Oxytocin, a hormone linked to reproduction and health, may mediate life-history trade-offs across the human life course. Yet, how oxytocin naturally varies with age remains poorly understood. Here, working with the Tsimane, forager-horticulturalists of lowland Bolivia, we collected the largest sample of oxytocin measurements to date (n = 1,242 samples, n = 405 individuals, age = 2 to 84 y, 51% female), and i) examined how oxytocin varies throughout the life course in females and males, and ii) investigated potential drivers of age- and sex-specific variation. Our sample provides rare insight into the relationship between oxytocin and age in a …

Gender Gaps And Economic Growth: Why Haven't Women Won Globally (Yet)?, Patrick Agte, Orazio Attanasio, Pinelopi K. Goldberg, Charles Gottlieb, Aishwarya Lakshmi Ratan, Rohini Pande, Michael Peters, Charity Troyer Moore, Fabrizio Zilibotti

Discussion Papers

Globally women’s labor force participation lags that of men and women, on average, have lower labor market earnings than men. Does economic growth reduce gender disparities in labor market outcomes between women and men? Conversely, do gender inequalities in the labor market impede growth? To inform these questions, we conduct two analyses. First, we estimate regressions using harmonized data on gender gaps in a range of labor market outcomes from 153 countries spanning two decades (1998-2018). Second, we conduct a systematic review of the recent economics literature on gender gaps in labor markets, examining 16 journals over 21 years. Our …

Musculoskeletal Disorders In Dentistry: An Insight Into Dental Techniques And Practices, Mehwash Kashif, Aman Ashar, Amna Rehman, Abdul Aleem, Sidra-Tul-Muntaha Hashmi, Muhammad Yousuf Ali

Journal of Dentistry Indonesia

Objective: Musculoskeletal disorders (MSDs) are common workplace hazards in dentistry resulting from poor ergonomics and static postures, which lead to back, neck, and upper limb (shoulder, elbow, wrist, and hand) problems among dentists, resulting in harm to their health, productivity, and career. This study aimed to assess the frequency of MSDs, risk factors related to MSDs, and awareness of ergonomics among clinicians. Methods: Data were collected from 400 dental professionals, including house officers, postgraduate trainees, general dentists, and teachers/consultants, each with at least 12 months of practice. Data were collected using a structured, closed-ended questionnaire. Before data collection, ethical approval …

Exploring The Relationship Between Entrepreneurial Ambidexterity And Academic Performance: The Moderating Role Of Digital Capabilities: Evidence From Public Universities Of Duhok Governance, Kurdistan Of Iraq, Zeravan Abdulrahman Omar

Arab Economic and Business Journal

This study examines the impact of entrepreneurial ambidexterity, and the synchronization of exploratory and exploitative activities, on academic performance in university departments, and the role of digital capabilities in moderating this impact. Using a descriptive analytical approach, a questionnaire was distributed to 145 department heads at public universities in Duhok Governorate, Kurdistan Region of Iraq. The data were validated using SPSS version 29 and SmartPLS 4.1.1, both of which confirmed the study's hypotheses. The results revealed a direct, statistically significant, positive correlation between entrepreneurial ambidexterity and departmental academic performance. Furthermore, digital capabilities were found to have a significant positive performance-modifying …

Genetically Modified Crops In Africa: Evidence On Adoption, Economic Benefits, Environmental Effects, And Constraints, Aloyce Hepelwa, Innocensia John

Tanzanian Economic Review

Africa faces deep food insecurity with over 300 million undernourished people driven by, low agricultural productivity, and climate shocks. To enhance food production and sustainable development, there is potential seen in genetically modified (GM) crops. To explore the potential of GM crops, this paper examines their production, adoption, economic and environmental impacts, adoption barriers, and policy implications in Africa and globally. This is done using a structured narrative review of peer-reviewed literature, reports, and policy documents (2014–2024) sourced from different databases complemented by stakeholder consultations. The findings show that GM has expanded considerably worldwide driven by high productivity, reduced pesticide …

