Abstract

This paper empirically identifies the spillover effects of superstars on peers by exploiting the timing variations of star arrivals and star injuries in the Chinese Super League (CSL). We find that peer performances increase steadily with superstar exposure time, implying positive dynamic spillover effects. We show evidence that the spillovers occur through peers’ skill dimension that is complementary to the stars’. We also find that stars with higher market value exert greater spillovers to peers and, in contrast, non-star foreign players generate no spillovers.
