Abstract：
We show that the prevalence of prolonged contests in professional tennis drops sharply when the ambient environment deteriorates through heat or pollution. We develop a dynamic model of multi-battle competition to investigate how the disutility from a protracted competition shapes agents' willingness to fight on. Our theory predicts that a deteriorating environment enhances the momentum of a competitor's head start. We show how structural model primitives including the demand for environmental amenities can be inferred from battle-to-battle transition probabilities. In our specific setting of high-profile tennis matches played in Australia and China, an agent's disutility from an additional battle in either hot weather or polluted air runs into the thousands of dollars relative to cooler and cleaner environments. Overall, we provide clean evidence that heat and pollution affect individuals' willingness to compete strategically.
