An Effective Way of Teaching Comparative Advantage

PowerPoint Presentation

Comparative advantage is a powerful concept that usually appears in the second chapter of any intro-level economics class. However, many students struggle with this difficult concept. Comparative advantage is the basis of international trade. This conclusion is usually directly provided by the textbook, but it is not something students understand overnight. Therefore, it is necessary to help students explore why countries trade by showing them the evolution of international trade theories from Mercantilism, Adam Smith’s Absolute Advantage Model, and eventually David Ricardo’s Comparative Advantage Model.
