This paper characterizes 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 bail-outs. Raising public funds to conduct a...

The Single Market stimulates cross-border banking throughout the European Union. This paper documents the banking linkages between the 9 ‘outs' and 19 ‘ins' of the Banking Union. We find that some of the major banks, based in Sweden and Denmark, have substantial banking claims across the...

While the first two pillars of the European Banking Union have been implemented, a European deposit insurance scheme (EDIS) is still not in place. To facilitate its introduction, recent proposals argue in favor of a reinsurance scheme. In this paper, we use a regime-switching open-economy DSGE...

Recent proposals for a still missing European deposit insurance scheme (EDIS) argue in favor of a reinsurance framework. In this paper, we use a regime-switching open-economy DSGE model with bank default to assess the relative efficiency of such a scheme. We find that reinsurance by EDIS is more...

Stress-tests provide complementary information about banks’ risk exposures. Recent empirical evidence, however, has uncovered potential inaccuracies in stress-test based assessments. We investigate the regulatory implications of these inaccuracies. Without stress-tests, the regulator cannot...

This paper presents a bank capital structure model in which equity holders can increase asset risk once debt is in place. I study the effects of capital requirements and subsidized deposit insurance on the bank's privately optimal funding and operational risk level. The model predicts that there...

The explicit or implicit protection of banks through government bail-out policies is a universal phenomenon. We analyze the competitive effects of such policies in two models with different degrees of transparency in the banking sector. Our main result is that the bail-out policy unambiguously...

We study the political economy of bank capital regulation from a positive and normative perspective. In a general equilibrium setting, capital requirements and lobbying contributions are determined as the outcome of bargaining between banks and politicians. We show that bankers and politicians...

We provide a welfare comparison of the two types of banking regulation commonly used to address moral hazard problems, deposit rate ceilings and minimum capital requirements. It is well understood that interference with the price mechanism may lead to inefficiencies -- in the case of a deposit...

We exploit the establishment of a supranational supervisor in Europe (the Single Supervisory Mechanism) to learn how the organizational design of supervisory institutions impacts the enforcement of financial regulation. Banks under supranational supervision are required to increase regulatory...
