Digital Twinning For Resilient Global Supply Chains: Three Case Studies, Gawon Yun, Douglas N. Hales, Leo Hong

Markets, Globalization & Development Review

Global supply chains have vulnerabilities, and these escalate in crisis times like pandemics or wars. Digital twinning of supply chains can provide early alerts and timely interventions. We examined three companies in different industries using Digital Twin (DT) technology to improve their supply chain performance. We found that while DT successfully enhanced performance indicators, the dollar and time costs were significant, creating barriers to wider DT adoption. We conclude by outlining the positives and negatives of implementing Digital Twins in global supply chains.

Climate Change Adaptation Through Economic Democracy, Shriraksha Mohan

Student Papers in Local and Global Regional Economies

As global climate change poses a serious threat to humanity's survival, equitable and just climate change adaptation has become the focus of several climate movements, social justice groups, governments, and international organizations. Climate sciences and studies have concluded that climate change not only impacts the planet's natural ecosystems, but also has cascading negative consequences on society and the economy. The existing paradigm of economic development has created vast wealth and resource inequality. The inequality further exacerbates the ill effects of climate change and makes vulnerable communities bear a disproportionate amount of the burden of climate catastrophes. This necessitates replacing the …

Clark Fork River Pedal & Farm Tour, Plains, Montana, Kika Bradford, Megan Schultz, Rebekah Ficek

Institute for Tourism and Recreation Research Publications

This study was conducted to provide insight into the characteristics of attendees of the 2024 Clark Fork River Pedal & Farm Tour. 43 participants completed online surveys. The 2024 Clark Fork River Pedal & Farm Tour in Plains, Montana, attracted a diverse group of visitors, with 60.5% from Montana and 39.5% from out of state. The event was the primary reason for 91.7% of attendees’ visits, and 72.7% of non-local participants stayed at least one night, averaging 2.84 nights. This led to significant spending, particularly on accommodations and dining, totaling $6,524.00. Overall satisfaction was high, with 85.7% indicating they would …

What Is The Fallacy Of Approximation?, Matthew Hammerton, Sovan Patra

Research Collection School of Social Sciences

Many philosophers appeal to the “fallacy of approximation”, or “problem of second best”. However, despite the pervasiveness of such appeals, there has been only a single attempt to provide a systematic account of what the fallacy is. We identify the shortcomings of this account and propose a better one in its place. Our account not only captures all the contexts in which approximation-based reasoning occurs but also systematically explains the several different ways in which it can be in error.

Gmm Estimation With Brownian Kernels Applied To Income Inequality Measurement, Jin Seo Cho, Peter C.B. Phillips

Cowles Foundation Discussion Papers

In GMM estimation, it is well known that if the moment dimension grows with the sample size, the asymptotics of GMM differ from the standard finite dimensional case. The present work examines the asymptotic properties of infinite dimensional GMM estimation when the weight matrix is formed by inverting Brownian motion or Brownian bridge covariance kernels. These kernels arise in econometric work such as minimum Cramer-von Mises distance estimation when testing distributional specification. The properties of GMM estimation are studied under different environments where the moment conditions converge to a smooth Gaussian or non-differentiable Gaussian process. Conditions are also developed for …

Human Capital As A Driving Force For Economic Growth In Gcc Countries: Pooled Mean Group Estimation, Mohamed Sharif Bashir Elsharif

Muthanna Journal of Administrative and Economics Sciences

This study explored the relationship between human capital metrics and economic growth in the Gulf Cooperation Council (GCC) countries from 2000 to 2022. This research utilized a pooled mean group-autoregressive distributed lag approach to empirically assess the influence of selected macroeconomic factors—specifically human capital, gross capital formation, government expenditure on health and education, and foreign direct investment (FDI)—on gross domestic product. The results indicated that, in the short term, all human capital indicators positively impacted economic growth, except for FDI. Conversely, in the long term, all variables’ impact was positive and significant. School enrollment, governmental spending on education and health, …

