The private return to postsecondary investment varies widely by field, but the resources required by different fields are not well known. This paper establishes five new facts about college costs using novel department-level data. First, costs vary widely across field, ranging from electrical engineering (109 percent higher costs than English) to…

This paper explores differences in the frequency with which students from different schools reach high levels of math achievement. Data from the American Mathematics Competitions is used to produce counts of high-scoring students from more than two thousand public, coeducational, non-magnet, non-charter U.S. high schools. High-achieving students…

Some scholars view academic and industrial science as qualitatively different knowledge production regimes. Others claim that the two sectors are increasingly similar. Large-scale empirical evidence regarding similarities and differences, however, has been missing. Drawing on prior work on the organization of science, we first develop a framework…

Even as research has begun to document that teachers matter, there is less certainty about what attributes of teachers make the most difference in raising student achievement. Numerous studies have estimated the relationship between teachers' characteristics, such as work experience and academic performance, and their value-added to student…

An emerging economic literature over the past decade has made use of international tests of educational achievement to analyze the determinants and impacts of cognitive skills. The cross-country comparative approach provides a number of unique advantages over national studies: It can exploit institutional variation that does not exist within…

This paper addresses three basic questions about an under-studied food subsidy program, the Child and Adult Care Food Program (CACFP): (1) Does CACFP reach targeted low-income children? (2) How do eligible families and child care providers who participate differ from those who do not participate? (3) What is the association between attending…

It is widely documented that U.S. students score below their OECD counterparts on international achievement tests, but it is less commonly known that ultimately, U.S. native adults catch up. In this paper, we explore institutional explanations for differences in the evolution of literacy over young adulthood across wealthy OECD countries. We use…

This paper discusses (a) the role of cognitive and noncognitive ability in shaping adult outcomes, (b) the early emergence of differentials in abilities between children of advantaged families and children of disadvantaged families, (c) the role of families in creating these abilities, (d) adverse trends in American families, and (e) the…

This paper presents a model where human capital differences--rather than technology differences--can explain several central phenomena in the world economy. The results follow from the educational choices of workers, who decide not just how long to train, but also how broadly. A "knowledge trap" occurs in economies where skilled workers favor…

This paper explores the phenomenon referred to as test score inflation, which occurs when achievement gains on "high-stakes" exams outpace improvements on "low-stakes" tests. The first part of the paper documents the extent to which student performance trends on state assessments differ from those on the National Assessment of…

Three factors help to explain why school enrollments in the Northern United States were higher than those in the South and in most of Europe by 1850. One was affordability: the northern states had higher real incomes, cheaper teachers, and greater local tax support. The second was the greater autonomy of local governments. The third was the…

Many test-based accountability systems, including the No Child Left Behind Act of 2001 (NCLB), place great weight on the numbers of students who score at or above specified proficiency levels in various subjects. Accountability systems based on these metrics often provide incentives for teachers and principals to target children near current…
