Flood, farms and credit: The role of branch banking in the era of climate change
利用2019年4月伊朗突发洪水作为自然实验，发现当地分行在政府援助前通过增加贷款弥补时间缺口，与分行关系更强的农民（尤其是年轻人和女性）更易获得恢复贷款，表明关系型分行银行在灾难中对农业社会仍很重要。
Using Iran’s unexpected flood in April 2019 as a natural experiment, we show that local branches bridge the time gap between the disaster and governmental aids by immediately increasing their lending for two months following the flood. Analyzing proprietary information on more than 53,000 farmers, we find that farmers with a stronger relationship with their branch - particularly younger and females - are more likely to receive a recovery loan. Our findings underscore that despite recent technological advancements, relationship-based branch banking is still important for agrarian societies during catastrophic events.
