Publication: Vog: Using Volcanic Eruptions to Estimate the Impact of Air Pollution on Student Test Scores
We pair variation stemming from volcanic eruptions with the census of Hawaii’s public schools’ student test scores to estimate the impact of PM2.5 and SOM2 on student performance. Increased particulate pollution decreases test scores. These results are concentrated among schools with the highest long-term average levels of pollution. The effects of PM2.5 are larger for […]
Read MorePublication: Rural health disparities: Evidence from Hawaiʻi
This article examines how rurality contributes to health disparities in the Hawaiian Islands using data from the June 2023 wave of a statewide health survey. We analyze self-reported health outcomes alongside sociodemographic factors including age, gender, race/ethnicity, income, education, and disability. Our findings show that rurality is one of the strongest predictors of poorer health […]
Read MoreHow New Mass Transit Affects Labor Markets: The Honolulu Skyline
Understanding how the new rail system in Oahu is reshaping decisions around work, housing, and commuting can inform future transit investments. To get a more in-depth picture of how the Honolulu Skyline is influencing the labor market, I developed a spatial model with highly detailed data that allowed me to analyze commuting times, the employment […]
Read MoreScaling biocultural initiatives can support nature, food, and culture from summit to sea
Biocultural nature-based solutions provide many social, cultural, and ecological benefits. Yet, there has been little research on related land-sea societal benefits, hindering our ability to finance and scale these solutions. To help fill this gap, we evaluate the land-sea benefits of scaling biocultural restoration initiatives in Hawaiʻi, including multi-strata agroforestry and high-elevation silvopasture combined with […]
Read MoreNew Study Reveals Food Insecurity as a Major Driver of Mental Health Challenges in Hawaiʻi
A study published today in Frontiers in Public Health provides a comprehensive examination of how socioeconomic factors, particularly food insecurity, shape mental health outcomes among working adults in Hawaiʻi. The research, co-led by Ruben Juarez, the UHERO-HMSA Professor in Health Economics, and Binh Le, a Postdoctoral Researcher at the University of Hawaiʻi Economic Research Organization […]
Read MoreCarbon benefits through agroforestry transitions on unmanaged fallow agricultural land in Hawaiʻi
There are growing efforts to incorporate agroforestry into ecosystem service incentive programs. Indigenous and other place-based multi-strata agroforestry systems are important conservation and agricultural strategies, yet their ecosystem services, including carbon sequestration benefits, have received little research attention. To fill this gap, we draw on interviews with agroforestry practitioners and ecosystem service modeling in Hawaiʻi […]
Read MoreCo-Production of Knowledge at Sumida Farm Trains a New Generation of Community-Engaged Scientists
A collaboration between the University of Hawai‘i (UH), Hawai‘i Sea Grant, and the fourth generation of Sumida farmers focuses on training a new generation of locally engaged scientists. A key partner is UHERO, an interdisciplinary research group that informs public policy across Hawai‘i. The overarching goal is to build a healthy, resilient, and sustainable agricultural […]
Read MoreThreshold regressions for more objective urban and regional policies
Abstract: Achieving policy goals often requires different policies for different places, but the assignment of places to policies is often arbitrary, political, or based on anecdotal evidence. We argue that there are simple analytical techniques to improve policy by allocating places into corresponding ‘policy regimes’ in a more objective manner. We show how to implement […]
Read MoreMale-biased sex ratios, marriage, and household composition in early twentieth-century Hawai‘i
Abstract: Immigration to Hawai‘i between 1870 and 1930 led to a more than six-fold increase in population and high and rapidly varying sex ratios in the Chinese, Japanese, Korean, Filipino, and Caucasian populations of marriageable age. Using complete populations of the 1910, 1920, and 1930 Territorial Censuses of Hawai‘i, we estimate how male-biased ethnic sex […]
