State differences in pathways to school leadership and in achievement growth
Diversity trends among faculty in STEM and non-STEM fields at selective public universities in the U.S. from 2016 to 2023
During the 2015–2016 academic year, racial protests swept across college campuses in the U.S. These protests were followed by large university investments in initiatives to promote diversity, which combined with existing diversity dynamics, have helped to shape recent faculty diversity trends. We document diversity trends among faculty in STEM and non-STEM fields since the protests in 2015–2016. We find that recent diversity trends are narrowing …

The Narrowing Gender Wage Gap Among Faculty at Public Universities in the U.S
We study the conditional gender wage gap among faculty at public research universities in the U.S. We begin by using a cross-sectional dataset from 2016 to replicate the long-standing finding in research that, conditional on rich controls, female faculty earn less than their male colleagues. Next, we construct a data panel to track the evolution of the wage gap through 2021. We show that the gender wage gap is narrowing. It declined by more than …

The formalized processes districts use to evaluate mathematics textbooks
Textbooks are a widely used educational intervention that can affect student achievement, and the marginal cost of choosing a more effective textbook is typically small. However, we know little about how textbooks get from the publisher to the classroom. The purpose of this paper is to investigate the ways mathematics textbook adoption practices vary and predict adoption decisions. We use interviews with district leaders in a stratified random sa…
Public Accountability and Nudges
In the summer of 2013, the National Council on Teacher Quality (NCTQ) issued public ratings of teacher education programs. We provide the first empirical examination of NCTQ ratings, beginning with a descriptive overview of the ratings and how they evolved from 2013–2016. We also report on results from an information experiment built around the initial ratings release. In the experiment we provided targeted information about specific programmatic…

Representation and Salary Gaps by Race-Ethnicity and Gender at Selective Public Universities
We use data from 2015–2016 to document faculty representation and wage gaps by race-ethnicity and gender in six fields at selective public universities. Consistent with widely available information, Black, Hispanic, and female professors are underrepresented and White and Asian professors are overrepresented in our data. Disadvantaged minority and female underrepresentation is driven predominantly by underrepresentation in science and math intens…
The Impact of Performance Ratings on Job Satisfaction for Public School Teachers
Spurred by the federal Race to the Top competition, the state of Tennessee implemented a comprehensive statewide educator evaluation system in 2011. The new system is designed to increase the rigor of evaluations and better differentiate teachers based on performance. The use of more differentiated ratings represents a significant shift in education policy. We merge teacher performance evaluations from the new system with data from post-evaluatio…
Pension Enhancements and the Retention of Public Employees
The authors use data from workers in the largest public-sector occupation in the United States-teaching-to examine the effect of pension enhancements on employee retention. Specifically, they study a 1999 enhancement to the benefit formula for public school teachers in St. Louis, Missouri, that resulted in an immediate and dramatic increase in their incentives to remain in covered employment. To identify the effect of the enhancement on teacher r…
Benefit or Burden? On the Intergenerational Inequity of Teacher Pension Plans
Most public school teachers in the United States are enrolled in defined benefit (DB) pension plans. Using administrative microdata from four states, combined with national pension funding data, we show these plans have accumulated substantial unfunded liabilities—effectively debt—owing to previous plan operations. On average across 49 state plans, an amount that exceeds 10% of current teachers’ earnings is being set aside to pay for previously a…

Do Employers Prefer Workers Who Attend For-Profit Colleges? Evidence from a Field Experiment
This paper reports results from a resume-based field experiment designed to examine employer preferences for job applicants who attended for-profit colleges. For-profit colleges have seen sharp increases in enrollment in recent years despite alternatives such as public community colleges being much cheaper. We sent almost 9,000 fictitious resumes of young job applicants who recently completed their schooling to online job postings in six occupati…
Teacher Pension Systems, the Composition of the Teaching Workforce, and Teacher Quality
The Integrating and Segregating Effects of School Choice
We evaluate the integrating and segregating effects of three distinct school choice programs in San Diego. We go beyond the traditional question of racial integration and examine the integration of students by test scores, parental education levels, and language status. In addition to measuring the net integrative effects of school choice, we also examine the underlying motives behind student participation in school choice programs and the limiti…
