This paper examines the effects of a massive salt iodization program on human capital formation of school-aged children in China. Exploiting province and time variation, we find a strong positive impact on cognition for girls and no effects for boys. For non-cognitive skills, we find the...

This study exploits experimental variation in parent human capital (early-life school-based deworming) and a shock to schooling (extended Covid closures) to estimate how these factors interact in the production of child human capital within a sample of 3,500 Kenyan 3-8 year olds. Parents with...

This paper estimates the heterogeneous labor market effects of enrolling in higher education short-cycle (SC) programs. Expanding access to these programs might affect the behavior of some students (compliers) in two margins: the expansion margin (students who would not have enrolled in higher...

I apply Ricardo’s principle of comparative advantage to a theory of factor substitutability in a model with a continuum of worker and job types. Highly skilled workers have a comparative advantage in complex jobs. The model satisfies the distance-dependent elasticity of substitution (DIDES)...

In the Netherlands auditors can be trained in a part-time educational track in which students combine working and studying or in a full-time educational track. The former training is relatively firm-specific whereas the latter training is relatively general. Applying human capital theory, we...

There are many reasons to want measures of countries' investments in human capital and especially their investments in formal education. We review the existing literature on the measurement of human capital. Broadly speaking, economists have proposed three approaches to the measurement of human...

This paper synthesizes what economists have learned about human capital since Becker (1962) into four stylized facts. First, human capital explains at least one-third of the variation in labor earnings within countries and at least half of the variation across countries. Second, human capital...

In the three decades before the pandemic, mean achievement of U.S. 8th graders in math rose by more than half a standard deviation on the National Assessment of Educational Progress (NAEP). Between 2019 and 2022, U.S. students had forfeited 40 percent of that rise. To anticipate the consequences...

This paper investigates the relation between human capital andretirement when the age of retirement is endogenous. This relation isexamined in a life-cycle earnings model. An employee works full timeuntil retirement. The worker accumulates human capital by training-on-the-job and by...

We apply theories of capital market failure to ana1yzeoptima1 financing of risky higher education. In the market solution,students can only finance their education through debt. There isunderinvestment in human capita1, because some students with socia1lyprofitable investments in human capita1...
