The Basics
Scare Resources
There are only a limited number of resources such as workers, machines, factories, raw materials etc. Yet there are a number of different ways in which they could be used. [pic]
Similarly people only have a limited amount of money. Yet they have lots of needs and wants to satisfy. [pic]
Also the Government has a limited amount of money £440 billion !!!!. However, it is unable to satisfy all its wants. [pic]
THE BASIC ECONOMIC PROBLEM – the problem arises because resources are scarce, but human wants are unlimited.

What is the difference between needs and wants?
choice and opportunity cost

Examples of Opportunity Cost
Allocation of Resources

• Coca Cola decide to spend £50 billion on advertising • The government decides to spend £100 billion on hospitals • An individual allocates their time to study rather than playing football
