Heterogeneous Effects of Violence on Student Achievement
In this paper, I study the causal relationship between violence and human capital accumulation. Due to a power vacuum left in conflict zones of Colombia after the 2016 peace agreement, large spikes in violence were reported in the municipalities of the country dominated by the rebel group FARC.… more →
Screening with Multitasking: Theory and Empirical Evidence from Teacher Tenure Reform
What happens when employers screen their employees but only observe a subset of output? We specify a model with heterogeneous employees and show that their response to the screening affects output in both the probationary period and the post-probationary period. The post-probationary impact is… more →
Variation in the Relationship between School Spending and Achievement: Progressive Spending Is Efficient
Tags: Human capitalThe equity-efficiency tradeoff and cumulative return theories predict larger returns to school spending in areas with higher previous investment in children. Equity – not efficiency – is therefore used to justify progressive school funding: spending more in communities with fewer financial… more →
Excellence for all? University honors programs and human capital formation
Tags: Human capital, EquityCan public university honors programs deliver the benefits of selective undergraduate education within otherwise nonselective institutions? We evaluate the impact of admission to the Honors College at Oregon State University, a large nonselective public university. Admission to the Honors… more →
When expectation isn’t reality: Racial disparities in overestimation and STEM attrition among first-year students in college
Existing research indicates that racially minoritized students with similar academic preparation are less likely than their represented peers to persist in STEM, raising the question of factors that may contribute to racial disparities in STEM participation beyond academic preparation. We extend… more →
Two Years Later: How COVID-19 has Shaped the Teacher Workforce
The unprecedented challenges of teaching during COVID-19 prompted fears of a mass exodus from the profession. We examine the extent to which these fears were realized using administrative records of Massachusetts teachers between 2015-16 and 2021-22. Relative to pre-pandemic levels, average… more →
Unintended Consequences of Expanding Teacher Preparation Pathways: Does alternative licensure attenuate new teacher pay?
Texas reduced new teacher preparation requirements in 2001 to allow more alternate paths to licensure. Within five years, this policy change resulted in over half the state’s new teachers being alternatively licensed.
The Impact of Natural Disasters on Human Capital
Tags: Human capitalWe 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 →
Job Training Programs as Crime Deterrents? Evidence from a Low-Income Targeted Training Program RCT
The primary goal of job training programs is to improve employment and earning outcomes of participants. However, effective job training programs may have potential secondary benefits, including in the form of reduced arrests. In this paper, we evaluate the impact of a job training program in… more →
Local Supply, Temporal Dynamics, and Unrealized Potential in Teacher Hiring
We explore the dynamics of competitive search in the K-12 public education sector. Using data from Boston Public Schools, we document how teacher labor supply varies substantially by position types, schools, and the timing of job postings. We find that early-posted positions are more likely to… more →
Paraeducators: Growth, Diversity and a Dearth of Professional Supports
Paraeducators perform multiple roles in U.S. classrooms, including among others preparing classroom activities, working with students individually and in small groups, supporting individualized programming for students with disabilities, managing classroom behavior, and engaging with parents and… more →
The Inequitable Effects of Teacher Layoffs: What We Know and Can Do
Economic downturns can cause major funding shortfalls for U.S. public schools, often forcing districts to make difficult budget cuts including teacher layoffs. In this brief, we synthesize the empirical literature on the widespread teacher layoffs caused by the Great Recession. Studies find that… more →
Informal social interactions, behavior, and academic achievement
Topics: Student LearningWe study the effects of informal social interactions on academic achievement and behavior using idiosyncratic variation in peer groups stemming from changes in bus routes across elementary, middle, and high school. In early grades, a one standard-deviation change in the value-added of same-grade… more →
Reaping the Rewards Later: How Education Improves Old-Age Cognition in South Africa

Using various proxy measures of cognitive performance from a longitudinal survey in South Africa,… more →
White Advantage in Teacher Assignment
Using detailed classroom-level data for North Carolina, we build on previous research to examine racial gaps in access to high-quality teachers. We calculate the exposure of White, Black and Hispanic students to teachers with various characteristics in 4th grade, 7th grade math and English, and… more →
School-based Mentoring Relationships and Human Capital Formation
Topics: Student LearningWe document a largely unrecognized pathway through which schools promote human capital development – by fostering informal mentoring relationships between students and school personnel. Using longitudinal data from a large, nationally representative sample of adolescents, we explore the… more →
Labor Market Signaling and the Value of College: Evidence from Resumes and the Truth
Tags: Higher education, Human capitalHow do college non-completers list schooling on their resumes? The negative signal of not completing might outweigh the positive signal of attending but not persisting. If so, job-seekers might hide non-completed schooling on their resumes. To test this we match resumes from an online jobs board… more →
Effects of Perceived Productivity on Study Effort: Evidence from a Field Experiment
Topics: Student LearningTags: Motivation, Human capitalHow does the perceived relationship between effort and achievement affect effort? To answer this question, I conduct a field experiment with a popular online learning platform. I exogenously manipulate students’ beliefs about returns to effort by assigning them to different information… more →
