Using microdata from the 1960-2000 decennial censuses, this paper explores how large initial differences in immigrant earnings by country of origin change with duration in the United States. One analysis reveals that country of origin adds less to the explanation of earnings, among working-age...

We present a novel theory that immigrants facilitate innovation and entrepreneurship by being willing and able to invest in new skills. Immigrants whose human capital is not immediately transferable to the host country face lower opportunity costs of investing in new skills or methods and will...

This paper describes the theoretical underpinnings and provides empirical evidence for a model that predicts a positive impact of immigration on entrepreneurial activity. Immigrants, we hypothesize, facilitate innovation and entrepreneurship by being willing and able to invest in new skills. At...

The initial earnings of U.S. immigrants vary enormously by country of origin. Via three interrelated analyses, we show earnings convergence across source countries with time in the United States Human-capital theory plausibly explains the inverse relationship between initial earnings and...

Historical, longitudinal data are used to track the earnings of cohorts of immigrant and U.S.-born women over time. The longitudinal data circumvent potential cohort biases that afflict cross-sectional analyses of immigrant earnings growth and biases due to immigrant emigration and other issues...

The labor market "quality" of immigrants is a subject of debate among immigration researchers, and a major public policy concern. However, traditional methods of measuring human capital are particularly difficult to apply to recently arrived immigrants. Many factors that have a negative effect...

This paper begins an exploration to determine whether earnings growth, as a measure of the propensity to invest in human capital, is a valuable variable for predicting mortality. To insure its robustness and general applicability to ongoing Social Security models, the usefulness of earnings...

This study enhances the 1973 CPS-IRS-SSA Exact Match File with more complete Social Security mortality data for 1973-1978 and with updated Social Security earnings and disability data. It uses the resulting data set to examine the effect of income, controlling for education, on the mortality of...
