“The role of money in the Soviet economy was limited by the fact that many consumer goods (housing, public transport, education, medical care) were basically allocated (or heavily subsidised) rather than sold at market prices. (Rents, fares and charges for medicines did exist, but they were relatively insignificant.) Because of this, and because of the fact that producer goods were rationed, money in the traditional model was not a universal medium of exchange. There were many things it could not buy.” Money Book:Socialist Planning Source: Socialist Planning
“According to Marxist–Leninist doctrine, the survival of money and financial flows in a socialist planned economy was something of an anomaly which would in due course disappear. Stalin assumed that in the higher phase of communism, when collective ownership would have disappeared and state ownership would have become universal, goods would circulate on the basis of direct product exchange (i.e. physical exchange without the intermediation of money).” Money Book:Socialist Planning Source: Socialist Planning
