Read the following chapters/sections in the textbook. These links work to take you to the online version of the textbook. Of the two chapters, chapter 2 in the textbook is more important and needs closer reading and attention. It introduces our first economic model: the production possibilities frontier, which then leads to concepts of comparative and absolute advantage. Comparative advantage is the basis of why people trade, whether it’s person-to-person trade or nation-to-nation trade. It will also be the subject of your first worksheet assignment. Because of that, I suggest you also skip ahead and read a portion of chapter 19. You’ll read all of that chapter in a later unit.
