An Alternative Algorithm for Identifying Free Riders Based on a No-Free-Rider Nash Equilibrium

In identifying the free riders in the voluntary provision of a pure public good, Andreoni and McGuire (1993) simplify Bergstrom, Blume, and Varian's (1986) algorithm by systematizing the selection process of potential contributors. We propose an alternative algorithm in which a concept of no-free-rider Nash equilibrium is utilized to identify potentially a large fraction of free riders in Nash equilibrium without conducting any Nash solution tests for them.
