Estimating the Returns to Professional Certifications and Licenses in the U.S. Manufacturing Sector

Author

  • Henry Renski

Abstract

This study uses recently released Current Population Survey microdata to estimate the earnings premium associated with professional certification and licenses. The author finds that full-time manufacturing workers with a certification or license earn close to $200 more in median weekly earnings compared to those without. However, this does not account for differences in pay that are associated with worker endowments, such as education and gender. A Blinder–Oaxaca decomposition is used to distinguish the portion of the earnings gap that is attributable to the credential from the portion associated with endowments. Endowments explain 62% of the total earnings gap, meaning that the actual returns to a certification or license are closer to $70 per week. The author also finds that workers with no high school or college education receive a relatively larger increase in weekly earnings, compared to those with more advanced degrees.
