The causal effect of education on earnings

01 Jan 1999-Handbook of Labor Economics (Elsevier)-pp 1801-1863
TL;DR: This paper surveys the recent literature on the causal relationship between education and earnings and concludes that the average (or average marginal) return to education is not much below the estimate that emerges from a standard human capital earnings function fit by OLS.
Abstract: This paper surveys the recent literature on the causal relationship between education and earnings. I focus on four areas of work: theoretical and econometric advances in modelling the causal effect of education in the presence of heterogeneous returns to schooling; recent studies that use institutional aspects of the education system to form instrumental variables estimates of the return to schooling; recent studies of the earnings and schooling of twins; and recent attempts to explicitly model sources of heterogeneity in the returns to education. Consistent with earlier surveys of the literature, I conclude that the average (or average marginal) return to education is not much below the estimate that emerges from a standard human capital earnings function fit by OLS. Evidence from the latest studies of identical twins suggests a small upward "ability" bias -- on the order of 10%. A consistent finding among studies using instrumental variables based on institutional changes in the education system is that the estimated returns to schooling are 20-40% above the corresponding OLS estimates. Part of the explanation for this finding may be that marginal returns to schooling for certain subgroups -- particularly relatively disadvantaged groups with low education outcomes -- are higher than the average marginal returns to education in the population as a whole.

TL;DR: In this article, independent single-equation models and structural equation models are used to analyze both direct and indirect impacts of education length, and of the match between education and employment, on job satisfaction after controlling for individual-specific and job-specific attributes, including health status and wages.
Abstract: Independent single-equation models and structural equation models are used to analyze both direct and indirect impacts of education length, and of the match between education and employment, on job satisfaction after controlling for individual-specific and job-specific attributes, including health status and wages The main results show that: (1) education/job mismatches, both in level and domain, reduce utility from work irrespective of schooling years and other individual/job characteristics; (2) the effects of education on job satisfaction are mainly indirect effects transmitted though the influence of schooling on workers’ health status, wages and other observable job characteristics; and (3) neglecting the structure of covariance among the determinants of job satisfaction results in upward bias in the estimation of the direct effect of schooling length, and in downward bias in the estimates for the effects of other personal circumstances

TL;DR: This article investigated whether returns to schooling in Ethiopia vary across the wage distribution of individuals, using an instrumental variables quantile regression framework that allows for both endogeneity of schooling resulting from unmeasured ability, and possible heterogeneity in the impact of schooling.
Abstract: This paper investigates whether returns to schooling in Ethiopia vary across the wage distribution of individuals. To do so, it adopts an instrumental variables quantile regression framework that allows for both endogeneity of schooling resulting from unmeasured ability, and possible heterogeneity in the impact of schooling. The empirical estimates indicate that education contributes more to the earnings of individuals at a lower end of the income distribution.

TL;DR: This paper used a tracer survey of secondary school completers in Tanzania to analyse the impact of educational qualifications on labour market earnings and found that the rates of return to the highest educational qualifications for wage employees are not negligible and, at the margin, provide an investment incentive.
Abstract: This study uses a tracer survey of secondary school completers in Tanzania to analyse the impact of educational qualifications on labour market earnings. We show that the rates of return to the highest educational qualifications for wage employees are not negligible and, at the margin, provide an investment incentive. However, we find little evidence of human capital effects in the earnings determination process for the self-employment sector. Introducing controls for father's educational background and a set of school fixed effects designed to proxy for school quality and potential labour market network effects reduces the estimated rates of return to educational qualifications. A comparison of our results with the available evidence from other countries in the region suggest that, despite an extremely small secondary and university education system, the private rates of return to education in the Tanzanian wage employment sector are comparatively low.

TL;DR: The Oaxaca/Blinder decomposition as discussed by the authors shows that the gender pay gap in the gross monthly salary can hardly be explained using the human capital approach and that women are paid less than men in typical women's jobs.
Abstract: Although there are a variety of studies on the gender pay gap, only a few relate to managerial positions. The present study attempts to fill this gap. Managers in private companies in Germany are a highly selective group of women and men, who differ only marginally in their human capital endowments. The Oaxaca/Blinder decomposition shows that the gender pay gap in the gross monthly salary can hardly be explained using the human capital approach. Adding variables on gender-specific labor market segregation and dimensions of the household and family to the model allows more than two-thirds of the gender pay gap to be explained. However, taking selection effects in a managerial position into account (Heckman correction), the proportion explained decreases to only one-third. This reveals the real extent to which women are disadvantaged on the labor market. In addition, we observe not only that the wages in typical women’s jobs are lower than in typical men’s jobs but also that women are paid less than men in typical women’s jobs. The two-thirds of the gender pay gap that remain unexplained represent the unobserved heterogeneity. This includes, for example, general societal and cultural conditions as well as structures and practices on the labor market and in companies that subject women to pay discrimination and pose an obstacle to them breaking the glass ceiling.
