Social Exchange and the Effects of Employee Stock Options

The authors assert that broad-based stock options create a social exchange relationship between the employer and employees, leading to higher individual job performance in the next period. They compare this social exchange hypothesis to the more typical incentive-based explanation for stock options, which is that holding options generates financial incentives for better individual job performance in the current period. Findings show that significant and meaningful relationships are associated with social exchange effects and that these are both independent of incentive effects and arguably greater than those for the incentive effects. The authors use non-parametric and parametric fixed effects models, other controls for sample heterogeneity, and alternative specifications to address possible concerns about identification and endogeneity. These results extend empirical studies of social exchange relationships to common workplace practices. They also raise the possibility that some of the performance effects attributed to incentives in other studies may actually be attributable to social exchange effects.
