Многопродуктовая модельная декомпозиция компонент валового внутреннего продукта России
The paper proposes methods of multiproduct decomposition components of GDP by use, allows the use of macroeconomic models several different price indices. The main distinguishing feature of the proposed decomposition is the lack of reference to the export or import, which solves the problem of incompatibility of the final system of equations and removes the restrictions on the behavior of export and import deflators. A theoretical basis for the procedures is provided, the method of calculating on the statistical data is described and the results of the procedure of decomposition on data on the components of Russia's GDP is presented. The resulting two-product decomposition is valuable not only as an intermediate step in the construction of macroeconomic models, but also allows a number of conclusions about the behavior of macroeconomic agents. The paper also provides a method of decomposition of changes in inventories, which, because of the nature of this indicator in economic models, are usually ignored.
