Economics Faculty Publications and Presentations

Data from a national survey of 348 U.S. sports field managers were used to examine the effects of participation in Cooperative Extension events on the adoption of turfgrass weed management practices. Of the respondents, 94% had attended at least one event in the previous 3 yr. Of this 94%, 97% reported adopting at least one practice as a result of knowledge gained at an Extension turfgrass event. Half of the respondents had adopted four or more practices; a third adopted five or more practices. Nonchemical, cultural practices were the most-adopted practices (65% of respondents). Multiple regression analysis was used to …

Costs Of Wind Erosion In The Northern Agricultural Region, Anne Bennett

Natural resources published reports

Summary

• To date, the Department of Primary Industries and Regional Development’s (DPIRD) estimated opportunity cost of wind erosion for Western Australia’s (WA) agricultural region has only included the costs of forgone production income and therefore underestimates the broader costs of wind erosion events.
• This underestimation of costs was the impetus to create a case study to give an indication of the magnitude of the costs of wind erosion from agricultural land.
• Farmers in the Northern Agricultural Region (NAR) were contacted to seek information about the on-farm costs of wind erosion events that occurred in 2020. Seventeen farmers responded to the …

An Intersectional Approach To Quantifying The Impact Of Geographic Remoteness And Health Disparities On Quality-Adjusted Life Expectancy: Application To Australia, Peter Lee, Steven J. Bowe, Lidia Engel, Erica I. Lubetkin, Nancy Devlin, Lan Gao

International Labour Migration, Farmland Fallowing, Livelihood Diversification And Technology Adoption In Nepal, Karki Nepal, Mani Nepal, Randall Bluffstone

Economics Faculty Publications and Presentations

This article investigates the effect of temporary international labour migration on farmland fallowing, adoption of agricultural intensification technologies and livelihood diversification. Using nationally representative data, combined with empirical methods that allow causal inference, the authors find that households with international migrants are over 50 per cent more likely (based on propensity score matching estimates) to have fallow land than those without. Temporary international migration promotes the adoption of some agricultural intensification technologies and causes rural households to diversify their livelihoods. Land fallowing may increase food insecurity, while agricultural intensification may improve it, for an uncertain net effect.

Anticipatory Impacts Of The Repeal Of Roe V. Wade On Female College Applicants, Janna Wisniewski, Brigham Walker, Jillian Torres, Rajiv Sharma

Economics Faculty Publications and Presentations

We examined the relative impact of the anticipated repeal of Roe v. Wade on the share of female applicants to universities in states where abortion was banned compared with universities in states where abortion remained legal. Using the Common Data Sets from 71 of the top 100 institutions in the United States spanning 27 states from academic years 2018–2022, we found that there was a nearly one percentage point relative decrease in the share of female undergraduate applicants to institutions in ban states compared with states in which abortion remained legal. This suggests that undergraduate applicants are sensitive to state …

Pandemic Impacts On Women’S Mental Health: A Literature Review, Wenqi Gong

Honors Scholar Theses

For many years, women's mental health has been a topic of discussion in the research field, and these problems are usually regarded as the result of gender inequality. This study identifies mental health differences among women in different family structures in the context of a pandemic, by citing scenario-based research from 2020 to 2023. More specifically, by comparative analysis, disparities in a series of variables are observed between married and unmarried women. These findings figure out risk factors that tend to distress women. The literature review emphasizes the huge challenges confronting women today, and the root causes of the psychological …

Exchange Rate Responses And Volatility Spillover Effects During The Covid-19 Pandemic In Indonesia, Panky Tri Febiyansah

Economics and Finance in Indonesia

This paper aims to assess the impact of the confirmed COVID-19 cases, the timing of the outbreak, and physical measures on the returns and spillover effects of exchange rate in Indonesia. The model will be tested by the exponential generalized autoregressive conditional heteroskedastic (EGARCH) process and the spillover volatility index. The study discovers that the confirmed cases, outbreak news, and the implementation of large-scale social restrictions simultaneously contribute to a leverage effect on the volatility of a direct quote of Indonesian Rupiah to Australian Dollar, Euro, US Dollar, Singapore Dollar, and Great British Pound. To a certain extent, the heatwave …

The Effect Of Financial Inclusion On Food Security: Evidence From Developing And Developed Countries, Yasmin Yasmin, Sekar Utami Setiastuti

