Answer:
If you do everything better than anyone else, should you be self-sufficient and do everything yourself? Self-sufficiency is one possibility, but it turns out you can do better and make others better off in the process. By instead concentrating on the things you do the “most best” and exchanging or trading any excess of those things with someone else for the things that person does the “most best,” you can both be better off. Comparative advantage fleshes out what is meant by “most best.” It is one of the key principles of economics.
Comparative advantage is a powerful tool for understanding how we choose jobs in which to specialize, as well as which goods a whole country produces for export. Can one country produce everything so cheaply that other countries have no production options and no work opportunities for their citizens? Do large countries—which can produce more of everything—take unfair advantage of small countries when they trade?
Before reading about comparative advantage, you should review Exchange and Trade. After reading about comparative advantage, you may want to read about the Division of Labor and Specialization, about Globalization, Interdependence, and Local Trade, about Economic Growth, and about Barriers to Trade.
