Someone has a comparative advantage in producing a good when a) one has specific training in the production of that good. b) one's opportunity cost is constant. O o) one's opportunity cost of producing that good is lower than that of other producers. O d) one can produce more of the good than someone else using the same d) resources. O e) one enjoys producing that good.

Return to the example in Figure 2.4. Suppose there is an improvement in medical technology that enables more healthcare wilt line same amount of resources. How would this affect the production possibilities curve and, in particular, how would it affect the opportunity cost of education? Figure 2.4 Productive and Allocative Efficiency

Explain why societies cannot make a choice above their production possibilities frontier and should not make a choice below it.

What are the similarities between a consumers budget constraint and societys production possibilities frontier, not just graphically but analytically?
