Measuring Market Risk Through Entropic Var, Dragomir Nedeltchev, Tsvetelin Zaevski

Mathematical Modelling and Numerical Simulation with Applications

The article aims to measure the market risk beyond the basic risk measures like the Value-at-Risk (VaR) and the Expected Shortfall (ES). The Entropic Value-at-Risk is selected among the available measures based on its advantages -- it is the coherent upper bound of the VaR and ES. This risk measure is applied to the classical Black-Scholes model as well as to some more realistic ones, such as the exponential tempered stable model (the log-returns are presented by a tempered stable L\'evy process), the stochastic volatility model of Heston, its jump extension of Bates, and another stochastic volatility model but with …

From Reclamation To Restoration: Remaking Nature On Portland's Peninsula, Theus Richards

University Honors Theses

This environmental history of the North Portland Peninsula is a critical case study of a landscape in transition, where new "natures" have been constructed through shifting projects of reclamation and restoration. The Port of Portland, who controlled the Peninsula, transformed the marshy bottomlands near the confluence of the Columbia and Willamette Rivers to accommodate greater networks of industrial infrastructure and expand their capacity for global trade. Beginning in 1967, the Port began dredging operations to fill Ramsey Lake to make way for the construction of Rivergate Industrial District. Through this process, Smith & Bybee Lakes were set aside as a …

Protection Vs. Progression: A Macroeconomic Approach To Military Expenditure Direct Effects On Social Outcomes Using Ihdi Measures, Connor Graham

Global Tides

This study examines whether military expenditure reduces inequality-adjusted human development and how national governance quality moderates these effects. Using panel data covering 121 countries from 2010-2023, two-way fixed effects models are employed to estimate the relationship between military spending and the Inequality-Adjusted Human Development Index (IHDI). Three key findings emerge from the analysis based on the resulting data. First, a one percentage point increase in military spending reduces IHDI by 0.0012-0.0015 points. Second, the effects prove seven times larger in developed countries than in developing ones, which runs contrary to expectations and prior literature. Lastly, political stability emerged as a …

The Chainsaw Of Liberty: Reversing The Road To Serfdom Through Empirical Austrian Policy In Argentina (2024–2026), Pedro José Ruíz

SPARK Symposium Presentations

This research analyzes the strategic management of "Social Backlash" risk during the implementation of radical "shock therapy" economic reforms in Argentina. For decades, Argentina served as a cautionary tale of interventionism and hyperinflation; however, the 2023 election of Javier Milei transitioned the nation into a real-world laboratory for Austrian Economic principles. This study examines how the administration navigated the friction of institutional resistance—what F.A. Hayek described as the "security trap"—by prioritizing fiscal responsibility and monetary stabilization.

The analysis leverages 2026 empirical data to demonstrate the efficacy of these reforms. Key findings include a dramatic reduction in annual inflation from 211.4% …

Gender Norms, Socio-Organizational Ergonomics, And Female Labor Force Participation In South Asia, Huma Maqsood, Nor Fatimah Che Sulaiman, Suriyani Muhamad, Nor Aizal Akmal Binti Rohaizad, Sana Mukhtar

The Qualitative Report

Socio-organizational ergonomics encompasses workplace social and cultural factors that influence inclusion, performance, and well-being. Gender-based socio-organizational ergonomics has both microeconomic and macroeconomic implications. In this context, underutilization of women’s economic potential, evidenced by low female labor force participation, emerges as a critical factor that compromises sustainable growth in developing countries. To study the phenomenon, we examined the impact of gender norms on socio-organizational ergonomics and female labor force participation in South Asia. Qualitative data from in-depth interviews with 20 female participants are thematically analyzed using Braun and Clarke’s TA framework. Our findings highlight that socio-organizational ergonomics in South Asia is …

The Buffer Value Of Trade: Quantifying How Global Integration Stabilizes Food Prices And Farm Incomes, Iman Haqiqi, Thomas Hertel