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 …

Strategies For Implementing Organizational Change In The Construction Industry, Ivette Dejesus

Walden Dissertations and Doctoral Studies

Construction business leaders are concerned with failed change initiatives as they have the potential to affect profitability. Grounded in five-P theory, the purpose of this qualitative multiple case study was to explore the strategies that some leaders in construction companies use to implement change initiatives successfully. The participants consisted of five business leaders from three construction companies who have successfully implemented change initiatives within their organization. Data were collected using semi-structured interviews and a collection of organizational documents. Through thematic analysis, five themes emerged: (a) goal setting and planning, (b) effective communication, (c) stakeholder involvement, (d) effective resource and cost …

Nevada’S Predictable Housing Train Wreck And What To Do About It, Arthur C. Nelson

Policy Briefs and Reports

Nevada is on the cusp of a housing catastrophe, especially in Southern Nevada.

Consider that the state has fewer households than it should. A household is defined as one or more people who have a home of their own. But for price, location, configuration, and other factors, about 60,000 households in Nevada do not exist because there is no home for them. And it’s going to get worse. Including these “missing households,” nearly 470,000 new occupied homes will need to be built between 2020 and 2040 to meet the housing needs of all Nevadans, or about 23,000 per year. The …

Herding With Heterogeneous Ability: An Application To Organ Transplantation, Stephanie De Mel, Kaivan Munshi, Soenje Reiche, Hamid Sabourian

Cowles Foundation Discussion Papers

There are many economic environments in which an object is offered sequentially to prospective buyers. It is often observed that once the object for sale is turned down by one or more agents, those that follow do the same. One explanation for this phenomenon is that agents making choices further down the line rationally ignore their own assessment of the object and herd behind their predecessors. Our research extends the canonical herding model by allowing agents to differ in their ability to assess the quality of the offered object. We develop novel tests of herding based on this ability heterogeneity …

Inference In A Stationary/Nonstationary Autoregressive Time-Varying-Parameter Model, Donald W.K. Andrews, Ming Li

Cowles Foundation Discussion Papers

This paper considers nonparametric estimation and inference in first-order autoregressive (AR(1)) models with deterministically time-varying parameters. A key feature of the proposed approach is to allow for time-varying stationarity in some time periods, time-varying nonstationarity (i.e., unit root or local-to-unit root behavior) in other periods, and smooth transitions between the two. The estimation of the AR parameter at any time point is based on a local least squares regression method, where the relevant initial condition is endogenous. We obtain limit distributions for the AR parameter estimator and t-statistic at a given point τ in time when the parameter exhibits unit …

Efficiency Costs Of Unemployment Insurance Denial: Evidence From Randomly Assigned Examiners, Jonathan Cohen, Geoffrey C. Schnorr

Upjohn Institute Working Papers

Approximately 10 percent of Unemployment Insurance (UI) claimants in the United States are denied benefits after being deemed at-fault for their job loss by a government examiner. Using administrative data from California and an examiner leniency design, we estimate the causal effects of extending eligibility to marginally at-fault claimants—those whose job separation reason would be deemed UI-eligible by some examiners but UI-ineligible by others. Approving a marginally at-fault claimant increases UI benefits paid by over $3,000 and lengthens the nonemployment spell by just under two weeks, but it does not decrease labor income. We combine these estimates and other relevant …

Re-Evaluating The Preferences Of Recreational Gulf Of Maine Cod And Haddock Anglers, Andrew M. Carr-Harris, Scott Steinback

Journal of Ocean and Coastal Economics

Since 2013, fisheries managers have used a bioeconomic model to simulate the effect of proposed regulations on angler participation and subsequent fishing mortality for Gulf of Maine Atlantic cod and haddock using data from a choice experiment survey. In the year following the last choice experiment survey, however, Gulf of Maine cod fishery experienced unprecedented regulatory changes that, to this day, considerably limit recreational harvest. Given the potential influence of these regulatory changes on angler targeting behavior and preferences, we administered a new choice experiment survey in 2019. The new survey instrument and the sampling method were updated relative to …

