Absolute Advantage
Adam Smith first developed the idea that international trade could be mutually
beneficial by allowing countries to exploit the opportunities of an
international division of labor. Any country may enjoy an absolute advantage
over others in the production of specific goods, and would benefit from trading
those goods in exchange for others in which its partner has an advantage. For
example, Great Britain has an absolute advantage in the production of cloth, and
Portugal enjoys a similar advantage in the production of wine; both countries’
welfare will improve by trading these commodities. This concept yields a narrow
view of the gains from trade, insofar as it fails to capture the benefits that
countries might enjoy even when one partner has an absolute advantage in the
production of all traded commodities. It is thus to be distinguished from the
more sophisticated notion of comparative advantage. (Note that while Smith used
the phrase “absolute advantage” at various points in The Wealth of Nations,
especially in his discussion of colonies, he did not mean it in the sense
employed here. The qualifier “absolute” was added by later commentators to
distinguish Smith’s conception from that of Ricardo.)
