Essays On Health And Immigration Policy, Selen Ozdogan

Dissertations, Theses, and Capstone Projects

This dissertation consists of two essays in applied microeconomics, each examining how individuals and institutions respond to policy changes. Both essays leverage natural experiments and recent advances in difference-in-differences estimation to identify causal effects. Both also speak to a common theme in public policy: the gap between intended and actual consequences of government intervention, and the role that policy design plays in shaping those consequences.

The first essay examines the impact of state-level e-cigarette excise taxes on nicotine and tobacco exposure among adults aged 18 and older. A central contribution is its use of individual-level panel biomarker data from urine …

Cooling Deserts For Renters: Heat Equity Inside The Nyc Housing System, Tahreem Ashraf

Dissertations, Theses, and Capstone Projects

This study introduces the Cooling Desert Index (CDI), a composite spatial measure designed to identify census tracts in New York City where extreme heat vulnerability and structural barriers to adaptive cooling converge. Drawing on five publicly available datasets and a seven phase statistical pipeline, the CDI scores all 2,231 NYC census tracts on a continuous 0 to 100 scale by integrating heat exposure, severe rent burden, household income, racial composition, language access, disability status, and housing crowding. The analysis identifies 557 cooling deserts, defined as tracts where environmental heat risk is high and financial constraints make effective cooling structurally inaccessible, …

Essays On The Economics Of Aging: Structural And Machine Learning Approaches, Alexander S. Kwon

Dissertations, Theses, and Capstone Projects

Population aging has made the study of older workers’ economic behavior increasingly important for understanding labor markets, retirement systems, and public policy. In many advanced economies, rising old-age dependency ratios have increased the need to understand labor-supply, retirement, and savings decisions later in life (OECD, 2025). In the United States, these issues are especially important because Social Security faces long-run financing pressure, with the Old-Age and Survivors Insurance Trust Fund projected to be depleted around 2033 (U.S. Social Security Administration, Office of the Chief Actuary, 2025). Longer life expectancy increases the expected length of retirement and raises the fiscal importance …

Open For Anti-Racism: Assignment Example, Dorina Tila

Open Educational Resources

Economists have scarcely investigated and analyzed the racial discrimination topic despite the prevalent presence of economic racism and inequality in the United States. For example, the article “Race and Racism in Economics” by Cihak, Mlachila, and Sahay (2020) present some shuttering findings. Out of 7,920 articles from the top 10 economic journals published during a decade from 2010-2020, only 0.2 percent cover issues of race, racial inequality, and racism. There is a scarcity of articles analyzing this topic that affects large communities.  However, students need to be exposed to this reality and some unintended consequences of regulations that might aim …

The Effects Of Private Equity Ownership Of Acute Care Hospitals On Patient Experience, Abigail M. Huffman

Theses and Dissertations

In 10 years, private-equity firms' share of hospitals has grown from 2-3% to 8%.  Using data from two sources: the Hospital Consumer Assessment of Healthcare Providers and Systems (HCAHPS) patient surveys and the Private Equity Stakeholder Project (PESP), I demonstrate a causal effect of private-equity ownership on patient satisfaction using difference-in-difference methods.

Initial Type Craft, Micah Angelus

Theses and Dissertations

What kinds of objects can still think when the self-contained aesthetic object can no longer be taken for granted? The historical ruptures that have placed painting under crisis have also brought into view the fallacy of artistic autonomy, raising questions about how value, contemplation, and meaning persist under conditions of deconstruction.

Effects Of Punitive Immigration Enforcement On The Health Of Latinos With Lower Educational Attainment, Andrea Sofia Mendoza

Theses and Dissertations

This paper analyzes the effects of the Secure Communities (SC) immigration enforcement program on self reported health and healthcare-seeking behaviors of citizen and non-citizen Latinos with lower educational attainment. SC allowed local jails to use FBI and DHS data to determine whether arrested individuals were eligible for deportation. SC was rolled out across counties from late 2008 through 2013. Using data from the Behavioral Risk Factors Surveillance Survey (BRFSS) and implementation records from Alsan and Yang (2024), staggered difference-in- difference regression estimates show that SC implementation increased the likelihood of a reported heart attack and heart disease across the sample. …

The Supply-Side Effects Of Air Pollution On Local Non-Polluting Industries, Erin Hyman

Theses and Dissertations

This paper examines the relationship between PM2.5 and the production of goods and services across industries using a county–industry panel (1999–2013). Fixed effects regressions show higher activity in manufacturing but relative declines in non-polluting sectors, suggesting pollution reflects production intensity and a reallocation toward polluting industries.

