From Earnings Inequality to Consumption Inequality
研究收入不平等如何传导至家庭消费不平等，通过分析英国同代人群收入和消费的方差与协方差随时间的变化，识别永久性和暂时性冲击，并扩展至夫妻双方收入。
This paper studies the paths from inequality in earnings to inequality in household consumption. We show that careful study of the evolution of the variances and covariances of earnings and consumption within cohorts across time can identify permanent and transitory shocks. We present an application to the evolution of inequality in the United Kingdom. We extend previous results to recognise separate earnings of partners in couples.