Teachers' Financial Literacy Knowledge And Self-Efficacy: A Phenomenological Study, Alyssa Lynne Eisenhart

Doctoral Dissertations and Projects

The purpose of this hermeneutic phenomenological study was to discover the experiences and self-efficacy beliefs related to financial literacy knowledge for educators in the United States. The theory guiding the study was self-efficacy as it explained how one’s belief in abilities is shaped by their unique background, experiences, and knowledge. The central research question was what are the experiences and self-efficacy beliefs of educators who teach financial literacy? The study aimed to understand the perspectives of teachers as it related to financial knowledge and self-efficacy. A purposive sample, with ten to fifteen participants, were selected based on the criteria that …

Industry 4.0 And The Solution To The Austrian Knowledge And Calculation Problem: A Grounded Case Analysis, Robbie Davis

Doctoral Dissertations and Projects

The dissertation consists of five chapters examining the current state of the Austrian knowledge and calculation problems which have long been characterized as indestructible barriers to a functional, state-controlled central planning body. Modern technological advancements in computing and communications have introduced to the market the means with which to have near perfect knowledge of all information at every stage in the supply and demand processes. Related literature does little more than theorize on industry 4.0’s impact while this research seeks to discover the extent to which industry 4.0 has overcome the Austrian knowledge and calculation problem by analyzing specific ground-level …

Cyclical Time Series: An Empirical Analysis Of Temperatures In Central England Over Three Centuries, Liudas Giraitis, Fulvia Marotta, Peter C.B. Phillips

Cowles Foundation Discussion Papers

This paper builds on methodology that corrects for irregular spacing between realizations of unevenly spaced time series and provides appropriately corrected estimates of autoregressive model parameters. Using these methods for dealing with missing data, we develop time series tools for forecasting and estimation of autoregressions with cyclically varying parameters in which periodicity is assumed. To illustrate the robustness and flexibility of the methodology, an application is conducted to model daily temperature data. The approach helps to uncover cyclical (daily as well as annual) patterns in the data without imposing restrictive assumptions. Using the Central England Temperature (CET) time series (1772 …

Economic Development, Undernutrition And Diabetes, Kaivan Munshi, Swapnil Singh, Nancy Luke, Anu Mary Oommen

Cowles Foundation Discussion Papers

This research connects two seemingly unrelated facts that have recently been documented in developing countries, with important consequences for global health: (i) the weak association between nutritional status and income, and (ii) the elevated risk of diabetes among normalweight individuals. The model that we develop to reconcile these facts is based on a set point for body size that is adapted to (low) pre-modern food supply, but subsequently fails to adjust to rapid economic change. During the process of development, some individuals thus remain at their low-BMI set point, despite the increase in their income (food consumption), while others who …

Essays On Personal Bankruptcy, Wealth, And Entrepreneurship, Wonjin Lee

Arts & Sciences Graduate Student Theses and Dissertations

The first two chapters of my dissertation study the role of personal bankruptcy in U.S. entrepreneurship. Entrepreneurship inherently carries risk. The majority of businesses are unincorporated, meaning the business debts become personal liabilities for the owner. Consequently, when such a business falters, the owner may be incentivized to file for personal bankruptcy. This paper studies the impact of wealth protection on entrepreneurial activities. Utilizing a regression kink design, I establish a first causal link between potential debt forgiveness and entrepreneurial activities. My findings indicate that more lenient debt relief policies motivate business owners to finance their enterprises. Specifically, an additional …

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 …

Adam Smith, Human Betterment, And His Erroneous Indentification With Self-Interested Human Action, Vernon L. Smith

