"The Evolution of Income, Consumption, and Leisure Inequality in the United States, 1980–2010," in Christopher D. Carroll, Thomas F. Crossley, and John Sabelhaus, editors, "Improving the Measurement of Consumer Expenditures" University of Chicago Press (2015) AB - Recent research has documented that income inequality in the United States has increased dramatically over the prior three decades. There has been less of a consensus, however, on whether the increase in income inequality was matched by an equally large increase in consumption inequality. Most researchers have studied this question using data from the Consumer Expenditure Survey (CE) and some studies have suggested that the increase in consumption inequality has been modest. Unfortunately ,there is now mounting evidence that the CE is plagued by serious non-classical measurement error, which hinders the extent to which definitive conclusions can be made about the extent to which consumption inequality has evolved over the last three decades. In this paper, we use a variety of different techniques to overcome the measurement error problems with the CE. First, we use data from the diary component of the CE, focusing on categories where measurement error has been found to be less of an issue. Second, we explore inequality measures within the CE using the value of vehicles owned, a consumption component that is considered to be measured well. Third, we try to account directly for the non-classical measurement error of the CE by comparing the spending on luxuries (entertainment) relative to necessities (food). This is similar to the recent approach taken by Browning and Crossley (2009) and Aguiar and Bils (2011). Finally, we use expenditure data from the Panel Study of Income Dynamics to explore the dynamics of alternative measures of consumption inequality. All of our different methods yield similar results. We find that consumption inequality within the U.S. between 1980 and 2010 has increased by nearly the same amount as income inequality. ER -
