Engaging The Audience Through Gps: Using Ai To Design Experiential Learning Activities In The Social Sciences, Zaki Eusufzai

Economics Faculty Works

Shows how instructors can use AI tools to design experiential learning activities that promote deeper engagement and critical thinking. Introduces the GPS framework— Games, Puzzles, and Storytelling—as an alternative to traditional assessments. A game on social mobility shows how AI-assisted design can produce meaningful classroom simulations that reveal structural inequality and foster reflection. Rather than being a threat, AI can be re-purposed as a creative partner in re-imagining pedagogy.

The Trade-Off Between Quality And Quantity: Evidence From A Field Experiment On Tutoring, Rohen Shaw

Cowles Foundation Discussion Papers

High-dosage tutoring has the potential to substantially raise adolescent academic achievement, but schools may lack the resources to deliver small-group tutoring frequently at scale. This paper studies the relative importance of tutoring group size (quality) versus tutoring frequency (quantity) using a randomized controlled trial in a Midwestern U.S. charter middle school. Students were randomized to a control group, tutoring twice a week in 2-student groups, or tutoring three times a week in 3-student groups, with equal total cost per student across the two treatment arms. The results show that tutoring in 2-student groups led to a statistically significant improvement in …

Hubungan Pertumbuhan Ekonomi Dengan Inflasi Di 90 Kabupaten-Kota Indonesia, Samsul Arifin, Hermanto Siregar, Lukytawati Anggraeni, Yeti Lis Purnamadewi

Jurnal Ekonomi dan Pembangunan Indonesia

This study aims to explain the relationship between economic growth and inflation in 90 Indonesian cities during the period 2018–2022 using the GMM estimator with Windmeijer - Sigmund robust standard errors. The author’s findings reveal that the two-way relationship between the two is that economic growth has a significant positif effect on inflation, while inflation has a negatif but insignificant effect. Through the results of this study, policymakers and stakeholders can consider priority objectives, namely achieving economic growth targets compared to inflation problems during the COVID-19 crisis and economic development during the future economic recovery.

Dampak Kebijakan Hilirisasi Nikel: Kuasi-Eksperimen Di Sulawesi, Siddiq Robbani, Uka Wikarya

Jurnal Ekonomi dan Pembangunan Indonesia

Studi ini menganalisis dampak kebijakan larangan ekspor bijih nikel (2014–2016) dan pembangunan smelter (2009–2021) terhadap PDRB per kapita dan konsumsi rumah tangga per kapita menggunakan data panel seimbang dari 81 kabupaten/kota di Sulawesi periode 2006–2021. Dampak kausal dan efek spillover dianalisis menggunakan metode Difference-in-Difference (DiD) dan Spatial Durbin Model (SDM). Hasil penelitian menunjukkan kebijakan larangan ekspor tidak berdampak pada kedua variabel. Pembangunan smelter justru berdampak negatif terhadap PDRB per kapita, tetapi menghasilkan efek spillover positif pada PDRBperkapita daerah tetangga dan efek spillover negatif terhadap konsumsi rumah tangga per kapita di daerah non-smelter.

Entropic Foundation Of Finance And Physics: Securities Price Dynamics And Quantum Theory, Mohammad Abedi

Electronic Theses & Dissertations (2024 - present)

In many scientific and financial contexts, we must reason and make predictions under conditions of incomplete information. This dissertation develops Entropic Dynamics (ED) as a unified framework for deriving dynamical laws directly from principles of inference. Within this approach, probability distributions represent states of knowledge, and their evolution is determined through entropy maximization subject to relevant constraints. This leads to a novel concept of entropic time and a formulation of dynamics as an inferential process. In this talk, I will present how ED provides a common foundation across multiple domains. In physics, quantum dynamics for particles and scalar fields in …

From Coverage To Care: Evaluating The Effects Of Aca Medicaid Expansion On Birth Outcomes, Bailey R. Lengfelder

