Abstract: | The principle of interacting between input-output and econometric systems is illustrated so that both final demands and gross outputs are treated as endogenous. Using a planned economy as an example, a model is constructed with an econometric accelerator and an input-output multiplier. Due to its special structure, the system solution is found with immediate formulas without matrix inverting. Necessary and sufficient conditions for solvability are formulated on the basis of the specific characteristics of the system's matrix. The results are interpreted in terms of familiar economic categories. |
