The overprovision anomaly of private public good supply

It is well known that private provision of a public good may lead to a high er supply than that in some Pareto optimal allocation. The traditional view attributes this "overprovision anomaly" to a specific kind of preferences. The present paper, however, show's that preferences do not play a decisive role. Assuming normality, overprovision will occur only if the distributio n of income is extremely skewed and Pareto optimal allocations are not with in the set of cost-share equilibria.
