We began by asking whether the decline in employment among those with disabilities was broad-based or narrowly focused, explained by population shifts or changes in behavior and/or opportunities among those with disabilities, or simply reflective of exogenous deteriorations in health, relatively...

We investigate the effects of employer-provided health insurance on the labor supply of married women. Because health benefits commonly are restricted to full-time workers, wives who prefer to work short hours but have no alternate source of insurance may work long hours in order to acquire...

A new and highly controversial literature argues that the employment of working-age people with disabilities fell dramatically relative to the rest of the working-age population in the 1990s. Some dismiss these results as fundamentally flawed because they come from a self-reported work...

The positive correlations found between computer use and human capital are often interpreted as evidence that the adoption of computers have raised the relative demand for skilled labor, the widely touted skill-biased technological change hypothesis. However, several models argue the...

The wage premium for high-skilled workers in the United States, measured as the ratio of the 90th-to-10th percentiles from the wage distribution, increased by 20 percent from the 1970s to the late 1980s. A large literature has emerged to explain this phenomenon. A leading explanation is that...

Regional inequality in China appears to be persistent and even growing in the last two decades. We study potential explanations for this phenomenon. After making adjustments for the difference in the cost of living across provinces, we find that some of the inequality in real wages could be...

We discover and document errors in public use microdata samples ("PUMS files") of the 2000 Census, the 2003-2006 American Community Survey, and the 2004-2009 Current Population Survey. For women and men ages 65 and older, age- and sex-specific population estimates generated from the PUMS files...
