This paper attempts to reconcile the contradictory findings in the debate over school resources and school effectiveness by highlighting the role of aggregation in the presence of omitted variables bias. While data aggregation for well-specified linear models yields unbiased parameter estimates,...

Search theory suggests that early career job changes lead to better matches that benefit both workers and firms, but this may not hold in teacher labor markets characterized by salary rigidities, barriers to entry, and substantial differences in working conditions. Of particular concern to...

Evaluation of the efficacy of school policies requires measures of student performance across schools and states, but conventional approaches to constructing the relevant data can be very misleading. This paper develops an approach to estimating marginal school effects at the state level. It...

Studies of the charter school sector typically focus on head-to-head comparisons of charter and traditional schools at a point in time, but the expansion of parental choice and relaxation of constraints on school operations is unlikely to raise school quality overnight. Rather, the success of...

Charter schools have become a very popular instrument for reforming public schools, because they expand choices, facilitate local innovation, and provide incentives for the regular public schools while remaining under public control. Despite their conceptual appeal, evaluating their performance...

Considerable controversy surrounds the impact of schools and teachers on the achievement of students. This paper disentangles the separate factors influencing achievement with special attention given to the role of teacher differences and other aspects of schools. Unique matched panel data from...

Most students change schools at some point in their academic careers, but some change very frequently and some schools experience a great deal of turnover. Many researchers, teachers, and administrators argue that mobility harms students, particularly disadvantaged students in high turnover,...

Substantial uncertainty exists about the impact of school quality on the black-white achievement gap. Our results, based on both Texas Schools Project (TSP) administrative data and the Early Childhood Longitudinal Survey (ECLS), differ noticeably from other recent analyses of the black-white...

While special education has become a hotly debated issue of school policy, most of the discussion has centered on the aggregate costs of providing mandated programs for disabled children. Little attention has been paid to the effectiveness of such programs or possible interactions with the...
