Bridging the Persistence Gap: An Investigation of the Underrepresentation of Female and Minority Students in STEM Fields
By Aaditya Jain and Bailey Kaston
Prior literature on mismatch theory has concentrated primarily on minority students, whose lower average levels of pre-enrollment preparedness tend to discourage them from persisting in STEM fields as often as their non-minority counterparts at selective universities. Our study shifts the focus to the persistence gap between men and women, invoking social cognitive career theory to investigate how factors beyond preparedness – such as self-confidence – cause women to switch out of selective STEM programs at higher rates than men. Using the High School Longitudinal Study of 2009, we investigate the drivers of STEM persistence for all students and arrive at two main conclusions. First, higher levels of STEM preparedness are more beneficial to STEM persistence at selective universities, confirming mismatch theory in the sample. We then simulate the counterfactual scenario and find that 33% of students at selective schools would have been more likely to persist in STEM had they attended less selective schools, a figure that reaches 50% for underconfident female students. This observation ties to our second conclusion – that underconfidence in math relative to one’s true performance decreases the likelihood of STEM persistence for all students at selective universities, and that female students at selective schools are more likely to be underconfident than their male counterparts. Our findings suggest that the appropriate policy solution to reduce STEM attrition rates among women should then become a two-pronged approach: (1) more selective universities should better support the STEM self-confidence levels of female students, and (2) home environments should ideally cultivate that self-confidence long before women even reach college. In our final set of analyses, we thus explore the factors that drive math overconfidence in the first place, and conclude that both student and parental biases against female STEM ability are detrimental to the STEM self-confidence of female students.

Cashing Out the Benefits: The Spillover Impact of Cash Transfers on Household Educational Investment
By Mitchell Garrett Ochse and Matheus Dias
Using electricity price, generation, installed capacity, and carbon price data from the European Union from January 2015 to December 2018, this study finds that the carbon pricing in the European Union Emissions Trading Scheme (EU ETS) incentivizes electricity sector carbon emission reductions through renewable energy deployment only for economically advanced EU members. Transitional economies show a weak to modest carbon emission increase despite a common carbon price. This study estimates an electricity supply curve, or merit order, for 24 EU ETS members using a Tobit regression model and analyzes changes in this curve using a linear bspline. These shifts provide insight into how carbon pricing affected energy generation, price, and CO2 emissions for two distinct categories of EU member states. The advanced category as a whole saw a strong electricity sector decrease in carbon emissions, both over time and from carbon pricing, while the transitional category as a whole saw a weak increase. This indicates that advanced EU members in Northern, Western, and Central Europe likely sold permits to transitional ones in Southern and Eastern Europe. While these findings may initially reflect the gains from trade of carbon emissions, permits inherent in the European Union Emissions Trading Scheme’s design, the implications of how these two distinct groups have changed electricity generation present challenges to the ultimate long-term goal of EU-wide carbon neutrality by 2050, particularly in transitional economies’ electricity sectors.

The Impact of Violence in Mexico on Education and Labor Outcomes: Do Conditional Cash Transfers Have a Mitigating Effect?
By Hayley Jordan Barton
This research explores the potential mitigating effect of Mexico’s conditional cash transfer program, Oportunidades, on the education and labor impacts of increased homicide rates. Panel data models are combined with a difference-in-differences approach to compare children and young adults who receive cash transfers with those who do not. Results are very sensitive to specification, but Oportunidades participation is shown to be positively associated with educational attainment regardless of homicide increases. Homicides are associated with decreases in likelihood of school enrollment and compulsory education completion; however, they also correspond with increases in educational attainment, with a larger effect for Oportunidades non-recipients.

Analyzing Student and Family-Level Effects on a Family’s Contributions to Fund a College Education
By Justin T. Rosenblum and John H. Zipf
We investigate the efficiency of the current financial aid system for prospective college students. The Free Application for Federal Student Aid (FAFSA) form reviews a family’s financial information and universities review a student’s academic prowess, but neither fully examines students and their family’s qualitative factors such as parents’ highest education level or intended major. Using the National Center for Education Statistics’ National Postsecondary Student Aid Study, we investigate academic, financial, and familial characteristics to determine if they impact a student’s level of private loans relative to their total cost of attendance. We find that students with parents who did not receive a college degree are adversely affected by the current financial aid system. In particular, these students take out a greater amount of private loans relative to their total cost of attendance all else equal. Our finding has wider policy implications; changing the current financial aid system to assist disadvantaged students could help reduce intergenerational education inequalities. In addition, colleges could reach a broader range of students by helping
the students that currently struggle the most to pay tuition.

