Airbnb And The End Of The Local, Nadia Beyersdorf

Theses and Dissertations

This thesis examines how second-home ownership and self-catered tourism reshape community life in Tenby, Wales. While gentrification research often focuses on permanent displacement, less attention has been given to the movement of temporary residents that erodes local culture, social ties, and transforms everyday relationships in coastal towns.

Retroactive Eligibility Waivers: Innovative Or Ineffective?, Mohamed Kacem Benyamine

Theses and Dissertations

Medicaid’s retroactive eligibility provision covers medical expenses for beneficiaries up to 90 days before the application date. Retroactive eligibility insulates uninsured, low-income households from expensive healthcare emergencies. New Hampshire, Arkansas, and Iowa recently obtained waivers to end retroactive coverage. Using a difference-in-differences design and data from the Behavioral Risk Factor Surveillance System, I evaluate whether changes in retroactive coverage affect enrollment rates and self-reported health. Removing retroactive eligibility has no statistically significant effects on insurance enrollment or self-reported health. However, it does increase rates of access to a doctor by 1.0% overall and by 1.6% for women. Removing retroactive eligibility …

The Effect Of Medical Aid In Dying On Health Outcomes And Risky Behavior Of The Elderly, Jacky Wu

Theses and Dissertations

This study examines the effects of Medical Aid in Dying (MAiD) legalization on health outcomes and behavior among elderly U.S. adults using BRFSS data from 2005-2022. Using staggered difference-in-differences, this paper finds that MAiD increases exercise, lowers BMI, and reduces blood pressure medication use.

Cognitive And Economic Development, John Luke Gallup

Economics Faculty Publications and Presentations

A burgeoning literature has found that early childhood health conditions of individuals have large causal effects on their cognitive development, education and earnings. How much does early cognitive development contribute to the national economy? Although researchers have long studied the role of worker health for economic growth, they have not assessed the role of early cognitive development.

Cognitive ability is the foundation of human capital, affecting both educational attainment and economic growth. The risk factors for poor cognitive development are very high in many countries. Each risk factor also causes child mortality, making child survival a viable proxy for good …

Air Pollution And Intimate Partner Violence In India, Siddharth Kishore, Magda Tsaneva, Uttara Balakrishnan

Economics

We combine individual-level data from the Demographic and Health Survey for India with high-resolution spatial data on air pollutants to investigate how exposure to high levels of PM2.5 influences spousal violence. For identification, we use atmospheric wind directions as an instrument for local pollution concentrations. We find that a 10 increase in PM2.5 levels has a statistically significant impact on intimate partner violence, raising the incidence of any violence by 4.7% over the sample mean. Heterogeneity analysis shows the effects are concentrated among rural households and poor households. We also find that air pollution in rural areas is associated with …

Environmental Degradation And Food Systems In Ghana: Gold Mining And Synthetic Pesticides, Da'mirah Vinson

Honors Theses

This research examines the relationship between environmental degradation and food systems in Ghana. Although sociological research has explored how extractive practices like gold mining dispossesses farmers of land (Gilbert and Albert 2016; Agariga 2021; Kwang and Blagogie 2025), the consequences for food sovereignty and security remain understudied. Research that considers food and land from a sociocultural perspective is even more limited. My research addresses these gaps by asking: How do environmental degradation practices—specifically gold mining and chemical use—affect food production, distribution, and security in Ghana? And how does the decline of arable land reshape cultural food identity? To explore these …

Consumer Responses To Ethical And Privacy Concerns In Ai Chatbots: Evidence From Offensive Language, Gender Bias, And Digital Privacy, Jikhan Jeong

Economics Faculty Research & Creative Works

Due to the rapid innovation of artificial intelligence (AI) and big data, AI chatbots have become increasingly influential computational social systems (CSS) in everyday life. However, the expansion of interactions between AI chatbots and consumers has raised significant ethical and privacy concerns. Using data from an online survey, this study empirically examines how consumer concerns about AI ethics and privacy influence their intention to use AI chatbots. These concerns are categorized into three types: 1) offensive language (generated by AI chatbots or users); 2) gender-biased language (from either source); and 3) digital privacy violations. The findings suggest that prior experience …

