Answer:
Opportunity cost / relative advantage
Explanation:
Opportunity cost is one way of measuring the cost of a producer's choice of production. For example, if a producer chooses to produce soybeans, the opportunity cost is what he fails to earn if he produces another good, for example corn. In this way, opportunity cost is a relative measure of costs. If the opportunity cost for a producer to produce a good is lower than for another producer, this means that he has a comparative advantage in producing that good.
Having the comparative advantage over the production of a particular good is a good indicator for the productive choice. The country with a comparative advantage can specialize in the production of the good in question and profit from international trade through exports.
