Two nations can produce computers and software in the amounts given in the table above

Does either nation have an absolute advantage in producing the products? Which nation has a comparative advantage in computers? Which nation has a comparative advantage in software? Explain your answers.

Nation B has an absolute advantage in producing both goods because it can produce more of both in one day than can Nation A. Nation B has the comparative advantage in computer production and Nation A has the comparative advantage in software. The nation with the lowest opportunity cost of producing a good has the comparative advantage in that good. In Nation A, to produce 100 computers has the opportunity cost of 140 units of software forgone, so the opportunity cost of 1 computer equals (140 units of software)/(100 computers) = 1.4 units of software per computer. In Nation B, similar calculations show that the opportunity cost for a computer is 1.25 units of software per computer. Nation B's opportunity cost is lower, so Nation B has the comparative advantage in computers. For software, in Nation A the opportunity cost of a unit of software is (100 computers)/(140 units of software) = 0.71 computers per unit of software while in Nation B the opportunity cost is (120 computers)/(150 units of software) = 0.80 computers per unit of software. Nation A's opportunity cost is lower, so Nation A has the comparative advantage in software.
