The Unfairness Trap: A Key Missing Factor in the Economic Theory of Discrimination

corporate performance, and individual compensation from a nationally representative sample of Japanese firms in the 2000s. We find that increases in the ratio of female executives, the presence of at least one female executive, and the presence of at least one female section chief are associated with increases in corporate profitability in the manufacturing sector. These results are not specific to Japanese firms only: North American multinationals operating in Japan also experience outsized benefits from hiring and promoting female managers. The results are robust to controlling for time effects and company fixed effects and the time-varying use of temporary and part-time employees. A very small part of the competitive benefit of employing female managers does flow from compensation savings, but a far larger part arises from direct productivity increases. Prior economic theory on discrimination is largely silent on the impact of discrimination on worker productivity and hence cannot explain these findings. We extend the theory by modeling this relationship, and test it empirically by showing that due to possible social comparison costs, only companies whose compensation of female talent compares well with compensation in the local labor market for similarly qualified males will see a significant performance benefit.
