The apparently unrelenting growth in the GDP-share of health spending (SHS) has been a perennial issue of policy concern. Does an equilibrium limit exist? The issue has been left open in recent dynamic models which take income growth and population aging as given. We view these variables as...

Taller workers are paid higher wages. A prominent explanation for this pattern is that physical growth and cognitive development share childhood inputs, inducing a correlation between adult height and two productive skills: strength and intelligence. This paper explores the relative roles of...

A growing literature documents the links between long-term outcomes and health in the fetal period, infancy, and early childhood. Much of this literature focuses on rich countries, but researchers are increasingly taking advantage of new sources of data and identification to study the long reach...

One of the most basic predictions of human capital theory is that life expectancy should impact human capital investment. Limited exogenous variation in life expectancy makes this difficult to test, especially in the contexts most relevant to the macroeconomic applications. We estimate the...

Student employment subsidies are one of the largest types of federal employment subsidies, and one of the oldest forms of student aid. Yet it is unclear whether they help or harm students' long term outcomes. We present a framework that decomposes overall effects into a weighted average of...

In the face of declining state support, many universities have introduced differential pricing by undergraduate program as an alternative to across-the-board tuition increases. This practice aligns price more closely with instructional costs and students' ability to pay post-graduation....

Banking reforms--that reduced interest rates--boosted college enrollment rates among able students from middle class families. We define "able" students as those with learning aptitude scores in the top two-thirds of the U.S. population. We define "middle class" as families in which both parents...

We review studies of the impact of credit constraints on the accumulation of human capital. Evidence suggests that credit constraints are increasingly important for schooling and other aspects of households' behavior. We highlight the importance of early childhood investments, since their...

Recent cohorts of college enrollees are more likely to work, and work substantially more, than those of the past. October CPS data reveal that average labor supply among 18 to 22-year-old full-time undergraduates nearly doubled between 1970 and 2000, rising from 6 hours to 11 hours per week. In...

Estimates using admissions lotteries suggest that urban charter schools boost student achievement, while charter schools in other settings do not. We explore student-level and school-level explanations for these differences using a large sample of Massachusetts charter schools. Our results show...
