Can brick phones bridge the digital learning divide? Evidence from SMS-based math practice
Hardware requirements are a barrier to widespread adoption of digital learning software among low-income populations. We investigate the demand among smallholder-farming households for a simple, adaptive math learning tool that can be accessed by widely available ``brick'' phones, and its effect… more →
Choosing Alone? Peer Similarity in High School Choices
We provide a descriptive analysis of within-school and neighborhood similarity in high school applications in New York City. We depart from prior work by examining similarity in applications to specific schools rather than preferences for school characteristics. We find surprisingly low… more →
Out of Sight, Out of Mind? The Gap between Students’ Test Performance and Teachers’ Estimations in India and Bangladesh
This is one of the first studies of the mismatch between students’ test scores and teachers’ estimations of those scores in low- and middle-income countries. Prior studies in high-income countries have found strong correlations between these metrics. We leverage data on actual and estimated… more →
Lottery-Based Evaluations of Early Education Programs: Opportunities and Challenges for Building the Next Generation of Evidence
Lottery-based identification strategies offer potential for generating the next generation of evidence on U.S.
When Girls Outperform Boys: The Gender Gap in High School Math Grades
Across an array of educational outcomes, evidence suggests that girls outperform boys on average. For example, in Chicago, ninth-grade girls earn math GPAs that are 0.29 points higher than boys on average. This paper examines explanations for this gap, such as girl-boy differences in academic… more →
Does High School Size Affect Rates of Risky Health Behaviors and Poor Mental Health Among Low-Income Teenagers? Evidence from New York City
There is increasing concern about risky behaviors and poor mental health among school-aged youth. A critical factor in youth well-being is school attendance. This study evaluates how school organization and structure affect health outcomes by examining the impacts of a popular urban high school… more →
Leaving to Fit In: School Leadership, Peer Teacher Relationships, and Turnover Among Teachers of Color in New York City
Disparate turnover among teachers of color remains a persistent educational challenge, yet little research explores the link between school leadership, peer teaching staff, and turnover disparities. This study explores whether principal and peer teacher demographics predict teacher turnover in… more →
Cramming: Short- and Long-Run Effects
An administrative rule allowed students who failed an exam to retake it shortly after, triggering strong `teach to the test' incentives to raise these students' test scores for the retake. We develop a model that accounts for truncation and find that these students score 0.14 standard deviations… more →
Increasing success in higher education: The relationships of online course taking with college completion and time-to-degree
Online courses provide flexible learning opportunities, but research suggests that students may learn less and persist at lower rates compared to face-to-face settings. However, few research studies have investigated more distal effects of online education. In this study we analyzed six years of… more →
Resegregated Schools, Racial Attitudes, and Long-Run Partisanship: Evidence for White Backlash
Brown v. Board (1954) catalyzed a nationwide effort by the federal judiciary to desegregate public schools by court order, representing a major achievement for the U.S. civil rights movement. Four decades later, courts began dismissing schools from desegregation decrees in a staggered fashion,… more →
Does Where Students Come From Affect Where Teachers Go?
We show that fade out biases value-added estimates at the teacher-level. To do so, we use administrative data from North Carolina and show that teachers' value-added depend on the quality of the teacher that preceded them. Value-added estimators that control for fade out feature no such teacher… more →
Coal Use and Student Performance
We examine the effect of air pollution from power production on students' cognitive outcomes by leveraging year-to-year production variation, wind patterns, and plant closures. We find that every one million megawatt hours of coal-fired power production decreases student performance in schools… more →
Do Peers Affect Undergraduates’ Decisions to Switch Majors?
This study used college dormitory room and social group assignment data to investigate the peer effect on the probability of college students switching their major fields of study. The results revealed strong evidence of peer effects on students’ decisions to switch majors. In particular, the… more →
Air Filters, Pollution and Student Achievement
This paper identifies the achievement impact of installing air filters in classrooms for the first time. To do so, I leverage a unique setting arising from the largest gas leak in United States history, whereby the offending gas company installed air filters in every classroom, office and common… more →
Timing in Early Childhood Education: How Cognitive and Achievement Program Impacts Vary by Starting Age, Program Duration, and Time Since the End of the Program
This paper uses meta-analytic techniques to estimate the separate effects of the starting age, program duration, and persistence of impacts of early childhood education programs on children’s cognitive and achievement outcomes. It concentrates on studies published before the wide scale… more →
Horizontal Differentiation and the Policy Effect of Charter Schools
While school choice may enhance competition, incentives for public schools to raise productivity may be muted if public education is viewed as imperfectly substitutable with alternatives. This paper estimates the aggregate effect of charter school expansion on education quality while accounting… more →
The Effects of Special Education on the Academic Performance of Students with Learning Disabilities
In the forty plus years since passage of the Individuals with Disabilities Education Act (IDEA), special education has grown in the number of students and amount spent on services. Despite this growth, the academic performance of students with disabilities (SWDs) remains troubling low… more →
A Reanalysis of Impacts of the Tennessee Voluntary Prekindergarten Program
We present a reanalysis of the Tennessee Voluntary Prekindergarten Program (TNVPK), a state-funded program designed to promote the school readiness of 4-year-olds from low-income families. Oversubscribed programs used a lottery to randomly assign prospective enrollees a chance to… more →
