How to Improve the Availability of Unrelated Stem Cell Donors: Evidence from a Major Donor Registry

Understanding how to effectively cope with the availability of hematopoietic stem cell donors for confirmatory typing is important for stem cell donor registries and researchers alike. The uncertain time horizon from enrolling to actually becoming a donor is a particular challenge for registries. This paper evaluates the impact of a set of initiatives aimed at improving stem cell collections and CT availability of donors at DKMS, one of the largest registries worldwide.

A subset of registered donors receive invitation letters to initiatives prior to an actual request for a stem cell donation. Donor ``retyping'' initiatives asked for a blood sample and more medical information, with a specific patient in the background (``patient-centered'' retyping) or without. Donor ``retention'' initiatives asked for notification of longer absence from home, as a commitment device. Exploiting the near-random allocation of initiatives to donors based on observable medical characteristics, we find evidence that the initiatives enhance the availability of donors when they receive an actual request. Patient-centered retyping initiatives are associated with a 5.9 percentage-point increase in availability on average, 5.0 percentage points higher than non-patient related initiatives. Retention initiatives with a ``team'' framing increase availability by 1.2 percentage points, which is 2.0 percentage points larger than a neutral frame that has a marginally negative impact. Participation in any of the initiatives predicts subsequent donor availability, whereas non-participation predicts unavailability only in retention initiatives. We discuss the implications of our findings for stem-cell donor registries.

Bad Lighting: Effects of Youth Indoor Tanning Prohibitions

Indoor tanning beds (ITBs) emit harmful UV light at high intensity and have been classified as carcinogenic to humans by the World Health Organization since 2009. In that same year, more one in three white high school girls reported using an indoor tanning bed in the prior year; by 2019 that figure had fallen to fewer than one in ten. We are the first to study the role of state laws prohibiting youths from indoor tanning on many tanning-related outcomes using difference-in-differences models and staggered adoption of ITB prohibitions across states. We find that youth ITB prohibitions reduced search intensity for tanning-related information and reduced self-reported indoor tanning participation and intensity among teen girls. We also find that youth ITB prohibitions significantly reduced the size of the indoor tanning market by increasing tanning salon closures and reducing tanning salon sales. We find little evidence of unintended consequences on other youth risky behaviors, and in fact we find evidence that youth ITB prohibitions increase sun protective behaviors. Our results demonstrate the effectiveness of youth ITB prohibitions and provide novel evidence on how public health policies affect private market outcomes.

An Examination of the Intracorrelation of Family Health Insurance

The onset of an individual-level health shock may result in non-trivial health insurance consequences for the family. This is because of the structure of US health care markets, where health insurance is often bundled at the family level and provided through an employer. Yet, relatively little is known about how the structure of bundled health insurance may amplify the effects of an individual-level health shock. Filling this gap, this study uses a large US medical claims dataset to examine how an isolated appendicitis emergency affects families’ health insurance outcomes.  Using coarsened exact matching and stacked difference-in-differences, this study finds that an acute appendicitis emergency leads to a 7-14 percent decreased likelihood of leaving the current health insurance network and health plan. This is primarily driven by reduced rates of job switching by the plan’s primary beneficiary. Furthermore, switching frictions stemming from the non-portability of health insurance products may contribute to the observed "health plan lock."
