Search the web or Library databases to find two credible sources that examine the concept of comparative advantage, either in a theoretical or case study context.
In your first post to the Discussion Forum (2-3 paragraphs), describe what each source argues about comparative advantage, and provide an analysis of any differences of opinion or perspective between the two sources.
Does either source (or both) describe or cite circumstances under which comparative advantage is difficult to obtain or does not play out as traditionally theorized? If so, explain these differences and summarize any associated issues. If not, explain how your sources illustrate the role and importance of comparative advantage in the global economy.
Your response should cite at least two credible sources. Here are links to valuable CSU-Global Library Guides to help you find appropriate sources:
