The paper illustrates a multisector econometric model for the Federal Republic of Germany. A new model concept has been realized in two respects. First the model combines a disaggregated real system with a disaggregated monetary system. Second, both systems are disaggregated functionally (commodities) and institutionally (industries). This demands a specific theoretical structure and an appropriate database.; First a synopsis of the theoretical structure of the model is given. Afterwards an ex post solution of the model is discussed, which shows that the system works. Finally a simulation examines which effects a fall of the dollar has on the structure and the level of production and employment in the Federal Republic of Germany.
