2. Meaning of Inflation

Inflation is a continuous rise in the general price level of goods and services over a period of time, resulting in a decline in the purchasing power of money. :contentReference[oaicite:1]{index=1}

Features of Inflation

• General rise in prices.
• Reduction in purchasing power.
• Persistent and continuous process.
• Affects income distribution and savings.
• Measured through price indices.

3. Measurement of Inflation

Inflation is measured using price indices that track changes in prices over time. In India, the major indicators are Consumer Price Index (CPI) and Wholesale Price Index (WPI). :contentReference[oaicite:2]{index=2}

4. Types of Inflation

Based on Rate of Increase

• Creeping Inflation (Below 3%)
• Walking Inflation (3% - 10%)
• Running Inflation (10% - 20%)
• Galloping Inflation (Above 20%)
• Hyperinflation (Extremely high inflation)

Based on Causes

• Demand-Pull Inflation
• Cost-Push Inflation
• Imported Inflation
• Structural Inflation

5. Demand-Pull Inflation

Demand-Pull Inflation occurs when aggregate demand in the economy exceeds aggregate supply. Excess demand pushes prices upward. :contentReference[oaicite:3]{index=3}

Causes

• Increase in money supply.
• Rise in income and purchasing power.
• Increase in government expenditure.
• Rapid population growth.

6. Cost-Push Inflation

Cost-Push Inflation arises when the cost of production increases due to higher wages, raw material costs, taxes, or energy prices, causing firms to raise prices. :contentReference[oaicite:4]{index=4}

Causes

• Increase in wages.
• Rise in fuel prices.
• Higher taxation.
• Increase in raw material costs.

7. Other Important Terms

8. Effects of Inflation

Positive Effects

• Encourages investment.
• Promotes production and employment.
• Reduces burden of debt.

Negative Effects

• Reduces purchasing power.
• Increases inequality.
• Discourages savings.
• Creates economic uncertainty.

9. Control of Inflation

Monetary Measures

• Increase Repo Rate.
• Increase CRR and SLR.
• Open Market Operations.
• Credit control by RBI.

Fiscal Measures

• Reduction in government expenditure.
• Increase in taxes.
• Balanced budget policies.
• Encouraging production.

10. Business Cycle (Trade Cycle)

A Business Cycle refers to periodic fluctuations in economic activity around the long-term growth trend of an economy. It affects output, employment, income, and prices. :contentReference[oaicite:5]{index=5}

11. Characteristics of Business Cycle

• Recurrent in nature.
• Affects the whole economy.
• Involves fluctuations in output and employment.
• Not strictly periodic.
• Associated with optimism and pessimism in business activities.

12. Phases of Business Cycle

The classical business cycle generally moves through expansion, peak, contraction (recession), and trough before recovery starts. :contentReference[oaicite:6]{index=6}

13. Causes of Business Cycle

• Changes in investment.
• Technological innovations.
• Monetary and fiscal policies.
• Changes in consumer demand.
• International economic conditions.
• Natural disasters and political events.

14. Inflation and Business Cycle Relationship

• Inflation generally rises during expansion and prosperity.
• Inflation moderates during recession.
• Deflationary tendencies may appear during depression.
• Economic recovery increases demand and price levels.

15. Important BPSC Facts

• Inflation means a sustained increase in the general price level. :contentReference[oaicite:7]{index=7}
• CPI is the main indicator used for retail inflation measurement in India. :contentReference[oaicite:8]{index=8}
• Demand-Pull Inflation occurs due to excess demand. :contentReference[oaicite:9]{index=9}
• Cost-Push Inflation occurs due to rising production costs. :contentReference[oaicite:10]{index=10}
• Stagflation means inflation accompanied by stagnation and unemployment. :contentReference[oaicite:11]{index=11}
• Business Cycle consists of Expansion, Peak, Recession and Trough phases. :contentReference[oaicite:12]{index=12}

16. Quick Revision

1. Inflation = Sustained rise in general prices.
2. CPI, WPI and GDP Deflator are inflation measures.
3. Demand-Pull Inflation = Excess Demand.
4. Cost-Push Inflation = Rising Production Cost.
5. Deflation = Falling Prices.
6. Stagflation = Inflation + Unemployment + Low Growth.
7. Business Cycle = Expansion → Peak → Recession → Trough → Recovery.
