At a very early stage of the Bolshevik experiment with economic planning it became obvious that the economy could not be made to function without the use of money and other financial instruments. In fact, a financial history of the Soviet economy would show a gradual but relentless expansion in the number and functions of financial instruments. This expansion has been gradual largely because Soviet economists, planners, and administrators have had both ideological (theoretical) and practical reservations about the appropriate uses as well as the potential abuses to which financial instruments can be put. The process has been relentless nonetheless, because for a number of essential economic functions the possible substitutes or alternatives to financial instruments are either impractical or nonexistent. Let me attempt to explain briefly the fundamental reasons for the ambivalence in Soviet financial policy.
