How Bumble-Bees Fly: Accounting for Public Interest Participation

Abstract
This paper confirms the existence of public interest groups as a theoretical puzzle for an Olson type (economically-driven) rational choice explanation. It systematically reviews different theoretical approaches that challenge this appearance of paradox. The paper also introduces some British survey data. It concludes that rational choice analysis must subsume non-material incentives, but shows that discussions predicated on conceptions of rationality other than that used by Olson do not imply that participation is a problem to be explained. It also points to the importance of group activity in shaping the preferences of potential members and in stimulating membership.