Economics Honors Projects

I examine the impact of the Affordable Care Act’s Medicaid expansion on maternal and fetal health outcomes using National Center for Health Statistics Natality data from 2006 to 2023. I exploit staggered state adoption as a quasi-experiment, and the staggered differences-in-differences estimates indicate an increase in the share of Medicaid births but broadly no impact on maternal prenatal care, maternal health, and fetal health. The absence of statistically significant effects is consistent across heterogeneity groups. These null findings indicate that expanded insurance access through the Affordable Care Act may be insufficient to improve health outcomes. I do find a statistically …

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 …

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.

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.

Testing Mean Stability Of Heteroskedastic Time Series, Violetta Dalla, Liudas Giraitis, Peter C. B. Phillips

Research Collection School Of Economics

Time series models are often fitted to the data without preliminary checks for stability of the mean and variance, conditions that may not hold in much economic and financial data, particularly over long periods. Ignoring such shifts may result in fitting models with spurious dynamics that lead to unsupported and controversial conclusions about time dependence, causality, and the effects of unanticipated shocks. In spite of what may seem as obvious differences between a time series of independent variates with changing variance and a stationary conditionally heteroskedastic (GARCH) process, such processes may be hard to distinguish in applied work using basic …

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 …

Understanding Housing Market Adjustment: Evidence From Population Shocks, Regulation, And Monetary Policy, Michael Tyler Duncan

Graduate Theses, Dissertations, and Problem Reports (ETD)

This dissertation studies how housing markets adjust to demographic shocks, local regulation, and macroeconomic policy through three related essays. Chapter 1 develops a dynamic stochastic general equilibrium (DSGE) model and panel VECM evidence to study how population volatility affects housing prices, rents, and construction. It finds that population shocks generate strong price responses across housing markets and more pronounced effects in tight housing markets and declining regions. Chapter 2 examines local rental registry policies using county-level difference-in-differences analysis and finds limited aggregate effects but meaningful heterogeneity across treatment intensity and market segments. Chapter 3 revisits the macro-housing VAR literature on …

The Impact Of Student Achievement On Economic Growth: A Pisa-Based Analysis Of Gdp Per Capita, Emma Rose Nasr

Undergraduate Theses and Capstone Projects

This study investigates the extent to which international student achievement, measured through PISA assessments in mathematics, reading, and science, explains cross-country differences in economic development. Using an unbalanced panel data set combining PISA results from 2015, 2018, and 2022 with macroeconomic indicators from the World Development Indicators, I estimate multiple regression models, including pooled OLS, country and time fixed effects, and subsample analyses for developed and developing countries. Results from the pooled model indicate strong positive associations between PISA scores and GDP per capita, consistent with human capital theory. However, these relationships diminish under fixed effects specifications, suggesting that cross-country …

The Effect Of The Affordable Care Act Medicaid Expansion On The Risk Of Hospital Closure And Adolescent Hpv Immunization In Rural Counties, Juliette Des Rosiers

Scripps Senior Theses

From 2005 to 2025, over 200 rural hospitals shut their doors, often citing increased operational costs, staffing shortages, low patient volume, regulatory barriers, financial challenges exacerbated by the COVID-19 pandemic, and uncompensated care as common contributors to the closures. Rural patients are often referred by their primary care physician to a hospital for regular immunizations, since smaller clinics have less capacity to provide immunizations due to a shortage of pediatricians and limited vaccine stock. A crucial vaccine that is not required by schools and underutilized in rural areas is that against human papillomavirus (HPV), a virus that infects cutaneous and …

Three Essays In Labor Economics, Yoritsugu Shimazu

Electronic Theses & Dissertations (2024 - present)

