The U.S. labor market will be buffeted by major changes in the next few decades, such as an aging population, automation that displaces workers and requires skill adjustments, and increases in independent or informal work and "fissured" workplaces. These forces will likely raise worker...

In this paper I note the basic paradox of workforce development policy: that, in an era in which skills are more important than ever as determinants of labor market earnings, we spend fewer and fewer public (federal) dollars on workforce development over time. I present trends in funding and how...

We study the job training provided under the US Workforce Investment Act (WIA) to adults and dislocated workers in two states. Our substantive contributions center on impacts estimated non-experimentally using administrative data. These impacts compare WIA participants who do and do not receive...

We offer an integrated explanation and empirical analysis of the polarization of U.S. employment and wages between 1980 and 2005, and the concurrent growth of low skill service occupations. We attribute polarization to the interaction between consumer preferences, which favor variety over...

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...
