Comparative Advantage: Input vs. Output

Comp. output - lowest opportunity cost (you give up less)
Comp. input - least effort to make 1 


For Comparative Advantage Output Questions:
  • The country that can produce the most, with similar resources as another country, has the absolute advantage.
  • Make opportunity cost comparisons.
  • The country with the lowest opportunity cost has the comparative advantage and will make that product.
  • Each country will seek a trade that is BETTER than their own domestic opportunity cost.  If they can’t do better in trade than they could produce on their own, then they don’t trade.
  • When each country trades, based on lowest opportunity cost, both can gain more in trade than they could produce domestically.  Therefore, they can “exceed” their own production frontiers.
For Comparative Advantage Input Questions:
  • The country that can produce a set amount of something by using the least resources, land, or time, has the absolute advantage.
  • Make opportunity cost comparisons by creating an “output” matrix first.  Do this by deciding for each product, what would be spent if a set unit was produced.
  • The country with the lowest output opportunity cost will, again, have the comparative advantage.
Trick for determining per unit opportunity cost
  • Output Question: "Other goes over"
  • Input Question: "Other goes under"
