灾后恢复贷款的需求曲线

A Demand Curve for Disaster Recovery Loans
Econometrica · 2024 · Benjamin Collier、Cameron Ellis

中文摘要

我们估计并描绘了近期因自然灾害遭受住房损失的家庭的信贷需求曲线。我们的行政数据涵盖一项面向家庭的联邦灾后恢复贷款计划的一百多万名申请者。我们估计了较大利率区间内广延边际上的需求。我们的识别策略利用了24项自然实验,借助该计划所提供利率随时间变化的外生变动进行识别。在整个利率分布范围内,利率均对消费者需求产生实质性影响。平均而言,利率上升1个百分点会使贷款接受率降低26%。我们发现申请者的信用质量对需求具有较大影响,并发现了以月供金额为目标进行选择的证据。利用估计的需求曲线和计划成本信息,我们发现该计划为每位借款人平均创造了2900美元的社会剩余。

Abstract

We estimate and trace a credit demand curve for households that recently experienced damage to their homes from a natural disaster. Our administrative data include over one million applicants to a federal recovery loan program for households. We estimate extensive‐margin demand over a large range of interest rates. Our identification strategy exploits 24 natural experiments, leveraging exogenous, time‐based variation in the program's offered interest rate. Interest rates meaningfully affect consumer demand throughout the distribution of rates. On average, a 1 percentage point increase in the interest rate reduces loan take‐up by 26%. We find a large impact of applicants' credit quality on demand and evidence of monthly payment targeting. Using our estimated demand curve and information on program costs, we find that the program generates an average social surplus of $2900 per borrower.
