Question

Suppose Spain produces only cars and trucks. The resources that are used in the production of these two goods are not specialized—that is, the same set of resources is equally useful in producing both trucks and cars. The shape of Spain’s production possibilities frontier (PPF) should reflect the fact that as Spain produces more trucks and fewer cars, the opportunity cost of producing each additional truck:
A. increases
B. decreases
C. remains constant

Answer 1

The correct answer is C. remains constant

If production costs for both are equal, then it is completely the same what the demand is great for, since the cost will always be the same for them. If people want 3 cars and 2 trucks, it will be the same as if they wanted 4 trucks and 1 car.
