Estimates of the effect of education on GDP (the social return) have been hard to reconcile with micro evidence on the private return to schooling. We present a simple explanation combining two ideas: imperfect substitution and endogenous skill-biased technological progress and use cross-country...

When types of workers are imperfect substitutes, the Mincerian rate of return to human capital is negatively related to the supply of human capital. We work out a simple model for the joint evolution of output and wage dispersion. We estimate this model using cross-country panel data on GDP and...

We estimate the impact of schooling on monthly earnings from 1950 to 2000 in Romania. Nearly constant at about 3-4 percent during the socialist period, the coefficient on schooling in a conventional earnings regression rises steadily during the 1990s, reaching 8.5 percent by 2000. Our analysis...

This research examines how the earnings structure in the Czech Republic and Slovakia changed after the collapse of those countries' Communist governments. Tests of four similar micro-data sets show that returns to education rose significantly with the transition to non-Communist governments. For...

Recent studies have shown that trade liberalization increases skilled wage premiums in developing countries. This result suggests globalization may benefit elite skilled workers relatively more than poor unskilled workers, increasing inequality. This effect may be mitigated, however, if human...

The paper introduces a new measure of educational mismatch at the firm level, constructed by merging firm and individual data at the sector-firm size-year level. This measure captures both the intensity of mismatch and its type - whether overeducation, undereducation, or a mix of the two. We...

This paper studies households' expenditure on the education of children in China's cities to assess how internal migrant families' investment in the human capital of their offspring differs from that of local urban families. The private education-related expenditure reflects both households'...

The Infant Health and Development Program (IHDP) was designed to promote the development of low-birth weight (up to 2,500 grams) and premature (up to 37 weeks gestational age) infants. There is evidence that the IHDP intervention, a randomly-assigned bundle of services including primarily free,...
