关于此课程： The final module of the Power of Markets course begins by further exploring firm behavior in imperfectly competitive market settings: how firms with monopoly power can increase profits through price discrimination; and the price-output combinations we can expect firms to select in cases of monopolistic competition and oligopoly. We will also analyze monopolies from an efficiency perspective and look at the effects of imperfect information on firm and consumer behavior. We will next turn to exploring input markets and what determines the demand for an input by a firm, an industry, and the overall market. We will also look at the factors that affect input supply and how the supply of an input interacts with demand to determinant input prices. We will use input market theory to analyze institutions and government policies such as the NCAA sports cartel, the minimum wage, Social Security, and immigration. Finally, we will address the concept of market efficiency and what government can do to promote it as well as how government intervention may diminish it.
