What is inflation and what causes it?
الإجابة المختصرة
Inflation is a sustained rise in the general price level, which means each unit of money buys less. It is usually measured by the change in a consumer price index over a year. The two main causes are demand-pull inflation, when total demand grows faster than the economy can produce, and cost-push inflation, when production costs such as wages, fuel or imports rise.
خطوة بخطوة
- Define inflation as a sustained rise in the general price level.
- Explain demand-pull: too much spending chasing too few goods.
- Explain cost-push: firms pass higher costs on to consumers.
- Mention expectations: if people expect prices to rise, they ask for higher wages, which pushes prices up.
- Name the usual policy response: higher interest rates set by the central bank.
