The present project investigates gender differences in individual-level pay information disclosure (i.e., discussing pay with coworkers) across three studies. The first study finds that women are less likely than men to discuss their pay with their co-workers. The results of the subsequent studies show that, controlling for factors such as individual income, industry, and firm compensation policies, women exhibit a preference for less pay information sharing than their male counterparts. These findings could have important implications for the design of gender pay equity initiatives and laws that promote the free exchange of pay information among employees.
