Housing Affordability Impacting Factors In U.S. Urban Areas From 2010 To 2020: An Empirical Review Of Theoretical Factors, Colby Lee Woodson

Community and Regional Planning Program: Theses

This study examines housing affordability in United States Combined Statistical Areas (CSAs) and counties from 2010 to 2020, using American Community Survey and Building Permits Survey data. It evaluates theoretical frameworks from George Galster and Kwan Ok Lee. Using a multiscalar approach, affordability is assessed through a costs-over-income ratio, incorporating both supply- and demand-side factors. A novel contribution is the integration of elder dependency rates, which limit housing turnover and exacerbate supply constraints. Findings indicate that rising full homeownership—particularly among older households—has reduced tenure mobility. The study also shows that CSAs offer a stronger analytical resolution than counties. Despite home …

Subway, Collaborative Matching, And Innovation, Yumi Koh, Li Jing, Jianhuan Xu

Research Collection School Of Economics

Using rapid expansion of the Beijing subway from 2000 to 2018, we analyze its impact on collaborative matches in innovations. We find that an hour reduction in travel time between a pair of locations in Beijing brought 14.85% to 37.69% increase in collaborated patents. Far-apart location pairs were more affected, and the local average causal response is approximately 34.92% to 82.29%. The effect is mainly driven by increased matches among highly productive innovators. The entry of new innovators, relocation of existing innovators, and collaborations among low-productive innovators also contribute to the increase in collaborative matches, especially in the long run.

Policymaking And Pretrial Fairness: Evaluating Illinois' Ban On Cash Bail Beyond Chicago, Kaitlyn M. Sims

Global and Public Affairs: Faculty Scholarship

Over 400,000 people are incarcerated awaiting trial each day in the United States. Many of these individuals are held because they are unable to post cash bail, generating substantial economic inequality between those who are able to be released and those who must wait. Illinois's Pretrial Fairness Act (PFA) banned cash bail in 2023 to reduce economic inequity and remove judicial discretion in pretrial decisions. I use daily roster data from multiple suburban and rural Illinois jails and a regression-discontinuity-in-time (RDiT) approach to test for changes to jail composition after the law went into effect. Jail population sizes decreased, though …

Utility-Scale Solar In Virginia – Current Trends And Future Impacts, Damian Pitt, Jennifer M. Ciminelli, Josie Laprad

L. Douglas Wilder School of Government and Public Affairs Publications

Electricity demand is soaring in Virginia, driven largely by the state’s booming data center industry. As the country’s cheapest source of new electricity supply, utility-scale solar (USS) is crucial to meeting this growing need.

Virginia has become a leading state for utility-scale solar development, and USS is projected to provide a substantial percentage of Virginia’s future electricity supply.

Concerns about the impacts of solar development, particularly on farm and forest land, is among the factors leading some localities to reject USS local land-use permits, and/or adopt more restrictive permitting regimes.

This trend towards more restrictive local permitting may threaten the …

The Economic And Environmental Impact Of Shinkansen And High-Speed Rail Infrastructure: A Comparative Analysis Of Economic Growth And Carbon Emissions Reduction, Dillan R. Victory

SPARK Symposium Presentations

The development of Japan's high-speed rail system, the Shinkansen, has played a pivotal role in the country's post-war economic resurgence. Introduced in 1964 with the Tokaidō Shinkansen, this transformative infrastructure investment significantly reduced travel times, bolstered economic activity around station hubs, and facilitated regional development by enabling urban decentralization. This paper explores the long-term economic benefits of high-speed rail, including its impact on land value, business expansion, and carbon emissions. The case study of the Linear Chuo Shinkansen, Japan's latest maglev project, underscores both the economic promise and the political resistance to expansion, particularly in regions such as Shizuoka.

Socio-Economic And Infrastructural Determinants Of Response Time Disparities Across Emergency Service Agencies, Alice N. Ottah

Electronic Theses & Dissertations (2024 - present)

This study comprehensively analyzes the determinants of disparities in emergency response times for EMS, Fire, and Police agencies in San Francisco from 2021 to 2023, utilizing a multilevel modeling framework and publicly accessible data. Contrary to a primary reliance on structural neighborhood factors, this research reveals that while neighborhood disadvantage statistically significantly interacts with agency type to influence response times, its direct effect is weak and not uniformly consistent across services. Specifically, the analysis demonstrates that variance in call response times across neighborhoods is minimal (Intraclass Correlation Coefficients < 0.02), the effects of disadvantage are agency-specific (null effects for Police and Fire), and even when significant (for EMS calls only), response times are faster in more disadvantaged neighborhoods. These findings challenge the existing literature on emergency response times and highlight the need for tailored policy interventions that consider both neighborhood context and agency-specific operations to promote equitable emergency response.
