This paper investigates how increases in concentration can be interrupted or reversed by changes in how firms compete on quality. We examine the U.S. hotel industry during the past half century. We document that starting in the early 1980s, quality competition came more in the form of costs that...

In November of 2007, the New York City Department of Education assigned elementary and middle schools a letter grade (A to F) under a new accountability system. Grades were based on numeric scores derived from student achievement and other school environmental factors such as attendance, and...

In this paper we study the effects of the threat of school vouchers and school stigma in Florida on the performance of "low-performing" schools using student-level data from a subset of districts. Estimates of the change in school-level high-stakes test scores from the first year of the reform...

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...
