This paper examines the scalability of the results from the Tennessee Student-Teacher Achievement Ratio (STAR) Project, a prominent educational experiment. We explore how the misalignment between the experimental design and the econometric model affects researchers' ability to learn about the intervention's scalability. We document heterogeneity in compliance with class-size reduction that is more extensive than previously acknowledged and discuss its consequences for the evaluation of the experiment. Guided by this finding, we implement a new econometric framework incorporating heterogeneous treatment effects and endogenous class size determination. We find that the effect of class size on test scores differs considerably across schools, with only a small fraction of schools having significant benefits from reduced class sizes. We discuss the challenges this poses for the intervention's scalability and conclude by analyzing targeted class-size interventions.

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.

We define educational access as the component of a neighborhood's value that is determined by the set of schools available to its residents. This paper studies the extent to which educational access is determined by sorting based on heterogeneous preferences over school attributes, or local institutions that constrain residential location and school choice--such as school catchment areas and housing regulation. We develop a spatial equilibrium model of residential sorting and school choice, estimated using data from a large school district in the United States. The model replicates the responses of house prices and school enrollment to quasi-experimental variation in school peer composition and school transportation provision. We find that low-income families prioritize proximity to schools while high-income families and families with high-skilled children place more value on school peer composition. We use the model to evaluate how the geography of neighborhood sorting influences the aggregate and distributional outcomes of a school-choice expansion (place-based) and a housing voucher (people-based) policy. We find that both policies result in net welfare losses, with only marginal improvements in school peer composition for the average low-income family. Although eligible families benefit from these policies, the negative impact falls on families who currently invest in their children's education by residing in expensive neighborhoods. Under both policies, higher-income families are less exposed to the inflow of low-income children into their schools, either because of their longer distance from target neighborhoods or because of the cost imposed by residential zoning regulation on voucher recipients.

We present a model of endogenous schooling and earnings to isolate the causal effect of parents' education on children's education and earnings outcomes. The model suggests that parents' education is positively related to children's earnings, but its relationship with children's education is ambiguous. Identification is achieved by comparing the earnings of children with the same length of schooling, whose parents have different lengths of schooling. The model also features heterogeneous preferences for schooling, and is estimated using HRS data. The empirically observed positive OLS coefficient obtained by regressing children's schooling on parents' schooling is mainly accounted for by the correlation between parents' schooling and children's unobserved preferences for schooling. This is countered by a negative, structural relationship between parents' and children's schooling choices, resulting in an IV coefficient close to zero when exogenously increasing parents' schooling. Nonetheless, an exogenous one-year increase in parents' schooling increases children's lifetime earnings by 1.2 percent on average.

We study the effects of the unionization of faculty at Canadian universities from 1970-2022 using an event-study design. Using administrative data which covers the full universe of faculty salaries, we find strong evidence that unionization leads to both average salary gains and compression of the distribution of salaries. Our estimates indicate that salaries increase on average by 2 to over 5 percent over the first 6 years post unionization. These effects are driven largely by gains in the bottom half of the wage distribution with little evidence of any impact at the top end. Our evidence indicates that the wage effects are primarily concentrated in the first half of our sample period. We do not find any evidence of an impact on employment.

Transitional Kindergarten (TK) is a relatively recent entrant into the U.S. early education landscape, combining features of public pre-K and regular kindergarten. We provide the first estimates of the impact of Michigan's TK program on 3rd grade test scores. Using an augmented regression discontinuity design, we find that TK improves 3rd grade math scores by 0.29 standard deviations relative to a counterfactual that includes other formal and informal learning options. This impact is notably large relative to the prior pre-K literature. Estimates for English Language Arts (ELA) are imprecise but suggestive of a positive effect as well.

We study the Tutoring Online Program (TOP), where: (i) tutoring is entirely online; (ii) tutors are volunteer university students, matched with underprivileged middle school students. We leverage random assignment to estimate effects during and after the pandemic (2020 and 2022), investigating channels of impact. Three hours of individual tutoring per week increased math performance by 0.23 SD in 2020 and 0.20 SD in 2022. Higher-dosage yielded stronger effects, while group tutoring smaller effects. TOP enhanced students' aspirations, socio-emotional skills and psychological well-being, but only during school closures. We also estimate the impact of TOP on tutors, finding increases in empathy.

