Peter J. Boettke/Joshua C. Hall/Kathleen M. Sheehan: Was Adam Smith right about religious competition?

Adam Smith famously argued that increased competition in religion would result in more religious tolerance and that the benefits of competition in the marketplace would also be seen in religious instruction when many religious sects are tolerated. We use a cross-section of a maximum of 167 countries to explore whether increased religious competition results in less governmental regulation of religion and less governmental favoritism of religion.
