Abstract

We develop a novel framework featuring loss amplification through firm-bank linkages. We use it to study optimal intervention in a lockdown situation that creates cash shortfalls for firms, which must resort to bank lending. Firms’ increased debt reduces their output due to moral hazard. Banks need safe collateral to raise funds. Without intervention, aggregate risk constrains bank lending, amplifying output losses. Optimal government support provides sufficient aggregate risk insurance, and is implemented through transfers to firms and fairly-priced guarantees on banks’ debt. When aggregate risk is not too large, such guarantees can be financed through a procyclical taxation of firms’ profits.
