This paper presents an economic analysis of religious behavior that accounts for the continuing success of groups with strange requirements and seemingly inefficient prohibitions. The analysis does not presuppose any special motives for religious activity. Rather, religion is modeled as a club good that displays positive returns to "participatory crowding." The analysis demonstrates that efficient religions with perfectly rational members may benefit from stigma, self-sacrifice, and bizarre behavioral restrictions. The model also addresses sacrifice in nonreligious "social clubs": fraternities, communes, political parties, work groups, and families.

After a very long hiatus, economists have begun again to study the relationship between economics and religion. This article seeks to summarize and evaluate the principal themes and empirical findings that have appeared in some 200 recent papers on the economics of religion. Although some of the research concerns the economic consequences of religiosity, most applies standard economic theory to the study of individual religious activity, the characteristics of religious groups, and the impact of regulation and competition on religious markets.