We conduct a survey-based experiment with 2,776 students at a non-profit university to analyze income insurance demand in education financing. We offered students a hypothetical choice: either a federal loan with income-driven repayment or an income-share agreement (ISA), with randomized framing of downside protections. Emphasizing income insurance increased ISA uptake by 43%. We observe that students are responsive to changes in contract terms and possible student loan cancellation, which is evidence of preference adjustment or adverse selection. Our results indicate that framing specific terms can increase demand for higher education insurance to potentially address risk for students with varying outcomes.

Using a rich dataset that merges student-level school records with birth records, and leveraging three alternative identification strategies, we explore how increase in access to charter schools in twelve districts in Florida affects students remaining in traditional public schools (TPS). We consistently find that competition stemming from the opening of new charter schools improves reading--but not math--performance and it also decreases absenteeism of students who remain in the TPS. Results are modest in magnitude.

College attendance has increased significantly over the last few decades, but dropout rates remain high, with fewer than half of all adults ultimately obtaining a postsecondary credential. This project investigates whether one-on-one college coaching improves college attendance and completion outcomes for former low- and middle-income income state aid recipients who attended college but left prior to earning a degree. We conducted a randomized control trial with approximately 8,000 former students in their early- to mid-20s. Half of participants assigned to the treatment group were offered the opportunity to receive coaching services from InsideTrack, with all communication done remotely via phone or video. Intent-to-treat analyses based on assignment to coaching shows no impacts on college enrollment and we can rule out effects larger than a two-percentage point (5%) increase in subsequent Fall enrollment.

We assess the role of information gaps in understanding gender differences in negotiation behavior by conducting a randomized information experiment on the 2018 to 2020 graduating cohorts of undergraduate business majors from Boston University. Prior to starting their job search, treated students were provided with objective information about the gender gap in negotiation among their peers along with the earnings changes conditional on negotiating. We find sizable immediate effects on negotiation intentions that persist to actual negotiation behavior, particularly for men. While the treatment affects women's negotiation behavior through belief-updating, the effects on men's behavior are primarily through increased salience of the information. Further, we find some evidence that gender-specific treatment spillovers likely contribute to the smaller average treatment effects on behavior for women. Overall, our findings suggest that such information interventions can help to nudge women who have potentially large financial returns to negotiation to realize these gains.

We examine the initial post-college geographic location decisions of students from hometowns in the Appalachian region that often lack substantial high-skilled job opportunities, focusing on the role of non-pecuniary considerations. Novel survey questions in the spirit of the contingent valuation approach allow us to measure the full non-pecuniary benefits of each relevant geographic location, in dollar equivalents. A new specification test is designed and implemented to provide evidence about the quality of these non-pecuniary measures. Supplementing perceived location choice probabilities and expectations about pecuniary factors with our new non-pecuniary measures allows us to estimate a stylized model of location choice and obtain a comprehensive understanding of the importance of pecuniary and non-pecuniary factors. We also combine the non-pecuniary measures with realized location and earnings outcomes to characterize inequality in overall welfare.

Programs that engage young children in movement and song to help them learn are popular but experimental evidence on their impact is sparse. We use an RCT to evaluate the effectiveness of Big Word Club (BWC), a classroom program that uses music and dance videos for 3-5 minutes per day to increase vocabulary. We conducted a field experiment with 818 preschool and kindergarten students in 47 schools in three U.S. states. We find that treated students scored higher on a test of words targeted by the program (0.30 SD) after four months of use and this effect persisted for two months.

What makes diversity unifying in some settings but divisive in others? We examine how the mixing of ethnic groups in German schools affects intergroup cooperation and trust. We leverage the quasi-random assignment of students to classrooms within schools to obtain variation in the type of diversity that prevails in a peer group. We combine this with a large-scale, incentivized lab-in-field-experiment based on the investment game, allowing us to assess the in-group bias of native German students in their interactions with fellow natives (in-group) versus immigrants (out-group). We find in-group bias peaks in culturally polarized classrooms, where the native and immigrant groups are both large, but have different religious or language backgrounds. In contrast, in classrooms characterized by non-cultural polarization, fractionalization, or a native supermajority, there are significantly lower levels of own-group favoritism. In terms of mechanisms, we find empirical evidence that culturally polarized classrooms foster negative stereotypes about immigrants' trustworthiness and amplify taste-based discrimination, both of which are costly and lead to lower payouts. In contrast, accurate statistical discrimination is ruled out by design in our experiment. These findings suggest that extra efforts are needed to counteract low levels of inclusivity and trust in culturally polarized environments.

