Childlessness And Health In Middle Age And Older Adulthood: Evidence From Singapore, Christine Ho, Dahye Kim, Rohan Ray, Bussarawan Teerawichitchainan

Research Collection School Of Economics

Health and well-being in mature adulthood are important concerns given the prevalence of individuals aging without children. We exploit two new instruments for childlessness— infertility and the number of childless siblings—and condition our analyses on a rich set of covariates including childhood health and financial status, to investigate the causal relationship between childlessness and health in middle age and older adulthood. Using a nationwide dataset of 1,500 Singaporeans aged 50 and above, we show that OLS underestimates the negativeeffects of childlessness on health. We find that childlessness leads to higher likelihood of poorer self-reported health and mental distress. The results …

Uncovering Mild Drift In Asset Prices With Intraday High-Frequency Data, Shuping Shi, Peter C. B. Phillips

Research Collection School Of Economics

Asset prices are commonly represented as a drift-diffusion process, wherein the drift component denotes the anticipated return of the asset within some time frame, while the diffusion component accommodates random shocks. The drift component has substantial practical significance but accurate estimation is typically challenging and has met with limited success in the existing literature except over large time spans. This paper explores a comprehensive range of drift-diffusion models that include constant, linear, trending, and bursting drift. Conditions are identified under which realized squared drift  is a reliable tool for gauging integrated squared drift when the time span Tn is large …

Assessing Ethereum’S Diversification Role With Bitcoin And Major Equity Index – A Bayesian Mixture Copula Approach, Jackie Li, Jacie Jia Liu

Research Collection School Of Economics

With the introduction of spot Ethereum ETFs, Ethereum plays an increasingly important role in the cryptocurrency market. In this paper, we propose a Bayesian modelling framework incorporating a mixture copula for co-modelling Ethereum returns with Bitcoin or FTSE 100 returns. The mixture copula is designed as a combination of the Clayton copula and its three rotations, Frank, and Gaussian copulas. It provides substantial flexibility for handling a variety of dependency structures. The Bayesian approach offers the advantage of jointly estimating both the margins and copulas and simulating future returns in a coherent procedure. Using 10 different risk or risk-return measures, …

Envisioning The Role Of Community-Owned Stores & Aligning Federal Food Policies: A Participatory Approach To Food Security And Food Sovereignty In Sambaa K’E, Denendeh (Northwest Territories, Canada), Narayan Subramoniam

Theses and Dissertations (Comprehensive)

Northern Indigenous communities have relied on traditional food systems for meaningful, nutritious diets since time immemorial. But many Indigenous communities in remote northern regions of Canada still face disproportionately elevated levels of food insecurity due to climate change radically altering the availability for traditional foods, colonial food policies imposing Western diets, and the high costs of transporting store-bought foods. Extreme weather events such as wildfires further isolate fly-in remote communities increasing both the costs of transporting store-bought foods and the difficulties of harvesting traditional foods. There are many examples of community-based initiatives for supporting traditional and locally grown foods, however, …

Multivariate Quantile Autoregression-Mixed Data Sampling (Mvqar-Midas) Modeling Of Cost Of Living And Supply Chain Dynamics In Canada., Patrick Gbolonyo

Theses and Dissertations (Comprehensive)

In recent years, the rising cost of living as a result of persistent inflationary pressures, disruptions in the global supply chains, and changes in the macroeconomic landscape has become a critical topic of discussion. To address this, we move beyond a mean-based framework and employ a quantile regression approach. This allows the persistence of each series and the transmis- sion of shocks between the Consumer Price Index (CPI) (the total CPI which is a percentage change over the past 12 months), the Interest Rate (IR)(the target for the overnight rate), the New Housing Price Index (NHPI), and high-frequency supply chain …

When Prices Spike: Identifying Excessive Volatility In Fertilizer Markets, Feng Yao, Manuel A. Hernandez

Economics Faculty Working Papers Series

Sharp and volatile fertilizer price movements can hinder adoption and reduce agricultural productivity, especially among vulnerable smallholders. Using a nonparametric location-scale approach to model price returns, we quantify the conditional value-at-risk (CVaR) - the high return threshold exceeded with low probability - to identify excessive price spikes in potash, urea, and di-ammonium phosphate (DAP) markets. We use the bias-corrected estimator from Martins-Filho et al. (2018) and propose a simpler estimator based on Hill (1975). Backtesting results indicate superior performance of the Hill-based estimator, supporting its value as a convenient method for detecting unusual fertilizer price surges amid recurring global volatility.

