“…Our paper contributes to a growing literature connecting social norms to individual behavior, such as vaccination decisions or the observance of measures against the spread of infectious diseases (e.g., Agranov et al, 2021;Bargain & Aminjonov, 2020;Barrios et al, 2021;Bartscher et al, 2021;Ferwana & Varshney, 2021;Jung et al, 2013;Qiao et al, 2022;Reich, 2020;Zhang et al, 2022). Similarly to the act of contributing to a public good, the individual decision to get vaccinated contributes to the creation of herd immunity, which makes possible to protect the whole population from the disease, including those who cannot be vaccinated like newborns or those with compromised immune systems.…”
