We study the forces driving polarization and higher wage inequality since 1980 using a structural model of occupation choice in the tradition of Roy (1951). In our model, changes in relative occupational skill prices proxy for changes in relative demand for occupational labor services. Our...

We argue that college students' field-of-study choices significantly influence how economies respond to labor market disruptions. To do so, we develop and estimate a framework featuring forward-looking students who choose a field of study when entering college, and subsequently make decisions...

A growing empirical literature attributes much of the productivity advantages of large, "superstar" firms to their adoption of best practice management techniques that allow them to better identify and use talented workers. The reasons for the incomplete adoption of these "structured management...

We review theoretical and empirical work on the economic effects of the United States and China trade relations during the last decades. We first discuss the origins of the China shock, its measurement, and present methods used to study its economic effects on different outcomes. We then focus...

This paper examines the productivity (and wage) gains from locating in dense, urban environments. We distinguish between three potential explanations of why firms are willing to pay urban workers more: (1) the urban wage premium is spurious and is the result of omitted ability measures, (2) the...

How worker productivity evolves with tenure and experience is central to economics, shaping, for example, life-cycle earnings and the losses from involuntary job separation. Yet, worker-level productivity is hard to identify from observational data. This paper introduces direct measurement of...

The costs of low-carbon energy fell dramatically over the past decade, leading to rapid growth in its deployment. However, many challenges remain to deploy low-carbon energy at a scale necessary to meet net zero carbon emission targets. If net zero goals are to be met, developing complementary...
