Job market paper: Identifying teamwork in professional tennis

 

Teamwork is a first order concern for any organization bigger than a single individual. This paper provides a novel identification approach to measure value-added from teamwork net of solitary work. Holding constant the assigned task, compare a worker’s contribution to output when acting alone versus when working in a team. The discrepancy between the two is that worker’s value-added due to teamwork, net of solitary work. The current application to professional tennis finds that over one-fifth of output variation is explained by team value-added. Players match assortatively along both own skill and team skill dimensions, but do not sort interdimensionally. Additionally, a specification test rejects the log additive production function, but finds this departure economically insignificant to decomposing output.