Measuring the Long-term Effects of Orphanhood
By Nicholas Thomas Gardner
This paper works towards developing the narrative of orphans whose parent or parents died from natural disaster. By taking advantage of the unanticipated nature of death from the 2004
Indonesian tsunami, orphanhood can be treated as much closer to random than similar literature using data centered on HIV/AIDS related deaths. We use a community level fixed effects model to attempt to derive a causal relationship between orphanhood and both education and log wages. Our models suggest that orphaned males aged 14 and older at baseline complete 1-2 fewer years of education than their cohorts. The adverse effects persist in the long-term, as these orphans earn 26% less than non-orphan cohorts.

Protecting Long Term Human Capital in a Financial Crisis: Evidence from the Indonesian Family Life Survey
By Sachet Bangia
The East Asian Financial crisis of the late nineties made its way to Indonesia in January 1998. Using longitudinal data from the Indonesian Family Life Survey (1993-2015), this paper studies the impact of the crisis on education attainment. In the midst of economic upheaval, households with liquid assets at hand, particularly gold, were better able to maintain per capita expenditures. Tracing out the impact of gold ownership on completed education, I find that the effect is most apparent on 7 to 12 year olds in Indonesia. Using within-household variation in completed education, I find that a divergence in the use of gold to protect child education: urban households direct it towards older children, while rural households do the opposite. This result is best understood by considering the effect of the crisis on opportunity costs of schooling. In urban areas, wages declined sharply, while in rural areas, the return to food production increased dramatically. Thus older children in rural areas would be more likely to exit schooling during the crisis, and consequently not benefit from gold ownership in the household. The evidence examined indicates that families sought to protect their children’s long-term human capital, but in households with fewer resources, the children suffered permanent consequences.

Perceptions vs. Reality: School Climate in Miami-Dade County
By Makda Habtom and Yuliya Kozina
This study looks at a sample of Miami-Dade public middle and high schools. The aim is to see if school incidents and perceived safety can be predicted by school-level diversity and other school characteristics. At first, it is found that higher diversity is associated with higher incidents and lower perceived safety. Then, looking at differences over time, it is found that diversity is no longer statistically significant. Instead, increases in school population and free/reduced price lunch over time is significantly associated with an increase in incidents. However, only an increase in the school population is associated with a decrease in perceived safety scores.

The Effect of Federal Regulations on the Outcomes of Auctions for Oil and Gas Leaseholds
By Artur Shikhaleev
This thesis attempts to analyze the impact of the differences in regulatory frameworks that govern state-owned and federally-owned lands on the outcomes of auctions for oil and natural gas leaseholds in the state of New Mexico. The analysis tries to isolate the effect of ownership by controlling for auction structure, leasehold characteristics, and prices of underlying resources. Given past research, the hypothesis is that stricter regulations carry a heavier cost to buyers, so the expectation is that federally-owned leaseholds, which are more regulated, are traded at a discount to state-owned leaseholds. However, the result of this thesis is contradictory to the hypothesis. The conclusion is that stricter regulations do not lead to a discounted auction price for an oil and gas leasehold.

Determinants of SAT Scores in North Carolina
By Abby Snyder
This paper examines the effects of different school and district characteristics on SAT scores across North Carolina from 2007 to 2014. Such characteristics include demographics, poverty and wealth indicators, measures of classroom environment, and achievement levels. A pooled time series panel across districts and schools with fixed effects is used to determine the strength of influence these variables have on scores. Ultimately, this paper identifies which characteristics lead to over– or under–performance relative to predicted values; further, it considers the implications of the SAT being more of an “achievement” test versus an “aptitude” test.

Early Identification of Students at Risk for High School Dropout
By Derek Lindsey
For years, many have hoped to identify why high school students drop out. Typically, studies focus on factors identified in high school or middle school. By tracking a cohort of North Carolina students from third grade onward, we attempt to identify areas for intervention even earlier in order to prevent dropouts. Indeed, we find that variables that can be viewed as indicators of high risk for drop out in middle school are already measurably present as early as third grade. This suggests interventions can begin when students are still very young and when treatment is likely to be more effective.
