We study supervisory interventions in cross-border banks under different institutional architectures in a model in which a bank may provide voluntary support to an impaired subsidiary using resources from a healthy subsidiary. While supranational architecture permits voluntary support, national...

We analyze the design of bailout regimes when investment is distorted by a toomany-to-fail problem. The first-best allocation equalizes benefits from more banks investing in high-return projects with endogenously higher systemic risk due to more banks failing simultaneously. A standard bailout...

We quantify the gains from regulating banks' maturity transformation in an infinite horizon model of banks which finance long-term assets with non-tradable debt. Banks choose the amount and maturity of their debt trading off investors' preference for short maturities with the risk of systemic...

We characterize the optimal banking union with endogenous participation in a two-country economy in which domestic bank failures may be contemporaneous to sovereign crises, giving rise to risk-sharing motives to mutualize the funding of bailouts. Bank bail-ins create disruption costs that are...