Department of Agricultural Economics Faculty Publications

International trade plays a critical but often underappreciated role in stabilizing global food systems. This study quantifies the buffer value of trade by comparing observed conditions of global integration with a counterfactual restricted-trade world (half trade volume). Using a global market equilibrium model of agriculture combined with a novel randomized yield-shock framework, we evaluate how production volatility translates into volatility in consumer food prices and farm incomes across global regions in 1991–2020. Results show that trade substantially dampens volatility transmission. In the United States, year-on-year volatility in farm income declines nearly threefold under open trade (from 12.1 to 3.9), while …

Offside Trap: African Football As A Mirror Of Global Structural Inequality, Ellen Busolo Milimu

Journal of Global South Sport Studies

Football in Africa, as a legacy of European colonialism, is undeniable. The export of football through colonization resulted in the popularization of the sport while also creating a system of economic exploitation and impoverishment that is the cause of considerable problems for African society. This economic system positioned African  countries as dependents of former colonizers even after achieving independence. Sports, specifically football, provide a unique perspective to explore the no-win     situation in which Africa exists within the global economic system. Always chasing the elusive ‘development’ goal that is dictated by others and shifts without the interests of African countries. The …

The Writing On The Wall: The Rise Of Applied Ai And The Life-Or-Death Choice Every Ceo Must Make Now, Gary Sheng, Ron Roberts

Digital Laboratory: Publisher of Internet Journal

Applied AI is putting AI to its highest and best use: running your organization as autonomously as possible so you can deliver value for humanity while maximizing the scale of the value. The economy is splitting. Organizations that adopt applied AI are expanding their capacity, accelerating their impact, and pulling ahead. Those that don't are quietly becoming irrelevant, not because they're doing bad work, but because the gap between what they can do and what the moment requires is widening every day. This is not a technology question. It is a leadership question. This paper is written for organizational leaders, …

Unpacking Low Glycaemic Index (Gi) Food Purchase Intentions In An S-O-R Framework: The Multidimensional Moderating Roles Of Consumer Knowledge And Trust, Cao Henglei

Student Works (2020-2029)

Research aim: Examine Malaysian consumers’ decisions to purchase low-GI foods using the S–O–R framework, while considering how knowledge and trust shape these decisions. Design/Methodology/Approach: A quantitative survey was conducted among 302 Malaysian consumers, with data analysed via confirmatory factor analysis, structural equation modelling, and moderation analysis. Research findings: Attitudes toward low-GI foods are shaped by health consciousness, environmental concern, and social influence, but not price perception. Purchase intention is directly influenced by trust, with moderation observed only for subjective knowledge. Theoretical contribution/Originality: Extends the S–O–R framework through differentiating knowledge type and clarifying the role of trust in low-GI food consumption. …

How British Toy Company Jellycat Should Manage Demand And Supply-Chain Volatility In An Uncertain Economic Landscape, Ava Heckmann

SPARK Symposium Presentations

Jellycat is a London-based toy company established in 1999 that gained traction during the pandemic as a result of a viral social media craze driven by nostalgia and renewed focus on mental well-being among adults and Generation Z in particular. Jellycat toys became an international sensation–sold in 77 countries worldwide with majority of sales from the United States, China, EU, and the UK (Jellycat, n.d.). Their plush toys are produced primarily in China and Vietnam (Jellycat, n.d.). This unanticipated social media trend caused a spike in demand that the company struggled to match as supply was constrained due to recent …

Restricting Academic Dishonesty At A Japanese University, Joel Weinberg

Japanese Society and Culture

This research explores three approaches to handling academic dishonesty: punitive, preventive, and positive. First, the history of cheating and the punitive approach is briefly discussed. Next, research results of a preventive approach that was used at a Japanese university are given. During this research, three surveys were conducted to gauge students’ opinions about cheating, to account for the methods, and to measure the prevalence of cheating on post-reading quizzes. The survey results show that at least eleven types of cheating on post-reading quizzes were used and that non-cheating students were concerned about this issue. As a result of the surveys, …

