Private Equity IPOs: Long-term Performance and Drivers of Success
by Ignacio Hidalgo Perea
Abstract
In this paper, I explore the impact Private Equity ownership has on portfolio companies post-exit. This thesis aims to add to the discussion of whether the proliferation of Private Equity in the United States is a positive development for the country. Using a proprietary dataset that compiles thousands of IPOs between the years 2000 and 2016, I look at whether there are significant differences in performance between IPOs that come from Private Equity firms and those that go public on their own. Specifically, I use empirical analysis with robust regression to estimate the effects of Private Equity ownership on four key measures of financial success: MCAP growth, Revenue Growth, EBITDA Margin, and EV / EBITDA multiple. By looking at the changes in these measures of performance across three different time windows: 3 years post-IPO, 6 years post-IPO, and 9 years post-IPO, this paper determines how Private Equity ownership affects company performance post-exit and whether those effects persist over time.

Impact of Language Access Laws on LEP Infant Mortality Rates
by Andrew Ryan Griffin
Abstract
Starting with Executive Order 13166 in 2000, the United States federal government
began to address the language disparity issues in health care. Around the same time, several
states have begun to pass language access (LA) legislation mandating translation and
interpretation services at hospitals for limited English proficient (LEP) individuals. This study
uses these multiple discontinuities to evaluate the effect of language access laws on infant
mortality rates, adequacy of care, Apgar scores, and the number of prenatal visits from the years
1995 to 2004 for limited English proficient families. I find ambiguous results of language access
laws positively impacting infant mortality rates or Apgar scores, but I find clear positive impacts
on the adequacy of care and the number of prenatal visits. These findings suggest that language
access laws have a clear effect on reducing barriers for limited English proficient mothers, and
improving the care mothers receive. Furthermore, there is limited evidence that it improves
infant health or outcomes, but the increase of prenatal visits and adequacy of care likely
indirectly leads to improving infant mortality rates and Apgar scores. More research is needed
into discovering how those mechanisms work and the costs of language services.

The Effect of Algae Blooms on Property Values located on Florida’s Indian River Lagoon
by Cameron DeChurch
Abstract
Florida’s Indian River Lagoon has algae blooms that devastate ecosystems, water quality,
and markets for seafood, recreation, and housing. This study estimates part of their economic
impact by examining water quality’s relationship with prices of properties sold near the estuary
from 2007 to 2016. Using water quality scores from 0 to 100, my regression analysis estimates
that one-unit increases in water quality are associated with one-percent increases in sale price.
Upon summing this relationship over all properties in the sample, my paper estimates that these
algae blooms have cost the housing market between $756 million to $3.6 billion.

Bias in Fact Checking?: An Analysis of Partisan Trends Using PolitiFact Data
by Thomas A. Colicchio
Abstract
Fact checking is one of many tools that journalists use to combat the spread of fake news in American politics. Like much of the mainstream media, fact checkers have been criticized as having a left-wing bias. The efficacy of fact checking as a tool for promoting honesty in public discourse is dependent upon the American public’s belief that fact checkers are in fact objective arbiters. In this way, discovering whether this partisan bias is real or simply perceived is essential to directing how fact checkers, and perhaps the mainstream media at large, can work to regain the trust of many on the right. This paper uses data from PolitiFact, one of the most prominent fact checking websites, to analyze whether or not this bias exists. Prior research has shown that there is a selection bias toward fact checking Republicans more often and that they on average receive worse ratings. However, few have examined whether this differential treatment can be attributed to partisan bias. While it is not readily apparent how partisan bias can be objectively measured, this paper develops and tests some novel strategies that seek to answer this question. I find that among PolitiFact’s most prolific fact checkers there is a heterogeneity in their relative ratings of Democrats and Republicans that may suggest the presence of partisanship.

Heterogeneity in Mortgage Refinancing
By Julia Wu
Abstract
Many households who would benefit from and are eligible to refinance their mortgages fail to do so. A recent literature has demonstrated a significant degree of heterogeneity in the propensity to refinance across various dimensions, yet much heterogeneity is left unexplained. In this paper, I use a clustering regression to characterize heterogeneity in mortgage refinancing by estimating the distribution of propensities to refinance. A key novelty to my approach is that I do so without relying on borrower characteristics, allowing me to recover the full degree of heterogeneity, rather than simply the extent to which the propensity to refinance varies with a given observable. I then explore the role of both observed and unobserved heterogeneity in group placement by regressing group estimates on a set of demographic characteristics. As a complement to my analysis, I provide evidence from a novel dataset of detailed information on borrower perspectives on mortgage refinancing to paint a more nuanced picture of how household characteristics and behavioral mechanisms play into the decision to refinance. I find a significant degree of heterogeneity in both the average and marginal propensity to refinance across households. While observables such as education, race and income do significantly correlate with group heterogeneity, it is clear that much heterogeneity may still be attributed to the presence of unobservable characteristics.

