Religion and prosociality across the globe
In this paper we analyze newly available, globally representative data on preferences and world religions (Christianity, Islam, Hinduism, Buddhism and Judaism). We find that individuals who report believing in such religions also exhibit more prosocial preferences, as measured by their levels of positive reciprocity, altruism and trust. We further document heterogeneous patterns of negative reciprocity and punishment across world religions. The association between religion and prosocial preferences is stronger in more populous societies and weaker in countries with better institutions. The interactive results between these variables point towards a substitution effect between religious and secular institutions, when it comes to prosocial preferences.