Reading Between The Lines: The Influence Of Financial News On Investor Decision-Making, Kalia Noble

Honors College Theses

This thesis investigates how financial media narratives shape investor sentiment and short-term market behavior. Drawing on behavioral finance and narrative economics, it examines whether the framing and tone of market news correlate with intraday volatility in the S&P 500 and Dow Jones Industrial Average. By pairing quantitative price data with contemporaneous headlines from major outlets such as Bloomberg, Yahoo! Finance, and CNBC, the study shows that emotionally charged or speculative narratives are closely associated with sharp market swings, even when fundamentals remain unchanged. These findings highlight the influence of media framing on investor decision-making and underscore the importance of financial …

Trading Posts And "Old Pawn": Diné Navajo Trade And The Native Art Industry, Dustin Roberto

Native American Studies Student Publications

"Old pawn" is widely used to describe antique Native American jewelry and goods once pawned for credit at trading posts in the Four Corners region. This article traces how the trading post pawn system influenced Diné Navajo economic life from 1868 through the 1970s, when federal regulators documented exploitative practices such as inflated interest, withheld mail, and items sold without notice. Weavers and individuals pawning jewelry typically received store credit or overvalued commodities instead of cash, a result of the power dynamics of the setting. Today, "old pawn" functions as a marketing label for vintage goods, often without documentation. The …

Can Schools Sustain The Rising Cost Of Retiree Health Care?, Robert Bifulco, Iuliia Shybalkina

Center for Policy Research

Many New York State school districts spend significant amounts each year for retiree health care benefits, and these payments are expected to grow over the coming decades. This brief summarizes findings from a study examining approximately 300 New York State school districts. Unlike retiree pension plans, which are typically prefunded, retiree health care benefits are funded on a pay-as-you-go basis, meaning that benefits for past employees who are currently retired are paid using current district revenues. In the average school district, pay-as-you-go spending currently amounts to 4.5 percent of district revenues. Assuming current benefit and funding policies remain, spending is …

From Cafes To Competitiveness: The Influence Of Amenities On Office Values And Suburban Economic Development In Portland, Or, Jihye Kang

Dissertations and Theses

This dissertation examines the spatial and economic implications of urban amenities in the formation of suburban office markets in the post-pandemic period. The research applies principles from agglomeration theory, spatial econometrics, and urban planning to analyze the statistical relationships between amenity distribution, rent formation, and location behavior across central and non-central submarkets.

The research consists of three integrated papers focused on the Portland–Vancouver–Hillsboro, OR–WA Metropolitan Statistical Area (MSA). The first paper employs spatial econometric modeling, specifically a Spatial Autoregressive Model with Autoregressive Disturbances (SARAR), to examine the relationship between proximity to cafés and office rent levels in Portland’s central business …

Explaining Pension Trends And Recent Pension Performance, Nathan Jeppson, John A. Ruddy, David F. Salerno

Pennsylvania Economic Review

Due to significant unfunded liabilities, many employer-sponsored retirement plans both domestically and internationally are shifting away from defined benefit (DB) pension plans to defined contribution (DC) plans. This is especially the case in private industry. Many expected that the COVID-19 pandemic would cause the funding status of DB plans to worsen. However, the opposite occurred. This is primarily due to decreased life expectancies and improved financial market performance. We utilize a 2004-2021 dataset that contains state level GDP, revenue, pension, and life expectancy data to study U.S. state DB pension plans. We are able to explain over 80% of the …

Housing Burden And Insurance Expenditures, Melanie M. Lytell

Honors Capstones

Housing costs shape the way families spend on protection and security. This study looks at how the share of income devoted to housing, the housing burden, influences household spending on four types of insurance: vehicle, life, personal, and health. Using data from nearly 92,000 households and regression models that account for state differences, I find that even small increases in housing burden shift insurance choices in meaningful ways. A one‑percentage‑point rise in housing burden is linked to a 2.1% increase in vehicle insurance spending and a 0.5% increase in life insurance, but a 0.7% decrease in personal insurance and a …

