Bankruptcy and the Collateral Channel

Do bankrupt firms impose negative externalities on their nonbankrupt competitors? We propose and analyze a collateral channel in which a firm's bankruptcy reduces the collateral value of other industry participants, thereby increasing their cost of debt financing. We identify the collateral channel using novel data of secured debt tranches issued by U.S. airlines that include detailed descriptions of the underlying collateral pools. Our estimates suggest that industry bankruptcies have a sizeable impact on the cost of debt financing of other industry participants. We discuss how the collateral channel may lead to contagion effects that amplify the business cycle during industry downturns.