Nonparametric Estimation Of Smooth Coefficients In Fixed-Effect Panel Data Models, Taining Wang, Feng Yao, Jun Cai

Economics Faculty Working Papers Series

We propose a kernel-based nonparametric estimator for a smooth coefficient panel data model with fixed effects. Without requiring a zero sum of fixed effects, we propose an estimator that is easy to construct and computationally efficient. Eliminating the fixed effects through a local within transformation, we perform a local linear estimation for the coefficient functions associated with time varying variables and associated derivatives. We further estimate the intercept coefficient function, if present, through a difference of kernel weighted averages. We characterize the estimator’s asymptotic properties under a large-n and large-T framework. We demonstrate that the estimator is not asymptotically equivalent …

(Wp 2026-01) Du Bois And Veblen's Concepts Of Relative Position: Common Ground Or Stratification Economics And Institutionalist Economics, John B. Davis

Economics Working Papers

W. E. B. Du Bois and Thorstein Veblen employed the concept of relative position. Du Bois' thinking reflects how for Stratification economics people's relative positions explain racial discrimination and segregation. Veblen reflects how for Institutionalist economics people's relative positions explain the role institutions have in the evolution of the economy. Racism in the US marginalized Du Bois' contributions, leaving a divide between his and Veblen's thinking and also between Stratification economics and Institutionalist economics. This has limited the perceived importance of the concept of relative position in economics, leaving it with the 'position-less' asocial individualism of Neoclassical-mainstream economics. This paper …

Do Major Customers Affect Firms' Environmental, Social And Governance Activities?, Feng Dong, John A. Doukas, Stephanie Walton, Rongyao Gloria Zhang, Yiyang Zhang

Finance Faculty Publications

We examine the role of major customers in shaping firms' environmental, social and governance (ESG) practices. We find that firms with major customer relationships undertake fewer ESG activities compared to those without such ties. The association is attenuated when institutional ownership is high, firms are less diversified, customers exhibit greater bankruptcy risk and lower switching costs and during periods of elevated equity market sentiment. Taken together, our findings highlight that reliance on a concentrated customer base can weaken firms’ incentives to engage in ESG practices, with important implications for supply chain sustainability.

International Evidence On The Relationship Between Financial Literacy And Corporate Cash Holdings, Kenneth Yung, Reza Kahibavil, Su Li, Arian Amidi

Finance Faculty Publications

This study is the first investigation of the relationship between corporate cash holdings and financial literacy (FL). We find that a one‐standard‐deviation increase in FL is associated with an 8%–27% reduction in corporate cash holdings, depending on the measure of FL used. Moreover, higher FL reduces the market value of excess cash, indicating that financially literate environments discourage value‐destroying cash accumulation. The results remain robust across alternative definitions of FL and cash holdings, estimation methods, and country subsamples. We further rule out the influence of endogeneity, refinancing risk, and variation in cash needs. Additional analyses identify agency costs as the …

Natural Resource Rents And Energy Poverty Nexus In Next Eleven Economies, Muhammad Salah Uddin, Ayub Ali, Zobayer Ahmed, Md Nasir Uddin Sikdar, Ahsan Habib, Abdullah Elah Al-Mahde

Finance Faculty Publications

Energy poverty (EP) remains a persistent global challenge with important implications for economic development, public health, and social welfare. While natural resources, particularly oil and gas, are often viewed as key sources of energy access, their effectiveness in mitigating EP remains underexplored in emerging economies. This study examines the relationship between natural resource rents (NRR), specifically oil rents (OR) and natural gas rents (NGR), and energy poverty (EP) in the Next Eleven (N-11) countries from 2000 to 2020. The primary objective is to assess how NRR influences EP at various levels of poverty using the Method of Moments Quantile Regression …

