Grade 8 Economics- Chapter-1, Basic economic problem

Chapter: 1

The Basic Economic Problem

Scarcity means that economic resources are not enough to completely satisfy our wants. Scarcity arises because human wants are unlimited and economic resources are scarce.

All the scarce materials found on the earth are called resources. These include natural resources, machinery, people and so on.

Why are resources important?
Resources are important because they are used to make goods and services to satisfy human wants.

Unlimited wants.
Human wants are unlimited. They are always growing and changing. When we satisfy one want another one will come up.
These are things that satisfy our wants. Goods are made with scarce resources.

Part of a nation’s resources is used to produce services that people want to consume as well as goods. E.g. Education, health, transport, communication, hotel, catering, tourism, entertainment etc.

Needs and wants:

Wants are goods and services that are not necessary for our survival, they give us pleasure. Example TV, motorcars, telephone etc.

Needs are the goods and services that are necessary for our survival.
Example: Food, clothing, house, medicine etc.

Free goods:
Free goods are goods that are unlimited in supply. They are not scarce goods. They have no opportunity cost. Example: ice at the North Pole, sand in a desert, air.

Economic goods:
Economic goods are scarce goods. These are the goods and services that are produced by using the scarce economic resources.

Wealth and income
The real wealth of a nation consists of its capital like roads, railways, houses, factories, machines and other stock of capital goods available to use or consume in the future.
The real income of a nation consists of goods and services produced by its resources over a given periods of time.
Thus, wealth is essentially a stock of goods that has been accumulated , where as income is a flow of both goods and services measured over time.

People cannot find enough resources to satisfy all their wants and needs, so they must choose the most urgent wants and satisfy them first. This is called choice.
Choice involves an opportunity cost.

Why is choice necessary?
Choice is necessary because resources have alternative uses.


Scarce Resources have Alternative uses:
Below is a list of resources. See how many alternative uses you can find for them, that is, see how many different goods and services they can help to produce.
1. An area of farmland.
2. A person who is good at Mathematics.
3. A shovel.
4. An egg.

Opportunity cost: The cost of choice

Human wants are unlimited and economic resources are scarce. Therefore we have to make choice. When we make a choice something has to be given up or sacrificed. The thing that we give up is the opportunity cost of what we have chosen.
Example: Ahmed has just enough money to buy either a coca cola or an ice cream. He chooses the ice cream. His opportunity cost is the coca cola that he gave up.

Opportunity cost arises not only when we buy things, but also when we choose what goods and services we produce.
For example, in deciding to use a piece of land to build a new sports complex, we may be going without the benefit new houses.


The Next Best Thing
Choosing between goods and services involves a very special cost . Now imagine that you were unable to get any of these items. Copy and complete the table.

What have I just bought
What could I have bought instead?

Compact disc.

Four bed room house

Box of chocolates.

A ticket to the cup final

In the second column you have listed your second best choices, or your next best alternatives. For example, if you had bought the compact disc player, you may be going without the benefit of a record -player. The benefit of the record player given up is the real cost of owing the compact disc player .The real cost of choosing one thing and not another is known as the opportunity cost. This measures the benefit you could have had from the next best alternative you have gone without.

1.3 Implications of particular courses of action in terms of opportunity cost.

Opportunity cost arises not only when we buy things, but also when we choose what goods and services to produce. For example, in deciding to use a piece of land to build a new sports complex, we may be going without the benefit of new houses.


If there were enough resources to produce everything everybody wanted, would there be any opportunity cost? Explain your answer.

1.4 Production, consumption and exchange

All the economic activities can be classified into three groups. They are production, consumption and exchange:

Production means producing goods and services to satisfy human wants.

Producer: The people who make and sale goods and services are known as producers.

This describes the using up of goods and services in order to satisfy our wants.
A person who uses up goods and services

Consumer goods:
Goods, which are wanted for their own sake because they provide immediate satisfaction.
Example: food, clothing, a household’s furniture, a family car etc.

Durable consumer goods:
These are the consumer goods that have a fairly long life. Many of them last for several years.
Example: TV, table, chair.

Non-durable consumer goods:
These are the commodities, which are used up immediately or in a short period of time. Some of these are single use goods. Example: food, soap, toothpaste etc.

Consumer services:
These include the services that we use in modern life.
Example: transport, entertainment communication, legal, education, and health services, etc.

Exchange is the act of buying and selling goods and services either in the form of barter or through a market.
The modern system of exchange depends upon the use of money. We sell our goods and services for money and then use this money to buy the goods and services that others have produced.
