Consumption Inequality over the Last Half Century: Some Evidence Using the New PSID Consumption Measure
利用1999-2011年PSID新消费数据，通过插补法构建1967-2010年消费不平等时间序列，发现1970年代消费不平等稳定，1980年后显著上升，大衰退期间有所下降。
This paper contributes to the debate regarding trends in consumption inequality in the United States. We present a new measure of consumption inequality based on the redesigned 1999-2011 PSID. We impute consumption to the families observed before 1999 using the more comprehensive consumption data available from 1999 onward. One advantage of this procedure is in sample verification of the quality of the imputation procedure; another is that it yields a long time series (1967-2010). Consumption inequality was stable in the 1970s, as was income inequality. It increased significantly after 1980. The Great Recession was associated with a decline in consumption inequality.
