Can political entrepreneurs solve the free-rider problem?

A solution of the problem of voluntary collective action, employing an improved concept of political entrepreneurship is proposed. This solution is consistent with large numbers of actors and pure public goods (joint production of private goods and asymmetry are not assumed). The importance of information imperfections in producing suboptimality in the provision of public goods is emphasized. Political entrepreneurship is made to parallel the Knightian concept of the entrepreneur, emphasizing the role of risk-taking and information collecting.
