We study how class size and class composition affect the academic and labor market performance of college students, two crucial policy questions given the secular increase in college enrollment. Our identification strategy relies on the random assignment of students to teaching classes. We find...

Recent studies based on US data have provided evidence to suggest that the 'quarter of birth' (QOB) may be endogenous and that the use of QOB as an instrumental variable will consequently produce inconsistent estimates (see Buckles and Hungerman, 2013). Such potential endogeneity is addressed in...

In the 1970s, the American Economic Association (AEA) was one of several professional associations to launch a summer program with the goal of increasing racial and ethnic diversity in its profession. In this paper we estimate the effectiveness of the AEA's program which, to the best of our...

Governments are making it a priority to upgrade information and communication technologies (ICT) with the aim to increase available internet connection speeds. This paper presents a new empirical strategy to estimate the causal effects of these policies, and applies it to the questions of...

College admissions officers face a rapidly changing policy environment where court decisions have limited the use of affirmative action. At the same time, there is mounting evidence that commonly used signals of college readiness, such as the SAT/ACTs, are subject to race and socioeconomic bias....

Recent studies show that programs offering structured, one-on-one coaching and tutoring tend to have large effects on the academic outcomes of both high school and college students. These programs are often costly to implement and difficult to scale, however, calling into question whether making...

Recent research has focused on what shapes gender differences in academic achievement and students' choice of university field of study. In this paper we examine how teachers' gender role attitudes and stereotypes influence the gender gap by affecting the school environment. We explore the...

We develop an overlapping generations general equilibrium model of the U.S. economy with heterogeneous consumers who face idiosyncratic earnings and health risk to study the implications of increasing college attainment, decreasing fertility, and increasing longevity (2005–2100). While all...

We develop and calibrate an overlapping generations general equilibrium model of the U.S. economy with heterogeneous consumers who face idiosyncratic earnings and health risk to study the implications of exogenous trends in increasing college attainment, decreasing fertility, and increasing...

This paper estimates the effect of paid employment on grades of full-time, four-year students from four nationally representative cross sections of the Harvard College Alcohol Study administered during 1993-2001. The relationship could be causal in either direction and is likely contaminated by...
