Policies on financially distressed municipalities differ across US states, with some allowing unconditional access to Chapter 9 bankruptcy (Chapter 9 states) and others having proactive policies to assist distressed municipalities (Proactive states). These differences significantly affect borrowing costs. In Chapter 9 states, local municipal bond yields are higher, more cyclical, and more sensitive to default events than Proactive states. Default events have a contagion effect in Chapter 9 states, but not Proactive states. Lower local borrowing costs in Proactive states come at the expense of the state via higher intergovernmental revenue transfers in times of weak economic conditions.
