External Financing, Governance, And Infrastructure Development: Evidence From Sub-Saharan Africa, Afees Oluwashina Noah, Oladipo Olalekan David

CSID Journal of Infrastructure Development

Infrastructure development in Sub-Saharan Africa (SSA) requires diversified financing strategies to address a significant funding shortfall that cannot be met by domestic resources alone. This research evaluates the contributions of external financing—namely Official Development Assistance (ODA), Foreign Direct Investment (FDI), and Private Participation in Infrastructure (PPI)—in complementing domestic efforts to advance infrastructure in SSA. It examines their influence, alongside governance, on the development of physical and social infrastructure components. Employing methodologies such as Panel-Corrected Standard Errors (PCSE) and System Generalized Method of Moments (SGMM) across 43 SSA economies from 2000 to 2022, the analysis reveals that FDI substantially enhances physical …

Forecasting Crime Rates Utilizing Machine Learning And Economic Indicators, Owen Miller

Honors Projects

Abstract: The following project utilized the correlation between economic indicators and crime rates to build tree-based machine learning algorithms that predict monthly crime rates in Ohio. The goal of the study was to answer how economic variables could be used in forecasting county level crime rates. A sample of 9 counties were utilized in building regression trees, random forests and evolutionary random forest models. The study concluded that lagged crime rates provided the best predictive ability in forecasting models, while economic variables provided more accuracy to property crime. The study could be furthered by creating models at the department level …

The Impact Of Technological Change On Achieving Sustainable Development: Panel Data Analysis On Emerging Countries (2004-2024), Mayar Walid Al, Ahmed Tarek Ta

Future Journal of Social Science

It seeks to understand how advancements in information and communication technologies, renewable energy, and manufacturing processes shape economic, social, and environmental sustainability (Geels et al., 2017; UNEP, 2021). Using panel data analysis, the research quantifies the relationship between technological indicators, such as ICT penetration and renewable energy adoption, and sustainable development outcomes, including GDP growth, environmental health, and social inclusion (Sadorsky, 2010; Shahbaz et al., 2016).

The findings reveal …

Striking A Balance: Market Shock & Responses In Automotive Components Manufacturing, Emma Lane Mcgahey

All Theses

This thesis examines the effects of extreme market shocks on supply chain dynamics within the automotive industry. Through an analysis of demand data from an automotive manufacturer to its component suppliers (January 2018 to May 2024), the study investigates the relationship between market shocks and supply chain responses, providing insights into how auto components inventory management handles downstream responses to market shocks. With supporting public data—from FRED, BLS, and the U.S. Census Bureau resources—we explore two primary relationships: the impact of market shocks on the Average Standard Deviation of Demand (SDO) and the effect of demand variability on expedited pricing …

Financial Risk In A Changing Climate, Mashuk S. Rahman

LSU New Orleans Theses and Dissertations

Essay 1:

Given the missing-not-at-random (MNAR) nature of carbon emissions figures under the voluntary disclosure regulator environment, this research imputes synthetic emissions figures for both disclosing and non-disclosing publicly traded US firms, using an IV approach adapted for sample bias correction. The forward-observing implied cost of equity capital measure is consistently higher for carbon-intensive firms regardless of disclosure decision. This higher cost found in the large swath of high-emitting firms reduces the net present value of green transition investments, thus fueling existing research on the counterproductive natures of capital allocation in efforts to reduce corporate pollution. Contrary to emerging research, …

Estimating The Impacts Of Utah's Down Payment Assistance Program (Sb240): A Framework For Analyzing State And Regional Dpa Policies, Dylan Fallentine

All Graduate Reports and Creative Projects, Fall 2023 to Present

I examine the impact of Utah's Senate Bill 240, a targeted down payment assistance program for new homes priced under $450,000, on housing affordability and developer behavior. Using Synthetic Difference-in-Differences, Bayesian Structural Time-Series, Fixed Effects Difference-in-Differences, and Event Study Analysis, I assess whether SB240 influenced the construction of more affordable homes and led to reduced lot sizes, thereby fueling affordability.

My empirical analysis reveals that SB240 significantly reduced the transaction price of entry-level new homes in Utah, with an estimated average reduction of approximately $23,000. This effect is robust across various econometric models and data pools, indicating that the policy …

Estimating The Effect Of Residential Sales Prices On Building Permits, Emilio Becerra

All Theses

This paper addresses home sales prices’ impact on residential building permit authorization in South Carolina’s Greenville and Richland counties amid the COVID-19 pandemic. The estimation uses a comprehensive data set of the housing markets in both counties for 2016 to 2022, incorporating 88,098 home sales. The analysis exploits the variation in sales prices of homes to analyze the sensitivity in the supply of permits to builders through an instrumental variables approach. Using two instruments, violent crimes and household income, the effect of sales prices on the supply of building permits is positive and statistically significant. Included in the first-stage regression …

