Managerial Incentives and Investment Policy in Family Firms: Evidence from a Structural Analysis
研究发现，CEO期权组合的波动率敏感性（vega）较低是导致活跃家族企业减少高风险研发投资的重要原因，而被动家族企业则更倾向于研发和并购投资。
This paper provides evidence that CEO incentive pay mediates the effect of family preferences on corporate investment policy. Our study focuses on the option portfolio volatility sensitivity vega, which motivates the risk-taking behavior of undiversified managers. After controlling for factors that affect incentive pay and investment policy simultaneously, we find that one-third of underinvestment in riskier R&D projects in active family firms can be attributed to a significantly lower vega. Passive family firms allocate more capital to R&D as opposed to active family firms, and are more active in M&A deal making. In contrast to many prior studies, pay incentives and families are not associated with capital expenditures. Overall, our empirical results suggest that CEO pay incentives induce investment policy contingent on firm risk. Family CEO incentive pay manifests the family preference for lower risk, especially in firms with higher firm risk. Nonetheless, after replacing family CEOs with outside professionals, investments in both R&D and M&A increase, which is consistent with the family preference for extended investment horizons. Interestingly, such a preference seems not to be manifested in incentive pay.
