Inequality and Institutions in 20th Century America Abstract We provide a comprehensive view ofwidening income inequality in the United We States contrasting conditions since 1980 with those in earlier postwar years. argue that the income distribution in each period was strongly shaped by a set ofeconomic institutions. The early postwar years were dominated by unions, a negotiating framework set in the Treaty ofDetroit, progressive taxes, and a high minimum wage - all parts ofa general government effort to broadly distribute the gains from growth. More recent years have been characterized by reversals in all these dimensions in an institutional pattern known as the Washington Consensus. Other explanations for income disparities including skill-biased technical change and international trade are seen as factors operating within this broader institutional story. Key words: Income inequality. Institutions, Treaty ofDetroit, Washington Consensus JEL Codes: J31,J53,N32
