The history of coeducation in U.S. higher education is explored through an analysis of a database containing information on all institutions offering four-year undergraduate degrees that operated in 1897, 1924, 1934, or 1980, most of which still exist today. These data reveal surprises about the...

Recent work shows that peers affect student achievement, but the mechanisms are not well understood. I show that peer behavior is an important mechanism, perhaps more so than ability, by exploiting exogenous timing in diagnosis/treatment of ADD among peers that improves peer behavior while...

Mentoring has become an extremely popular policy for improving the retention and performance of new teachers, but we know little about its effects on teacher and student outcomes. I study the impact of mentoring in New York City, which adopted a nationally recognized mentoring program in 2004. I...

We use six years of data on student test performance to evaluate the effectiveness of certified, uncertified, and alternatively certified teachers in the New York City public schools. On average, the certification status of a teacher has at most small impacts on student test performance....

We confront two seemingly-contradictory observations about the US labor market: the rate at which workers change employers has declined since the 1980s, yet there is a commonly expressed view that long-term employment relationships are more difficult to attain. We reconcile these observations by...

This paper describes and tries to reconcile trends in alternative work arrangements in the United States using data from the Contingent Worker Survey supplements to the Current Population Survey (CPS) for 1995 to 2017, the 2015 RAND-Princeton Contingent Work Survey (CWS), and administrative tax...

The majority of labor transactions throughout much of history and a significant fraction of such transactions in many developing countries today are "coercive", in the sense that force or the threat of force plays a central role in convincing workers to accept employment or its terms. We propose...

We study the relationship between Hispanic employment and location-specific measures of the distribution of jobs. We find that it is only the local density of jobs held by Hispanics that matters for Hispanic employment, that measures of local job density defined for Hispanic poor English...

Using a large data set that links individual Current Population Survey (CPS) records to employer-reported administrative data, we document substantial discrepancies in basic measures of employment status that persist even after controlling for known definitional differences between the two data...

This study estimates the labor force participation rate (LFPR) of older males in Korea from 1955 to 2005, and analyzes the effects of several determining factors on labor force participation decisions at older ages. The LFPR of older men increased substantially from the mid-1960s to the...
