Which of the following explanations of wage differentials is not likely to be true? a. Men have more human capital than women. b. Employers in competitive markets are bigots. c. White people have more human capital than Black people. d. Men have more job experience than women.

1. **Identify the nature of the factors in a competitive labor market** In competitive markets, wages typically reflect differences in productivity-related characteristics such as human capital (education, skills, and experience). 2. **Examine human capital differences** - Option (a): Men have more human capital than women. This can lead to wage differentials because higher human capital generally commands higher wages. - Option (c): White people have more human capital than Black people. Similarly, if there is a difference in human capital, it could partially explain wage differentials. - Option (d): Men have more job experience than women. Job experience is one component of human capital, so differential experience can also explain wage differences. 3. **Analyze option (b) in the context of competitive markets** - Option (b): Employers in competitive markets are bigots. In competitive labor markets, the profit motive drives employers to hire the best candidates available. If employers were basing their decisions on prejudice rather than productivity, they would lose out in competition. Therefore, the explanation that wage differentials stem from employers’ bigotry is not consistent with the theory of competitive markets where non-productive factors are minimized. 4. **Conclusion** The explanation that is not likely to be true is: **\( \textbf{b. Employers in competitive markets are bigots.} \)**
