The policy that determines how much the government spends and what taxes citizens have to pay is called fiscal policy. Both help the government actively monitor and influence the country's economy. Governments use fiscal policy to contain recession and unemployment or to keep inflation in check. Most often, fiscal policy is used in conjunction with monetary policy. Monetary policy involves the use of interest rates and changes in the money supply to achieve relevant economic goals. The main objective of monetary policy is to keep inflation low and stable. But banks are also trying to support stability in economic growth.
