Chapter 6 presents the supply side of the market using an approach parallel to that of the demand side of the market in Chapter 5. The chapter presents the material in a way that illustrates the second core principle of the textbook, that marginal benefits should equal marginal costs Chapter 5 presents the demand curve as derived from marginal benefit and Chapter 6 presents the supply curve as derived from marginal costs
