1. Meaning of Inflation

• Inflation: Sustained rise in the general price level of goods and services.
• Measured as a percentage change in a price index.
• Indicates a decline in the purchasing power of currency.
• Opposite situation: Deflation (persistent fall in price level).

2. Types of Inflation

A. Demand-Pull Inflation

Occurs when Aggregate Demand (AD) > Aggregate Supply (AS).

Causes:

• Increase in money supply
• Rise in exports (currency undervaluation)
• Excess consumption demand
• Government deficit spending

Mechanism:
Higher demand → Demand-supply gap → Rise in prices

B. Cost-Push Inflation

Occurs when the cost of production increases, reducing aggregate supply.

Causes:

• Rise in wages
• Increase in raw material prices (e.g., crude oil)
• Supply bottlenecks
• Hoarding / artificial scarcity
• Increase in freight costs
• Exchange rate depreciation

Mechanism:
Higher input cost → Reduced supply → Higher prices

3. Factors Causing Inflation

Demand Side Factors

• Excess money supply
• Credit expansion
• Increase in exports
• Government deficit
• Rise in disposable income

Supply Side Factors

• Shortage of labour, land, and capital
• Increase in global commodity prices
• Poor agricultural output
• Hoarding and black marketing
• External shocks

4. Measurement of Inflation in India

Inflation is measured through price indices.

A. Consumer Price Index (CPI)

• Measures retail-level price changes.
• Includes:
  • Food
  • Medical care
  • Education
  • Housing
  • Transport
• Reflects the cost of living
• Used by RBI for inflation targeting.

B. Wholesale Price Index (WPI)

• Measures wholesale-level prices.
• Captures goods sold between businesses.
• Does not include services.

In India, both CPI and WPI are used.

5. Effects of Inflation on the Economy

Negative Effects

• Decline in purchasing power
• Increase in the cost of living
• Reduced savings value
• Loss of international competitiveness
• Economic uncertainty
• Lower investment
• Slower economic growth

Positive Effects (Moderate Inflation)

• Encourages spending
• Discourages hoarding
• Promotes production and investment

6. Inflation Targeting in India

Institutional Framework

• Inflation is measured by the Ministry of Statistics and Programme Implementation (MoSPI)
• Controlled by RBI through the Monetary Policy Committee (MPC)

Target

• CPI inflation target: 4%
• Tolerance band: 2%–6%
• Introduced in 2016

RBI uses:

• Repo rate
• Reverse repo rate
• Bank rate
• Open Market Operations (OMO)

7. Pros and Cons of Inflation Targeting

Pros

• Transparency and accountability
• Anchors inflation expectations
• Avoids boom-bust cycles
• Encourages macroeconomic stability
• Reduces uncertainty

Cons

• May ignore unemployment
• Less policy flexibility
• Cannot solve supply shocks
• Cannot fix structural bottlenecks
• Growth may slow in the short run

8. Methods to Control Inflation

A. Monetary Policy

• Increase repo rate
• Reduce the money supply
• Open Market Operations
• Increase CRR/SLR

Used mainly for demand-pull inflation.

B. Fiscal Policy

• Increase taxes
• Reduce public expenditure
• Cut the fiscal deficit

Limits private spending.

C. Price Control

• Fixing maximum prices
• Short-term relief only

D. Supply-Side Measures

• Increase MSP to boost production
• Buffer stock operations
• Price Stabilization Fund
• Control hoarding (Essential Commodities Act)
• Import essential goods

9. Government Steps to Control Inflation

• Action against hoarding and black marketing
• Enforcement of the Essential Commodities Act
• Creation of buffer stock (e.g., pulses)
• Price Stabilization Fund
• Stock limits on onions
• Market intervention schemes
• Regular price monitoring committees

Quick Revision Pointers

• CPI is used for inflation targeting.
• Inflation target = 4% ± 2%.
• WPI does not include services.
• Demand-pull: Aggregate Demand > Aggregate Supply.
• Cost-push: Increase in production cost.
• Moderate inflation is desirable.
• Deflation is rare and dangerous.
• Inflation reduces the real value of savings.
