10. THEORY OF COMPARATIVE ADVANTAGE  David Ricardo – Countries can gain from trade even if one nation has an absolute advantage in production of two goods.  Comparative Advantage – One nation has a lower opportunity cost in the production of a good than another nation.

11. The global allocation of resources improves because production by less efficient producers is reduced and replaced by more efficient producers.

12. Is comparative advantage faulty in theory?  Resources are immobile – factors of production are fixed  Technology is fixed  Resources are fully employed  Perfect competition  There is a balance in exports and imports  Free trade  Consideration of transportation  What about structural changes in an economy?  Can there be too much specialization?  What about agriculture and price fluctuations?