How To Discipline Financial Markets: Reputation Is Not Enough, Maria Bigoni, Gabriele Camera, Marco Casari

ESI Working Papers

Historically, shocks originating in the financial sector often spilled over into the real sector with dramatic consequences. We study in the lab how interventions targeting disclosure and capital requirements of financial intermediaries can reduce insolvencies or prevent their negative effects from propagating to the broader economy. In our two-sector economy, consumers and producers can fund financial intermediaries, who, in turn, provide them with liquidity to settle trades. However, intermediaries may undertake risky investments and become insolvent, which depresses real economic activity. In the experiment, insolvencies were frequent. As a consequence, consumers and producers often refused to fund intermediaries, which lowered …

Optimal Har Inference, Liyu Dou

Research Collection School Of Economics

This paper addresses the problem of deriving heteroskedasticity and autocorrelation robust (HAR) inference for a scalar parameter of interest, under the assumption of a known upper bound on data persistence. Finite-sample optimal tests are derived within the Gaussian location model, revealing that robustness-efficiency tradeoffs are primarily determined by the maximal persistence. With a suitable adjustment to the critical value, the equal-weighted cosine (EWC) test emerges as nearly optimal, wherein the long-run variance is estimated through projections onto q type II cosines. This approach establishes a direct link between the choice of q and persistence assumptions, accompanied by adjustments to the …

Pengaruh Larangan Ekspor Karang Hias Terhadap Kondisi Terumbu Karang Di Indonesia, Fitrian Dwi Cahyo, Muhammad Halley Yudhistira

Jurnal Kebijakan Ekonomi

Indonesia has the largest coral population in the world, contributed as the world’s second largest ornamental corals exporter after Japan. Coral trade sparked the issues of habitat destruction, illegal trade, and coral health problems has prompted the government to banning of ornamental coral export. This study aims to find an empirical evidence does the policies mentioned above affect the condition of coral reefs in Indonesia. The author uses the Fixed-Effect Model on the Difference in Difference regression equation whose result show that export banning of ornamental corals does not significantly affect the condition of coral reefs in Indonesia.

Granulocyte Colony Stimulating Factor Promotes Scarless Tissue Regeneration, Jianhe Huang, Satish: Murphy Sati, Casey A. Spencer, Emmanuel Rapp, Stephen M. Prouty, Scott Korte, Olivia Ahart, Emily Sheng, Anna E. Kersh, Denis Leung, Thomas H. Leung, Leung, Denis H. Y.

Mammals typically heal with fibrotic scars, and treatments to regenerate human skin and hair without a scar remain elusive. We discovered that mice lacking C-X-C motif chemokine receptor 2 (CXCR2 knockout [KO]) displayed robust and complete tissue regeneration across three different injury models: skin, hair follicle, and cartilage. Remarkably, wild-type mice receiving plasma from CXCR2 KO mice through parabiosis or injections healed wounds scarlessly. A comparison of circulating proteins using multiplex ELISA revealed a 24-fold higher plasma level of granulocyte colony stimulating factor (G-CSF) in CXCR2 KO blood. Local injections of G-CSF into wild-type (WT) mouse wound beds reduced scar …

Estimating Firm-Level Production Functions With Spatial Dependence, Pao-Li Chang, Ryo Makioka, Bo Lin Ng, Zhenlin Yang

Research Collection School Of Economics

This paper proposes a three-stage efficient GMM estimation algorithm for estimating firm-level production functions given spatial dependence across firms due to supplier-customer relationships, sharing of input markets, or knowledge spillover. The procedure builds on Ackerberg, Caves and Frazer (2015) and Wooldridge (2009), but in addition, allows the productivity process to depend on the lagged output levels and lagged input usages of related firms, and spatially correlated productivity shocks across firms, where the set of related firms can differ across the three dimensions of spatial dependence. We establish the asymptotic properties of the proposed estimator, and conduct Monte Carlo simulations to …

A Granular Investigation On The Stability Of Money Demand, Zhengyang Chen, Victor J. Valcarcel

Faculty Publications

A large literature has shown money demand functions constructed from simple-sum aggregates are unstable. We revisit the controversy surrounding the instability of money demand by examining cointegrating income-money relationships with the Divisia monetary aggregates for the U.S., and compare them with their simple-sum counterparts. We innovate by conducting a more granular analysis of various monetary assets and their associated user costs. We find characterizing money demand with simple-sum measures only works well in a period preceding 1980. Divisia aggregates, their components, and their user costs provide a more reliable interpretation of money demand. Subsample analysis across 1980 and 2008 suggests …

Assessing The Recreational Charter Fishing Market In Florida: A Hedonic Price Analysis, Mehrnoosh Asadi, Pallab Mozumder, Mahadev G. Bhat

