– Assumptions: • Full employment
• Use of the best technology available
• Productive efficiency

Scarcity – Represented by points outside the curve
Choice – Represented by points on the curve (efficient) and
points within the curve (inefficient)
Opportunity Cost – Represented by the downward slope of the curve

Law of Increasing Opportunity Costs
–Factors of production are not equally suitable
–As output increases, the per unit costs of additional units increases
–Gives the production possibilities curve its bowed out shape
