First things first, we can all agree that our WANTS ARE UNLIMITED, you may tell yourself otherwise but the fact that you have 5 old phones at home and 200 pairs of trainers tells another story ;)
Now how is this related to economics you may ask? Well economics only exists because the wants of society are never-ending, and clearly, SOME PEOPLE'S WANTS ARE MORE ABLE TO BE SATISFIED THAN OTHERS, but WHY CAN'T ALL WANTS BE SATISFIED?
...the answer to this question is related to the fact that most of these UNLIMITED WANTS require PRODUCTIVE RESOURCES to be used, however, these RESOURCES ARE LIMITED.
The productive resources that an economy possesses can be categorised into 4 factors, AKA 'The factors of production':
1. LAND: This factor refers to the natural resources needed in production and includes, rivers, lakes, coal deposits, timber etc...
2. LABOUR: This factor refers to the human resources, needed in production such as factory workers, and doctors....
3. CAPITAL: This factor refers to man-made aids/tools used in the production process. They are often referred to as 'Capital goods' and when combined with land and labour produce more units of output.
4. ENTREPRENEUR: This factor carries out two functions. First, the enterprise factor organises the other three factors of production. Second, enterprise involves taking the risk of production, which exists in a free enterprise economy.
With UNLIMITED WANTS + LIMITED PRODUCTIVE RESOURCES, we have a situation called 'SCARCITY'.
As such we can say that due to scarcity, CHOICES about how these limited resources are used ('ALLOCATED') must inevitably be made.
Thus every economy must find ways to answer THREE ECONOMIC QUESTIONS.
Q. Are people willing to pay for it? YES!
Q. Is there sufficient quantity to satisfy all demand at zero dollars? NO!
Q. Does its use create an opportunity cost? YES!
Q. Does it use scarce resources to make? YES!
EXAMPLES:
I-PHONE
COCA-COLA
OFS