Economics and Finance in Indonesia

This study investigates the global impact of financial inclusion on food security, with a focus on both developing and developed countries. The study constructs a financial inclusion index using the Sarma method and secondary data sourced from IMF and World Bank databases. System GMM is employed as the estimation method due to its effectiveness in addressing endogeneity issues and its efficient and consistent use of instruments. The analysis reveals that financial inclusion has a positive and statistically significant effect on food security across all research sub-samples. In addition, the study incorporates interaction variables between financial inclusion and the COVID-19 pandemic …

Dynamic Factor Copula Models With Estimated Cluster Assignments, Dong Hwan Oh, Andrew John Patton

Research Collection School Of Economics

This paper proposes a dynamic multi-factor copula for use in high-dimensional time series applications. A novel feature of our model is that the assignment of individual variables to groups is estimated from the data, rather than being pre-assigned using SIC industry codes, market capitalization ranks, or other ad hoc methods. We adapt the k-means clustering algorithm for use in our application and show that it has excellent finite-sample properties. Applying the new model to returns on 110 US equities, we find around 20 clusters to be optimal. In out-of-sample forecasts, we find that a model with as few as five …

Social Media Impacts On Arkansas Consumer Perceptions Of Gmos, Elizabeth R. Berner

Graduate Theses and Dissertations

This study builds upon previous consumer perceptions of GMOs studies. A need existed to determine what, if any, effects social media messages about GMOs had on consumer perceptions in Arkansas. The study utilized a qualitative approach with three focus groups. Data were analyzed using descriptive code. Participants were found to have a general understanding of GMOs, though discussion about what a GMO product was took an uncertain tone. Most participants did not consider GMOs as a factor when purchasing products. Rather participants considered characteristics such as price, quality, and convenience. Participants did not believe the infographics had changed their opinions …

Three Essays On International Migration And Remittances, Mir Tanzim Nur Angkur

The research objectives and findings of each of the three essays is summarized below:

The first essay, titled “ Do remittances protect against child marriages? The Rohingyas in Bangladesh”, focuses on the role that remittances could play in combating this harmful practice among the displaced Rohingya population. Nearly one million Rohingya refugees have been living in one of the world’s largest refugee camp in Cox’s Bazar, Bangladesh. I …

Becoming A Father, Staying A Father: An Examination Of The Cumulative Fatherhood Wage Premium To U.S. Residential Fathers, Ohjae Gowen

Research Collection School of Social Sciences

The instability of fathers’ co-residence with children has become an increasingly prevalent experience for U.S. families. Despite long-standing scholarship examining the relationship between fatherhood and wage advantages, few studies have investigated how variation in fathers’ stable co-residence with a child may produce temporal changes in the wage premium over the life course. Building on prior explanations of the fatherhood wage premium, I test if the wage premium grows with time since the birth of a resident child and if the premium depends on fathers’ co-residence with a child. I use marginal structural models with repeated outcome measures and data from …

China’S Changing Perspective On The Wto: From Aspiration, Assimilation To Alienation, Henry S. Gao

Research Collection Yong Pung How School Of Law

Since its accession to the WTO twenty years ago, China’s image has shifted from a good student aspiring to assimilate itself into the multilateral trading system to one that is increasingly alienated from key WTO principles. How has China’s perspective on WTO been evolving? What are the reasons behind China’s changing perspective? This chapter addresses these questions from the Chinese perspective with a comprehensive analysis of the key moments in China’s first two decades in the WTO, followed by practical suggestions on how to engage China more constructively in the WTO and beyond.

Essays On The Economics Of Hurricanes, Haishan Yang

All Graduate Theses and Dissertations, Fall 2023 to Present

This dissertation explores how Hurricanes Katrina and Rita affected the economy in New Orleans and nearby areas in Louisiana. Using a variety of econometric techniques, my dissertation aims to understand the effects of these storms on employment, wages, and housing prices.