Hkc02 - Stabilizing Credit When Nonperforming Loans Surge: The Role Of Asset Management Companies, Reiner Martin, Edward O'Brien, M. Udara Peiris, Dimitrios P. Tsomocos

Oberlin College Kasper Economics and Business Working Paper Series

When default losses elevate borrowing costs, expanding credit cannot stabilize the economy because default rates feed back to lending rates through bank balance sheets. Asset management companies (AMCs) break this loop by purchasing nonperforming loans at their long-run recovery values, thereby fixing the effective default rate that banks face. Government purchases of performing loans expand credit but leave this feedback intact. In a model calibrated to the eurozone, the AMC reduces quarterly default rates by 0.8 percentage points, lowers lending rates by 1.6 percentage points, and raises welfare by 0.2%. Government purchases crowd out bank deposits, contracting credit; default rates …

Exploring The Socioeconomic Determinants Of Abortion: Evidence From Pennsylvania, Guido Giuntini, Allyssa A. Wadsworth, Michael A. Malcolm

Pennsylvania Economic Review

Economic factors play a key role in determining fertility and the number of abortions performed. Using detailed county-level data from Pennsylvania, we used fixed-effects analysis to examine how changes in these economic factors are related to the number of abortions. Our most robust estimate suggests that each percentage point increase in the poverty rate is associated with approximately 5 additional abortions per 1000 live births, but that increases in college education rates are associated with a decline in abortions. We also offer some preliminary evidence on the effects of partisanship, religiosity and proximity to an abortion clinic.

Resolving The Energy Efficiency Paradox: Leveraging Benefits For Saudi Arabia’S Building Sector, Fateh Belaïd, Mahelet G. Fikru

Economics Faculty Research & Creative Works

This article examines the economics of energy efficiency in Saudi Arabia's building sector, centering on the "energy efficiency paradox," the observed under adoption of cost-effective technologies despite their clear benefits—such as reducing energy use and associated emissions. We show that a mix of market barriers and behavioral biases—including split incentives, informational gaps, and the value-action gap—constrains adoption of energy-efficient solutions. Recent modeling suggests that improved air-conditioning labels could save up to 80 TWh of electricity annually, though rebound effects may erode some of these gains. Our analysis shows that tackling market failures is necessary but not enough. Strong building codes …

Performance And Policy Review: Does Connecticut’S Open Choice Program Provide Equitable Opportunities To Underserved Students?, Jacob S. Carson, Gazi M. Duman

Pennsylvania Economic Review

The intent of Connecticut’s Open Choice Program is to offer underserved urban students the opportunity to achieve equitable educational outcomes by attending higher-quality public schools. As students transfer to schools that theoretically have more resources, increased educational achievement growth is expected. Additionally, with the implementation of the state exam, Smarter Balanced Assessment, student growth metrics have been introduced in state reporting. Examining student growth is a better measure for school quality than achievement levels. To understand the impact of Open Choice Program, a multiple regression analysis is applied to multiple imputed aggregate data to determine the relationship between school choice …

Hkc03 - Leading A Horse To Water: Understanding The Potential Consequences Of Ordeals In Subsidized Tariff Pricing, Evan Plous Kresch, Carlota Loran Lopez

Oberlin College Kasper Economics and Business Working Paper Series

Water utilities attempting to balance widespread network access with financial stability in providing services often employ Increasing Block Tariffs (IBTs), where volumetric rates increase nonlinearly with water consumed. The widespread adoption of IBTs by utilities across the world is partly attributed to their ability to cross-subsidize smaller monthly users; however, this often leads to the undesirable outcome that large poor households are shifted into higher tariff blocks. To address this, water utilities often adopt a“social tariff”, with significantly lower rates specifically targeted at poor households. However, most of these social tariff policies require households to opt-in or apply to the …

Beyond The Aid Paradigm: Neocolonialism, Recolonisation And The Future For Africa’S Development, John Ringson, Manamela Johannes David Matshabaphala

