This paper documents an unusual and possibly significant phenomenon: The export of skills embodied in goods, services, or capital from poorer to richer countries. We first present a set of stylized facts. Using a measure that combines the sophistication of a country's exports with the average...

This paper revisits traditional human capital models and proposes a new conceptual framework of human capital accumulation, anchored in skills development, to illustrate the phenomenon and implications of youth economic disengagement. In the framework, youth economic disengagement is defined as...

The fallout of nitrogen pollution is considered one of the largest global externalities facing the world, impacting air, water, soil, and human health. This paper combines data from the Demographic and Health Survey data set across India, Vietnam, and 33 African countries to analyze the causal...

The authors follow the Hellerstein, Neumark, and Troske (1999) framework to estimate marginal productivity differentials and compare them with estimated relative wages. The analysis provides evidence on productivity and nonproductivity-based determinations of wages. Special emphasis is given to...

Uses of main primary energy resources, such as coal, oil, and solid biomass, are directly linked with adverse impacts on human health. Air pollution emitted from various activities in the energy supply chains is the main risk factor to human health, along with accidental and occupational risk...

Firms that provide on-the-job training do so when it is critical to their productivity -- and when productivity is critical to their survival. This paper begins by confirming a significant and positive return from on-the-job training on wages and productivity, as well as the presence of positive...

This paper develops a multi-sector, small open economy Dynamic Stochastic General Equilibrium model, which includes the accumulation of human capital, built via public expenditures in education and health. Four possible fiscal rules are examined for total public investment in infrastructure,...

This paper reviews the evidence on the importance of human capital for macro-economic development. Through the lens of a simple aggregate production function, human capital might increase output per capita by directly entering in the production process, incentivising the accumulation of...

This paper describes the methodology for a new World Bank Human Capital Index (HCI). The HCI combines indicators of health and education into a measure of the human capital that a child born today can expect to obtain by her 18th birthday, given the risks of poor education and health that...
