Abstract
This paper unpacks the effects of social networks on county-level COVID19 vaccinations in the US. We jointly assess the contemporaneous and dynamic network ef-fects of vaccination exposure, to distinguish between network-mediated contemporane-ous effects (e.g., "vaccine-hunter" Facebook groups crowd-source information about ac-cess and efficacy) and longer-term effects (e.g., vaccine exposure chips away vaccine hesi-tancy). Accounting for possible correlated shocks, socio-economic/spatial confounders, and pandemic-related shifters, we find positive stage-of-pandemic dependent contempo-raneous friendship network effects, and null dynamic network effect, thus sharply dis-tinguishing COVID19 vaccination from other infection-mitigating practices in terms of openness to social-learning over time.
期刊介绍：
This Journal publishes articles on all aspects of health economics: theoretical contributions, empirical studies and analyses of health policy from the economic perspective. Its scope includes the determinants of health and its definition and valuation, as well as the demand for and supply of health care; planning and market mechanisms; micro-economic evaluation of individual procedures and treatments; and evaluation of the performance of health care systems.
Contributions should typically be original and innovative. As a rule, the Journal does not include routine applications of cost-effectiveness analysis, discrete choice experiments and costing analyses.
Editorials are regular features, these should be concise and topical. Occasionally commissioned reviews are published and special issues bring together contributions on a single topic. Health Economics Letters facilitate rapid exchange of views on topical issues. Contributions related to problems in both developed and developing countries are welcome.