The first chapter decomposes aggregate productivity growth into a pure-technology contribution and an allocative-efficiency contribution for Japan and the United States, applying a single estimation methodology symmetrically to comparable firm-level panels. Production functions are estimated by the Gandhi, Navarro, and Rivers (2020) gross-output procedure under monopolistic competition (GNR-MC), which recovers firm-level price markups and wage markdowns, and these enter the Baqaee–Farhi (2020) decomposition through the closed form of Aoki et al. (2024). Both panels are drawn from Compustat with identical pre-processing and estimation, and we close the markup-level identification gap that GNR leave open with a normalization anchored on the …

Dynamic Effects Of Economic Shocks Under Uncertainty, Seojin Jung

Electronic Theses & Dissertations (2024 - present)

This dissertation studies the dynamic effects of economic shocks under uncertainty across three self-contained essays.

The first essay introduces a two-stage model averaging estimator for impulse response functions that flexibly combines local projection (LP) and vector autoregression (VAR) methods, as well as different statistical paradigms (Bayesian or frequentist). In the first stage, we compute weights within the LP and VAR groups. A second-stage weight then integrates the two groups by accounting for their structural differences and incorporating their respective strengths. Monte Carlo simulations illustrate a typical bias-variance trade-off: LP-based estimators tend to exhibit lower bias, whereas VAR-based estimators display lower …

(En)Gendering Capacity: Neoliberalism, Empowerment, And Responsibility For Women In The Un’S Capacity Building Agenda, Sabrina K. Harris

Emancipations: A Journal of Critical Social Analysis

This article analyzes how the UN constructs capacity building as an element of its development agenda. It theorizes that the UN operates as a governmental actor, adopting and pursuing a political rationality of good governance, while also navigating structural limitations to its organizational authority in implementing this agenda imposed by the liberal international order. As such, this article argues capacity building emerges as a valuable technology of development for several reasons: firstly, it operates as an individual-level intervention, circumventing UN limitations on authority in mandating state action, and secondly, it is framed as demand-driven and empowering while delivering on the …

Maximizing Online Intersession Enrollment Through Targeted Course Offerings, Heather S. Mcmillan, Charles D. Mcallister

Journal of the North American Management Society

Abstract

Online winter intersession courses have become an increasingly important strategy for universities seeking to support accelerated student progression while generating incremental tuition revenue. This study examines ten years of winter intersession enrollment data from a public, master’s-level comprehensive university in the Midwestern United States to identify course characteristics associated with higher student enrollment. Using 12,520 individual enrollment records, the analysis focuses on course type (general education versus major requirement), course classification (lower level, upper level, blended undergraduate/graduate, and graduate), and course discipline. A series of ANOVAs and Bonferroni post-hoc tests reveal significant differences in enrollment across these dimensions, with …

Organizational Pitfalls Of The Dual-Identity Leader, Yvonne Randolph, Asa Wilson

Journal of the North American Management Society

The dual-identity leader (D-IL) is an individual assigned to one job description yet is, in practice, fulfilling an additional position’s role. This secondary role is self-determined; has not been assigned yet is being allowed by those with governance and/or executive authority. Three case examples of the D-IL are presented and discussed as a problematic leadership configuration for an organization. The personal characteristics driving this approach are identified as a foundation for clarifying the organizational consequences of such an executive leader. Preventative and corrective tactics are discussed that eliminate or minimize the adverse impact of the D-IL’s organizational behavior.

The Problem With The Mode Of External Debt Servicing: The Case Of Nigeria, Shehu Tijjani Muhammed

Bullion

This study empirically tested the hypothesis that external debt servicing leads to debt accumulation using Nigeria as case study. The method employed combines logic and debt stock variation analysis. Results indicate that Nigeria has served interest on its external debt only to see its external debt stock increasing confirming the hypothesis. A reform is needed to enable the country retain the domestic income lost to international speculative capital to boost government revenue. A sovereign agency to intermediate between the indebted residents, exporters, and the banking system can be created to solve the problem.

