Using detailed data from North Carolina, we examine the frequency, incidence, and consequences of teacher absences in public schools, as well as the impact of an absence disincentive policy. The incidence of teacher absences is regressive: schools in the poorest quartile averaged almost one...

We use data on statewide end-of-course tests in North Carolina to examine the relationship between teacher credentials and student achievement at the high school level. The availability of test scores in multiple subjects for each student permits us to estimate a model with student fixed...

Education researchers and policy makers agree that teachers differ in terms of quality and that quality matters for student achievement. Despite prodigious amounts of research, however, debate still persists about the causal relationship between specific teacher credentials and student...

Simple partial-equilibrium models suggest that income increases at the high end of the distribution can raise price paid by those at the low end of the income distribution. This prediction does not universally hold in a general equilibrium model, or in models where the rich and poor consume...

Using data for North Carolina public school students in grades 3 to 8, we examine achievement gaps between white students and students from other racial and ethnic groups. We focus on successive cohorts of students who stay in the state's public schools for all six years, and study both...

We use administrative data on North Carolina public schools to document the tendency for more highly qualified teachers to be matched with more advantaged students, and we measure the bias this pattern generates in estimates of the impacts of various teacher qualifications on student...

Analyzing data for the 100 largest school districts in the South and Border states, we ask whether there is evidence of "resegregation" of school districts and whether levels of segregation can be linked to judicial decisions. We distinguish segregation measures indicating the extent of racial...

College attendance and completion in the U.S. are strongly correlated with race and socioeconomic background. Do public postsecondary institutions themselves exacerbate pre-college disparities, or reduce them? We address this question using longitudinal data linking the records of students at...

When economic agents make decisions on the basis of an information set containing both a continuous variable and a discrete signal based on that variable, theory suggests that the signal should have no bearing on behavior conditional on the variable itself. Numerous empirical studies, many based...

This paper examines the effects of policies that increase the number of students who take the first course in algebra in 8th grade, rather than waiting until 9th grade. Extending previous research that focused on the Charlotte-Mecklenberg school system, we use data for the 10 largest districts...
