This paper presents a simple framework that illustrates the link between skill-based wage differentiation and human capital acquisition given skill-biased technical progress. The analysis points to the economic costs resulting from labor market and income redistribution policies that prevent the...

In 1910, 12 percent of American 14-17 year olds were enrolled in high school; by 1930, enrollment had increased to 50 percent; enrollment in Britain was 12 percent in 1950. This paper argues that by increasing the skill premium, the massive inflows of European unskilled immigrants at the turn of...

This paper documents that inequality in labor earnings increased substantially during the economic transition in Poland. One surprising result is that earnings inequality increased markedly in both the private and public sectors, indicating that even state-owned enterprises in Poland moved...

A key feature of developing economies is that wages in agriculture are significantly below those of other sectors. Using Brazilian household surveys and administrative panel data, I use information on workers who switch sectors to decompose the drivers of this gap. I find that most of the gap is...

We introduce a new suite of macroeconomic models that extend and complement the Debt, Investment, and Growth (DIG) model widely used at the IMF since 2012. The new DIG-Labor models feature segmented labor markets, efficiency wages and open unemployment, and an informal non-agricultural sector....

Liberia is facing large infrastructure gaps and developmental needs that constrain the country’s growth potential. The government has set an ambitious agenda to transform the economy and to reach middle-income country status by 2030 by scaling up investment in infrastructure and human capital....

Africa will account for 80 percent of the projected 4 billion increase in the global population by 2100. The accompanying increase in its working age population creates a window of opportunity, which if properly harnessed, can translate into higher growth and yield a demographic dividend. We...

We examine the issue of technical assistance versus brain drain repatriation as alternative strategies for transferring scarce skills to a skill-poor economy. Technical assistance relies mainly on expatriate skills and labor from the host country, while brain drain repatriation seeks to effect a...

This paper formulates a simple aggregate growth model that is capable of assessing the impact of macroeconomic policies on the long-term performance of a developing country. The model emphasizes expenditures on human capital and the dynamics of external debt, and yields empirically testable...

This paper studies the effects that the inability of individuals to borrow against future income has on economic growth. The model assumes that human capital, which is accumulated through education, is the only factor of production. It is shown that liquidity constraints reduce growth. Further,...
