Updated:Parent-Child Information Frictions and Human Capital Investment: Evidence from a Field Experiment
Investment (Revise and Resubmit, Journal of Political Economy)
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.
Successful Schools and Risky Behaviors Among
(forthcoming, Pediatrics. with Mitchell Wong, Karen Coller, Rebecca Dudovitz, David Kennedy, Richard Buddin, Martin Shapiro, Sheryl Kataoka, Arleen Brown, Chi Hong Tseng, and Paul Chung)
This paper studies the impact of a desegregation court ruling on several medium-run outcomes.
This ruling mandates that seven school districts, which serve higher-income, predominantly-white families,
accept a group of minority elementary school students each year who apply to transfer from a nearby,
predominantly-minority school district. The fixed number of slots are allocated to families via lottery.
The offer to transfer increases the number of students who enroll in college by 10 percentage points.
This result is driven by greater attendance to two-year and public colleges and particularly for male students.
There is suggestive evidence male students are also more likely to vote.
In contrast, the offer to transfer increases the likelihood of arrest, most often for non-violent offenses.
This study examines the effect of information about tax credits 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 credits for college and tracked college outcomes. We find that for all
three of our samples---already enrolled students, students who had previously applied to
college but were not currently enrolled, and rising high school seniors---that information
about tax credits for college did not affect reenrollment, application, and enrollment
respectively. We test whether effects vary according to information frames and find
that no treatment arms changed student outcomes. We discuss reasons why we found no
effect and insights into what attributes make low-cost information interventions effective.
Technology Adoption in Education: Usage, Spillovers and Student Achievement
Previous research shows that that providing detailed information to parents about
their child's academic performance can significantly improve student achievement.
Many school districts accomplish this at scale via technology that places student
information online, but the adoption of this technology by parents is unknown.
This paper uses data from a Learning Management System operating in several
hundred schools and a two-stage experiment across 59 schools to study the
adoption of this technology by parents along extensive and intensive margins,
as well as spillovers and effects on student outcomes. A quarter of parents
ever use this technology; adoption follows an S-shape; significant spillovers
occur along intensive but not extensive margins; and student grades improve as a result.
The publication of performance ratings has ambiguous implications for performance. This paper uses school-district data and discontinuities in publication to study the effects of publically rating teachers. Relative to unpublished teachers, we find that high-performing students sort into classrooms with highly-rated teachers. Conditional on publication, ratings labels induce sorting as well as teacher attrition: low-rated teachers teach lower-performing students and are more likely to leave the district in subsequent years relative to higher-rated teachers. There is no effect of publication on test scores and heterogeneous effects by ratings labels that may increase achievement gaps between low and high performing students.
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.
