Parent-Child Information Frictions and Human Capital Investment: Evidence from a Field Experiment Investment

(Conditionally Accepted, Journal of Political Economy )
Abstract: This paper studies information frictions between parents and their children, and how these affect human capital investments. I provide detailed, biweekly information to a random sample of parents about their child's missed assignments and grades and find parents have upwardly-biased beliefs about their child's effort. Providing additional information attenuates this bias and improves student achievement. Using data from the experiment, I then estimate a persuasion game between parents and their children that shows the treatment effect is due to a combination of more accurate beliefs and reduced monitoring costs. The experimental results and policy simulations from the model demonstrate that improving the quality of school reporting or providing frequent information to parents about their child's effort in school can produce gains in achievement at a low cost.

The Risks and Benefits of School Integration for Participating Students: Evidence from a Randomized Desegregation Program

Abstract: Over the last 40 years, efforts to desegregate schools have largely been undone and intra-district programs have limited scope to stem the resulting rise in segregation. This is the first paper to study the short-run and long-run impacts of an inter-district desegregation program on the minority students given an opportunity to transfer to majority-white school districts. Students who are given the opportunity to transfer districts attend schools that are 73 percentage points more white than schools they would have attended. Transferring students have higher test scores, and, over the longer run, an increase in college enrollment by 8 percentage points. At the same time, there is an increase in special education classification and arrests, which are largely for non-violent offenses. Both the benefits and the risks of the desegregation program accrue to male students.

Education for All? A Nationwide Audit Study of Schools of Choice

with Isaac McFarlin Jr.
Abstract: School choice may allow schools to "cream skim" students perceived as easier to educate. To test this, we sent emails from fictitious parents to 6,452 schools in 29 states and Washington, D.C. The fictitious parent asked whether any student is eligible to apply to the school and how to apply. Each email signaled a randomly assigned attribute of the child. We find that schools are less likely to respond to inquiries from students with poor behavior, low achievement, or a special need. Lower response rates to students with a potentially significant special need are driven by charter schools. Otherwise, these results hold for traditional public schools in areas of school choice and high-value added schools.

Better Together? Social Networks in Truancy and the Targeting of Treatment

with Magdalena Bennett (Accepted, Journal of Labor Economics)
Abstract: Truancy predicts many risky behaviors and adverse outcomes. We use detailed administrative data to construct social networks based on students who miss class together. We simulate these networks to show that certain students systematically coordinate their absences in the observed data. Leveraging a parent-information intervention on student absences, we find spillover effects from treated students onto peers in their network; excluding these effects understates the intervention's cost effectiveness by 19%. We show there is potential to use these networks to implement costly interventions more efficiently. We develop an algorithm that incorporates spillovers and treatment-effect heterogeneity identified by machine-learning techniques to target interventions more efficiently given a budget constraint.

Using Predictive Analytics to Track Students: Evidence from a Multi-College Experiment

with Elisabeth Barnett, Beth Kopko and Vikash Reddy
Abstract: Tracking is widespread in U.S. education. In higher education alone, at least 71% of post-secondary institutions use a test to track students, and more than 80% of these institutions use a test as the sole criterion to determine placement. While recent research has shown that tracking can have positive effects on student learning, inaccurate placement has consequences: students face misaligned curricula and must pay tuition for remedial courses that do not bear credits toward graduation. We develop an algorithm to place students that combines multiple measures with predictive analytics. We then conduct an experiment across multiple colleges to evaluate its impact. Compared to colleges’ most commonly-used placement test, the algorithm is more predictive of future performance and substantially increases placements into college-level courses. This is particularly true for English courses and for female, Black and Hispanic students. The algorithm tends to predict pass rates more accurately in math than English.

Simplification and Defaults Affect Adoption and Impact of Technology, But Decision Makers Do Not Realize It

with Jessica Lasky-Fink and Todd Rogers (Organizational Behavior and Human Decision Processes)
Abstract: We conduct a field experiment to understand how enrollment defaults affect the take up and impact of an education technology designed to help parents improve student achievement. The standard strategy schools use to introduce this system to parents—online signup—induces negligible adoption. Simplifying the enrollment process modestly increases adoption, primarily among parents of higher-performing students. Automatically enrolling parents dramatically increases adoption. Automatic enrollment significantly and meaningfully improves student achievement. Survey results suggest that automatic enrollment is uncommon, and that it may be uncommon because its impact is unanticipated by policymakers. Surveyed superintendents, principals, and family engagement coordinators overestimate the take-up rate of the standard condition by 38 percentage points and underestimate the take-up rate of automatic enrollment by 31 percentage points. After learning the actual take-up rates under each enrollment condition, there is a corresponding 140% increase in the willingness to pay for the technology when shifting implementation from opt-in enrollment to opt-out enrollment.

