A theory of religious activity based on principles of supply-side economics has generated considerable controversy in the sociology of religion. This theory posits that religious pluralism increases rates of religious activity by promoting competition between churches. This paper tests (supply-side theory) with data describing US Mormons. Results uncover patterns in Mormon church activity that refute the theory. The paper outlines several characteristics ofMormonism that explain its deviance from the theorized outcome, and suggests a scope condition for supply-side theory.
