家庭杠杆与经济衰退

Household Leverage and the Recession
Econometrica · 2022 · Callum Jones、Virgiliu Midrigan、Thomas Philippon

中文摘要

我们评估并部分质疑了关于大衰退的家庭杠杆观点。在数据中,家庭债务下降更多的美国各州,其就业和消费下降幅度也更大。我们研究了一个由多个地区组成的货币联盟模型,其中流动性约束塑造了就业和消费对债务变化的反应。我们使用结合州级与总体数据的贝叶斯方法估计了该模型。家庭信贷的变化解释了各州之间就业差异化升降的40%,但仅解释了2007–2010年总体就业下降的一小部分。然而,由于家庭去杠杆是逐步的,信贷冲击极大地拖慢了复苏。

Abstract

We evaluate and partially challenge the household leverage view of the Great Recession. In the data, employment and consumption declined more in U.S. states where household debt declined more. We study a model of a monetary union composed of many regions in which liquidity constraints shape the response of employment and consumption to changes in debt. We estimate the model with Bayesian methods combining state and aggregate data. Changes in household credit explain 40% of the differential rise and fall of employment across states, but a small fraction of the aggregate employment decline in 2007–2010. Nevertheless, since household deleveraging was gradual, credit shocks greatly slowed the recovery.
