Causes of Inflation

Introduction

The causes of inflation are a fundamental topic in Economic Awareness, frequently asked in exams like SSC CGL, IBPS PO, and RRB NTPC. Understanding the different types of inflation and their causes helps in analyzing economic conditions and policy decisions.

Pattern: Causes of Inflation

Pattern

This pattern tests knowledge of the primary reasons behind inflation, including demand-pull and cost-push factors, and their economic implications.

Key Concept:

Inflation is the sustained increase in the general price level of goods and services in an economy over a period of time.

Important Points:

  • Demand-pull inflation = Caused by excess aggregate demand over aggregate supply.
  • Cost-push inflation = Caused by rising production costs, such as wages and raw materials.
  • Built-in inflation = Inflation resulting from adaptive expectations and wage-price spirals.

Step-by-Step Example

Question

Which of the following is a cause of demand-pull inflation?

Options:

  • A. Increase in wages leading to higher production costs
  • B. Excess demand in the economy over its productive capacity
  • C. Increase in import duties on raw materials
  • D. Reduction in money supply by the central bank

Solution

  1. Step 1: Understand demand-pull inflation

    It occurs when aggregate demand exceeds aggregate supply, causing prices to rise.

  2. Step 2: Analyze options

    Increase in wages and import duties are cost-push factors, while reduction in money supply reduces demand.

  3. Step 3: Identify correct cause

    Excess demand in the economy over its productive capacity directly causes demand-pull inflation.

  4. Final Answer:

    Excess demand in the economy over its productive capacity → Option B

  5. Quick Check:

    Demand-pull inflation = excess aggregate demand ✅

Quick Variations

This pattern may appear as questions on distinguishing between demand-pull and cost-push inflation, identifying causes of stagflation, or explaining built-in inflation mechanisms.

Trick to Always Use

  • Remember: Demand-pull = "Too much money chasing too few goods."
  • Cost-push = "Rising costs push prices up."

Summary

Summary

  • Demand-pull inflation arises from excess demand over supply.
  • Cost-push inflation results from increased production costs.
  • Built-in inflation is due to adaptive expectations and wage-price spirals.

Remember:
Demand-pull = excess demand; Cost-push = rising costs

Practice

(1/5)
1. Which of the following best describes demand-pull inflation?
easy
A. Inflation caused by government-imposed price controls
B. Inflation caused by rising wages and raw material costs
C. Inflation caused by a decrease in money supply
D. Inflation caused by an increase in aggregate demand exceeding aggregate supply

Solution

  1. Step 1: Identify the concept

    The question tests understanding of demand-pull inflation, a fundamental cause of inflation.

  2. Step 2: Apply the concept

    Demand-pull inflation occurs when aggregate demand exceeds aggregate supply, causing prices to rise. Rising wages and raw material costs relate to cost-push inflation. Decrease in money supply reduces inflation, and price controls do not cause inflation.

  3. Final Answer:

    Inflation caused by an increase in aggregate demand exceeding aggregate supply → Option D

  4. Quick Check:

    Demand-pull inflation = excess aggregate demand ✅
Hint: Demand-pull = too much money chasing too few goods.
Common Mistakes: Confusing demand-pull with cost-push inflation causes.
2. Cost-push inflation is primarily caused by:
easy
A. Excess demand in the economy
B. Increase in production costs such as wages and raw materials
C. Expansionary monetary policy
D. Decrease in aggregate supply due to technological improvements

Solution

  1. Step 1: Understand cost-push inflation

    Cost-push inflation arises when production costs increase, pushing prices up.

  2. Step 2: Analyze options

    Excess demand relates to demand-pull inflation. Expansionary monetary policy increases demand, not costs. Technological improvements usually increase supply, reducing inflation.

  3. Final Answer:

    Increase in production costs such as wages and raw materials → Option B

  4. Quick Check:

    Cost-push inflation = rising production costs ✅
Hint: Cost-push = rising costs push prices up.
Common Mistakes: Mixing cost-push inflation with demand-pull inflation causes.
3. Built-in inflation is mainly caused by:
easy
A. Adaptive expectations leading to wage-price spirals
B. Excess aggregate demand
C. Increase in import tariffs
D. Government subsidies on essential goods

Solution

  1. Step 1: Identify built-in inflation

    Built-in inflation results from adaptive expectations and wage-price spirals.

  2. Step 2: Apply the concept

    Excess demand causes demand-pull inflation. Import tariffs increase costs but relate to cost-push inflation. Subsidies usually reduce prices.

  3. Final Answer:

    Adaptive expectations leading to wage-price spirals → Option A

  4. Quick Check:

    Built-in inflation = wage-price spiral due to expectations ✅
Hint: Built-in inflation = wage-price spiral mechanism.
Common Mistakes: Confusing built-in inflation with demand-pull or cost-push types.
4. Which of the following scenarios is an example of demand-pull inflation?
medium
A. An increase in wages demanded by labour unions
B. A rise in crude oil prices increasing production costs
C. A sudden increase in government spending leading to higher aggregate demand
D. A supply chain disruption causing shortage of raw materials

Solution

  1. Step 1: Understand demand-pull inflation examples

    Demand-pull inflation occurs when aggregate demand rises sharply, pushing prices up.

  2. Step 2: Analyze options

    Government spending increases aggregate demand, causing demand-pull inflation. The other options relate to cost-push inflation due to rising costs or supply disruptions.

  3. Final Answer:

    A sudden increase in government spending leading to higher aggregate demand → Option C

  4. Quick Check:

    Demand-pull inflation = increase in aggregate demand ✅
Hint: Government spending increase often triggers demand-pull inflation.
Common Mistakes: Mistaking cost-push causes as demand-pull inflation.
5. Which of the following is NOT a cause of cost-push inflation?
medium
A. Excessive money supply in the economy
B. Rise in prices of imported raw materials
C. Increase in wages of workers
D. Higher taxes on production inputs

Solution

  1. Step 1: Identify causes of cost-push inflation

    Cost-push inflation is caused by rising production costs such as wages, raw materials, and taxes.

  2. Step 2: Analyze options

    Increase in wages, raw material prices, and taxes increase production costs causing cost-push inflation. Excessive money supply causes demand-pull inflation, not cost-push.

  3. Final Answer:

    Excessive money supply in the economy → Option A

  4. Quick Check:

    Excessive money supply causes demand-pull, NOT cost-push inflation ✅
Hint: Money supply affects demand-pull, not cost-push inflation.
Common Mistakes: Confusing monetary causes with cost-push inflation causes.