Journal of Ocean and Coastal Economics

In this study we analyze the effect of a wide range of factors on the variation of recreational fishing trip prices in Florida. We collected extensive data from recreational fishing websites maintained by guides and outfitters and used different empirical methods for quantifying the relationship between trip price and various trip characteristics. The Hedonic Price model was used to estimate the implicit prices of freshwater and saltwater fishing trip characteristics. The results suggest that freshwater and saltwater anglers significantly value the lodging feature included in the fishing trip package. Moreover, saltwater anglers had a higher willingness to pay to catch …

Axiomatic Characterization Of Generalized Neo-Eu Preferences And The Falsifiability Of Ambiguity Theories, Manuel Nunez, Mark Schneider

ESI Working Papers

We introduce a new weakening of the independence axiom, co-extreme independence, which we show characterizes a class that encompasses popular ambiguity models including Hurwicz preferences, ϵ-contamination preferences, and NEOEU preferences. Importantly, our representation unifies these as forms of simple ambiguity models as we show that the Vapnik-Chervonenkis (VC) dimension of these models is either unity or increases linearly with the number of states. In contrast, standard ambiguity models characterized in the Anscombe-Aumann framework are complex ambiguity models that have a VC dimension that is either infinite or increases exponentially in the number of states. We show that simple ambiguity preferences …

A Critical Evaluation Of Loss Aversion As The Determinate Of Effort In Compensation Framing, Timothy W. Shields, James Wilhelm

ESI Working Papers

A robust finding in managerial accounting research is that participants prefer contracts framed as bonuses to economically equivalent contracts framed as penalties. Another finding is that participants put forth more effort when facing penalty contracts than equivalent bonus contracts. Both results are commonly described as due to loss aversion, an integral portion of prospect theory. We test whether loss aversion is correlated with higher effort in an experiment with two parts. In the first part, we elicit individual participants' loss aversion using two measures. In the second part of the experiment, participants choose costly effort to increase the likelihood of …

On Explaining Why The (Human) World Is Rich, Bart J. Wilson

ESI Working Papers

The wealth of the modern world is a natural historical marvel. Explaining it has traditionally been the purview of economic historians, as exemplified by the recent book How the World Became Rich by Mark Koyama and Jared Rubin. Economic historians, though, tend to only ask process-oriented “how” questions and “by what means” questions of the Great Enrichment. The eight co-authors of Explaining Technology, who are not economic historians, engage the debate asking a different question. Their goal is to explain the exponential shape of our enrichment with a model of the combinatorial evolution of technology. With an eye toward how …

Quantifying Delay Propagation In Airline Networks, Liyu Dou, Jakub Kastl, John Lazarev

Research Collection School Of Economics

We develop a framework for quantifying delay propagation in airline networks by integrating structural modeling and machine learning methods to estimate causal effects. Using a comprehensive dataset on actual delays and a model-selection algorithm (elastic net), we estimate a weighted directed graph of delay propagation for each major airline in the United States and establish conditions under which the propagation coefficients are causal. These estimates enable a decomposition of airline performance into "luck" and "ability." Our findings indicate that luck accounts for approximately 38% of the performance difference between Delta and American Airlines in our data. Additionally, we leverage these …

Recruitment Of Cxcr4+Type 1 Innate Lymphoid Cells Distinguishes Sarcoidosis From Other Skin Granulomatous Diseases, S. Sati, J. Huang, A.E. Kersh, P. Jones, O. Ahart, C. Murphy, S.M. Prouty, M.L. Hedberg, V. Jain, S.G. Gregory, Leung, Denis H. Y., J.T. Seykora, M. Rosenbach, T.H. Leung

Research Collection School Of Economics

Sarcoidosis is a multiorgan granulomatous disease that lacks diagnostic biomarkers and targeted treatments. Using blood and skin from patients with sarcoid and non-sarcoid skin granulomas, we discovered that skin granulomas from different diseases exhibit unique immune cell recruitment and molecular signatures. Sarcoid skin granulomas were specifically enriched for type 1 innate lymphoid cells (ILC1s) and B cells and exhibited molecular programs associated with formation of mature tertiary lymphoid structures (TLSs), including increased CXCL12/CXCR4 signaling. Lung sarcoidosis granulomas also displayed similar immune cell recruitment. Thus, granuloma formation was not a generic molecular response. In addition to tissue-specific effects, patients with sarcoidosis …

Do Participation Rates Vary With Participation Payments In Laboratory Experiments?, Huizhen Zhong, Cary Deck, Daniel J. Henderson

ESI Working Papers

This paper reports a series of experiments designed to evaluate how the advertised participation payment impacts participation rates in laboratory experiments. Our initial goal was to generate variation in the participation rate as a means to control for selection bias when evaluating treatment effects in common laboratory experiments. Initially, we varied the advertised participation payment to 1734 people from $5 to $15 using standard email recruitment procedures, but found no statistical evidence this impacted the participation rate. A second study increased the advertised payment up to $100. Here, we find marginally significant statistical evidence that the advertised participation payment affects …

