Inflation is defined as a sustained increase in the general price level in an economy. It occurs when there is too much money chasing too few goods, as explained by Coulborn. There are different types of inflation classified by speed, from creeping inflation of around 2% annual price increases up to hyperinflation with no limit to price growth. The main causes are an increase in the money supply or credit in an economy. Inflation can be addressed through monetary policy measures like raising interest rates, or fiscal policy steps like increasing taxes and reducing government spending.
