9708.1.1 Scarcity Opportunity Cost Notes

SCARCITY

Definition: Scarcity refers to the basic economic problem where resources are limited but human wants are unlimited.

As a result, choices must be made and opportunity cost arises.

Basis of Scarcity:

Economic resources (land, labour, capital, enterprise) are limited.

Human wants are unlimited and recurring.

Not all wants can be satisfied at the same time.

Therefore, choice becomes necessary.

Scarcity faced by economic decision makers:

1

Individuals

Limited income but many wants.

 

Example:

A student chooses between a mobile phone and exam guide books.

2

Families

Limited household budgets.

 

Example:

A family chooses between a holiday and home renovation.

3

Firms

Limited factors of production.

 

Example:

A firm produces cars instead of bikes.

4

Government

Limited tax revenue.

 

Example:

More spending on healthcare instead of education

OPPORTUNITY COST: Definition: Opportunity cost is the next best alternative that is sacrificed when a choice is made.

Link between scarcity, choice and opportunity cost:

Scarcity leads to choice, and every choice involves an opportunity cost.

Examples of opportunity cost:

1

Individual

Buying a mobile phone instead of textbooks.

2

Household

Renovating a house instead of going on a holiday

3

Firm –

Producing laptops instead of tablets.

4

Government

Spending on defence instead of healthcare.

Exam conclusion: Because resources are scarce, every economic choice involves an opportunity cost.
