Explanation
When the economy is close to full employment, the government must be cautious: an increase in government spending financed by borrowing (deficit spending) could push Aggregate Demand beyond the economy's full-employment capacity, causing an inflationary gap and demand-pull inflation. On the other hand, doing nothing may leave growth-enhancing public expenditure unutilised.
A balanced budget — where the increase in government spending (ΔG) is exactly matched by an equal increase in taxes (ΔT) — offers a middle path. According to the balanced budget multiplier theorem, even though taxes reduce disposable income and hence consumption (via the MPC), the full amount of government spending directly adds to aggregate demand, while the tax-induced fall in consumption is only a fraction (MPC × ΔT) of that. The net effect is that national income rises by exactly the amount of the increase in government spending — the balanced budget multiplier is always equal to 1, regardless of the value of MPC.
This makes a balanced budget especially useful near full employment, because it provides a controlled, moderate boost to income and employment without enlarging the fiscal deficit (since spending is tax-financed, not borrowing-financed) and without the risk of large, uncontrolled excess demand that deficit financing could cause.
