VOG: Using Volcanic Eruptions to Estimate the Impact of Air Pollution on Student Learning Outcomes

November 1, 2022

This study pairs variation stemming from volcanic eruptions from Kilauea with the census of Hawai‘i’s public schools student test scores to estimate the impact of particulates and sulfur dioxide on student performance. We leverage spatial correlations in pollution in conjunction with proximity to Kilauea and wind direction to construct predictions of pollution exposure at each […]

New publication in Journal of General Internal Medicine

June 16, 2022

A new publication led by UHERO’s Tim Halliday and Ruben Juarez describes how the federal government’s response to the COVID-19 pandemic created a perfect storm in which private laboratories can earn huge profits from PCR testing while potentially impacting health care premium costs. Halliday, T., Tan, C., Juarez, R. et al. Financial Implications of COVID-19 Polymerase Chain Reaction Tests on […]

Financial Implications of COVID-19 Polymerase Chain Reaction Tests on Independent Laboratories

June 9, 2022

During the COVID-19 pandemic, independent laboratories provided critically needed polymerase chain reaction (PCR) tests (Current Procedure Terminology Code: 87635) to identify positive COVID-19 patients. The Families First and Coronavirus Relief Act and CARES Act require commercial insurance plans to cover COVID-19 testing costs without any cost-sharing for patients, but do not set the price.1,2 Prior […]

Compact for care: how the Affordable Care Act marketplaces fell short for a vulnerable population in Hawaii

November 8, 2021

The Patient Protection and Affordable Care Act (ACA) was passed in 2010 to expand access to health insurance in the USA and promote innovation in health care delivery. While the law significantly reduced the proportion of uninsured, the market-based protection it provides for poor and vulnerable US residents is an imperfect substitute for government programs such […]

Intra-familial transfers, son preference, and retirement behavior in South Korea

October 1, 2021

Abstract: We consider the nexus of intra-familial transfers, the sex composition of the sibship, and parental retirement behavior in South Korea. To investigate this, we employ the Korean Longitudinal Study of Aging and a research design that relies on plausibly exogenous variation in the sex composition of the sibship. We provide evidence that it costs […]

Expanding Health Insurance for the Elderly of the Philippines

September 15, 2021

Abstract: This paper evaluates a Filipino policy that expanded health insurance coverage of its senior citizens, aged 60 and older, in 2014. We employ an instrumental variables estimator in which the first stage is a difference-in-differences specification that exploits the age discontinuity at age 60, along with data from before and after the policy. First stage […]

The Economics of Health and Migration

August 31, 2021

Abstract: Migration and health are intimately connected. It is known that migrants tend to be healthier than non-migrants. However, the mechanisms for this association are elusive. On the one hand, the costs of migration are lower for healthier people, thereby making it easier for the healthy to migrate. Empirical evidence from a variety of contexts shows […]

Intergenerational mobility in self-reported health status in the US

January 1, 2021

Abstract: We present estimates of intergenerational mobility in self-reported health status (SRHS) in the US using data from the PSID. We estimate that the rank-rank slope in SRHS is 0.26. We show that including both parent health and income in models of intergenerational mobility increases the explanatory power of child outcomes. We construct a monetary metric for […]

Congratulations to UHERO’s Timothy Halliday

November 21, 2020

Congratulations to UHERO’s Timothy Halliday on his new publication in the Journal of Public Economics, “Intergenerational mobility in self-reported health status in the US.” Halliday and his coauthors show that including both parent health and income in models of intergenerational mobility increases the explanatory power of child outcomes, and document striking health mobility gaps by […]
