Publications

"The Hawaii Housing Factbook 2025" (with Justin Tyndall, Rachel Inafuku, JoonYup Park, Jack Driggers, and Emi Kim), University of Hawaiʻi Economic Research Organization, May 2025.

Considers the extent and nature of Hawai‘i’s housing affordability challenges and their impact on residents across the state. Shows that rising housing costs continue to place significant financial strain on many households, making homeownership and stable housing increasingly difficult for a large share of the population.

"An Economic Analysis of the Proposal to Phase Out Transient Vacation Rentals in Maui County Apartment Districts" (with Carl Bonham, Steven Bond-Smith, Peter Fuleky, Justin Tyndall, Dylan Moore, Emi Kim, and Hamza Essaidi), University of Hawaiʻi Economic Research Organization, March 2025.

Assesses the potential effects of phasing out transient vacation rentals in Maui County apartment districts on housing availability and the local economy. Finds that restricting these vacation rentals could increase the supply of housing available to residents while also creating economic tradeoffs for businesses, workers, and government revenues connected to tourism.

"The Vulnerability of Hawai‘i’s Nonprofit Sector to Cuts in Federal Funding" (with Jack Driggers), University of Hawaiʻi Economic Research Organization, October 2025.

Examines how reductions in federal funding could affect nonprofit organizations across Hawai‘i and the communities they serve. Demonstrates that many nonprofits rely heavily on federal support and could face significant challenges in maintaining services if that funding is reduced, potentially affecting vulnerable populations throughout the state.

"Construction Defect Litigation, Housing Affordability, and Homeownership in Hawaiʻi" (with Justin Tyndall, Kimberly Burnett, Emi Kim, and Kaila Ronquilio), University of Hawaiʻi Economic Research Organization, March 2025.

Investigates how construction defect litigation may affect housing development, housing affordability, and opportunities for homeownership in Hawaiʻi. Suggests that legal risks and costs associated with construction defect claims can discourage housing development and contribute to higher housing prices, potentially limiting access to homeownership.

"The Prospects of Artificial Intelligence in Urban Planning" (with Thomas W. Sanchez, Hannah Shumway, and Theo Lim). International Journal of Urban Sciences 27, no. 2 (2023): 179–194.

Explores how artificial intelligence can be used to address challenges in urban planning and support decision-making in cities. Highlights the potential of artificial intelligence to improve planning processes, analyze complex urban issues, and help policymakers make more informed decisions, while also recognizing the importance of addressing practical and ethical concerns.