Is Information Enough? The Effect of Information about Education Tax Benefits on Student Outcomes

with Jeff Denning and Day Manoli (Journal of Policy Analysis and Management)
Abstract: There is increasing evidence that tax credits for college do not affect college enrollment. This may be because prospective students do not know about tax benefits for credits or because the design of tax credits is not conducive to affecting educational outcomes. We focus on changing the salience of tax benefits by providing information about tax benefits for college using a sample of over 1 million students or prospective students in Texas. We sent emails and letters to students that described tax benefits for college and tracked college outcomes. For all three of our samples---rising high school seniors, already enrolled students, and students who had previously applied to college but were not currently enrolled---information about tax benefits for college did not affect enrollment or reenrollment. We test whether effects vary according to information frames and found that no treatment arms changed student outcomes. We conclude that salience is not the primary reason that tax credits for college do not affect enrollment.

Leveraging Parents through Low-Cost Technology: The Impact of High-Frequency Information on Student Achievement

with Eric Chan (Journal of Human Resources)
Abstract: We partnered a low-cost communication technology with school information systems to automate the gathering and provision of information on students' academic progress to parents of middle and high school students. We sent weekly, automated alerts to parents about their child's missed assignments, grades, and class absences. The alerts reduced course failures by 28%, increased class attendance by 12\%, and increased student retention, though there was no impact on state test scores. There were larger effects for below-median GPA students and high school students. We sent over 32,000 messages at a variable cost of $63.

The Effects of Making Performance Information Public: Regression Discontinuity Evidence from Los Angeles Teachers

with Matt Hill, (Economics of Education Review)
Abstract: This paper uses school-district data and a regression discontinuity design to study the effects of making teachers' value-added ratings available to the public and searchable by name. We find that classroom compositions change as a result of this new information. In particular, high-scoring students sort into the classrooms of published, high-value added teachers. This sorting occurs when there is within school-grade variation in teachers' value added.

Nudging Technology Use: Descriptive and Experimental Evidence from School Information Systems

(Education Finance and Policy)
Abstract: As schools are making significant investments in education technologies it is important to assess whether various products are adopted by their end users and whether they are effective as used. This paper studies the adoption and ability to promote usage of one type of technology that is increasingly ubiquitous: school-to-parent communication technologies. Analyzing usage data from a Learning Management System across several hundred schools and then conducting a two-stage experiment across 59 schools to nudge the use of this technology by families, I find that 57% of families ever use it and adoption correlates strongly with measures of income and student achievement. While a simple nudge increases usage and modestly improves student achievement, without more significant intervention to encourage usage by disadvantaged families, these technologies may exacerbate gaps in information access across income and performance levels.

Parent Skills and Information Asymmetries: Experimental Evidence from Home Visits and Text Messages in Middle and High Schools

with Chana Edmond-Verley and Nicole Notario-Risk (Economics of Education Review)
Abstract: This paper studies the ability to foster parent skills and resolve information problems as a means to improving student achievement. We conducted a three-arm randomized control trial in which community-based organizations provided regular information to families about their child's academic progress in one arm and supplemented this with home visits on skills-based information in a separate arm. Math and English test scores improved for the treatment arm with home visits. There are large effects on retention for both groups during the year, though learning gains tend to accrue for students with average-and-above baseline performance and students at the lower-end of the distribution appear marginally retained.

Low-cost strategies to empower parents through behavioral science

(Forthcoming, Behavioral Science & Policy)
Abstract: Parents are one of the most powerful determinants of a child's education outcomes. However, behavioral and informational barriers impede parents' engagement with their children. Parenting is complex and limited cognitive bandwidth steers parents' attention away from education investments with long-run returns and toward tasks with immediate returns. Monitoring children is difficult because school-to-parent communication is poor, and parents have inflated perceptions of their child's performance. Poverty exacerbates these problems. This paper shows how the provision of timely, actionable information to parents can attenuate these barriers and improve parental engagement from kindergarten through high school. In particular, providing this information via text message can improve education outcomes at low cost.
