' willingness to fight on. Our theory predicts that a poor environment amplifies the momentum of a competitor's head start. We show how model primitives including preferences for environmental amenities can be inferred from battle‐to‐battle transition probabilities. We find that heat and pollution affect incentives to compete strategically. In a contest between equally able rivals at the median prize of $15,100, the value of a head start is $130‐370 higher in a degraded environment compared with a climate‐controlled one.