Healthcare Decision-Making In An Ageing Society: Legal, Policy, And Ethical Challenges In Japan, Yukio Sakurai

Japanese Society and Culture

This paper examines the evolving landscape of healthcare decision-making in Japan’s rapidly ageing society, with a focus on the legal, policy, and ethical challenges it entails. It analyzes the limitations of the adult guardianship system, the risks associated with family-dependent decision-making, and the underutilization of advance care planning (ACP). The study further considers how demographic shifts, advances in medical technology, and socio-legal inertia affect end-of-life care, particularly for individuals with diminished capacity. A central theme is the inherent ethical dilemma in balancing individual autonomy with Japan's cultural context, where explicit self-assertion can be challenging, especially for older adults. Cultural dimensions …

Institutional Transitions In The Employment Of Foreign Workers In Japan’S Agriculture And Food Manufacturing: From Technical Intern Training To Employment For Skill Development And Specified Skilled Worker In Comparison With The Uk, Tomoyuki Kuwaharada

Japanese Society and Culture

This paper investigates the institutional transition in Japan’s acceptance of foreign workers in the agriculture and food manufacturing sectors, focusing on the restructuring of entry-stage training schemes and their linkage to skill-based employment. In particular, it traces the shift from the Technical Intern Training Programme (TITP) to the Employment for Skill Development (ESD) Programme as the primary entry route, and examines how these institutional changes are embedded within the Specified Skilled Worker (SSW) framework.

Drawing upon official statistics from 2012 to 2024 and sector-specific case studies, the analysis demonstrates that the introduction of the SSW status in 2019 marked a …

A Decade Revealed By Npo Financial Data In A Depopulating Region — Tottori Prefecture, Japan, 2014–2023, Yoshinori Shimosakai

Japanese Society and Culture

This paper examines the quantitative scale, field composition, and financial structure of nonprofit organizations (NPOs) in rural regions experiencing population decline and aging at three levels—the nonprofit sector as a whole, policy fields, and individual organizations—and explores their adaptation and sustainability under demographic change. The empirical setting is certified NPO corporations located in Tottori Prefecture. Drawing on publicly available financial data for fiscal years 2014–2023, the study constructs ratio indicators and per-capita indicators and, in particular, depicts recent trends through a two-point comparison between FY2014 and FY2023 together with a description of year-by-year changes.

The Impact Of Michi-No-Eki (Roadside Stations) On The Regional Economy: An Input–Output Analysis Of Minamiboso City In Chiba Prefecture, Ryusaku Matsuo, Takeru Aizawa, Gon Jan, Wei Yuanxin, Masaharu Uchiyama, Gento Tagami

Japanese Society and Culture

This study quantitatively examines the economic impact of Michi-no-Eki (Roadside Stations) in Minamiboso City, Chiba Prefecture, using an input–output analysis based on the Chiba Prefectural Interindustry Table. Eight Michi-no-Eki were evaluated in terms of direct, indirect, and induced effects, including employment creation. The results show that the total production-inducing effect generated by the stations amounts to ¥7.02 billion per year, and the employment-inducing effect reaches 108.7 persons annually, indicating that Michi-no-Eki function as a central engine of the local economy. Moreover, thematic diversity among stations—such as loquat, flowers, and seafood—enhances multiplier effects through inter-sectoral linkages. These findings demonstrate that Michi-no-Eki …

Employment Contracts, Working Time, And The Well-Being Of Schoolteachers In Japan, Haojun Gong, Shinpei Sano

Japanese Society and Culture

This paper quantitatively analyzes trends in the working hours of schoolteachers in Japan using Teaching and Learning International Survey (TALIS) data from three survey waves. The analysis focuses on differences between fixed-term and permanent employment contracts and on school environment variables, and their relationships with working hours and teacher well-being. Teachers on permanent contracts tend, on average, to work longer hours than those on fixed-term contracts, largely because of greater time spent on administrative duties and extracurricular activities. School environmental characteristics and principal leadership show only weak statistical associations with total working hours. Subjective job satisfaction is lower, and workload …