How Operational And Disclosure Complexity Shapes The Conglomerate Discount, Feng Dong, John A. Doukas, Son Wilson, Rongyao Zhang

Finance Faculty Publications

This study examines how firm operational diversification and disclosure complexity jointly drive the conglomerate discount. We disentangle disclosure complexity, which is determined by managerially influenced financial transparency, from accounting complexity, which is a direct informational consequence of operational complexity. We find that operational diversification is consistently associated with significant conglomerate discounts, while disclosure complexity independently reduces firm value and amplifies the magnitude of the discount when diversification is high. These findings suggest that transparent disclosures can mitigate valuation costs, offering important implications for managers seeking effective communication, investors assessing complex firms, and policymakers aiming to enhance disclosure quality and market …

Ceo-Employee Pay Ratio Disclosure And Dividend Policy, Rajib Chowdhury, John A. Doukas

Finance Faculty Publications

We examine whether and how the magnitude of the CEO pay ratio affects dividend policy in the context of inequality-averse investors. Our results demonstrate a positive association between the two and remain robust to endogeneity concerns. We find that the CEO pay ratios positively affect dividends irrespective of whether CEO compensation contracts motivate risk-averse or risk-taking policy choices. This non-diverse effect on dividend policy across CEOs with different pay structures contradicts previous studies and highlights the wealth effect resulting from the SEC mandate. Further analyses reveal a negative effect of the pay ratio on cash holdings and investment inefficiency.

The Origins And Expansion Of The Soviet Union’S Military-Industrial Complex, Noah B. Heminger

All Master's Theses

This thesis explores the way in which the “Soviet Military-Industrial Complex” that dominated the Soviet Union’s economy in the latter half of its existence came into existence and what forces caused its expansion. The first force was the ideological and strategic beliefs and assumptions of the leadership and military planners which held that the USSR would always be in existential danger. The second was Stalin’s “Revolution from Above” which broke down the barriers economically and politically that resisted the militarization of politics, economics, and society. And the final force was the stresses of World War II which caused the Soviet …

Financial Literacy And Inclusion Of Philippine Jeepney And Tricycle Drivers, Bryan N. Bernabe, Jyro B. Triviño

Leadership and Strategy Faculty Publications

The study investigated how the different elements of financial literacy influence the financial inclusion of jeepney and tricycle drivers in Caloocan, Metro Manila. Pearson correlation analysis revealed a positive correlation between financial inclusion and attitude, behavior, knowledge, and skills. Additionally, analysis of variance highlighted that education and age play significant roles in enhancing financial literacy. The linear regression findings also supported the idea that income acts as a positive moderator, augmenting the impact of financial literacy on financial inclusion. The study attempted to disaggregate its financial literacy components to understand their impact on financial inclusion, but its interrelationships also require …

Tourism And Quality Of Life In Montana: A Longitudinal Study Of Resident Attitudes 2012-2023, Sophie Morris, Melissa Weddell, Carter Bermingham, Megan Schultz

Institute for Tourism and Recreation Research Publications

Montana’s outdoor recreation and tourism industries have experienced steady growth over the past decade. This report explores how that expansion has shaped residents’ perceptions of tourism. Drawing on data from Montana residents, we track changes in attitudes from 2012 to 2023 on key issues, including overcrowding, the balance between tourism’s benefits and its impacts, quality of life, and the state’s role in promoting tourism.

The State Of Short-Term Rentals – 2024, Elena Bigart, Melissa Weddell, Jesse Wheeler, Sophie Morris, Jenna Asnault

Institute for Tourism and Recreation Research Publications

This report examined the role short-term rentals (STRs) play in Montana’s housing challenges, building on earlier ITRR research (Bigart et al., 2021). Using a mixed-methods approach, the study analyzed STR and housing data from 2019 to 2023 and incorporated interviews with local officials to assess evolving regulations, occupancy patterns, and perceptions of STR impacts. Findings highlight that STRs interact with broader market forces contributing to tight housing conditions and underscore the need for balanced policy approaches that support housing supply and affordability while sustaining tourism-related economic activity.

