Cognitive Performance in Remote Work: Evidence from Professional Chess
利用疫情期间国际象棋比赛从线下转为线上的自然实验，借助人工智能引擎评估棋步质量，发现远程比赛导致认知表现显著下降，但随时间推移有所适应。
Abstract During the COVID-19 pandemic, traditional (offline) chess tournaments were prohibited and instead held online. We exploit this unique setting to assess the impact of remote work policies on the cognitive performance of individuals. Using the artificial intelligence embodied in a powerful chess engine to assess the quality of chess moves and associated errors, we find a statistically and economically significant decrease in performance when an individual competes remotely versus offline in a face-to-face setting. The effect size decreases over time, suggesting an adaptation to the new remote setting.
