Prior to beginning work on this discussion forum, please read Chapters 6 through 8 of the course textbook.Explain the theory of factor mobility. Consider this theory, and create a trade agreement between two to four countries that does not already exist (you can use the Free Trade Agreements (Links to an external site.) web page to review U.S. trade agreements). Explain why this agreement would be beneficial to each country and how the theory of factor mobility connects to this trade agreement. Support your answer with at least one credible, recent source in addition to the course textbook. Your initial response should be 200 to 300 words.Guided Response: Respond to at least two of your classmates by commenting on their posts with constructive comments that move the conversation forward. Though two replies are the basic expectation for class discussions, for deeper engagement and learning you are encouraged to provide responses to posts by other students and to respond to any comments or questions from other students. In addition, responding to the instructor’s questions or comments is mandatory. Continuing to engage with peers and the instructor will further the conversation and provide you with opportunities to demonstrate your content expertise, critical thinking, and real-world experiences with the discussion topics.