Beyond Interests And Ideas: Institutions And The Persistence Of Trade Protectionism In Brazil, Samo Sérgio Gonçalves Tosatti

West Chester University Graduate Theses, Dissertations, and Final Projects

Despite decades of economic reforms and growing international integration since the 1990s, Brazil has remained one of the most protectionist large economies in the global trading system. Tariff levels remain relatively high, the country maintains a limited network of trade agreements, and non-tariff barriers play a significant role in shaping market access. Existing explanations for this persistence have focused primarily on the influence of organized interests, particularly import-competing industries, and the enduring influence of developmentalist ideas rooted in Brazil’s import-substitution industrialization (ISI) legacy.

This dissertation argues that these explanations are incomplete without accounting for a third explanatory dimension: institutions. It …

The Impact Of Michigan's Public Act 308 On Foster Care Outcomes: A Synthetic Control Analysis, Maruis D. Martello

Senior Honors Theses and Projects

This paper evaluates the impact of Michigan’s 2014 Public Act 308 on foster care adoption outcomes. By converting traditional adoption subsidies into dynamic, redeterminable contracts, the policy aimed to reduce the financial uncertainty associated with adopting children with latent or evolving special needs. Using data from the Adoption and Foster Care Analysis and Reporting System (AFCARS) from 2000 to 2022, we implement a generalized synthetic control method to account for unobserved time-varying heterogeneity. We find that the policy had no statistically significant impact on the aggregate adoption rate. However, it generated significant gains within targeted subpopulations, increasing the probability of …

Exploring Dominican University Nursing Students’ Perceptions Of Economic Barriers To Accessing Essential Women’S Health Products, Annabelle E. Burke

Nursing | Senior Theses

Period poverty is defined as inconsistent or inadequate access to feminine hygiene products, and it has been shown to negatively impact physical and mental health, academic performance, and dignity across diverse populations. Existing research highlights financial strain, social stigma, and insufficient support as key barriers to menstrual equity among individuals experiencing homelessness, adolescents living in low-resource environments, low-income women, and general undergraduate students (Brinkley & Niebuhr, 2023; Dave et al., 2022; Gruer et al., 2021; Lahme et al., 2018; Parkinson et al., 2024; Gilchrist et al., 2024). However, no studies have examined these issues amongst Dominican University nursing students who …

Fiscal Decentralization, Foreign Capital, And Economic Development In Sub-Saharan Africa, Kwadwo D. Frempong

Theses and Dissertations--Public Policy and Administration

Economic development in Sub-Saharan Africa has been shaped by two transformative policy shifts: widespread fiscal decentralization reforms transferring revenue and expenditure authority to subnational governments, and the pursuit of foreign direct investment to supplement domestic capital. Despite the breadth of these reforms, their effectiveness in promoting sustainable economic development remains empirically contested. This dissertation examines three interconnected questions about fiscal governance and capital flows in Sub-Saharan Africa: what determines the extent to which governments decentralize fiscal authority; how county fiscal composition and revenue autonomy shape subnational economic performance; and how foreign direct investment interacts with domestic investment and growth.

Beyond The Meter: Frameworks For Evaluating The Broad Spectrum Of Microgrid Benefits, Elias Henderson

Cal Poly Humboldt theses and projects

Community-scale microgrids can create a range of social benefits. These include resilient electricity, cleaner air, decarbonization, and economic development, alongside more qualitative values like energy sovereignty and community self-determination. Many such benefits, however, are illegible to California’s market and regulatory frameworks. This thesis traces this disconnect, with particular attention to grid-edge communities in Northern California.

