Plans,disequilibria and macroeconomic policy simulations

In the paper some specific problems of applying a disequilibrium model of a centrally planned economy for policy simulation experiments are analysed. It is shown that a model in which demand, supply and plan output variables are simultaneously introduced can be used for policy simulation in a more effective way than a model which describes either demand or supply side of an economy. In the empirical part of the paper a disequilibrium-type model of the Polish economy is used for simulating alternative internal and external economic policies for 1971–80. It has been found that internal deflationary policies would have been relatively efficient in minimizing consumption excess demand at a given level of consumption output in the period investigated.
