"The Challenges of Measuring School Quality: Implications for Educational Equity" (with Susanna Loeb), in Education, Democracy and Justice, edited by Danielle S. Allen and Rob Reich (University of Chicago Press, 2013).
Explores the complexity of defining and measuring education quality in a way that can help public decision making. We explore the advantages and disadvantages of different approaches and highlight the merits of each with respect to different normative equity standards.
"Education and Poverty: Confronting the Evidence (Presidential Address to the Association for Public Policy Analysis and Management)" Journal of Policy Analysis and Management 31, no. 2 (2012): 203-227.
Discusses how current U.S. policy initiatives to improve the U.S. education system, including No Child Left Behind, test-based evaluation of teachers, and the promotion of competition, are misguided because they either deny or set to the side the clear evidence that students from disadvantaged households on average perform less well in school than those from advantaged households.
"From Birth to School: Early Childhood Initiatives and Third Grade Outcomes in North Carolina," (with Clara Muschkin and Kenneth Dodge), Association for Public Policy Analysis and Management, January 31, 2011.

Measures the community wide effects on third grade tests scores of two well-known programs in North Carolina in contrast to other studies of early childhood programs that focus on individual participants. We conclude that each of the programs generated large and positive effects.

"Teacher Mobility, School Segregation, and Pay-Based Policies to Level the Playing Field" (with Charles T. Clotfelter and Jacob L. Vigdor). Education, Finance and Policy 6, no. 3 (2011).
Finds how, in this empirical study of teacher mobility in North Carolina, schools with very high proportions of minority students would have to pay teacher salaries more than 50 percent higher than those in other schools to retain teachers with strong qualifications.
"Weighted Student Funding in the Netherlands: A Model for the U.S?" (with Edward B. Fiske). Journal of Policy Analysis and Management 30, no. 3 (2011): 470-498.
Shows how the Netherlands demonstrates the potential for a country to fund its schools in a highly progressive manner. Cultural and institutional differences between the U.S. and the Netherlands, however, limit the direct applicability of the Dutch model to the funding of schools within U.S. cities.
"When Schools Compete: A Cautionary Tale" (with Edward B. Fiske) (Brookings Institution Press, 2002).
Examines how New Zealand’s highly touted experience with self-governing schools, parental choice and competition during the 1990s highlights the potential downsides for the U.S. and other countries of reforms that embrace those concepts.
