This paper analyzes the factors underlying the evolution of the worldwide distribution of skills and their implications for global inequality. We develop and parameterize a two-sector, two-class, world economy model that endogenizes education and mobility decisions, population growth, and income...

International migration is a selective process that induces ambiguous effects on human capital and economic development in countries of origin. We establish the theoretical micro-foundations of the relationship between selective emigration and human capital accumulation in a multi-country...

This paper has two main objectives. First, it assesses and measures the gaps in the stock of human capital across the world. It presents how effectively different regions are improving their stock of human capital, and how long it will take for developing countries to catch up with the current...

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...

The World Health Organization estimates that 300 million clinical cases of malaria occur annually and also observed that during the 80's and part of the 90's its incidence increased noticably. There are basically two factors behind the incidence of malaria: 'geographical destiny' and...

Government income and housing interventions during the COVID pandemic had demonstrable benefits in reducing the growth of homelessness. Comparisons of projected versus actual growth in Los Angeles County from 2020 to 2022 validate the benefit of these interventions.This report offers three types...

This paper examines the potential impacts of East-West migration of talents on the innovative capital and hence the long-run growth prospects in Eastern sending countries. Complementing previous studies, we examine the impact of high skill migration not only on the formation of human capital,...

Owing to lack of relevant data on health human resource (HHR) migration, the empirical dimension of the health-worker crisis debate has remained void despite abundant theoretical literature. A health worker crisis is overwhelming the world. Shortages in health professionals are reaching...
