Chapter 1: Understanding Needs, Resources & Trade


 

🧠 Foundation Block for Indian Economy


🔑 Key Concepts

1. What is an Economy?

  • An economy is the system by which people earn their livelihood, produce goods and services, and exchange them to meet their needs and wants.

2. Types of Needs

  • Basic Needs: Food, water, shelter, clothes, education, health.

  • Other Needs: Transport, entertainment, internet, etc.

Needs are unlimited, but resources to satisfy them are limited. This creates the need for economic planning and decisions.


💡 Scarcity of Resources

  • Resources like land, water, minerals, money are limited.

  • Because of this scarcity, people and governments must choose how to use resources wisely — this is the central problem of an economy.


🔁 Choice and Opportunity Cost

  • If you spend ₹500 on a book, you can’t spend it on a movie. This is called opportunity cost.

  • Every choice in an economy involves a cost.


🔄 Types of Resources

Type Examples Description
Natural Land, rivers, forests Gift of nature
Human Labour, skills Productive efforts of people
Man-made (Capital) Tools, buildings Created by humans to aid production

🛒 Trade and Exchange

  • Barter System: Direct exchange of goods (used in ancient times).

  • Money Economy: Common medium of exchange — money.

  • Trade helps in specialisation and economic growth.

🔁 A fisherman trades fish for rice from a farmer — this is barter. But if the fisherman sells fish for money and buys rice — that’s monetised trade.


🌍 Why Trade Happens?

  • No one area has all resources.

  • Trade helps each region to get what they don’t produce and sell what they do.


📌 Summary

  • Human wants are unlimited, resources limited ⇒ Scarcity

  • People must choose, leading to opportunity cost

  • Resources: Natural, Human, Capital

  • Trade evolved from barter to money

  • Trade connects producers and consumers, promoting development
