Interdependence and the location of economic activities

This paper deals with the ability of a decentralized price system to sustain an optimal assignment of activities assuming complete interdependence among them. There are two goods, each of which is used in its own production and in the production of the other, along with land. An infinitely elastic final demand exists for both goods at given market prices, and either good may be imported. It is demonstrated that a decentralized price system will sustain an optimal allocation of land, and that a nonoptimal allocation of land will not be sustained.
