Outline of Final Research Achievements

We aimed to reveal how to improve team productivity, focusing on the peer effect. This study examined the peer effects of newcomer on the performance of existing members of teams, based on comparing the performances of swimming team members before and after the arrival of a newcomer. The identification strategy was similar to a natural experimental setting. This study found that the performance of an existing member of a team improves when a newcomer joins the team and that this effect is larger when the newcomer is a superior to the original team members.

Academic Significance and Societal Importance of the Research Achievements

ピア効果についてはまだ明らかになっていない部分が多く、影響の大きさや方向、相手の属性や相手との関係性などについてなど、効果の詳細がはっきりしていない。特に、ピア効果を実証可能なデータの制約上、長期的な影響はほとんど研究されていないといえる。本研究課題では競泳データを用いることで、同一個人のパフォーマンスを最大7年間追跡することが可能であった。
