ABSTRACT:  A static partial equilibrium model is developed to examine how income affects people's childhood vaccination decisions. Assuming people are not too risk averse, the model shows that middle-income people vaccinate while low- and high-income people do not vaccinate and rely instead on medical treatment. This implies vaccination rates in a population may initially rise but start falling once the average income of the population exceeds a certain level.  Correspondingly, disease rates may initially fall but then start rising with the average income. These predictions are verified using individual- and county-level data from the U.S. and country-level data from the WHO.
