 Chapter 8: Building Blocks in Economics: The Problem of Choice

1. Economics – The word Economics comes from the Greek word Oikonomia.

Oikos = Household

Nemein = Management

Economics is the study of how limited resources are used to satisfy unlimited human wants.

Definition:- Economics deals with making the best use of scarce resources to satisfy unlimited needs and wants.

2. Needs and Wants

Needs:- Basic necessities required for survival.

• Food
• Water
• Shelter
• Clothing
• Healthcare

Wants:- Things that improve comfort and lifestyle.

• Mobile phones
• Cars
• Vacations
• Luxury items
• Gadgets

Difference

Needs                         Wants

• Essential                         Non-essential
• Limited                         Unlimited
• Necessary for survival Improve comfort

Human wants are unlimited and keep changing with time.

3. Resources:- Resources are factors used to produce goods and services.

Types

• Natural Resources (Water, Coal, Land)
• Human-made Resources (Capital, Machines, Technology)
• Resources are limited (scarce) but their uses are many.

Factors of Production

• Land
• Labour
• Capital
• Technology

4. Scarcity:-Scarcity means resources are limited while human wants are unlimited. Because of scarcity:

• Choices have to be made.
• Every choice involves a sacrifice.

5. Choice:- Since resources are scarce:

• Individuals choose how to spend money.
• Farmers choose which crop to grow.
• Governments choose where to spend public money.
• Businesses choose what to produce.

Formula:- Unlimited Wants + Limited Resources = Choice

6. Opportunity Cost:- Opportunity Cost is the value of the next best alternative that is given up while making a choice.

Examples

• Buying shoes instead of a mobile cover.
• Growing wheat instead of barley.
• Government building hospitals instead of highways.

Important:- Every economic choice has an opportunity cost.

7. Production Possibility Curve (PPC):- A graph showing different combinations of two goods that can be produced using available resources efficiently.

Features

• Shows maximum production.
• Shows trade-off.
• Downward sloping curve.
• Efficient use of resources.
• Helps in planning.

Example:- Farmer chooses between: Wheat, Barley

More barley = Less wheat.
