Step 1: Understanding the Concept:
Inflation is a sustained increase in the general price level of goods and services in an economy over a period of time, which reduces the purchasing power of money.
Step 2: Causes of Inflation:
Demand-Pull Inflation: Occurs when the total demand for goods exceeds the total supply ("too much money chasing too few goods").
Cost-Push Inflation: Occurs when production costs (like wages or raw materials) rise, forcing producers to increase prices.
Monetary Growth: An excessive increase in the money supply by the central bank.
Step 3: Effects of Inflation:
Reduces Purchasing Power: People can buy fewer goods with the same amount of money.
Hurts Fixed-Income Groups: Pensioners and salaried workers suffer as their income doesn't rise as fast as prices.
Encourages Hoarding: People buy goods now to avoid higher prices later, causing artificial shortages.
Step 4: Final Answer:
Inflation is caused by excess demand or rising costs and results in the erosion of the value of money.
