Summary and Exam Tips for Inflation and Deflation
Inflation and Deflation is a subtopic of Government and the Macroeconomy, which falls under the subject Economics in the Cambridge IGCSE curriculum.
Inflation refers to the general and sustained rise in the price levels of goods and services over time. It is measured using indices like the Consumer Price Index (CPI), which tracks the average price changes of a basket of consumer goods and services. Inflation can be caused by demand-pull factors, where increased aggregate demand exceeds supply, or cost-push factors, where rising production costs lead to higher prices. Consequences include reduced purchasing power, less competitive exports, and losses for fixed-income groups and savers. Policies to control inflation include contractionary fiscal and monetary policies and supply-side measures.
Deflation, on the other hand, is the general fall in price levels. It occurs when aggregate supply exceeds demand, often during recessions, or due to increased productivity and technological advances. Deflation can lead to unemployment, reduced investment, and increased debt burdens. To counter deflation, expansionary fiscal and monetary policies are used, along with currency devaluation and managing inflation expectations.
