Although many U.S. state policies presume that human capital is important for state economic development, there is little research linking better education to state incomes. In a complement to international studies of income differences, we investigate the extent to which quality-adjusted...

There is limited existing evidence justifying the economic case for state education policy. Using newly-developed measures of the human capital of each state that allow for internal migration and foreign immigration, we estimate growth regressions that incorporate worker skills. We find that...

This paper studies empirically the effect of education policies on human capital and per capita income. The results suggest for European and OECD countries that higher attendance at pre-primary education, greater autonomy of schools and universities, a lower student-to-teacher ratio, higher age...

This paper offers a reappraisal of the impact of migration on economic growth for 22 OECD countries between 1986-2006 and relies on a unique data set we compiled that allows us to distinguish net migration of the native- and foreign-born populations by skill level. Specifically, after...

Economists use micro-based and macro-based approaches to assess the macroeconomic return to population health. The macro-based approach tends to yield estimates that are either negative and close to zero or positive and an order of magnitude larger than the range of estimates derived from the...

This paper uses a new measure of human capital, which distinguishes both quality and quantity components, to estimate the long-term effect of the Covid-19-related school closures on aggregate productivity through the human capital channel. Productivity losses build up over time and are estimated...

In addition to the humanitarian suffering and huge immediate economic costs, the war in Ukraine will have long-term consequences, among which are losses in human capital that will impact aggregate productivity for many years. Exploiting a new stock measure of human capital combining the quality...

How far is the world away from ensuring that every child obtains the basic skills needed to be internationally competitive? And what would accomplishing this mean for world development? Based on the micro data of international and regional achievement tests, we map achievement onto a common...

Between 1997 and 2014, US corn, soybean and cotton production almost fully converted to genetically modified crops. Starting around 2007, improved tight oil and shale gas technologies turned the declining US fossil fuel production into a booming industry. We study the effects of these two...
