What is Inflation?
Inflation is defined as a general increase in the prices of goods and services, and a fall in the purchasing power of money. Most developed nations try to sustain an inflation rate of around 2-3% through fiscal and monetary policy.
Hyperinflation
Excessive inflation that rapidly erodes the real value of a currency. Examples include Germany in the 1920s and Zimbabwe in the 2000s, where prices doubled every few days.
Deflation
The general reduction of prices. While it sounds good, it often leads to a "deflationary spiral" where consumers stop spending, leading to economic stagnation.
Why Inflation Occurs?
Cost-Push
When the cost of production (like oil or wages) goes up, businesses must raise prices to maintain profit margins.
Demand-Pull
When demand for goods/services exceeds an economy's ability to produce them, prices rise as buyers compete.
Built-in
Past inflation creates expectations of future inflation, leading workers to demand higher wages, which in turn raises prices.