After The Mega-Buyout Era: Do Public-to-Private Transactions Still Outperform?
By Bryn Wilson
Abstract
This thesis contributes to existing knowledge of the private equity asset class by examining whether public-to-private leveraged buyouts outperform public peers before and after the mega-buyout era (2005 – 2007). This paper considers the impact of four groups of value drivers on both market- and peer-adjusted returns. These value drivers include operational improvements, leverage, multiple expansion and market timing, and management and corporate decision making. I analyze how these factors change over time, aiming to determine whether public-to-private target firms improve profitability, return on assets, and investment more than peers. I also examine how employment changes at target firms relative to peers. Multivariable regression analysis is used to quantify the impact of operating performance changes, leverage, multiple expansion, credit market conditions, GDP growth, and management and corporate decisions on market- and peer-adjusted returns. The paper constructs a sample of 227 public-to-private transactions from 1996 – 2013 and analyzes 74 transactions with post-buyout financial information available. Results suggest that private equity ownership post-buyout does not lead to significant operational improvements relative to peers, but that improving profitability and ROA are crucial to outperforming the market and peers.

Analysis of the Impact of Gender and Age of Protagonists in Top-Grossing Films from 2000-2019 on Film Success
By Daniella Welton
Abstract
The gender wage gap is prominent in many fields of work, but it is especially prevalent among actors in the film industry. According to the U.S. Department of Labor, as of 2019 female annual workers were earning about 82.3% of their male counterparts. In a study of feature films released from 1980 to 2015, females were making only 56% of their male counterparts on average; this gap also has been shown to increase as female actors get older (Blau & Kahn, 2017; De Pater et al., 2014; Izquierdo Sanchez & Navarro Paniagua, 2017). In this paper I investigate the relationship between the gender and age of protagonists in the film industry and film success through a series of three regressions with film success defined as film total gross, critic reviews, and audience reviews. My data set is composed of 100 top-grossing films from each year 2000-2019. Through my statistical analysis I did not find any evidence that the gender or age of the protagonist influences film success. Thus my results do not show any evidence that the gender wage gap could be related to differences in film success.

Impact of Utility-Scale Solar Farms on Property Values in North Carolina
By Megan Wang
Abstract
The aim of this paper is to investigate impacts of utility-scale solar farms on surrounding property values. Using data from CoreLogic, the Energy Information Administration (EIA), and the US Census Bureau, this study identifies a 12% statistically significant increase in sale values associated with high-income residential homes within three miles of a solar farm. However, low-income homes built near solar farms are associated with a -1.4% decrease in sale values.
As North Carolina continues to expand solar energy, specifically through photovoltaic utilities, understanding the impact of solar development on surrounding communities should be a priority and policies should aim to prevent property devaluations in low-income neighborhoods caused by solar farms.

The Effect of Workforce Participation and Household Income Contribution on Women’s Healthcare Empowerment in Rural Bangladesh
By Hannah Wang
Abstract
Women in Bangladesh have gained increased access to paid work in the past decade yet
still experience limited choices and access to resources, which threatens their ability to exercise
control over healthcare for themselves and their children. Several collective household
bargaining theories hypothesize a link between women’s workforce participation and
empowerment. This paper uses a cross-sectional approach and survey data collected at the end of
a randomized trial field experiment in rural Bangladesh from 2007 to 2017 to examine health
empowerment outcomes for 7,151 young women ages 14 to 32. The results show that women
who work for income are expected to be more health empowered, specifically due to an
increased ability to make their own health decisions. As a woman contributes more income to her
household, her health empowerment is expected to increase, through increased abilities to make
her own health decisions, purchase medicine for herself, and seek medical treatment
independently. Greater mobility and stronger female-positive attitudes towards gender norms are
potential mechanisms through which paid work and household income contribution can translate
into health empowerment. Furthermore, higher total household income, having children, and
being more educated than her husband are expected to increase a woman’s health empowerment.
These results are significant while controlling for the effects of various individual and household
characteristics.
