Inflation is a sustained increase in the general price level of goods and services, which diminishes the purchasing power of money. It can take various forms, such as creeping, walking, running, and hyperinflation, and can arise from factors like demand-pull or cost-push dynamics. The effects of inflation are wide-ranging, impacting consumers, producers, and the overall economy, and necessitating various control measures from monetary and fiscal policies to supply-side strategies.
