Inequality
This paper studies the causal impacts of public universities on the outcomes of their marginally admitted students. I use administrative admission records spanning all 35 public universities in Texas, which collectively enroll 10 percent of American public university students, to systematically identify and employ decentralized cutoffs in SAT/ACT scores that generate discontinuities in admission and enrollment. The typical marginally admitted student completes an additional year of education in the four-year sector, is 12 percentage points more likely to earn a bachelor's degree, and eventually earns 5-10 percent more than their marginally rejected but otherwise identical counterpart. Marginally admitted students pay no additional tuition costs thanks to offsetting grant aid; cost-benefit calculations show internal rates of return of 19-23 percent for the marginal students themselves, 10-12 percent for society (which must pay for the additional education), and 3-4 percent for the government budget. Finally, I develop a method to disentangle separate effects for students on the extensive margin of the four-year sector versus those who would fall back to another four-year school if rejected. Substantially larger extensive margin effects drive the results.
This study examines the impact of special education on academic and behavioral outcomes for students with learning disabilities (LD) by using statewide Indiana data covering kindergarten through eighth grade. The results from student fixed effects models show that special education services improve achievement in math and English Language Arts, but they also increase suspensions and absences for students with LD. These effects vary across student subgroups, including gender, race/ethnicity, eligibility for free or reduced-price lunch, and English language learner status. The findings reveal both the significant benefits and unintended consequences of special education services for students with LD, highlighting the complex dynamics and varying effects of special education.
While learning outcomes in low- and middle-income countries are generally at low levels, the degree to which students and schools more broadly within education systems lag behind grade-level proficiency can vary significantly. A substantial portion of existing literature advocates for aligning curricula closer to the proficiency level of the “median child” within each system. Yet, amidst considerable between-school heterogeneity in learning outcomes, choosing a single instructional level for the entire system may still leave behind those students in schools far from this level. Hence, establishing system-wide curriculum expectations in the presence of significant between-school heterogeneity poses a significant challenge for policymakers — especially as the issue of between-school heterogeneity has been relatively unexplored by researchers so far. This paper addresses the gap by leveraging a unique dataset on foundational literacy and numeracy outcomes, representative of six public educational systems encompassing over 900,000 enrolled children in South Asia and West Africa. With this dataset, we examine the current extent of between-school heterogeneity in learning outcomes, the potential predictors of this heterogeneity, and explore its potential implications for setting national curricula for different grade levels and subjects. Our findings reveal that between-school heterogeneity can indeed present both a severe pedagogical hindrance and challenges for policymakers, particularly in contexts with relatively higher levels of performance and in the higher grades. In response to meaningful between-system heterogeneity, we also demonstrate through simulation that a more nuanced, data-driven targeting of curricular expectations for different schools within a system could empower policymakers to effectively reach a broader spectrum of students through classroom instruction.
Recent work highlights the challenge of scaling evidence-based educational programs. We report on a randomized controlled trial of a financial incentive program designed to increase the efficacy of a national remote college advising initiative for high-achieving students. We find substantial positive effects of the program on student engagement with college advisors; applications to well-matched colleges and universities; and review of financial aid awards. Yet treated students were no more likely to enroll at higher-quality institutions. Student survey responses suggest that institutional admissions and affordability barriers, alongside student preferences to attend institutions closer to home, explain the lack of enrollment effects.
Correspondence audits document causal evidence of racial/ethnic discrimination in many contexts. However, few studies have examined whether local political party voting context influences individuals to engage in “stakeholder-centric” discrimination on behalf of or in response to expectations of others. We examine heterogeneity in racial/ethnic discrimination by the county-level Republican vote share with a correspondence audit of 52,792 K-12 public-school principals across 33 states. We email principals posing as parents considering a move to the school district and requesting a meeting. We find evidence that the county-level Republican vote share strongly moderates racial/ethnic discrimination against Black and Chinese American families. While all groups are less likely to receive a response from principals as the Republican vote share increases, the declines for Black and Chinese American families are largest. Thus, discrimination against Black and Chinese American families is sizable in counties with the highest Republican vote share. These findings shed light on how partisanship can shape the experiences of historically marginalized groups. Furthermore, there may be benefits to targeting limited resources to geographies where discrimination is more likely to occur.
