Renegotiation in Debt Chains

We develop a tractable model of strategic debt renegotiation in which businesses are sequentially interconnected through their liabilities. This financing structure, which we refer to as a debt chain, gives rise to externalities as a lender’s willingness to provide concessions to his privately-informed borrower depends on how this lender’s own liabilities are expected to be renegotiated. Our analysis reveals how targeted government subsidies and debt reductions as well as incentives for early renegotiation following large economic shocks such as COVID-19 or a financial crisis can prevent default waves.