Monetary Policy And Equity Market Reactions: Linking Monetary Theory To Sector Level Etf Performance, Joseph Freedman

Research Honors

This project examines how the economic framework of U.S. monetary policy translates into financial market outcomes by studying sector level equity responses to changes in the Federal Reserve’s effective federal funds rate. While monetary policy theory emphasizes how interest rates influence investment, borrowing costs and risk taking, financial markets reflect these mechanisms through asset prices. Exchange traded funds provide a useful lens for studying this connection, as they aggregate firm level behavior into tradable sector portfolios.

Using daily data from 2004 to 2025, this study analyzes eleven S&P 500 sector exchange traded funds to evaluate how monetary policy shocks are …

Visit Complexity Differs Between Scarring And Nonscarring Alopecia: A 5-Year Dataderm Analysis, Ian Noel Encarnacion, Noelle Desir, Nicholas Schell, Apoorva Mehta, Temitayo Ogunleye, Susan Taylor

Department of Medicine Faculty Publications

[Introduction] Accurate coding is a critical component of dermatologic practice, influencing reimbursement and documentation of clinical complexity. Although alopecia has significant psychosocial and financial burdens, Current Procedural Terminology (CPT) coding patterns in alopecia management remain largely understudied. Our population-level study using the American Academy of Dermatology's DataDerm clinical registry¹ evaluates alopecia CPT coding trends, pre-2021 and post-2021 evaluation and management (E/M) CPT coding updates,² aiming to inform coding practices and visit complexity, which have significant reimbursement implications.

Dampak Program Pembangkit Listrik 35.000 Mw Terhadap Tingkat Pekerjaan Dan Kemiskinan Di Indonesia, Yohanes Dwi Anggoro, Jahen Fachrul Rezki

Jurnal Ekonomi dan Pembangunan Indonesia

This research analyzes the 35,000 MW Program’s impact on employment and poverty levels in Indonesia using the Callaway and Sant’Anna Difference-in-Differences (CSDID) method. The research uses panel data at the district/city level from 2007 to 2022. The analysis shows the program has a significant impact on reducing poverty, with an average reduction of 5,208 poor people in Model 1; 4,277 people in Model 2; and 4,284 people in Model 3. Based on a subset of regions, the analysis shows the program had a significant impact on increasing the employment rate by 1.2 percent, reducing 16,034 poor people in the Java-Madura-Bali.

Dampak Peraturan Daerah Terkait Kesehatan Terhadap Prevalensi Stunting Tingkat Kabupaten/Kota Di Indonesia, Cakra Yudi Putra, Teguh Dartanto

Jurnal Ekonomi dan Pembangunan Indonesia

Stunting remains a major public health challenge in Indonesia with long-term impacts on health, cognition, and productivity. This study examines whether health-related regional regulations (Peraturan Daerah or Perda) reduce stunting prevalence across 338 districts/municipalities in 2007 and 2013. Using Difference-in-Differences (DiD) and DiD with Propensity Score Matching (DiD-PSM) on secondary data from Riskesdas, Statistics Indonesia (BPS), and the Legal Documentation and Information Network (JDIH), we find no statistically significant causal effect of cumulative health Perda on stunting reduction, although OLS shows a negative association. Sanitation significantly reduces stunting in eastern Indonesia. Findings highlight the need for evidence-based, multisectoral, measurable, implementable, …

The Impact Of Remittances On Food Security In Times Of Crisis—Evidence From Covid-19 In Latin America And The Caribbean, Colin Cannonier

Funded Scholarship

This study examines the association between workers’ remittances and food insecurity in Latin America and the Caribbean using data from a Coronavirus survey covering over 100,000 individuals during the COVID-19 pandemic. Results indicate that receipt of remittances is associated with an 8.8% decrease (2.5% points) in overall food insecurity. Heterogeneous effects are observed among females, individuals in Latin America, and households with children. Remittances from the USA exhibit a stronger influence on reducing food insecurity. The findings underscore the potential importance of remittances in improving food security at both extensive and intensive margins. Policy issues are also discussed.

