IntroductionUniversal Basic Income (UBI) policies have the potential to promote a wide range of public health objectives by providing those who qualify with direct cash payments. One overlooked mechanism of particular importance to health researchers is the possibility that guaranteed income might increase consultation of primary and preventive care (e.g., annual doctors' visits; regular vaccination against infectious disease) by providing people with both the time and monetary resources to do so, thereby improving general health.MethodsThis study assesses the effects of an exogenous shock to Alaska's UBI payments to all state residents: a 2022 decision to reclassify dividend "energy relief" provisions as nontaxable (thereby increasing payments by approximately $2,000 inflation-adjusted dollars). It estimates quasi-experimental treatment effects (in 2022 vs. 2021) via mixed linear probability models that compare pre/post policy change in primary care seeking behavior in Alaska vs. the US adult population; controlling for respondent-level fixed effects and state-level random effects. Data were collected in 2021-2022, and analyzed in 2024.ResultsThe likelihood that Alaskans sought primary care postreform (relative to beforehand) increased by 6pp, which was significantly greater than the same difference (2pp) observed across all other (non-UBI) US States (∆=4pp, p<0.01). The study provides suggestive evidence that comparatively fewer Alaskans had difficulty affording primary care during this period, with less-consistent evidence of increased flu vaccine uptake.ConclusionsEnhanced UBI payments ought to be thought about as a form of health policy, as they have the potential to advance a wide range of health objectives related to preventive care.Copyright © 2024 Elsevier Inc.
