Abstract

Over-subscription in the school choices is common in developing countries. As
a result, the school choice lottery has become a popular tool to solve the oversubscription
issues. Using a unique user level data from a large mobile platform, we examine the impact of the school choice lottery on the parental educational spending and other consumption and investment decision at China. Our results show that parents respond to the reform significantly after the announcement of the policy. In addition, we find that there exists a large heterogeneity across the gender and migrant history as well as their consumption level. Furthermore, we explore the potential source to finance the increase in educational spending and find that users with low to medium wealth will crowd out the general merchandise spending, but the users with high wealth level will cash out their mutual fund investment. Our results imply that there exists a large magnitude of undocumented noncompliance, which could potentially bias the intended policy effect.

When The Student Becomes the Master: Learning by Creating Math Tutoring Videos

Abstract

Teaching is anecdotally considered a good way to improve one’s own knowledge, but causal evidence of learning by teaching outside of lab settings is sparse. In this study, I conduct a field experiment with 20 middle and high schools in the midwestern United States to test the impact of creating weekly math explanation videos on students’ math skills. I randomized 2,523 students from 128 classrooms to either a “Passive Task”, “Video Creation”, or control condition. Students in both the “Passive Task” and “Video Creator” classrooms were asked to solve a weekly PSAT math problem for 8 weeks. Additionally, the “Video Creator” classrooms were asked to create a video explaining their solution to a hypothetical student. I find that relative to the Passive Task treatment, the Video Creation treatment led to a statistically significant 0.07 SD improvement on the end-of-semester math class grade. Additionally, the Video Creation treatment led to a statistically significant 0.17 SD improvement on the post-test relative to the Passive Task treatment. Further, while both treatments led to a significant improvement for the “exact” task questions subset of the post-test, only the video creation treatment led to a significant improvement on the “other” questions. This shows that the video creation treatment might be particularly effective at helping students generalize what they learn.

Abstract

Economic crises are large adverse shocks to the economy with the potential to reshape labor markets. These events often disproportionately affect some groups of workers. Recent studies highlight the persistent nature of such labor-market scars. Less is known, however, about the behavioral responses to these events, especially among the next generation of workers on the verge of choosing their career paths. Young workers may suffer from information frictions and a lack of networks to effectively navigate the career and job search process. Such frictions could be especially important in turbulent times when uncertainty about labor market conditions increases. We study how students adjust their early career choices in response to economic crises, and how this behavioral response affects their long-run labor market outcomes. We specifically examine the context of the severe recession that struck Sweden in the early 1990s, which disproportionally affected the manufacturing and construction sectors. Our novel empirical strategy addresses correlated unobservables by leveraging the distinctive timing of high school program choices in Sweden, which are typically made when students turn 16, in conjunction with the timing of paternal job loss in heavily affected sectors. As we partial out mechanisms related to paternal job loss in general (e.g. household resource loss or direct effects on compulsory school grades), we interpret our treatment as an information signal stemming from paternal job loss in the crisis-affected sectors. We find that students who experienced paternal job loss in heavily affected sectors were more likely to choose high school programs linked to sectors less impacted by the recession. As a result, these individuals achieved better labor market outcomes in adulthood. Our findings are consistent with informational frictions being a key obstacle to structural change, and we identify career choice as an important mechanism through which recessions reshape labor markets in the long-run.

Inspirational or Demotivational: Experimental Evidence on the Impacts of Role Models

Abstract

Role models with outstanding accomplishments can inspire, yet if perceived as too successful, they might render goals unattainable and minimally influence their role aspirants. Utilizing a randomized controlled trial with Chinese students, this paper contrasts the impacts of “very successful” versus “moderately successful” role models. Comparably, the very successful role models challenge pervasive beliefs about student gender and ability, inspiring girls to believe in their abilities and enhancing their math test scores. Yet, the very successful role models fail to care for students’ subjective well-being and demotivate low-performing boys from aspiring for opportunities beyond their hometown. This paper highlights a trade-off between goal attainability and desirability caused by role models’ level of success. The extent to which students gain from this trade-off differs, based on student gender and ability.

Abstract

A common reason why individuals fail to reach educational and other longterm goals is that it is hard to maintain the required effort over time. One example is the decline in attendance and student engagement over the course of a semester. While educators often attempt to address these issues with information and motivational material at the beginning of a class, or with remedial sessions at the end of the class, we argue that the critical time in longterm sustained efforts falls instead in the middle. To study the effect of timing, we conduct a field experiment that assigns a task aimed at engaging stude nts with the class material at different times throughout the semester. We show that assigning tasks to low-performing students in the middle of the term, compared to early or late in the semester, improves their performance along several dimensions: attendance, homework grades, and exam grades. Consistent with our theoretical framework, our findings suggest that accumulating frictions over the course of a semester and the corresponding decline in effort can be addressed by an intermediate timing of costly "engagement'’ tasks.

