Much of education policy focuses on improving teacher quality, but most policies lack strong research support. We use student achievement gains to estimate teacher value-added, our measure of teacher quality. The analysis reveals substantial variation in the quality of instruction, most of which...

School choice policies may improve productivity if parents choose well-run schools, but not if parents primarily choose schools for their peer groups. Theoretically, high income families cluster near preferred schools in housing market equilibrium; these need only be effective schools if...

We study insurers' use of prescription drug formularies to screen consumers in the ACA Health Insurance Exchanges. We begin by showing that Exchange risk adjustment and reinsurance succeed in neutralizing selection incentives for most, but not all, consumer types. A minority of consumers,...

The purposes of this paper are to describe some conceptual and empirical foundations of "healthy-time" measures of health outcomes or healthcare quality, and to explore how to expand the empirical opportunities for measuring such outcomes using U.S. national survey data. To these ends, the paper...

As hospitals are increasingly held accountable for patients' post-discharge outcomes under new payment models, hospitals may choose to acquire skilled nursing facilities (SNFs) to better manage these outcomes. This raises the question of whether patients discharged to hospital-based SNFs have...

Despite strong demand for attending high schools with better peers, there is mixed evidence on whether doing so improves academic outcomes. We estimate the cognitive returns to high school quality using administrative data on a high-stakes college entrance exam in China. To overcome selection...

This paper extends the traditional test-score value-added model of teacher quality to allow for the possibility that teachers affect a variety of student outcomes through their effects on both students' cognitive and noncognitive skill. Results show that teachers have effects on skills not...

This paper provides evidence on the effect of electoral institutions on the performance of public officials. Using panel data on state supreme courts between 1947 and 1994, we measure the effects of changes in judicial electoral processes on judge work quality - as measured by citations by later...

In response to widespread dissatisfaction with the schools, the 1988 Chicago School Reform Act decentralized school governance by forming elected local school councils (LSCs) responsible for principal hiring, evaluation, and contract renewal as well as other management functions. Subsequent...

Conventional value-added models (VAMs) compare average test scores across schools after regression-adjusting for students' demographic characteristics and previous scores. This paper tests for VAM bias using a procedure that asks whether VAM estimates accurately predict the achievement...
