This paper considers the possible theoretical validity of the following "monetarist hypothesis": that a constant, positive government budget deficit can be maintained permanently and without inflation if it is financed by the issue of bonds rather than money. The question is studied in a discrete-time, perfect-foresight version of the competitive equilibrium model of Sidrauski, modified by the inclusion of government bonds as a third asset. It is shown that the monetarist hypothesis is invalid if the deficit is defined exclusive of interest payments, but that it is valid under the conventional definition. It is also shown that the stock of bonds can grow indefinitely at a rate in excess of the rate of output growth, provided that the difference is less than the rate of time preference. These formal conclusions do not take account of possible limitations on taxing capacity arising from default incentives that tend to grow with the stock of bonds.

Recent experience does not include a "monetarist experiment, " as some have argued, but may slightly reinforce preexisting reasons for doubting that the best way of formulating monetarist policy prescriptions is in the form of a constant growth rule for the money stock.A more desirable rule would pertain to the monetary base, which is much more directly under Fed control. While a constant base growth rule might provide good macroeconomic performance, better results should be obtainable from a rule that at regular intervals adjusts the base growth rate upward or downward depending on whether nominal GNP is below or above a target path that specifies constant, non-inflationary growth for that variable. This type of rule is activist, to an extent, but is non-discretionary.The implied absence of policy-making flexibility is desirable for reasons explained in the literature on dynamic inconsistency.