The Influence Of Socio-Economic Constraints On Women's Economic Empowerment In Kenya: Evidence Of Wage Disparities?, Wairimu Kimani

McNair Summer Research Program

This study presents an econometric analysis of socio-economic factors which influence wage inequalities in Kenya. This study tests the hypothesis that women experience cross sectoral gender wage disparities which are influenced by cultural and social expectations. Linear, logistic, factorial regressions models and the Mann-Whitney test were utilized to identify statistical determinants of the gender-wage gap through disproportionate educational outcomes, labor outcomes, and social outcomes. The outcomes reflect that education and other demographic factors play a pivotal role in the wage and employment outcomes for women in Kenya. The results suggest that cultural implications are the main influence to the socio-economic …

When Hedge Funds Move In: Socioeconomic Consequences Of Single-Family Rentals, Hannah Misurati

All Theses

In this thesis I explore the effect of increased investment in the single-family rental sector on inequality and housing affordability. I measure the effect of the single family rental (SFR) share on Gini indices and median rental prices across the largest U.S. cities. I construct three non lagged and three lagged models for each of the two dependent variables. In my analysis of the relationship between SFR shares and inequality, I do not find a significant relationship after accounting for potential reverse causality. However, the relationship between SFR shares and rent prices is shown to be negative and significant once …

Estimating The Effect Of Nuclear Energy On A Country's Electricity Generation Mix: Fukushima As A Case Study, Sarah Elizabeth Zarrilli

All Theses

In this paper, I attempt to estimate the true effects of removing nuclear energy on a country’s energy portfolio, particularly how the country substitutes to other fuel sources for electricity generation and how it impacts the country’s marginal electricity prices. In 2011, anti-nuclear sentiment that arose in Japan following the meltdown of the Fukushima prefecture’s nuclear power plant resulted in the country decreasing its nuclear electricity generation from over 30% of its total supply to 0% in under two years. I use the dramatic variation across Japan’s electricity supply regions over the denuclearization period to attempt to estimate the true …

How Are Global Trade Relationships Affected By Western Sanctions?, Colin A. Martinez

All Graduate Reports and Creative Projects, Fall 2023 to Present

Do sanctions actually have an impact on their intended targets? This paper seeks to fill a gap in the existing literature on the effectiveness of sanctions by measuring potential impacts on the trade relationships of targeted states after the imposition of sanctions. To do so, it turns to a comprehensive dataset that combines all trade and sanctions data for each of 229 states, arranged in 23,132 dyads, from 2000 through 2019. It then examines 792 regressions using a hybrid fixed effects difference-in-difference model applied to twelve different types of sanctions, differentiated by the sanctioning state’s membership in certain groups of …

Measurement Reliability For Intentions To Change Behavior, Emily Schlichtig

Graduate Theses and Dissertations

It is common for researchers to ask participants to associate probabilities with words, often using tools like the Likert scale to measure behavioral intentions and attitudes. However, it remains unclear what specific probabilities participants assign to the response options on a Likert scale, how much variation exists across these options, and whether these probabilities differ across various behaviors. The purpose of this paper is to explore the numeric probabilities that participants associate with different Likert scale points, to understand their perception of the variation at each point, and to compare these perceptions across three behaviors: eating more vegetables, exercising more, …

Gradient Wild Bootstrap For Instrumental Variable Quantile Regressions With Weak And Few Clusters, Wenjie Wang, Yichong Zhang

Research Collection School Of Economics

We study the gradient wild bootstrap-based inference for instrumental variable quantile regressions in the framework of a small number of large clusters in which the number of clusters is viewed as fixed, and the number of observations for each cluster diverges to infinity. For the Wald inference, we show that our wild bootstrap Wald test, with or without studentization using the cluster-robust covariance estimator (CRVE), controls size asymptotically up to a small error as long as the parameter of endogenous variable is strongly identified in at least one of the clusters. We further show that the wild bootstrap Wald test …

Exploring The Motivations And Determinants Of Farmer’S Market Consumers And Organic Specialty Crop Producers, Jane Arnold

All Theses

This two-chapter thesis evaluates the motivations and determinants of the central figures in farmers’ markets and organic markets. The first chapter explores the rise of farmers’ markets popularity through an in-person survey that was designed and distributed to 274 farmers' market consumers. Logit and ordered logit regressions were used to identify the motivations and characteristics that affect the likelihood of being a frequent farmers’ market customer (visiting 5 times or more per season) and spending over $50. The second chapter investigates the organic markets for cucumber and kale, which are dominant specialty crops on today’s grocery shelves. To identify the …
