Working under pressure: Evidence from the impacts of soccer fans on players’ performance

In this paper we study how pressure affects individual’s behavior. For this purpose we use sports data, where the attendance is a proxy for pressure, to investigate if the number of fans in the stadium affects the performance of the players. We overcome the reverse causality problem by proposing an instrument variable: a promotion in Brazil during which low cost tickets were assigned to random soccer matches. In contrast to previous literature, our results suggest that pressure does not significantly affect players’ behavior.
