What you must lock in for MCQs
- Scarcity creates the economic problem.
- Four central problems = What, How, For whom, Growth.
- Capitalism works mainly through the price mechanism.
- Socialism works mainly through central planning.
- Mixed economy uses a combination of both.
1. Basic / Central Economic Problem
Root Cause
- Human wants are unlimited.
- Resources are limited.
- Resources have alternative uses.
Result: These three together create scarcity, and scarcity creates the central economic problem.
Four Central Problems
- 1. What to produce?
- Which goods should be produced?
- How much of each good should be produced?
- Example: cars vs cloth, capital goods vs consumer goods
- 2. How to produce?
- Which technique should be used?
- Labour-intensive or capital-intensive
- Depends on availability and cost of factors
- 3. For whom to produce?
- Who will get the goods?
- How much will each person get?
- Depends on income and purchasing power
- 4. Provision for economic growth
- How much to consume now and how much to save for future?
- Important for future production capacity
2. Economic System
Meaning
- An economic system is the method by which production and distribution are organised in an economy.
Types of Economic System
- Capitalist economy
- Socialist economy
- Mixed economy
3. Capitalist Economy
Meaning

Key Features

How Problems Are Solved
- What to produce? Based on consumer demand and profit possibilities
- How to produce? By choosing the lowest cost technique
- For whom to produce? Based on income and buying capacity

How Problems Are Solved
- All basic problems are decided by the central planning authority.
- What to produce? Decided by government
- How to produce? Decided by the plan
- For whom to produce? Based on equal distribution objective
- Growth? Planned by the state
Merits
- Equality
- No exploitation
- Planned development
- Stability
Demerits
- No incentives
- Inefficiency
- Bureaucracy
- Limited freedom
5. Mixed Economy
Meaning
- Mixed economy is a combination of capitalism and socialism.
Features
- Co-existence of:
- Private sector

- Joint sector
- Government regulation plus market mechanism

Merits
- Balanced growth
- Social welfare with efficiency
- Reduced inequality
- Encourages innovation
Demerits
- Excess government control
- Inefficiency
- Corruption
- Difficulty in maintaining balance
6. Role of Price Mechanism
Meaning
- Price mechanism means prices are determined by demand and supply.
Role in Solving Basic Problems
- 1. What to produce?
- High demand leads to high price.
- High price encourages more production.
- 2. How to produce?
- Producers choose the lower-cost method.
- 3. For whom to produce?
- Goods go to those who have purchasing power.
Core Idea: Price mechanism works automatically, without central control, mainly in a capitalist economy.