The Effect Of Inbound Tourism On Consumer Prices In Japan, Serenity E. Thompson

Theses and Dissertations

This paper uses monthly prefectural data to estimate the effect of inbound tourism on Japan’s consumer prices. Results indicate that a 10% increase in foreign overnight stays is associated with a 0.01% increase in capital city prices. The paper discusses localized dual pricing as a response to these price pressures.

The Effect Of Prenatal Substance Use Policies On Women's Well-Being, Zukruf Alam

Theses and Dissertations

This paper examines the effects of punitive and priority treatment policies relating to the use of illicit substances during pregnancy on women's health and health-related behavior. Punitive interventions criminalize substance use during pregnancy, which can even lead to termination of parental rights. In contrast, priority treatment policies support pregnant women and grant them priority access to substance use disorder treatment programs. I use staggered difference-in-differences methods and data from the Behavioral Risk Factor Surveillance System data from 2004 to 2018 to estimate the impact of prenatal substance use policies on women's mental health, physical health, self-reported poor health, and cigarette …

Private Equity, State Enforcement, And Arbitration Outcomes Under The No Surprises Act: Evidence From Air Ambulance Disputes, Peter Readman

Theses and Dissertations

The No Surprises Act (NSA) removed patients from responsibility for out-of-network surprise medical bills. In its place, the NSA established an independent dispute resolution (IDR) process through which providers and insurers submit competing payment offers to an arbitrator, who selects one offer in full. Using the universe of federal air ambulance IDR disputes from Q1 2023 through Q2 2025 (57,368 dispute line items), I examine whether provider ownership structure and enforcement jurisdiction jointly predict arbitration outcomes. The two outcomes, whether the provider offer prevails, and how large that prevailing offer is relative to the benchmark payment rate, the Qualifying Payment …

Congestion Pricing And Traffic Safety: Evidence From New York City, Mirella Charros

Theses and Dissertations

This paper examines the impact of congestion pricing on motor vehicle collisions in New York City. Using a spatial difference-in-differences approach, the study finds evidence of increased collisions near the congestion boundary, suggesting potential spillover effects and changes in traffic patterns following policy implementation.

Air Pollution And Self-Reported Health Outcomes In The United States, Alina Dervisevic

Theses and Dissertations

This study examines the relationship between short-term PM2.5 exposure and self-reported health outcomes among U.S. adults using BRFSS data from 2000 to 2012 linked to county-level pollution and weather data. Results show that PM2.5 exposure is associated with worse mental health and gender specific behavioral responses.

Fascism Usa: Class And Identity Politics In The Age Of Trump, Marc Edelman

Publications and Research

This essay argues that Trump’s triumph in the 2024 presidential contest represents the consolidation of an oligarchical authoritarian project, backed by a multi-class and (surprisingly, for some) multi-racial electorate. It brought intensified state and freelance attacks on immigrants, labor unions, women, LGBTQ+ people, journalists, civil servants, assorted “political enemies,” and other groups that the MAGA movement targets. It is institutionalizing authoritarian governance structures in ways that will be exceedingly difficult to undo. The paper first addresses the experience of growing up in the shadow of fascism. It analyzes various sectors that supported Trump and the impacts of inflation, incumbency, economic …

Opportunities, Challenges, And Conspicuous Absences: An Integrative Review Of The Social Work Literature On Artificial Intelligence, Michael J. Massey, Ian G. Williams, Grace C. Polistina, Eathan A. Breaux

Publications and Research

INTRODUCTION: Social work discourse regarding artificial intelligence (AI) in practice, research, and education has proliferated over the last 5 years, reflecting both excitement over its potential and ambivalence about its ethical challenges. However, the extent to which social work is fully engaging with the structure of AI and its enormous impacts on the environment, labour, and distribution of power remains unclear.

METHODS: An integrative review of social work literature from 2020–2024 was conducted to address two research questions: 1) What is the nature of the social work discourse related to AI? 2) To what extent is the discourse …

Typeface: Machine-Viewing Gentrification On Storefront Imagery In Bedford-Stuyvesant, Brooklyn, Alexander Mcquilkin

Dissertations, Theses, and Capstone Projects

Gentrification—broadly, the replacement of a less powerful group by a more powerful one in an urban context—is oft-discussed in the popular press, but its definition is much-debated in the urban planning literature. Furthermore, academic treatments of displacement understandably focus on measurable yet fairly abstract indicators like changes in rent or income, whereas neighborhood change is often registered by residents on the ground using visual, but difficult-to-quantify markers like retail turnover. This project uses image recognition technology on a set of storefront photos to index the visual streetscape of a neighborhood, as well as to track changes to that portrait over …

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.

