On the existence of a Kantian solution of the public good problem

This paper questions the meaning and scope of the so-called kantian solution of the problem raised by the inefficiency of the voluntary provision of a public good. First and foremost, this solution is not truly kantian since if generally amounts to the philosophically well worn generalisation argument and injustifiably disregards important characteristics of the categorical imperative procedure. Morover, in any case, this "everyday Kantianism" fails as soon as individuals are not assumed identical. In fact no moral norm on ifs own can function asa perfect substitute for the coordination institution which is required to solve the public good problem. Finally, neither a "rule-paretian" system of morality nor true kantianism can remedy the situation although the latter may help to ensure the proper working of institutions specially designed to lead to efficient outcomes such as Lindahl-type processes.
