%0 Journal Article %A Corey White %T Measuring Social and Externality Benefits of Influenza Vaccination %D 2021 %R 10.3368/jhr.56.3.1118-9893R2 %J Journal of Human Resources %P 749-785 %V 56 %N 3 %X 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. %U https://jhr.uwpress.org/content/wpjhr/56/3/749.full.pdf
