" For fiscal policy, the appropriate counterpart to the monetary rule would be to plan expenditure programs entirely in terms of what the community wants to do through government rather than privately, and without any regard to problems of year-to-year economic stability; to plan tax rates so as to provide sufficient revenues to cover planned expenditures on the average of one year with another, again without regard to year-to-year changes in economic stability; and to avoid erratic changes in either governmental expenditures or taxes.