Southern African Journal of Policy and Development

The persistence of poverty, inequality, and underdevelopment in Africa, despite decades of foreign aid and assistance, has raised fundamental questions about the efficacy and sustainability of the aid paradigm. This qualitative desktop research study, employing discourse analysis, critically examines the complex relationships between aid, neocolonialism, and recolonisation in Africa, exploring the implications for the continent's future development. Drawing on a critical discourse analysis of existing literature, policy documents, and online archives, this study reveals how the aid paradigm has perpetuated neocolonialism and recolonisation in Africa, undermining the continent's sovereignty, agency, and self-determination. The study illuminates the power dynamics and relationships …

Earnings, Ethics, And Fast Fashion: How Does Income Affect Consumers’ Decisions?, Ava M. Minton

All Theses

This thesis examines if annual earnings influence consumers’ likelihood of avoiding clothing brands associated with labor exploitation. To examine this question, the study draws on four major U.S. datasets that together capture two decades of consumer attitudes and self-reported behaviors. The results show that income has a strong and statistically significant effect: household income increases the odds of avoiding exploitative brands by roughly 27 percentage points. Education, ideology, and gender also exhibit meaningful positive associations with ethical consumption, while age slightly reduces the likelihood of boycott participation. Overall, the analysis provides evidence that ethical consumption behaves like a normal good …

Drivers Of Racial Differences In C-Sections, Adriana Corredor-Waldron, Janet Currie, Molly Schnell

Cowles Foundation Discussion Papers

Black mothers with a trial of labor are 25 percent more likely to deliver by C-section than non-Hispanic White mothers. The gap is largest among mothers with the lowest risk and is reduced by only one-fifth when controlling for observed medical risk factors, sociodemographic characteristics, hospital, and physician or medical practice group. Remarkably, the gap disappears when performing a C-section is more costly due to a concurrent pre-labor C-section limiting surgical resources. This finding is consistent with provider discretion—rather than differences in unobserved medical risk—accounting for persistent racial disparities in delivery method. The additional intrapartum C-sections that occur among low-risk …

The "Gray Tsunami": Aging Trends In East Texas, Manuel Reyes-Loya, Cecilia Cuellar, Pedro Gallardo-Toledo

Hibbs Outlook of East Texas

This report examines the “gray tsunami,” the rapid aging of the Baby Boomer generation, and its impact on East Texas. As more workers retire, the region faces a shrinking labor force and a growing elderly population, reflected in a higher old-age dependency ratio than state and national averages. These demographic changes may create challenges for businesses and public services but also open opportunities through workforce flexibility, delayed retirement, and improved planning for healthcare, housing, and transportation. The report emphasizes the importance of proactive strategies to help East Texas adapt to and benefit from this

An Empirical Investigation Of The Effects Of Gunshot Detection Technology In Detroit, Joe Davis

All Graduate Reports and Creative Projects, Fall 2023 to Present

This paper evaluates the impact of acoustic gunshot detection technology (GDT) on crime and policing outcomes in Detroit, Michigan. Leveraging the implementation of ShotSpotter across high-crime neighborhoods, I analyze outcomes including crime rates, emergency calls, police response times, and case clearance. My findings indicate that ShotSpotter installation is associated with a 6% reduction in violent crime but a modest increase in nonviolent crime. The technology also produces a large increase in the reporting of gunfire incidents—over 300% more gunshot-related calls for service—yet police respond 7% slower to ShotSpotter alerts than to citizen-reported gunshots. Consistent with prior research, I find no …

The Relationship Between The Development Of Tourism Special Economic Zones (Sezs) And Local Tax Revenue, Ibnati Misbha Hussudurri, Riatu Mariatul Qibthiyyah

Economics and Finance in Indonesia

This study employs dynamic two-way fixed effect (TWFE) event regressions to analyze the direct impact of SEZ policies, specifically focusing on tourism SEZs in 6 districts across Indonesia and neighbouring districts within the same province. By examining data from 2010 to 2022, the research aims to evaluate how tourism SEZ development influences local tax revenue. Our estimation results show no evidence that Tourism SEZs affect aggregate local tax revenues. However, by type of local taxes, we found that Tourism SEZs have increased hotel tax and entertainment tax but not restaurant tax revenues.

