Fiscal policy is most commonly viewed by economists as one-half of macroeconomic policy, the other half being monetary policy. In its most basic form fiscal policy describes how government funds its activities and what these activities are. The putting together of a government budget, for example, is fiscal policy. Fiscal policy is seen as sustainable or rational when the public and those buying government debt instruments perceive that a government’s fiscal policy is predictable and that the government will continue to make payments on its debt.
