To examine how human capital accumulation influences both economic growth and income inequality, we carefully endogenize the demand and supply of skills. We explicitly introduce the costs and externalities in education, and examine how both relate to learning-by-doing and R&D intensity. In...

Existing growth research provides little explanation for the very large differences in long-run growth performance across OECD countries. We show that cognitive skills can account for growth differences within the OECD, whereas a range of economic institutions and quantitative measures of...

I take advantage of a sharp discontinuity in the probability of admission to an elite university at the admission score threshold, to estimate causal returns to college education quality. I use a newly constructed dataset, which combines individual administrative records about high school,...

This paper views teacher quality through the human capital perspective. Teacher quality exhibits substantial growth over teachers’ careers, but why it improves is not well understood. I use a human capital production function nesting On-the-Job-Training (OJT) and Learning-by-Doing (LBD) and...

This paper studies how linear tax and education policy should optimally respond to skill-biased technical change (SBTC). SBTC affects optimal taxes and subsidies by changing i) direct distributional benefits, ii) indirect redistributional effects due to wage-(de)compression, and iii) education...

Wages grow but also become more unequal as workers age. Using German administrative data, we largely attribute both life-cycle facts to one driving force: some workers progress in hierarchy to jobs with more responsibility, complexity, and independence. In short, they climb the career ladder....

Using Swedish population register data on cohorts born 1982-1994 (N=1,087,750), we examine the effects of preterm births on school grades using sibling fixed effect models which compare individuals with their non-preterm siblings. We test for heterogeneous effects by degree of prematurity, as...

Workers acquire skills through formal schooling, through training provided by governments, and through training provided by firms. This chapter reviews, synthesizes, and augments the literature on the last of these, which has languished in recent years despite the sizable contribution of firm...

This paper uses an overlapping generations framework to analyze the implications of different financing regimes in the education sector for human capital formation and economic welfare. Agents privately invest in education after they have received a noisy information signal about their...
