Schools often track students to classes based on ability. Proponents of tracking argue it is a low-cost tool to improve learning since instruction is more effective when students are more homogeneous, while opponents argue it exacerbates initial differences in opportunities without strong...

We explore the role that physicians play in moderating compliance with recommended vaccinations. Using administrative data on the universe of Danish children and their healthcare providers, we first construct and validate a measure of providers' propensities to comply with recommended...

Improving public sector workforce quality is challenging in sectors such as education where worker productivity is difficult to assess and manager incentives are muted by political and bureaucratic constraints. In this paper, we study how providing improved information to principals about...

Student disability rates have grown by over 50 percent over the past two decades and are continuing to rise. Policy discussion has linked this trend to state funding formulas that reward local school districts for identifying additional students with special needs. However, there is little...

School choice has become an increasingly prominent strategy for urban school districts seeking to enhance academic achievement. Evaluating the impact of such programs is complicated by the fact that a highly select sample of students takes advantage of these programs. To overcome this...

Beginning in 1998, all students in the state of Texas who graduated in the top ten percent of their high school classes were guaranteed admission to any in-state public higher education institution, including the flagships. While the goal of this policy is to improve college access for...

In this paper, we examine whether expanded access to sought-after schools can improve academic achievement. The setting we study is the "open enrollment" system in the Chicago Public Schools (CPS). We use lottery data to avoid the critical issue of non-random selection of students into schools....

We explore the extent to which schools manipulate the composition of students in the test-taking pool in order to maximize ratings under Texas' accountability system in the 1990s. We first derive predictions from a static model of administrators' incentives given the structure of the ratings...

The focus on efficiency costs in the empirical literature on Disability Insurance (DI) provides a misleading view of the adequacy of payment levels. In order to evaluate whether workers are over- or under-insured through the social insurance program, we develop a framework that allows us to...

Entrepreneurial activity is presumed to generate important spillovers, potentially justifying tax subsidies. How does the tax law affect individual incentives? How much of an impact has it had in practice? We first show theoretically that taxes can affect the incentives to be an entrepreneur due...