A Consideration Of Food In A Diversity Society, Masayo Morofushi

Japanese Society and Culture

In recent years, the number of foreign visitors such as tourists and businesspeople, and the number of foreign residents such as workers and international students, have been steadily increasing in Japan. However, the decrease in the number of foreign residents in Japan is relatively small compared to the number of foreign visitors to Japan, due to travel restrictions during the COVID-19 pandemic. Regarding restaurants, Japan has experienced diversity, progress, and cross-cultural understanding; however, these changes have been stagnant due to a decrease in the number of foreign visitors to Japan during the pandemic. Many natural disasters have recently occurred, and …

Exploring The Definition Of Child Poverty : For Consideration Of Legal Policy, Kazuko Ikeya, Fumie Adachi, Kazutoshi Imade

Japanese Society and Culture

We explore the definition of child poverty for consideration of legal policy.

Survey of the actual situation in local governments and private organizations concerning child poverty.

① Some parents don’t know how to prioritize their spending, and there are cases where parents don’t provide for their children.

② This cannot be addressed only with financial investment.

It is inappropriate to define child poverty only by low household income. It should also be

defined as whether children are being provided for through their development.

Converting The Social Security Trust Fund Into A Sovereign Wealth Fund: A Proposal To Secure The Future, Keanu Moore

Dartmouth College Master’s Theses

This thesis proposes the conversion of the Social Security Trust Fund into a sovereign wealth fund (SWF), paired with the phased creation of a mandatory retirement savings system for all working-age Americans. In response to forecasts projecting Trust Fund depletion by 2034, the proposed portfolio shift would diversify assets beyond U.S. Treasuries into global equities, real estate, alternatives, and fixed income, with the goal of enhancing long-term returns while remaining passively managed. While this reform would extend the Fund’s solvency, it is not, on its own, a permanent fix. To ensure structural sustainability beyond the exhaustion date, the thesis proposes …

Bemerge Pop Ups: Social Media Meets Sustainable Fashion, Owen Mehring, Kyla Echols, Avery Edelbrock

SPARK Symposium Presentations

Our research into the online clothing shopping industry has revealed an opportunity to mobilize the strengths of online shopping to build an in-person community. One company we researched, Poshmark, a social, peer-to-peer resale app, uses the strengths of social media to create an online community-based secondhand clothing market. However, one of the largest problems facing society today is the ease of replacing human connection with screen time in today’s world. Online shopping provides convenience, variety, and a larger reach than traditional stores do. However, the human element is often lost. Our company seeks to take the goal of Poshmark to …

U.S. Foreign Aid’S Effects On Un Voting Patterns From Years 2017-2023, Brody Young

Undergraduate Theses

This is a study of the relationship between U.S. Foreign Aid and its effects on a receiving nation’s voting coincidence, with voting coincidence measuring how often a nation votes the same as the U.S. in the UN General Assembly. In this study the dependent variable is voting coincidence in the UN General Assembly. The primary independent variable is the average amount of foreign aid UN nations have received from the U.S. in 2017-2023. With several other more minor independent variables including average GDP of nations from 2017-2023, the average population of a nation from 2017-2023, whether a nation is a …

Identifying Common Trend Determinants In Panel Data, Yoonseok Lee, Peter C. Phillips, Suyong Song, Donggyu Sul

Center for Policy Research

This paper develops a novel method for identifying observable determinants of latent common trends in nonstationary panel data, which are typically removed or controlled in two-way fixed effects regressions. By examining cross sectional dispersion processes, we assess whether panel series exhibit distributional convergence toward specific observed time series, revealing them as long run determinants of the underlying latent trend. The approach also offers a new perspective on cointegration between time series and panel data, focusing on the relative variation of the panel data with respect to the cointegration error. Applying this method to U.S. state-level crime rates demonstrates that the …

