AbstractWe study how agents adapt their behaviour to variations of incentives in dynamic contests. We investigate a real dynamic contest with large stakes: professional tennis matches. Situations in which balls bounce very close to the court's lines are used as the setting of a quasi-experiment providing random variations in winning probability. We find evidence of a momentum effect for men whereby winning a point has a positive causal impact on the probability to win the next one. This behaviour is compatible with a reaction to the asymmetry of incentives between leaders and followers. We do not find momentum for women.

In most collective actions, individuals' incentives are not perfectly aligned with the goals of the group/team they are part of. We investigate how individual specific incentives affect both individuals and team leaders' strategies in a natural setting. We use a discontinuity in individual rewards in batsmen scoring in cricket to identify the causal effect of such incentives on behavior. We find that batsmen react to the presence of individual-specific incentives by adopting strategies that may be suboptimal at the team level. More surprisingly, we also find that team captains react to these individual incentives by adopting suboptimal strategies at the team level, which may bring large benefits to the individual players. These results suggest a complex interplay of individual and team incentives which we conjecture may arise in repeated team interactions.