ESI Publications

In this essay I discuss the proposition that Adam Smith has been widely misinterpreted as asserting in his second book, The Wealth of Nations, that emergent modern economies are driven by the strictly selfish motives of their human inhabitants. The propositions articulated in his first book, The Theory of Moral Sentiments, which offered a theory of society, extended seamlessly into his second book, and continued to be part of his theory of economy. In both works, he distinguished the universal state of being self-interested from actions taken in one's self-interest, and modeled people as creating and following rules of propriety …

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 …

Expanding Healthcare Access For The Undocumented Immigrant Community: The Heal For Immigrant Families Act Of 2023, Perla Torres Estrada

The Gettysburg Journal for Public Policy

When it comes to the topic of universal healthcare, most of us will readily agree that healthcare is a human right. Where this agreement usually ends, however, is on the question of who should be granted this right, and if it should be left to the free market to determine access and affordability. Specifically, the political debate on expanding healthcare access to undocumented immigrants in the United States revolve around concerns over costs, legality, and equity. Proponents maintain that it is a human right whereas opponents question the potential burden on taxpayers and the implication for immigration policy. The HEAL …

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 …

Agrivoltaic Decision Tools For Perennial And Field Crop Farmers, Jill Fitzsimmons, Tae-Hyun Kim

Journal of Extension

This article describes a series of spreadsheet-based tools to help farmers estimate costs, revenues, and yields from agricultural production under different configurations of agrivoltaic installations for field and perennial crops. Crop-specific log books allow farmers to project changes in activity-level costs from the field due to agrivoltaic installations. The whole-farm tool helps farmers aggregate activity-level net returns up to the farm level to calculate projections of trade-offs between crop production with or without agrivoltaic installations. We present tools for lettuce and cranberries, but the tools are comprehensive and inclusive and so can be modified for other perennial and field crops.

Exploring The Experiences Of African American Women Parents’ Role Regarding Financial Socialization In Sacramento, California., Anita Renee Johnson

Walden Dissertations and Doctoral Studies

Financial socialization encompasses the process of acquiring financial values, attitudes, norms, knowledge, and behaviors, with parental influence being pivotal in shaping children's financial understanding and well-being. This study addresses the lack of comprehensive research on the financial socialization experiences of African American women and the role played by parents in shaping their financial management skills, self-efficacy, and identity. By bridging this gap, this study provides valuable insights into the financial socialization processes within African American families, which can have long-term impacts on economic outcomes and wealth-building strategies. Recognizing a gap in the literature, this study addresses the lack of comprehensive …

The Response Of Macroeconomic Variables To Government Spending Shocks In The Sudanese Economy 1989-2019: Comparing The Structural Shocks (Dsge Approach) And Impulse Response (Svar Model), Hassan Tawakol A. Fadol

The Journal of Social Encounters

The importance that different (approaches and models) to modeling the macroeconomy place on theoretical coherence compared to their capacity to match the data and the quality of the econometric model description varies. Dynamic stochastic general equilibrium (DSGE) models are more theoretical, whereas vector autoregression (SVAR) models provide a better match to the data. For developed economies, there are well-established publications on measuring the response of economic indicators to government spending shocks and aggregate macroeconomic activity. In addition, such empirical studies in emerging nations are scarce. This research seeks to fill this void by utilizing the DSGE model and the SVAR …

Factors Influencing Household Adoption Of Rooftop Solar Power In The Philippines: An Empirical Analysis Using The Contingent Valuation Method, Rosalina Palanca-Tan

Economics Department Faculty Publications

The Philippines possesses significant solar energy potential, yet the adoption of rooftop solar power (RTSP) among households remains limited despite its benefits in reducing electricity costs and contributing to the clean energy transition. This study investigates the determinants influencing households’ willingness to adopt RTSP in Metro Manila and surrounding provinces, utilizing the contingent valuation method. Survey results indicate that economic factors, particularly the potential for electricity bill reduction, along with environmental considerations, are positively associated with adoption intentions. While a substantial portion of households (82%) expressed some level of intention to adopt RTSP, the figure drops to 20% when focusing …
