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...

This paper presents a tractable framework for studying frictionless matching in school, work, and marriage when individuals have heterogeneous social and cognitive skills. In the model, there are gains to specialization and team production, but specialization requires communication and...

Over the past two decades, technological progress has been biased towards making skilled labor more productive. What does skill-biased technological change imply for business cycles? To answer this question, we construct a quarterly series for the skill premium from the CPS and use it to...

The phenomenon of workers moving from a poor to a rich economy is high on the political agenda. When a worker moves to a richer economy, what is gained by the move? The empirical challenge in giving an answer stems from the difficulty to disentangle income differences from many other...

I study the long-term effects of landing a first job at a large firm versus a small one using Spanish social security data. Size could be a relevant employer attribute for inexperienced workers since large firms are associated with greater training, higher wages, and enhanced productivity. The...

The public sector hires disproportionately more educated workers. Using US microdata, we show that the education bias also holds within industries and in two thirds of 3-digit occupations. To rationalize this finding, we propose a model of private and public employment based on two features....

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...

Why has the college wage premium risen rapidly in the United States since the 1980s, but not in European economies such as Germany? We argue that differences in employment protection can account for much of the gap. We develop a model in which firms and workers make relationship-specific...

We examine how changes in task content over time condition occupational wage development. Using survey data from Germany, we document substantial heterogeneity in within-occupational changes in task content. Combining this evidence with administrative data on individual employment outcomes over...

We present a structural framework for the evaluation of public policies intended to increasejob search intensity. Most of the literature defines search intensity as a scalar that influencesthe arrival rate of job offers; here we treat it as the number of job applications that workerssend out....
