Managing the family firm: evidence from CEOs at work

We present evidence on the labor supply of CEOs, and on whether family and professional CEOs di↵er on this dimension. We do so through a new survey instrument that allows us to codify CEOs’ diaries in a detailed and comparable fashion, and to build a bottom-up measure of CEO labor supply. The comparison of 1,114 family and professional CEOs reveals that family CEOs work 9% fewer hours relative to professional CEOs. Hours worked are positively correlated with firm performance, and di↵erences between family and non-family CEOs account for approximately 18% of the performance gap between family and non-family firms. We investigate the sources of the di↵erences in CEO labor supply across governance types by exploiting firm and industry heterogeneity, and quasi-exogenous meteorological and sport events. The evidence suggests that family CEOs value–or can pursue–leisure activities relatively more than professional CEOs.
