IZA DP No. 14551: Non-Base Compensation and the Gender Pay Gap
This paper investigates whether non-base compensation contributes to the gender pay gap. In wage decompositions, we find that lower bonus payments to women explain about 10% of the gap at the mean and at different quantiles of the unconditional wage distribution whereas the lower prevalence of shift premia and overtime pay among women is unimportant. Among managers, the contribution of bonuses to the mean gap more than doubles and is steadily rising as one moves up the wage distribution. Our findings suggest that gender differences in bonuses are an important contributor to the gender pay gap, particularly in top jobs.
