Budget Balancing
Tuesday, August 1st, 2006In December 1985, Congress passed a law-which it has since ignored-mandating a balanced budget by 1991. Is a zero deficit an appropriate target for fiscal policy?
The basic principles certainly do not lead to this conclusion. Instead, they point to the desirability of budget deficits when private demand, C + 1+(X - IM), is too weak and budget surpluses when private demand is too strong. The budget control should be done and the budget should be balanced, according to these principles, only when C + I + G + (X - IM) under a balanced-budget policy approximately equals full-employment levels of output. This may sometimes occur, but it will not necessarily be the norm.
In brief, according to this approach, the focus of fiscal policy should be on balancing aggregate supply and aggregate demand, not on balancing the budget. But why do these two criteria differ? The reason should be clear from our earlier discussion of stabilization policy.
Consider the fiscal policy that would be followed if we lived under an effective balanced-budget law. If private spending sagged for some reason, the multiplier would pull GNP down. Since personal and corporate tax receipts fall sharply when GNP declines, the budget would swing into the red. That would require either lower spending or higher taxes-exactly the opposite of the appropriate policy response. Thus:
Attempts to balance the budget-as done, say, by President Herbert Hoover during the Great Depression-will prolong and deepen recessions.
Budget balancing can also lead to inappropriate fiscal policy under boom conditions. If rising tax receipts induce a budget-balancing government to spend more or cut taxes, fiscal policy will “boom the boom”-with disastrous inflationary consequences. Fortunately, believers in budget balancing usually are not alarmed by surpluses.
Actually, the issue is even more complicated than we have indicated so far. Fiscal policy is not the only way the government affects aggregate demand. The government also influences aggregate demand through its monetary policy. For this reason:
The appropriate fiscal policy depends, among other things, on the stance of monetary policy. While a balanced budget may be appropriate under one monetary fund policy, a deficit or a surplus may be appropriate under another monetary policy.
An example will illustrate the point. Suppose Congress and the president believe that the aggregate supply and demand curves will intersect approximately at full employment if the budget is balanced. Then a balanced budget would seem to be the appropriate fiscal policy.