All Games Have Equilibria, M. Ali Khan, Arthur Paul Pedersen, Maxwell B. Stinchcombe

Publications and Research

Research on Nash equilibrium existence for infinite games has grown into a patchwork of technical preconditions and counterexamples. This paper presents a unified program in equilibrium theory by revising the predominant model of mixed strategies based on countable additivity. A game is specified by a nonempty set of players and, for each player, a nonempty action set and a bounded von Neumann-Morgenstern utility function. Every such game is shown to admit a Nash equilibrium in finitely additive mixed strategies. In addition, the equilibrium correspondence for any such game is shown to be nonempty, compact-valued, and upper hemicontinuous, and the same …

From Sentiment And Risk To Trade: A Country-Level Study On Geopolitical Trade Effects, Seung Heo

Publications and Research

Can geopolitical risk reshape international trade? I construct directed, monthly measures of bilateral geopolitical risk and its associated sentiment from approximately 5.1 million news articles in the GDELT Event Database, and estimate their effect on trade among eight Asia-Pacific economies at the HS2 product level over 2015--2025, using Poisson pseudo-maximum-likelihood gravity local projections with high-dimensional fixed effects. Pooled across countries, rising risk produces an immediate expansion of trade led by verbal threats and by news tone orthogonal to event content, rather than by material acts, indicating that how a conflict is reported can move trade before the conflict materializes. A …

Latino Economic Inequality In New York City: Income And Snap Recipiency, 2013–2023, Oswaldo A. Mena Aguilar

Center for Latin American, Caribbean, and Latino Studies

This Latino Data Project Report analyzes trends in the economic well-being of Latino households in New York City between 2013 and 2023, focusing on household income and participation in the Supplemental Nutrition Assistance Program (SNAP). The findings reveal a paradoxical pattern: although median Latino household income increased over the decade, economic inequality within the Latino community widened substantially. Income gains were unevenly distributed, with higher-income households pulling further ahead while the lowest-income households experienced stagnation or decline. Over the same period, Latino households fell further behind all other racial and ethnic groups in the city. Additionally, Latinos consistently exhibited the …

Evaluating How New York City’S Recycling And Organic Waste Systems Reduce Resource Waste And Methane Emissions, Zihan Cao

Publications and Research

This study analyzes New York City’s waste management systems, with a focus on food waste diversion, composting, and renewable energy initiatives, to assess their role in methane emission reduction and resource efficiency. The analysis highlights the relative effectiveness of different waste management pathways and suggests that community-scale composting and decentralized anaerobic digestion are associated with substantial methane reductions relative to cost.

Does Idiosyncratic Volatility Follow A Random-Walk? Evidence From U.S. Stocks, Zihan Cao, Ossama Elhadary

Publications and Research

In asset pricing literature, idiosyncratic volatility (IVOL) measures the firm-specific risk that is not explained by broader market movements. In this study, I investigate whether the idiosyncratic volatility (IVOL) of individual stocks follows a random-walk. Using monthly residuals from the Fama-French three-factor model (Fama & French, 1993), I estimate IVOL for more than 11,000 U.S. stocks, and apply the Augmented Dickey-Fuller test (Said & Dickey, 1984) to determine whether IVOL behaves like a random-walk. While most stocks display random-walk behavior, the proportion varies across industries, with some sectors showing deviations from random-walk behavior. Stocks with different levels of average return …

Public approval of unions has reached its highest level in decades, and a new generation of workers is stepping forward as leaders in the movement. The State of the Unions 2025 provides the most comprehensive profile of organized labor in New York City, New York State, and the United States, highlighting where unions are growing, who is leading the charge, and how labor is shaping the future of work …

Intergenerational Transmission Of Health: Evidence From Indonesia, Fatima Khan

Theses and Dissertations

This study estimates the causal transmission of health from mothers to their children. Intergenerational associations in health and other human capital outcomes are well established, but those associations may not be causal due to common unobserved factors between a mother and her child. This study employs two-stage least squares, using weather variation as an instrument, to causally identify the relationship between maternal health and child health outcomes in five dimensions: height-for-age, self-reported health, blood pressure, lung capacity, and hemoglobin levels. The data are from the Indonesian Family Life Survey (1993--2014), a longitudinal survey that provides a 21-year look into the …
