This is an excellent handout to prepare students for a class lecture on comparative advantage or as a reference for students after learning the concept.
The handout gives students a step-by-step approach to finding the comparative advantages of two countries with two different goods. The opportunity cost of each country for each good is calculated. Students will then be led through an analysis on which nation has a comparative advantage in what.
After that follows an intuitive explanation for students to understand comparative advantage on a logical level. See the product preview for an example.
There are two full examples, including calculations, analysis, and alternative explanations.
