The theory of comparative advantage is perhaps the most important concept in international trade theory. As the economies that exist in our world our becoming increasingly more intertwined, it is becoming even more important. Nearly every country in the world depends on other countries to supply them with goods that they cannot produce in their own country. I believe that comparative in necessary in today's economy.

The countries should choose the product that they want to specialize in by which country had a comparative advantage in production. In order to identify a country's comparative advantage good, requires the opportunity cost to be identified.
Opportunity Cost refers to the "single most valuable opportunity given up when a choice is made, the opportunity cost is your next best alternative or your trade off"(www.richmond.edu).
