Consumption Inequality
讨论消费不平等在经济福祉测量中的重要性，比较消费与收入指标的优劣，评估消费不平等是否如收入不平等那样增长，并探索支出构成、休闲时间和代际消费流动性的新证据。
In this essay, we discuss the importance of consumption inequality in the debate concerning the measurement of disparities in economic well-being. We summarize the advantages and disadvantages of using consumption as opposed to income for measuring trends in economic well-being. We critically evaluate the available evidence on these trends, and in particular discuss how the literature has evolved in its assessment of whether consumption inequality has grown as much as or less than income inequality. We provide some novel evidence on three relatively unexplored themes: inequality in different spending components, inequality in leisure time, and intergenerational consumption mobility.
