Subjectivism, joint consumption and the state: Public goods in Staatswirtschaftslehre

On the basis of F.B.W. Hermann's Staatswirthschaftliche Untersuchungen and of major German, Austrian and Swedish contributions to public economics, two specific claims with regard to the Germanic influence in the development of public expenditure theory are put forward in this paper. It is contended that the German achievements concerning the conceptual clarification of public goods are: (i) important as conceptual ingredients of the modern 'micro-based' theory of the public sector: (ii) less closely linked to some historical and intellectual German Sonderweg (culminating in historism, a collectivistic view of social entities and a mystical glorification of the State) than is often suggested. It is argued that these achievements rather were to a large extent inspired by the more cosmopolitan tendencies in German thought. An important influence is Kantian liberalism. Kant construed a kind of foundational interdependence between the public and the private sector. This prepares the ground for a framework of complementary institutions instead of explaining public institutions in terms of a market failure-perspective based on non-excludability: the view developed in German Idealism gives non-rivalry the pivotal role: the explanation of public institutions systematically hinges upon the existence of goods, the benefits of which are necessarily universal and hence are necessarily made available in a non-rival mode.
