Question

Quizplus · Accepted Answer

If Eileen has a comparative advantage over Jan in piano tuning but NOT in shoe polishing, it means that Jan may have a lower opportunity cost of shoe polishing. This is because comparative advantage refers to the ability to produce a good or service at a lower opportunity cost. So, it is possible that Jan could produce shoes at a lower opportunity cost than Eileen, even though Eileen has a comparative advantage in piano tuning. However, we cannot conclude anything about absolute advantage from the given information.
