Intergenerational Redistribution in the Great Recession
构建随机世代交叠一般均衡模型，量化严重衰退的福利成本在不同年龄群体间的分布，发现资产价格相对工资大幅下跌时，年轻群体受益而老年群体受损。
In this paper we construct a stochastic overlapping-generations general equilibrium model in which households are subject to aggregate shocks that affect both wages and asset prices. We use a calibrated version of the model to quantify how the welfare costs of severe recessions are distributed across different household age groups. The model predicts that younger cohorts fare better than older cohorts when the equilibrium decline in asset prices is large relative to the decline in wages, as observed in the data. Asset price declines hurt the old, who rely on asset sales to finance consumption, but benefit the young, who purchase assets at depressed prices. In our preferred calibration, asset prices decline more than twice as much as wages, consistent with the experience of the US economy in the Great Recession. A model recession is approximately welfare-neutral for households in the 20?29 age group, but translates into a large welfare loss of around 10% of lifetime consumption for households aged 70 and over.
