This study is to empirically and theoretically investigate how peer effects play in vaccination decisions of individuals using a model of privately provided public goods. Using the data set regarding the vaccination behavior of neighbors residing in the same block of Itoman city in Okinawa prefecture has peer effects on individual vaccination decisions. The second empirical result reveals that an inmate of the same house has peer effects on the vaccination decisions of cohabiters using the data set from online national survey.
