Flooded Through the Back Door: Firm-level Effects of Banks‘ Lending Shifts

Oliver Rehbein

in: IWH-Diskussionspapiere , Nr. 4, 2018


I show that natural disasters transmit to firms in non-disaster areas via their banks. This spillover of non-financial shocks through the banking system is stronger for banks with less regulatory capital. Firms connected to a disaster-exposed bank with below median capital reduce their employment by 11% and their fixed assets by 20% compared to firms in the same region without such a bank during the 2013 flooding in Germany. Relationship banking and higher firm capital also mitigate the effects of such negative cross-regional spillovers.

Badly Hurt? Natural Disasters and Direct Firm Effects

Felix Noth Oliver Rehbein

in: IWH-Diskussionspapiere , Nr. 25, 2017


We investigate firm outcomes after a major flood in Germany in 2013. We robustly find that firms located in the disaster regions have significantly higher turnover, lower leverage, and higher cash in the period after 2013. We provide evidence that the effects stem from firms that already experienced a similar major disaster in 2002. Overall, our results document a positive net effect on firm performance in the direct aftermath of a natural disaster.

Borrowers Under Water! Rare Disasters, Regional Banks, and Recovery Lending

Michael Koetter Felix Noth Oliver Rehbein

in: IWH-Diskussionspapiere , Nr. 31, 2016


We test if and how banks adjust their lending in response to disaster risk in the form of a natural catastrophe striking its customers: the 2013 Elbe flooding. The flood affected firms in East and South Germany, and we identify shocked banks based on bank-firm relationships gathered for more than a million firms. Banks with relationships to flooded firms lend 13-23% more than banks without such customers compared to the preflooding period. This lending hike is associated with higher profitability and reduced risk. Our results suggest that local banks are an effective mechanism to mitigate rare disaster shocks faced especially by small and medium firms.