Overconfidence and Inaccurate Self-Assessment: Evidence from Student Grade Estimations

Abstract

We conduct a series of surveys in the 12th grade of a senior-high school in China for a cohort of around 1,800 students who took the annual National College Entrance Exam (also known as Gaokao) in July of the years 2022 and 2023. Students were asked to fill in multiple surveys for five sets of mock exams and Gaokao: one before each exam, and the other after the exam but before the exam results are revealed.

Using over 1,300 students’ self-reported estimations of their exam performance on six different subjects, we find stronger effects of overplacement (of their ranks) than overestimation (of exam scores) for the same task, following the definitions of overconfidence in Moore and Healy (2008).

In estimates of the current task (of mock exams), we also confirm the Dunning-Kruger effects that students who are more competent in a subject are less likely to overestimate or overplace their performances. Such Dunning-Kruger effects are stronger for overplacement than those for overestimation, and are more profound in the before-exam surveys than those in the after-exam ones. However, the same analyses in estimates of a future task (of Gaokao) present mixed results.

To further understand these new findings, we decompose the traditional overconfidence measures into two separate perspectives: biased estimates (measured by the signs of the estimation errors), and inaccurate self-assessments (measured by the absolute value of the estimation errors). We show that, in estimates of the current task, both perspectives contribute to the Dunning-Kruger effects: students who are more competent in a subject are less likely to overestimate (or overplace) their performances and have more accurate self-assessments. While taking the survey after the exam does not significantly change the biased estimates effects, it does help reduce the gap in self-assessment accuracy between students with different competency.

The Effect of Losing Pell Grant Eligibility on Student Outcomes

Shinyoung Kim

Abstract

This paper examines the effects of Pell Grant eligibility on student outcomes using a regression discontinuity (RD) design and bounds treatment effects to account for selection effects arising from the loss of Pell Grant eligibility- a question unexplored in previous research. While initial eligibility is determined by financial need, students must achieve Satisfactory Academic Progress (SAP) to retain the grant. The findings show that students who initially received more grant aid are 26 percentage points less likely to persist in the year they lose Pell and 8 percentage points less likely to graduate within 4 years compared to those with less aid. Moreover, those who did not persist had significantly lower SAT math scores, suggesting that non-persistence is not random; thus, the RD estimand is confounded by selection effects. Finally, I estimate bounds on the treatment effects, accounting for selection effects. The bounding results suggest that the previously estimated effects of additional grants on student outcomes may be underestimated. For example, while naive RD estimates find no effect on 4-year graduation rates, accounting for selection effects reveals that students receiving additional grant aid are 7 percentage points more likely to graduate within 4 years compared to those with less aid. One may argue that the SAP policy enhances aid efficiency by pushing out students whose costs of finishing college exceed the benefits; however, evidence suggests that it also dismisses students who may be capable of completing and potentially benefiting from college.

Abstract

This study evaluates the impacts of being assigned to a STEM- versus humanities-focused high school curriculum. We use a regression discontinuity design, exploiting admissions cutoffs generated by a centralized assignment system in the country of Romania. We obtain outcomes using both administrative data and large-scale surveys. We examine effects on test scores, college-going, expectations, non-cognitive outcomes, and social and economic preferences. We find that being assigned to STEM causes students to think they are better at STEM, to like STEM more, and to be much more likely to study STEM in college. In addition, it does not appear to adversely affect wellbeing or social connections. Effects are similar by gender and by initial curricular preferences, suggesting that additional high school exposure to STEM may have widespread benefits.

Abstract

Bridging the gender gap in STEM fields has emerged as a concern for policymakers both in developed and developing countries. This paper examines the impact of light touch intervention where female engineering students act as role-models for high school students in Peru. We find that a brief 20-minute interaction with the role-models led to sharp increases in preferences towards engineering, with the effects being concentrated on female students with high math aptitude. We find that these results are driven by increased self-confidence as a result of exposure to role models. Set in the context of a developing country, our results show that low-cost interventions can be helpful in reducing the STEM gender gap but cannot address broader deep seated gender stereotypes.

Abstract

We propose a new strategy to identify the impact of class rank, exploiting a “visible” primary school rank from teachers’ exam grades, and an “invisible” rank from unreported standardized test scores. Leveraging a unique panel dataset on Italian students, we show that the visible rank has a substantial impact on students’ perceptions, which affects subsequent academic performance. However, the effect of being surrounded by higher-SES or higher-achieving peers remains positive even accounting for the decrease in rank. Higher-ranked students self-select into high schools with higher average student achievements. Finally, exploiting an extensive survey, we identify psychological mechanisms channeling the rank effect.