Education is a crucial asset for a country's economic prospects and for its inhabitants. In addition to its direct impact on growth via the accumulation of human capital, it is a critical ingredient in producing an informed citizenry, enhancing their ability to obtain and exert human and political rights and their facility to adapt to changing environments (generated by, e.g., technological or climatic change) among other benefits. In this paper, we study education inequality in LAC (both in quantity and quality), assess how it emerges and amplifies or dampens existing inequalities, and examine the interaction of education inequality with other forms of inequality, primarily income and labor market outcomes. Our analysis is based on primary data from multiple sources.

We study how human capital diversification, in the form of double majoring, affects the response of earnings to labor market shocks. Double majors experience substantial protection against earnings shocks, of 56%. This finding holds across different model specifications and data sets. Furthermore, the protection double majors experience is more pronounced when the two majors are more distantly related, highlighting the importance of diverse skill sets. Additional analyses demonstrate that double majors are more likely to work in jobs that require a diverse set of skills and knowledge and are less likely to work in occupations that are closely related to their majors.

University-based scientific research has long been argued to be a central source of commercial innovation and economic growth. Yet at the same time, there have been long-held concerns that many university-based discoveries never realize their potential social benefits. Looking across universities, research and commercialization activities such as start-up formation vary tremendously -- variation that could reflect the composition and orientation of faculty research, university-level factors such as patenting and licensing efforts, or broader place-based factors such as location in a technology cluster. We take a first step towards unpacking this heterogeneity in university commercialization by analyzing how the propensity of academic research to spill over to commercial innovation changes when academics move across universities. Our estimates suggest that at least 15-25% of geographic variation in commercial spillovers from university-based research is attributable to place-specific factors.

This paper identifies which investments in school facilities help students and are valued by homeowners. Using novel data on school district bonds, test scores, and house prices for 29 U.S. states and a research design that exploits close elections with staggered timing, we show that increased school capital spending raises test scores and house prices on average. However, impacts differ vastly across types of funded projects. Spending on basic infrastructure (such as HVAC) or on the removal of pollutants raises test scores but not house prices; conversely, spending on athletic facilities raises house prices but not test scores. Socio-economically disadvantaged districts benefit more from capital outlays, even conditioning on project type and the existing capital stock. Our estimates suggest that closing the spending gap between high- and low-SES districts and targeting spending towards high-impact projects may close as much as 25% of the observed achievement gap between these districts.

This paper presents the results from a randomized controlled trial of Chapter One, an early elementary reading tutoring program that embeds part-time tutors into the classroom to provide short bursts of 1:1 instruction. Eligible kindergarten students were randomly assigned to receive supplementary tutoring during the 2021-22 school year (N=818). The study occurred in a large Southeastern district serving predominantly Black and Hispanic students. Students assigned to the program were over two times more likely to reach the program's target reading level by the end of kindergarten (70% vs. 32%). The results were largely homogenous across student populations and extended to district-administered assessments. These findings provide promising evidence of an affordable and sustainable approach for delivering personalized reading tutoring at scale.

This study finds substantial reductions to criminal activity from the introduction of a comprehensive high school support program for disadvantaged youth living in the largest public housing project in Toronto. The program, called Pathways to Education, bundles supports such as regular coaching, tutoring, group activities, free public transportation tickets and bursaries for postsecondary education. In this paper, we use a difference-in-differences approach that compares students living in public housing communities where the program was offered to those living in communities where the program was not offered over time. We find that eligibility for Pathways reduces the likelihood of being charged with a crime by 32 percent at its Regent Park location. This effect is driven by a reduction in charges for breaking and entering, theft, mischief, other traffic offenses and Youth Criminal Justice Act offenses.

Low-performing, high-poverty, public schools notoriously struggle to attract and retain good teachers. This paper studies a setting where independent organizations, including charities and businesses, take over the management of under-performing schools, while funding remains public. Exploiting the staggered expansion of English Sponsor-led academies since the early 2000s, we show that the Sponsor-led takeover leads to substantial changes in the teaching body and the school personnel policy. The probability that the Sponsor appoints a new headteacher doubles upon the takeover, with the new headteacher being, on average, better paid, and more likely to come from outstanding schools. The takeover also induces teacher sorting, with older and lower-achieving teachers leaving the school, and new teachers joining the Sponsor-led school from outstanding schools. Lastly, Sponsors substantially restructure teachers' rewarding scheme and abandon a pay scale entirely based on seniority, leading to a 10 percent increase in pay dispersion across equally experienced teachers.
