We consider the problem of choosing an allocation in an economy in which there are one private good and one public good. Our purpose is to identify the class of procedures of choosing an allocation which satisfy "strategy-proofness," "individual rationality", "no exploitation" and "non-bossiness". Any such procedure is a scheme of "semi-convex cost sharing" determined by "the minimum demand principle".
