Scarcity
• Society has unlimited wants
• Economic resources are scarce
Economic Resources include:
• land – all gifts of nature
• Labor – all physical and mental talents
• Capital – manufactured aids used in producing
goods and services
• Entrepreneurial ability – takes initiative and risk
Opportunity Cost
• what must be given up in order to get something
Production Possibilities Model
• Graphic representation of opportunity cost
•
Each point on the curve represents some
maximum output of two products
Law of increasing opportunity cost –
• the more of a product that is produced, the greater its
opportunity cost
• Shape of the curve illustrates the law
Guns and butter is a
classic economics
comparison. Guns
represent capital
goods and butter
represents consumer
goods.
Production possibilities curve may shift if:
• Increase in
resources
• Advances in
technology

Assume the economy
represented is presently
producing 12 units of Good B
and 0 units of good A.
1. The opportunity cost of increase production of Good A from 0
units to 1 unit is the loss of _____________ unit(s) of Good B.
2. The opportunity cost of increasing production of Good A from 1
unit to 2 units is the loss of ________ units(s) of Good B.
3. The opportunity cost of increasing production of Good A from 2 units to 3 units is the loss of
______ unit(s) of Good B.
4. This is an example of ________________ opportunity cost per unit for Good A.
Assume the economy
represented is presently
producing 12 units of Good B
and 0 units of good A.
1. The opportunity cost of increase production of Good A from 0
units to 1 unit is the loss of
2 unit(s) of Good B.
2. The opportunity cost of increasing production of Good A from 1
unit to 2 units is the loss of
2 units(s) of Good B.
3. The opportunity cost of increasing production of Good A from 2 units to 3 units is the loss of
2
unit(s) of Good B.
4. This is an example of constant opportunity cost per unit for Good A.