Female Politicians And Corruption In Rural India, Somdeep Chatterjee, Shiv Hastawala, Elisa Taveras

School of Economics and Finance Faculty Publications

This paper leverages random assignment of female quotas for leadership positions on Indian village councils to assess its causal effect on corruption. Since the mid-1990s, India has mandated that at least one third of village council chief positions be randomly reserved for women. Using data from the Rural Economic and Demographic Survey (REDS) 2006, we find that an additional term reserved for a female head as opposed to just a single one reduces both the occurrence and bribe amounts paid to the local government by households. This reduction is also observed in bribes paid to other local officials suggesting downstream …

This thesis investigates the ethno-ecological technologies employed by the Hutsul people within the highland agrarian economy of the Carpathian Mountains. Over centuries, the Hutsuls have developed ethno-ecological technologies that maintain ecological integrity while supporting community livelihoods.

The study addresses three primary research questions: What are the most important ethno-ecological technologies of the Hutsul highland economy? How might these traditional ethno-ecological practices be applied to economic, agricultural, and tourism development in the Hutsul region? How might these traditional ethno-ecological practices be combined with contemporary approaches to encourage sustainable development in the region?

The research explores the devastating impact of the Russian …

Connectedness Of Uncertainty, Volatility, And Stock Market Performance, Szczepan Urjasz

Journal of Banking and Financial Economics

This study examines the dynamic connectedness and spillover effects among various financial and economic indicators, including uncertainty indices, market volatility, and stock market indices, from 3 June 2008, to 30 December 2024. This interconnectedness implies that shocks originating in one market or asset class can rapidly transmit to others, underscoring the potential for systemic risk and financial contagion. The US emerges as a significant net transmitter of influence within the global financial system, with the VIX playing a crucial role in influencing global financial conditions. Major European equity markets also transmit influence, while the Geopolitical Risk Index (GRI) and the …

Intergenerational Transfers In A Tractable Overlapping-Generations Setting, James Feigenbaum, T. Scott Findley, Sepideh Raei

Economics and Finance Faculty Publications

Motivated by the Generation-Skipping Transfer Tax (GSTT) in the United States, we examine how varying estate tax rates by the heir’s age affects welfare. Methodologically, we introduce a parsimonious constant elasticity of substitution (CES) bequest utility that is markedly more tractable than the altruistic specifications commonly used in the literature, delivering closed-form optimal rules and transparent parameterization. Using this new framework, we provide a proof of concept showing how transfers from older to younger generations can enhance equilibrium welfare in a dynamically efficient economy à la Samuelson (1975). We embed the tractable bequest utility in a two-period overlapping-generations model with …

A Capital Idea? The Welfare Effects Of Relocating Indonesia’S Government To A New City, Alexander D. Rothenberg, Radine Rafols, Yao Wang, Yi Jiang

Center for Policy Research

Many developing countries are planning to create new capital cities, a place-making policy designed to alleviate congestion and respond to climate change. To evaluate growth and welfare effects, we specify a dynamic quantitative spatial model with public employment, informality, fiscal transfers, and frictions in trade and migration. We calibrate the model with data from Indonesia and conduct policy experiments studying the creation of Nusantara in East Kalimantan. Despite increasing employment in the new capital region, we find that building Nusantara reduces national growth and welfare. Climate change attenuates its negative welfare effects, but only slightly.

Regulating Privacy Policies On Digital Platforms, Michele Bisceglia, Alessandro Bonatti, Fiona Scott Morton

Cowles Foundation Discussion Papers

We study how privacy regulation affects menu pricing by a monopolist platform that collects and monetizes personal data. Consumers differ in privacy valuation and sophistication: naive users ignore privacy losses, while sophisticated users internalize them. The platform designs prices and data collection options to screen users. Without regulation, privacy allocations are distorted and naive users are exploited. Regulation through privacy-protecting defaults can create a market for information by inducing payments for data; hard caps on data collection protect naive users but may restrict efficient data trade.