Microgrid benefits are classified as monetized, modeled, or incommensurable according to their inclusion/exclusion in existing regulatory and revenue mechanisms. To explore each category, a mixed-methods analytic approach is employed, pairing Tribal and stakeholder interviews with the development of a microgrid valuation calculator. This tool is …

Labor Market Impacts Of Immigration Enforcement: Evidence From The Second Trump Administration, Rachel Letts

Economics Honors Papers

The onset of the second Trump Administration saw a stark immigration policy shock in the U.S. with record numbers of Immigration Customs Enforcement (ICE) detentions. This paper seeks to understand the labor market impacts of this immigration enforcement that have disproportionately affected the risk of being detained for non-white individuals. To estimate the effect of this policy shock, a triple difference model is used comparing non-white individuals to white individuals living in Metropolitan Statistical Areas (MSAs) with above or below average concentrations of immigration detentions before and after this immigration shock. The regression analysis finds that since the beginning of …

The Economics Of Accountability: Learning From German Holocaust Reparations, Grace I. Gates

Scripps Senior Theses

Drawing on microdata from the Survey of Health, Aging, and Retirement in Europe, this study compares European Holocaust survivors who received reparations with similar Europeans who did not. It finds that, decades on, recipients are not systematically better or worse off on core outcomes like life satisfaction, savings, and debt. This is consistent with the argument that reparations restore parity rather than create new advantages. Where differences emerge, they point to stabilization in more vulnerable settings (e.g., lower likelihood of high debt in parts of Eastern Europe). The main takeaway from effective reparations is applicable to the United States debate: …

Modeling Determinants Of Significant Noncompliance In The U.S. Mining Sector: A Fixed Effects Logistic Regression Approach, Eli Johnson

Dissertations, Master's Theses and Master's Reports

This study examines environmental compliance behavior among mining facilities regulated under the U.S. Clean Water Act (CWA). Using a national quarterly panel of National Pollutant Discharge Elimination System (NPDES)-permitted mining facilities, the analysis evaluates whether local socioeconomic and demographic indicators are associated with the likelihood that a facility enters significant noncompliance (SNC) status. Facility compliance histories are compiled from the U.S. Environmental Protection Agency’s Enforcement and Compliance History Online (ECHO) database and is merged with county- and state-level socioeconomic indicators and election data. A fixed-effects logistic regression model is used to account for time-invariant facility heterogeneity. The results suggest that …

Differential Impact Of Admission Type And Clinical Complexity On Diabetes Hospitalization Costs Among African American And Hispanic Patients In Southeastern Virginia, Ismail El Moudden, Asra Amidi, Reem Sharaf-Alddin, Michael C. Bittner, Qi Zhang

Department of Obstetrics & Gynecology Faculty Publications

Background

Diabetes mellitus (DM) imposes substantial healthcare costs with documented disparities among African Americans and Hispanic patients. To inform care delivery and resource allocation, this study identified hospitalization cost predictors among African American and Hispanic patients with diabetes in Southeastern Virginia.

Methods

We analyzed 6,011 hospital discharges from the Virginia Health Information database (2016-2020) for adults aged 18-85 with diabetes. Discharges were classified by Medicare Severity Diagnosis-Related Groups: DM with complications/comorbidities (DCC, n = 3,328), DM with major complications/comorbidities (DMCC, n = 1,518), and DM without major complications/comorbidities (DWO, n = 1,165). Because cost distributions were right-skewed (skewness 3.5-8.24), we …

But Who Are The Victims? Reassessing The 568 Higher Education Cartel, James V. Koch

Economics Faculty Publications

Thirty prestigious independent American institutions of higher education were at some time members of the 568 higher education group (often labeled a cartel). Seventeen of them were sued by the U.S. Government and representative students who alleged that their meetings and deliberations resulted in collusion that caused students to pay higher prices. Twelve of the seventeen institutions subsequently settled their cases and by 2024 collectively had paid $284 million to do so. However, an inspection of these institutions' pricing reveals that the median 568 Group institution lowered its average real net annual cost to its undergraduate students by 19.07% between …

Partisipasi Pendidikan Menengah Atas Dan Perkawinan Remaja Perempuan 16–18 Tahun Di Indonesia, Herjuno Bagus Wicaksono, Diahhadi Setyonaluri

