RT Journal Article SR Electronic T1 Measuring Social and Externality Benefits of Influenza Vaccination JF Journal of Human Resources JO J Hum Resour FD University of Wisconsin Press SP 749 OP 785 DO 10.3368/jhr.56.3.1118-9893R2 VO 56 IS 3 A1 White, Corey YR 2021 UL http://jhr.uwpress.org/content/56/3/749.abstract AB Vaccination represents a canonical example of externalities in economics, yet there are few estimates of their magnitudes. I estimate social and externality benefits of influenza vaccination in two settings. First, using a natural experiment, I estimate the impacts of aggregate vaccination rates on mortality and work absences in the United States. Second, I examine a setting with large potential externality benefits: vaccination mandates for healthcare workers. I find that the social benefits of vaccination are substantial, most of benefits operate through an externality, and the benefits of healthcare worker vaccination are particularly large.
