This paper examines international and domestic collaborations using data from an original survey of corresponding authors and Web of Science data of articles that had at least one US coauthor in the fields of Particle and Field Physics, Nanoscience and Nanotechnology, and Biotechnology and...

This paper uses the random assignment of playing partners in professional golf tournaments to test for peer effects in the workplace. We find no evidence that the ability of playing partners affects the performance of professional golfers, contrary to recent evidence on peer effects in the...

While much has been written about the potential benefits of mentoring in academia, very little research documents its effectiveness. We present data from a randomized controlled trial of a mentoring program for female economists organized by the Committee for the Status of Women in the Economics...

Each year, graduate students entering the academic job market worry that they will suffer due to uncontrollable macroeconomic risk. Given the importance of general human capital and the relative ease of publicly observing productivity in academia, one might expect unlucky graduating cohorts'...

This paper assesses the relative importance of various explanations for the gender gap in career outcomes for highly-educated workers in the U.S. corporate and financial sectors. The careers of MBAs, who graduated between 1990 and 2006 from a top U.S. business school, are studied to understand...

Twenty-five cohorts of medical students were asked in their first and fourth year of school to estimate contemporaneous physician income in six different specialties. The students' income estimation errors varied systematically over time and cross-sectionally by specialty and type of student....

Hierarchies allow individuals to leverage their knowledge through others' time. This mechanism increases productivity and amplifies the impact of skill heterogeneity on earnings inequality. To quantify this effect, we analyze the earnings and organization of U.S. lawyers and use the equilibrium...

This study uses a human capital model to estimate the societal cost of producing a physician service. Physician human capital consists of the underlying human capital (productivity) of those who become physicians and the job-specific investments (physician training) added to this underlying...

We provide evidence that firms appoint independent directors who are overly sympathetic to management, while still technically independent according to regulatory definitions. We explore a subset of independent directors for whom we have detailed, micro-level data on their views regarding the...

I study the human capital development and firm-worker matching processes for PhD economists. This group is useful for this purpose because the types of jobs they hold can be easily categorized and they have an observable productivity measure (that is, publications.) I derive a two-period model...