The Role Of Linear Programming And Sensitivity Analysis In Improving The Transportation And Distribution Of Vegetable Oils: A Case Study Of The State Company For Vegetable Oils In Iraq, Zainab Alaa Hameed

Muthanna Journal of Administrative and Economics Sciences

The State Company for Vegetable Oils in Iraq faces a fundamental challenge of high transportation costs and inefficiency in distributing products across factories and warehouses to meet growing demand. Accordingly, this study aims to employ operations research methods-specifically linear programming and sensitivity analysis---to design a distribution plan that enhances efficiency and minimizes costs. The methodology involved developing a mathematical model of the transportation problem based on actual data related to supply quantities, demand requirements, and transportation costs between production sources and distribution outlets. The model was solved using WinQSB software to determine the optimal solution. Sensitivity analysis was then conducted …

The Conditional Nature Of The Value Premium: Interaction And Cross-Sectional Evidence Across Market Regimes, Samuel L. Klein

Honors Thesis

This thesis examines why value-based investment strategies generate strong returns in some environments yet weaken or collapse in others. Regressions test whether the performance of the book-to-market ratio depends on the investor’s perception of financial health as defined by F-Score and accruals. Across additive regressions, interaction models, cross-sectionals, and heatmap visualizations, a consistent mechanism emerges. The book-to-market effect is strongest when financial information is neither highly reliable nor severely distressed. In these “moderate-quality” environments, investors struggle to fully distinguish the transitory components of earnings from their persistent counterparts. This makes valuation ratios particularly influential. Accrual intensity and financial strength jointly …

Effects Of External Debt On Inflation In The West African Monetary Zone (Wamz), Collins Anosike

Journal of Global Awareness

This research examined the effect of external public debt on inflation in the West African Monetary Zone (WAMZ) using annual data from 1960 to 2022. The study selected the six member countries of WAMZ, namely: Gambia, Guinea, Nigeria, Sierra Leone, Liberia, and Ghana, to examine their economic well-being, growth performance, external debt, and inflation over a 63-year period. This study is unique because it examines three periods, namely: pre-WAMZ (1960 to 2000); during WAMZ (2001 to 2022); and the entire period (1960 to 2022), extends previous studies by using updated data, and then shows the long-run positive effect of external …

Reconsidering The Introduction To Interest Rate Theory

Journal of Economics and Finance Education

The various theories of interest rate determination presented in economics textbooks each spotlight a particular fundamental force behind the equilibrium rate. Unfortunately, each theory’s successful emphasis of one determinant of the interest rate comes at the cost of distorting some other aspect of its determination. This paper argues that the basic market analysis of debt securities (e.g., bonds and commercial paper) left out of most macroeconomic as well as money and banking textbooks provides a straightforward and practical perspective on interest rate determination that can help students navigate the established interest rate theories.

Replacement And Reputation, Navin Kartik, Elliot Lipnowski, Harry Pei

Cowles Foundation Discussion Papers

Does electoral replacement ensure that officeholders eventually act in voters’ interests? We study a reputational model of accountability. Voters observe incumbents’ performance and decide whether to replace them. Politicians may be “good” types who always exert effort or opportunists who may shirk. We find that good long-run outcomes are always attainable, though the mechanism and its robustness depend on economic conditions. In environments conducive to incentive provision, some equilibria feature sustained effort, yet others exhibit some long-run shirking. In the complementary case, opportunists are never fully disciplined, but selection dominates: every equilibrium eventually settles on a good politician, yielding permanent …

Oxytocin Varies Across The Life Course In A Sex-Specific Way In A Human Subsistence Population, Abigail E. Colby, Dominik C. Jud, Valerie Baettig, Jordan S. Martin, Camila Scaff, Michael D. Gurven, Benjamin C. Trumble, Bret A. Beheim, Paul L. Hooper, Daniel K. Cummings, Hillard Kaplan, Jonathan Stieglitz, Arnulfo Cary Ista, Adrian V. Jaeggi

ESI Publications

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 …
