As we saw in this chapter, comparative advantage is an important economic concept. We often use a table and some arithmetic to explain it, but how might you use words to explain comparative advantage to someone not taking this course, such as a roommate, a family member, or a friend? Hint: You might want to explain the concept using just two people or perhaps two businesses that trade goods and services with each other, where one is more efficient in the production of all goods and services and yet both benefit from trading with each other.
