In this paper, a human capital model is used to investigate the effects of occupational licensing and occupational certification on the wage rates of individual women. When we analyzed micro data available from the National Longitudinal Surveys of mature and young women, we found that licensed women earn about 20 percent more per hour after controlling for personal characteristics, regional location, human capital factors, and occupational category. No statistically significant premium was found for certified women.
