textabstractHow are top earners affected by productivity shocks? We address this question using a unique longitudinal data set on the universe of professional football players in the Italian Serie A, representing 20% of top earners in Italy. We use traumatic injuries and adopt an IV strategy to provide causal estimates of the impact of productivity shocks on several labour market outcomes. We find that a 30-day injury substantially affects the probability of contract renegotiation and reduces net wages by around 12%. We show that this large penalty is due to employer's precautionary motives rather than to shock-induced reduction in current player's performance.

高收入者的生产力冲击和劳动力市场结果：来自意大利甲级联赛的证据

textabstract 高收入者如何受到生产力冲击的影响？我们使用一个独特的纵向数据集来解决这个问题，该数据集是关于意大利意甲职业足球运动员的，占意大利最高收入球员的 20%。我们使用外伤并采用 IV 策略来提供生产力冲击对几种劳动力市场结果的影响的因果估计。我们发现 30 天的工伤会显着影响合同重新谈判的可能性，并使净工资减少约 12%。我们表明，这一巨额罚款是由于雇主的预防动机，而不是由于休克导致当前球员表现下降。
