The difference between production possibilities frontiers that are bowed out and those that are linear is that a. bowed out production possibilities frontiers illustrate tradeoffs where linear production possibilities frontiers do not. b. bowed out production possibilities frontiers show increasing opportunity cost where linear ones show constant opportunity cost. c. bowed out production possibilities frontiers are the result of perfectly shiftable resources where linear production possibilities frontiers are not. d. linear production possibilities frontiers illustrate real world conditions more than bowed out production possibilities frontiers.

The Production possibilities frontiers is a curve that shows the various combination of two goods a company can produce when all its resources are fully utilised.

The PPC is concave to the origin. This means that as more quantities of a product is produced, the fewer resources it has available to produce another good. As a result, less of the other product would be produced. So, the opportunity cost of producing a good increase as more and more of that good is produced.

Factors that cause the PPF to shift

1. changes in technology.

2. changes in available resources.

3. changes in the labour force.

a linear PPC means that there is a constant opportunity cost. Linear PPC are rear