Jurnal Ekonomi dan Pembangunan Indonesia

This study examines the relationship between upper secondary education participation and early marriage among women aged 16–18 in Indonesia. Using district-level panel data for 2014–2023, the analysis applies a fixed effects regression to estimate the association between the female net enrollment rate and marriage prevalence among adolescent women. The results indicate that higher participation in upper secondary education is associated with lower early marriage rates. Socioeconomic factors and the implementation of the Marriage Law Reform are also relevant contributors. These findings suggest the importance of expanding access to upper secondary education as part of broader efforts to reduce early marriage.

Economic Inequality And Family Formation In The United States, Elizabeth S. Krause

Theses and Dissertations--Economics

This dissertation evaluates economic inequality and family formation in the United States in three essays. In Essay 1, I estimate the effect of providing subsidized access to immediate postpartum contraceptives on birth spacing and infant health among low-income teen mothers. The intent-to-treat estimates indicate a 20% reduction in the monthly short-interval birth rate among teens 12-14 months after policy enactment. I also find evidence that the policy increased the average interval between births and reduced preterm and low-birth weight births and NICU admission rates. In Essay 2, I provide evidence that single mothers and single women without children are important …

The Future Of U.S. Higher Education: Equity Implications Of Shifting Immigration Policies, Research Institute For Social Equity Rise

Research Institute for Social Equity

This report examines the impact of U.S. immigration policies on higher education and international students from 2000 to 2025. It traces five major policy eras, from the post- 9/11 security overhaul and Obama-era expansion to the restrictive turns of 2017–2020 and 2025, and analyzes how shifting regulations have influenced enrollment patterns, economic contributions, and student well-being. Despite hosting more than 1.1 million international students in 2023–2024, the U.S. share of the global student market has fallen from 20% to 16%, underscoring how policy volatility and restrictive measures weaken national competitiveness. Drawing on federal data, scholarly research, and institutional reports, this …

Employment Preferences Of Favela Residents, Mayara Felix, Beatriz Marcoje, Ieda Matavelli, Maria Clara Rodrigues

Cowles Foundation Discussion Papers

We document employment preferences of workers at the margin of informality using open-ended questions and discrete choice experiments in Brazil’s largest favela complex. Stated preferences emphasize pay and tangible job benefits rather than meaning or purpose, while primary complaints center on poor management, customers, and inflexible schedules. Workers exhibit high valuations for all formal sector amenities on average—unemployment insurance, parental leave, and termination notice—as well as for learning opportunities, but lower for non-formal sector amenities such as shorter commutes. Valuations vary systematically by employment sector in ways consistent with sorting: formal workers value formal amenities most, the self-employed value them …

Three Essays In Health Economics, Caroline Andressa Welter

Graduate Theses, Dissertations, and Problem Reports (ETD)

Health outcomes and access to care are shaped by the interaction between public institutions, administrative rules, and responses to health risk. This dissertation investigates how barriers to access, changes in perceived risk, and policy design influence participation in public programs, preventive health behavior, and  treatment continuation. Across three essays in health economics, I examine how individuals respond to disruptions in service delivery, epidemic exposure, and administrative burden, with a focus on vulnerable populations that depend on public systems of care.
The first essay analyzes the impact of Social Security Administration field office closures on participation in federal disability programs during …

Three Essays On Urban Transportation, Daniel Amorim Souza Centuriao

Graduate Theses, Dissertations, and Problem Reports (ETD)

Urban environments are shaped by dynamic interactions between infrastructure development, policy interventions, and episodic demand shocks, all of which can generate unintended externalities in the form of motor vehicle collisions, injuries, and fatalities. This dissertation investigates the determinants of traffic safety in dense urban settings, with a particular focus on how different sources of urban activity affect collision risk and severity. Using New York City as a case study and leveraging high-resolution spatial and temporal data, I examine three distinct but interconnected mechanisms: construction activity, traffic safety policies, and large-scale events.

The first chapter analyzes the impact of urban development, …
