The author presents a neoclassical input-output-model for the Federal Republic of Germany, which is based on “make”- and “use”-tables instead of input-output-tables. The advantage of this approach is, that the model is able to discriminate volumes and prices for industries and commodities. The analytical frame-work gives economic hypotheses to explain the coefficients of “make”- and “use”-matrices. So a blended functional/institutional input-output-model can be constructed, which offers the opportunity to use different schemes for the disaggregation of final demand and primary inputs. The article describes the theoretical model and the numerical specification of an econometric model, which is based on it. At the end the results of an ex-post-projection with this econometric model are discussed.

The paper analyzes the commodity structure of exports and imports of nine industrialized countries, using a dynamic version of the Linear Expenditure System. The hypothesis implied by this approach is that the structure of commodity trade can be explained by a combination of habit persistence and constant marginal expenditure shares. Application of the model to the trade composition of nine countries shows that there are considerable differences in the strength of habit persistence across countries and across commodity groups as well as between exports and imports. These are crucial for the explanation of the associated expenditure and price elasticities.

Within this paper different demand systems are compared by means of test criteria for nested and nonnested hypotheses as well as by some information criteria like the Akaike and Schwatz information criterion.
