Are Preschool Programs Becoming Less Effective?
High-quality preschool programs are heralded as an effective policy tool to promote the development and life-long wellbeing of children from low-income families. Yet evaluations of recent preschool programs produce puzzling findings, including negative impacts, and divergent, weaker results than… more →
The Long-Term Effect of North Carolina’s Pre-Kindergarten Program is Larger in School Districts with Lower Rates of Growth in Academic Achievement
Prior research has found that public investments in North Carolina’s pre-kindergarten program—NC Pre-K—generated positive effects on student reading and math achievement through eighth grade (Bai et al., 2020). This study examined whether the effect of NC Pre-K funding exposure is moderated by… more →
Fadeout and Persistence of Intervention Impacts on Social-Emotional and Cognitive Skills in Children and Adolescents: A Meta-Analytic Review of Randomized Controlled Trials
Researchers and policymakers aspire for educational interventions to change children’s long-run developmental trajectories. However, intervention impacts on cognitive and achievement measures commonly fade over time. Less is known, although much is theorized, about socialemotional skill… more →
The Impact of Dual Enrollment on College Application Choice and Admission Success
Dual enrollment (DE) is one of the fastest growing programs that support the high school-to-college transition. Yet, there is limited empirical evidence about its impact on either students’ college application choices or admission outcomes. Using a fuzzy regression discontinuity approach on data… more →
Is Big Data Better? LMS Data and Predictive Analytic Performance in Postsecondary Education
Colleges have increasingly turned to data science applications to improve student outcomes. One prominent application is to predict students’ risk of failing a course. In this paper, we investigate whether incorporating data from learning management systems (LMS)--which captures detailed… more →
The Effects of In-School Virtual Tutoring on Student Reading Development: Evidence from a Short-Cycle Randomized Controlled Trial
This paper describes a 12-week cluster randomized controlled trial that examined the efficacy of BookNook, a virtual tutoring platform focused on reading. Cohorts of first- through fourth-grade students attending six Rocketship public charter schools in Northern California were randomly assigned… more →
Constrained Agency and the Architecture of Educational Choice: Evidence from New York City
Many school districts consider family preferences in allocating students to schools. In theory, this approach provides traditionally disadvantaged families greater access to high-quality schools by weakening the link between residential location and school assignment. We leverage data on the… more →
Challenges and opportunity: An examination of barriers to postsecondary academic success
Community colleges are a critical component of the U.S. higher education system, providing access to students from traditionally underserved communities. However, enduring challenges to completion stemming from educational, economic, and social inequities persist. Building on prior work that… more →
Politics and Children’s Books: Evidence from School Library Collections
The recent spike in book challenges has put school libraries at the center of heated political debates. I investigate the relationship between local politics and school library collections using data on books with controversial content in 6,631 public school libraries. Libraries in conservative… more →
PLUS or Minus? The Effect of Graduate School Loans on Access, Attainment, and Prices
In 2006, the federal government effectively uncapped student borrowing for graduate programs with the introduction of the Graduate PLUS loan program. Access to additional federal loans increased graduate students’ borrowing and shifted the composition of their loans from private to federal debt.… more →
What we teach about race and gender: Representation in images and text of children’s books
Books shape how children learn about society and norms, in part through representation of different characters. We introduce new artificial intelligence methods for systematically converting images into data and apply them, along with text analysis methods, to measure the representation of skin… more →
When your bootstraps are not enough: How demand and supply interact to generate learning in settings of extreme poverty
How much does family demand matter for child learning in settings of extreme poverty? In rural Gambia, families with high aspirations for their children’s future education and career, measured before children start school, go on to invest substantially more than other families in the early years… more →
Signals, Information, and the Value of College Names
Colleges can send signals about their quality by adopting new, more alluring names. We study how this affects college choice and labor market performance of college graduates. Administrative data show name-changing colleges enroll higher-aptitude students, with larger effects for alluring-but… more →
Patterns, Determinants, and Consequences of Ability Tracking: Evidence from Texas Public Schools
Schools often track students to classes based on ability. Proponents of tracking argue it is a low-cost tool to improve learning since instruction is more effective when students are more homogeneous, while opponents argue it exacerbates initial differences in opportunities without strong… more →
Heterogeneity in Labor Market Returns to Master’s Degrees: Evidence from Ohio
Graduate education is among the fastest growing segments of the U.S. higher educational system. This paper provides up-to-date causal evidence on labor market returns to Master’s degrees and examines heterogeneity in the returns by field area, student demographics and initial labor market… more →
Segregating Gotham's Youngest: Racial/Ethnic Sorting and the Choice Architecture of New York City’s Pre-K for All
New York City’s Pre-K for All (PKA) is the Nation’s largest universal early childhood initiative, currently serving some 70,000 four-year-olds. Stemming from the program’s choice architecture as well as the City’s stark residential segregation, PKA programs are extremely segregated by… more →
The Impact of Natural Disasters on Human Capital
We show that natural disasters affect a region’s aggregate human capital through at least four channels. In addition to causing out-migration, natural disasters reduce student achievement, lower high school graduation rates, and decrease post-secondary attendance. We estimate that disasters that… more →
When Do Informational Interventions Work? Experimental Evidence from New York City High School Choice
This paper reports the results of a large, school-level randomized controlled trial evaluating a set of three informational interventions for young people choosing high schools in 473 middle schools, serving over 115,000 8th graders. The interventions differed in their level of customization to… more →
Pension Reform and Labor Supply
As unfunded pension liabilities grow, governments experiment with ways to curb costs. We examine the effect of a representative cost-cutting reform on the retention and productivity of workers. The reform reduced pension annuities and increased penalties for early retirement, projected to save 8… more →
The ‘Good’ Schools: Academic Performance Data, School Choice, and Segregation
We examine the effects of disseminating academic performance data—either status, growth, or both—on parents’ school choices and their implications for racial, ethnic, and economic segregation. We conduct an online survey experiment featuring a nationally representative sample of parents and… more →