Bargaining Inefficiency Due To Mispricing Under Incomplete Information : Evidence From The Bilateral Oligopolistic Containership Time Charter Market, Jaeung Cha

World Maritime University Ph.D. Dissertations

A well-established body of bargaining studies theoretically demonstrates that inherent limitations in observing the counterplayer’s private information give rise to an incomplete information setting in bargaining, leading to efficiency losses associated with mispricing, costly delays, and even bargaining failures. As the shipping market, a business-to-business market in which products are generally heterogeneous and the number of both sellers and buyers is limited by high entry/exit barriers, relies on a bargaining mechanism to determine tailored transaction prices, market pricing is prone to inefficiencies associated with incomplete information. However, the relevant empirical evidence remains underexplored in both the shipping finance and bargaining …

Assessing Attitudes Toward Ai Futures: Perceived Likelihood And Policy Preferences, David Chavanne

Economics Faculty Publications

The experiment presented in this paper uses vignettes to measure the perceived likelihood of different AI futures and assess how policy preferences change across these futures. One vignette varies the degree of future AI-driven job loss in a hypothetical scenario set five years into the future, while another vignette varies the degree of future AI autonomy across the same timeframe. Participants provide their perceived likelihood that the world will resemble the scenario in the vignette, and they also express their level of support for either universal basic income (UBI) or a jobs-guarantee program (JG) if the world in five years …

Policy Snapshot : Health Insurance Trends Among Child Care Educators, Sara Amadon

Straus Institute for Thriving Children & Families

This brief compares the health insurance status of child care educators in 2019 and 2024—spanning the COVID-19 pandemic and preceding 2026H.R.1’s implementation—to highlight shifting coverage patterns and state-level solutions to safeguard this essential workforce.

Zero-Sum Thinking, Meritocratic Beliefs, And Preferences For Basic Income And Universal Healthcare, David Chavanne

Economics Faculty Publications

This study uses survey responses to explore how support for basic income and universal healthcare is linked to zero-sum thinking and meritocratic beliefs. Consistent with earlier work, I find that zero-sum thinking and weaker meritocratic beliefs both lead to greater levels of support for basic income and universal healthcare. Using a path analysis, zero-sum thinking is also found to strengthen support for basic income and universal healthcare along two separate channels -- one via zero-sum thinking’s direct effect on policy support and a second via an indirect effect, whereby zero-sum thinking is attached to weaker beliefs in meritocracy, which in …

Essays On Nursing Home Closures And Disparities In Post-Acute And Long-Term Care, Hyeonwoo Do

Electronic Theses & Dissertations (2024 - present)

This dissertation examines the consequences of nursing home closures for access to care, local economic conditions, and resident health in the United States. As the long-term care system shifts toward home- and community-based services and the nursing home sector contracts, facility closures have become an increasingly important policy concern. Although closures may reflect necessary market restructuring in some settings, they may also reduce access, weaken local economies, and place pressure on surviving facilities. Across three essays, this dissertation shows that the consequences of nursing home contraction are uneven and depend on racial and ethnic composition, rurality, local market concentration, and …

Three Essays In Cpi Bias And Health Economics, Auderta Amoako-Nuamah

Graduate Theses, Dissertations, and Problem Reports (ETD)

The first essay estimates bias in the Consumer Price Index (CPI) for elderly individuals in the United States using Engel curve methodology and household-level data from the Panel Study of Income Dynamics (1999–2023). The analysis focuses on how well the CPI reflects changes in the cost of living for older Americans, with particular attention to differences by gender and marital status. Results show that from 1999–2011, the CPI overstated the increase in the cost of living for both elderly and non-elderly households. In contrast, from 1999–2023, the CPI understated cost increases, with the bias generally larger for non-elderly households. Within …

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 …