In the first essay, I focus on employment in New Orleans. I find that Katrina led to significant and lasting job losses in nearly every sector, while the construction sector stood as an exception, recovering within just three months. Interestingly, wages increased in most sectors. This suggests that with fewer workers available, those who remained became more valuable, leading …

An Analysis Of Poverty Convergence: Evidence From Pennsylvania Counties, Angel Alcantara, Stephanie M. Brewer, James J. Jozefowicz

The Journal of Economics and Politics

This paper extends applications of unconditional and conditional β-convergence and σ-convergence analysis to poverty rates in a panel data sample of Pennsylvania counties during the period 1990-2019. Spatial structural breaks between rural and urban counties in Pennsylvania plus the possibility that Philadelphia County is an outlier are acknowledged to avoid spurious inferences. The findings support the existence of unconditional β-convergence in the pooled, urban, and rural samples with non-metropolitan areas exhibiting the greatest convergence. However, the largest conditional β-convergence is observed for urban counties, and this outcome is robust to the exclusion of Philadelphia County. Graphical evidence evinces a greater …

Behavioral Science Interventions Could Increase Snap Comprehension And Awareness Among Military Families, Colleen Heflin, Hannah Patnaik, Leonard M. Lopoo, Siobhan O'Keefe

Population Health Research Brief Series

Food insecurity is more common among military families than the general population, and the transition from active service to civilian life is a time of heightened risk. The Supplemental Nutritional Assistance Program (SNAP) is designed to support food security among low-income families. Many eligible military and veteran families do not enroll in SNAP due to a lack of information, stigma, and administrative barriers. This brief highlights findings from a survey experiment conducted in 2022 and 2023 to assess how small changes to SNAP informational flyers, such as simplifying information provided about SNAP, highlighting that other veterans use SNAP, and emphasizing …

Analyzing Household Income Inequality: A Subgroup Decomposition Of Generalized Entropy Measures, Jazib Mumtaz, Sayed Irshad Hussain

CBER Conference

The study proves that education level, nature of employment, asset ownership, and gender contribute significantly to income inequality. The study further indicates that changes in income distribution for the bottom of the population through paid employment, female income, and asset ownership could impact income inequality. The study's results can be used to assess policy impact on social welfare and help policymakers design targeted interventions, develop efficient taxation, and create a sustainable model for inclusive growth.

Local Competition, Multimarket Contact, And Product Quality: Evidence From Internet Service Provision, Kyle Wilson

Pomona Faculty Publications and Research

I investigate the effect of competition on quality in the internet service provision industry: I examine both local competition within markets and multimarket contact among firms across markets. This industry offers an ideal setting, as quality is both objective and measurable. I use data from speedtest.net from 2008 to 2014 to estimate a reduced-form model of the effects of local competition and multimarket contact on realized consumer download speeds. I find that increased multimarket contact leads to decreased download speeds, which is consistent with the mutual forbearance hypothesis. I also find that duopolies lead to faster download speeds than do …

Relationship Between Human Capital And Urban Growth, Lucky Bizenjo

CBER Conference

This study has provided new insights into the relationship between urbanization and human capital, made its implications at the global income group level and national level. In the first study, panel data of 87 countries used from 1991 to 2019. The results showed that education is found to be negatively and insignificantly associated with urbanization at the global level, but it is found to be positive (though insignificant) in low-income countries, and positive and significant in low-income countries and middle-income countries, and high-income countries. Our research suggests that as the income of a country increases, the contribution of education to …

Background

In industrialized populations, low male testosterone is associated with higher rates of cardiovascular mortality. However, coronary risk factors like obesity impact both testosterone and cardiovascular outcomes. Here, we assess the role of endogenous testosterone on coronary artery calcium in an active subsistence population with relatively low testosterone levels, low cardiovascular risk and low coronary artery calcium scores.

Methodology

In this cross-sectional community-based study, 719 Tsimane forager-horticulturalists in the Bolivian Amazon aged 40+ years underwent computed tomography (49.8% male, mean age 57.6 years).

Results

Coronary artery calcium levels were low; 84.5% had no coronary artery calcium. Zero-inflated negative binomial models …

Minimum Wages And Racial Discrimination In Hiring: Evidence From A Field Experiment, Alec Brandon, Justin E. Holz, Andrew Simon, Haruka Uchida

Upjohn Institute Working Papers

When minimum wages increase, employers may respond to the regulatory burdens by substituting away from disadvantaged workers. We test this hypothesis using a correspondence study with 35,000 applications around ex-ante uncertain minimum wage increases in three U.S. states. Before the increases, applicants with distinctively Black names were 19 percent less likely to receive a callback than equivalent applicants with distinctively white names. Announcements of minimum wage hikes substantially reduce callbacks for all applicants but shrink the racial callback gap by 80 percent. Racial inequality decreases because firms disproportionately reduce callbacks to lower-quality white applicants who benefited from discrimination under lower …