While Hispanic students represent the fasting-growing segment of the American school-age population, substantial gaps exist in college enrollment and Bachelor’s attainment between Hispanic and White and Asian students. Numerous factors contribute to these disparities and disproportionally affect Hispanic youth. In this paper, we contribute evidence on the impact of an intensive college advising program on Hispanic students’ college participation and degree attainment. We report on a multi-cohort randomized controlled trial of College Forward, which provides individualized advising from junior year of high school through college for a majority Hispanic, lower-income student population in Texas. Students who receive College Forward advising are 7.1 percentage points more likely to earn a Bachelor’s degree within 5 years of high school graduation; this effect appears largely driven by shifting high school graduates from the extensive margin of not going to college at all to instead enroll at four-year colleges and universities. Despite the costs associated with intensive advising programs like College Forward, back of the envelope calculations suggest that the benefit from increased college graduation induced by the program outweighs operating costs in less than three years following college completion.
Public policies targeting individuals based on need often impose disproportionate burden on communities that lack the resources to implement these policies effectively. In an elementary school setting, I examine whether community-level interventions focusing on similar needs and providing resources to build capacity in these communities could improve outcomes by improving the effectiveness of individual-level interventions. I find that the extended school day policy that targets lowest-performing schools in reading in Florida significantly improved the effectiveness of the third-grade retention policy in these schools. These complementarities were large enough to close the gap in retention effects between targeted and higher-performing schools.
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 school choices made by over 233,000 New York City families to examine the extent to which the city’s school choice system fulfills this promise. We find that over-subscribed and high-quality schools enroll smaller proportions of students from traditionally disadvantaged families. We explore three mechanisms to explain this inequitable distribution: application timing, neighborhood stratification, and the architecture of the choice process itself. We find that all three mechanisms have a disequalizing influence and propose several policy shifts to address this inequality.
This paper investigates patterns of racial/ethnic and gender gaps in post-secondary degree attainment trajectories by the levels of students’ pre-college academic preparation. We follow four cohorts of Missouri public high school freshmen for five years beyond on-time graduation among White, Black, and Hispanic male and female students. A composite measure of pre-college academic preparation is constructed based on test scores, GPA, attendance, and advanced course enrollment, which we label Academic Index (AI) and split students into AI Quintiles for analysis. We find large racial/ethnic gaps in AI, with the largest difference for Black male students, who are heavily concentrated in the lowest quintile. Gender gaps in academic readiness widen during high school. College enrollment is higher for Black male and female students near the average AI and below, but this advantage completely disappears for degree completion. Hispanic-White gaps emerge earlier than that of Black-White gaps as Hispanic students are less likely to graduate from high school and attend college. An important finding is that top-performing Black and Hispanic male students have much lower rates of degree completion than other top-performing students. Also, Black-White gaps are much wider in any degree attainment than in bachelor’s degree attainment, suggesting lower likelihood of completing a sub-bachelor degree among Black students. After controlling for academic preparation and the FRL status, bachelor’s degree attainment among Black and Hispanic female students are similar to, or higher than, that of White female students.
We examine the fundamental and complex role that time plays in the learning process. We begin by developing a conceptual framework to elucidate the multiple obstacles schools face in converting total time in school into active learning time. We then synthesize the causal research and document a clear positive effect of time on student achievement of small to medium magnitude, but also with likely diminishing marginal returns. Further descriptive analyses reveal how large differences in the length of the school day and year across public schools are an underappreciated dimension of educational inequality in the United States. Finally, our case study of time loss in one urban district demonstrates the potential to substantially increase learning time within existing constraints.
