Using a unique pan-European dataset, we rely on two alternative measures of over-education and control stepwise for four groups of covariates in order to interpret the over-education wage penalty in light of theoretical models. Firstly, it appears that a significant fraction (i.e. between 1/5 and 1/3) of PhD holders in Europe are genuinely…

In light of growing difficulties for schools to attract teachers in science, technology, engineering, and mathematics (STEM) fields and the continued discussions surrounding the unionization of education, this paper examines the effect of collective bargaining (CB) laws on the salary of teachers with a STEM degree. To isolate the effect of…

This paper evaluates the impact of education on inequality using the recentered influence function regression and standard inequality measures. Results indicate that between 2005 and 2010, the returns to education declined from the 10th to the 50th percentiles, but increased at the upper tail of the distribution. Inequality is lower in the…

This paper estimates returns to education during a period of sharp wage cuts in Greece, considering both the endogenous nature of education and women's self-selection. Findings suggest that dramatic wage declines were followed by sharp decreases in returns to education, while the documented convergence of returns between genders is an added…

This study examines the return to education in South Korea by comparing metropolitan areas with non-metropolitan areas. It utilizes the Korean Labor and Income Panel Study from 2018 and 2019 for analysis, alongside the Mincer equation. The findings indicate that female workers have a higher return to education compared to male workers. The Oaxaca…

This study measures college quality by the amount by which the college adds to the salary of its students above what the median market value would be for the same majors and student quality. Commonly used national rankings of colleges such as U.S. News and World Report or Forbes are heavily biased by a college's average salaries and the quality of…

We present new estimates of the internal rate of return to early childhood education. Utilizing the nationwide expansion of preschool education in Japan between 1960 and 1980, we initially assess the impact of preschool attendance on high school graduation and college enrollment for men. Subsequently, we compute the social rate of return to…

The question of why postsecondary institutions produce different labor market outcomes is difficult to answer due to unobserved student characteristics. Here, I leverage students' geographic proximity to three classifications of postsecondary institutions -- earnings-enhancing, competitive, and Historically Black Colleges and Universities (HBCUs).…
