Inequality in Russia over time and over the life cycle
利用1994-2018年俄罗斯面板数据,发现消费和收入不平等长期下降,但生命周期内不平等曲线平坦,通过校准模型解释了资产保险作用大的谜题。
Abstract Using Russian longitudinal data for 1994–2018, we document a secular decline in consumption and income inequality. Although within‐cohort inequality is also declining, the life‐cycle inequality profiles of income and consumption are surprisingly flat. A calibrated life‐cycle model with incomplete markets, high initial variance of the persistent income component, and moderately persistent income shocks is consistent with nearly flat life‐cycle inequality profiles and the puzzlingly large insurance role of assets found in the Russian data. This is in contrast to the standard calibrations that fail to match the life‐cycle inequality profiles and the panel‐data evidence on consumption insurance.