Black Swans And Financial Stability: A Framework For Building Resilience, Daniel J. Barth, Stacey L. Schreft

Journal of Financial Crises

This article refines the concept of black swans, typically described as highly unlikely and catastrophic events, to be internally consistent. It explores features of the financial system that prevent the eradication of black swans. The main implication is the need to enhance the financial system’s resilience to withstand unforeseen events rather than focus on past crises. The article introduces a “resilience principle” for designing official-sector policies that can achieve such goals. The principle calls for policies that are adaptable, universal, and systemic. The article provides examples of policies with these features, assuming that the official sector is not better positioned …

Combating Iuu Fishing In The South American Pacific: An Opportunity To Counter Chinese Influence Closer To Home, Alexander E. Goodno

Joint Force Quarterly

A relatively small enterprise that began three decades ago in response to dwindling Chinese squid fisheries, China’s South American distant water fishing fleet has grown exponentially to now number nearly 500 vessels and creates a growing problem for the Pacific coastal nations of South America. By establishing itself at the forefront in combatting illegal, unregulated, and unreported fishing (IUUF) activities off the Pacific coast of South America, the United States can strengthen its role as a leader in the Western Hemisphere and counter growing Chinese influence in South America. This paper will demonstrate how America can achieve this end by …

The Irrelevance Of Filing Speed: Evidence From A Regulatory Reporting Discontinuity, Bryson Mumford

Undergraduate Honors Theses

Does faster financial reporting increase firm value? I exploit the $700 million public float threshold in SEC Rule 12b-2, which imposes a 60-day Form 10-K filing deadline for large accelerated filers relative to 75 days for accelerated filers. Using a fuzzy regression discontinuity design, I show that crossing the threshold sharply increases the likelihood of Large Accelerated Filer status and reduces filing lags by approximately one week, with no evidence of concurrent changes in mandated audit quality. Despite this exogenous acceleration in information disclosure, I fail to reject the null hypothesis that there are no effects on firm valuation (Tobin’s …

Influential Factors In Agricultural Technology Adoption By Maize Farmers In Tanzania: Insights From The 2020–21 National Panel Survey, Rebecca Yauleni, Wiggins Kyatikila, Cornel Joseph

Abstract

In many developing countries, agriculture remains a vital source of food, employment, and income. The adoption of agricultural technologies can boost farm revenue and productivity, reduce food insecurity, and lessen poverty. This study investigates the main factors influencing farmers’ decisions to adopt fertilizers, improved seeds, soil conservation practices, and pesticides in Tanzania. The analysis uses cross-sectional data from the fifth wave of the Tanzania National Panel Survey (TNPS), and employs an ordered probit model. The findings revealed that access to extension services, higher household years of schooling, poor soil quality, livestock ownership, and use of hired labour significantly increase …

Cost-Effectiveness Of Blood-Based Fibrosis Screening In High-Risk Metabolic Liver Diseases With Emerging Therapies, Wanyi Chen, Stephanie T. Chang, Ramsey C. Cheung, Donald B. Chalfin, Kinpritma Sangha, Szu-Yu Zoe Kao, Artem T. Boltyenkov

College of Population Health Faculty Papers

BACKGROUND AND AIMS: Metabolic dysfunction-associated steatotic liver disease (MASLD) remains a global public health threat. With emerging effective pharmacologic therapies, early identification of significant fibrosis in primary care is critical. We evaluated the cost-effectiveness of blood-based noninvasive tests incorporating real-world diagnostic performance in the contemporary MASLD treatment era.

METHODS: We developed a decision-analytic model for MASLD natural history and treatment to compare 6 noninvasive test strategies using Fibrosis-4 (FIB-4) and/or enhanced liver fibrosis (ELF) tests at varying cutoffs. Patients identified with significant fibrosis were referred for hepatology staging (biopsy and/or imaging-based), and eligible individuals were considered for Resmetirom ($47,400/y; mean …
