Some people voluntarily provide public goods while others take a free ride. Are the providers acting rationally? Should they instead follow the example of the free-rider? What are the rational and moral justifications for voluntary provision? This dissertation examines five ways to justify voluntary provision: rational prudence, social norms, group agency, fairness, and altruism. It suggests that altruism provides the best possible defense. Considerations of fairness may also provide a justification in some circumstances, but generally this argument is vulnerable to the objection that free-riding is often a legitimate way of protecting oneself from exploitation by other free-riders. In places, the dissertation relies on simple game theoretic models and intuitive economic equilibrium notions to analyze public good situations. The dissertation closes with a discussion of the government's role in providing public goods. An argument is made that, for certain kinds of goods , the standard public goods argument is not appropriate to homogeneous populations. If this is correct, other justifications for governmental provision must be summoned for goods of this form
