This paper studies the effects of government guarantees on the interconnection between banking and sovereign debt crises in a framework where both the banks and the government are fragile and the credibility and feasibility of the guarantees are determined endogenously. The analysis delivers...

This paper studies the interaction of government debt and financial markets. This interaction, termed a "diabolic loop", is driven by government choice to bail out banks and the resulting incentives for banks to hold government debt rather than self-insure through equity buffers. We highlight...

I propose a dynamic general equilibrium model in which strategic interactions between banks and depositors may lead to endogenous bank fragility and slow recovery from crises. When banks' investment decisions are not contractible, depositors form expectations about bank risk-taking and demand a...

This paper illustrates that systemically important banks reduce a range of activities at year- end, leading to lower additional capital requirements in the form of G-SIB buffers. The effects are stronger for banks with higher incentives to reduce the indicators, and for banks with balance sheet...

We present a quantitative model of deposit insurance. We characterize the policymaker's optimal choices of coverage for depositors and premiums raised from banks. Premiums contribute to a deposit insurance fund that lowers taxpayers' resolution cost of bank failures. We find that riskadjusted...

This paper examines common regulation as cause of interbank contagion. Studies based on the correlation of bank assets and the extent of interbank lending may underestimate the likelihood of contagion because they do not incorporate the fact that banks have a common regulator. In our model, the...

We develop a structural model for valuing bank balance sheet components such as the equity and debt value, the value for the government when the bank is operated by private shareholders including the present value of a possible future bailout, the bailout value incurred by the government...

This paper studies optimal financial policy in a world where the financial sector can become excessively optimistic. I decompose the welfare effects of bank capital regulation to demonstrate the effects of exuberance and its interaction with incentive problems in banking. The optimal policy...
