This essay discusses the effect of technical change on wage inequality. I argue that the behavior of wages and returns to schooling indicates that technical change has been skill-biased during the past sixty years. Furthermore, the recent increase in inequality is most likely due to an...

While the utopian vision of the current Information Age was that computerization would flatten economic hierarchies by democratizing information, the opposite has occurred. Information, it turns out, is merely an input into a more consequential economic function, decision-making, which is the...

This paper examines the tradeoff between early and late specialization in the context of higher education. While some educational systems require students to specialize early by choosing a major field of study prior to entering university, others allow students to postpone this choice. I develop...

Nearly 60 percent of college students today are women. Using longitudinal data on a nationally representative cohort of eighth grade students in 1988, I examine two potential explanations for the differential attendance rates of men and women -- returns to schooling and non-cognitive skills. The...

We examine the effects of malaria on educational attainment and income by exploiting geographic variation in malaria prevalence in India prior to a nationwide eradication program in the 1950s. We find that the program led to modest increases in income for prime age men. This finding is robust to...

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....

This paper examines minority-white wage gaps. Neal and Johnson (1996) show that controlling for ability measured in the teenage years eliminates young adult wage gaps for all groups except for black males, for whom they eliminate 70% of the gap. Their study has been faulted because minority...

What is the impact of the minimum wage on the college wage premium? I show that job-ladder models imply that the effect should be small on impact---raising only the wages of workers bound by the minimum wage---and grow over time as workers slowly move up the job ladder. Guided by my theory, I...

The existing literature on skill-biased technical change has not considered how the technological endowment itself plays a role in the returns to skill. This paper constructs a simple model of skill biased technical change which highlights the role that resource endowments play in the returns to...

How do college students and postsecondary institutions react to changes in skill demand in the U.S. labor market? We quantify the magnitude and nature of response in the 4-year sector using a new measure of labor demand at the institution-major level that combines online job ads with geographic...
