Is Education Consumption or Investment? Implications for School Competition
Friedman (1955) argued that giving parents freedom to choose schools would improve education. His argument was simple and compelling because it extended results from markets for consumer goods to education. We review the evidence, which yields surprisingly mixed results on Friedman's prediction… more →
Heat and Learning
We demonstrate that heat inhibits learning and that school air-conditioning may mitigate this effect. Student fixed effects models using 10 million PSAT-retakers show hotter school days in years before the test reduce scores, with extreme heat being particularly damaging. Weekend and summer… more →
Government Privatization and Political Participation: The Case of Charter Schools
Governments around the world have privatized public services in the name of efficiency and citizen empowerment, but some argue that privatization could also affect citizen participation in democratic governance. We explore this possibility by estimating the impact of charter schools (which are… more →
School District Operational Spending and Student Outcomes: Evidence from Tax Elections in Seven States
We use close tax elections to estimate the impact of school district funding increases on operational spending and student outcomes across seven states. Districts with passing levies directed new revenue toward support services and instructor salaries but did not increase teacher staffing levels… more →
Policy Implementation, Principal Agency, and Strategic Action: Improving Teaching Effectiveness in New York City Middle Schools
Ten years ago, the reform of teacher evaluation was touted as a mechanism to improve teacher effectiveness. In response, virtually every state redesigned its teacher evaluation system. Recently, a growing narrative suggests these reforms failed and should be abandoned. This response may be… more →
Delayed Benefits: Effects of California School District Bond Elections on Achievement by Socioeconomic Status
Contradictory evidence of the relationship between education funding and student achievement could reflect heterogeneous effects by revenue source or student characteristics. This study examines potential heterogeneous effects of a particular type of local revenue – bond funds for capital… more →
Interpreting Effect Sizes of Education Interventions
Researchers commonly interpret effect sizes by applying benchmarks proposed by Cohen over a half century ago. However, effects that are small by Cohen’s standards are large relative to the impacts of most field-based interventions. These benchmarks also fail to consider important differences in… more →
Engaging Teachers: Measuring the Impact of Teachers on Student Attendance in Secondary School
Teachers’ impact on student long-run success is only partially explained by their contributions to students’ short-run academic performance. For this study, we explore a second dimension of teacher effectiveness by creating measures of teachers’ contributions to student class-attendance. We find… more →
