This paper explores how the specification of the earnings function impacts the optimal tax treatment of human capital. If education is complementary to labor effort, education should be subsidized to offset tax distortions on labor supply. However, if most of the education is enjoyed by high...

In a model with ex-ante homogenous households, earnings risk and a general earnings function, we derive the optimal linear labor tax rate and optimal linear education subsidies. The optimal income tax trades off social insurance against incentives to work and to invest in human capital....

We extract estimation results on the Mincer earnings function from four earlier studies and add new results from a recent dataset. We analyse differences related to differences in earnings concepts, in sampling frame and differences among studies that cannot be explained. Jointly, the studies...

This paper develops a dynamic general equilibrium model to highlight the role of human capital accumulation of agents differentiated by skill type in the joint determination of social mobility and the skill premium. We first show that our model captures the empirical co-movement of the skill...

This study estimates the effect of compulsory schooling on earnings. For identification, I exploit a German reform that extended the duration of secondary schooling in the 1960s. I find that hourly wages increase by 6%-8% per additional year of schooling. This result challenges prior findings...

Since the development of human capital theory, countless estimates of the economic benefits of investing in education for the individual have been published. While it is a universal fact that in all countries of the world the more education one has the higher his or her earnings, it is...

The objective of this paper is to construct and quantitatively assess an equilibrium search model with on-the-job search and general human capital accumulation. In the model workers enter the labor market with different abilities and firms differ in their productivities. Wages are dispersed...

How important is mastering information and communication technology (ICT) in modern labor markets? We answer this question with unique data on ICT skills tested in 19 countries. Our two instrumental-variable models exploit technologically induced variation in broadband Internet availability that...

Students around the world are going to school but are not learning -- an emerging gap in human capital formation. To understand this gap, this paper introduces a new data set measuring learning in 164 countries and territories. The data cover 98 percent of the world's population from 2000 to...

In many low-income countries, teachers do not master the subject they are teaching, and children learn little while attending school. Using unique data from nationally representative surveys of schools in seven Sub-Saharan African countries, this paper proposes a methodology to assess the effect...
