Morton Paglin recently proposed a new summary statistic~ the "Paglin-Gini," which he uses to measure an.d analyze the level and trend of income inequality in the United States. In contrast with the standard Lorenz-Gini, which counts all income differences among living units in measuring inequality, the Paglin-Gini defines meaningful inequality to include only the differences in family incomes that are unrelated to the observed age-income profile. Paglin's measure indicates substantially less inequality in the United States than does the Lorenz-Gini. According to Paglin's measure, moreover, inequality has fallen considerably since World War II; other measures indicate very little change in inequality over this period. In this comment we describe Paglin's procedure and ch~llenge his measure on both computational and normative grounds. Paglin's interpretation of policy-relevant inequality and the implications of the Paglin-Gini for analyzing the equity of the transfer system are questioned. We conclude that the Paglin-Gini provides a misleading interpretation of .the level and trend of income inequality in the postwar period.
