Directing the Labor Market: Shared Directors and Employee Flows

Using résumé data on over 20 million U.S. workers, we find that the flow of employees between a pair of firms sharply drops by about 20% during periods in which the firms share a board director. This relationship is stronger in settings where firms have greater potential gains from limiting worker mobility and is most pronounced for higher-skilled employees. Moreover, we find more connected firms have lower rates of internal promotion and no improvements in employee satisfaction. The evidence is consistent with shared directors serving as a mechanism for labor market coordination. (JEL G34, G38, J42, J62, J08, K21, K31, M50)
