This paper analyzes the effect on earnings of the matching of English language skills to occupational requirements. It uses data from the Occupational Information Network (O*NET) database and a Realized Matches procedure to quantify expected levels of English skills in each of over 500...

This paper is concerned with the English language requirements (both level and importance) of occupations in the United States, as measured by the O*NET database. These scores are linked to microdata on employed adult (aged 25 to 64) males, both native born and foreign born, as reported in the...

This paper uses the approach in the under/over education literature to analyze the extent of matching of educational level to occupational attainment among adult native born and foreign born men in the U.S., using the 2000 Census. Overeducation is found to be more common among recent labor...

This paper examines the determinants of occupational attainment and the impact of occupation on earnings. Results for both the native born and foreign born are presented, and these provide insights as to the earnings penalties associated with the less-than-perfect international transferability...

This paper provides an introduction and overview of my research on the Economics of Language. The approach is that language skills among immigrants and native-born linguistic minorities are a form of human capital. There are costs and benefits associated with this characteristic embodied in the...

High- and low-wage occupations are expanding rapidly relative to middle-wage occupations in both the U.S. and the E.U. We study the reallocation of workers from middle-skill occupations towards the tails of the occupational skill distribution by analyzing changes in age structure within and...

We measure the extent to which skilled immigrants increase innovation in the United States by exploring individual patenting behavior as well as state-level determinants of patenting. The 2003 National Survey of College Graduates shows that immigrants patent at double the native rate, and that...

Using the 2003 National Survey of College Graduates, I examine how immigrants perform relative to natives in activities likely to increase U.S. productivity, according to the type of visa on which they first entered the United States. Immigrants who first entered on a student/trainee visa or a...

This paper examines whether the results of the earnings equation developed in the overeducation/required eduation/under-education (ORU) literature are sensitive to whether the usual or reference levels of education are measured using the Realized Matches or Worker Self-Assessment methods. The...

After a decade in which wages and employment fell precipitously in low-skill occupations and expanded in high-skill occupations, the shape of U.S. earnings and job growth sharply polarized in the 1990s. Employment shares and relative earnings rose in both low and high-skill jobs, leading to a...
