We develop a dynamic structural model of bank behaviour that provides a microeconomic foundation for bank capital and liquidity structures and analyses the effects of changes in regulatory capital and liquidity requirements as well as their interaction. Our findings suggest that adjustments in...

We develop a dynamic model of banking to assess the effects of liquidity and leverage requirements on banks' insolvency risk. In this model, banks face taxation, flotation costs of securities, and default costs and maximize shareholder value by making their financing, liquid asset holdings, and...

We take issue with claims that the funding mix of banks, which makes them fragile and crisis-prone, is efficient because it reflects special liquidity benefits of bank debt. Even aside from neglecting the systemic damage to the economy that banks' distress and default cause, such claims are...

We examine the optimal size and composition of banks' total loss absorbing capacity (TLAC). Optimal size is driven by the trade-off between providing liquidity services through deposits and minimizing deadweight default costs. Optimal composition (equity vs. bail-in debt) is driven by the...

Bank regulators interfere with the efficient allocation of resources for the sake of financial stability. Based on this trade-off, I compare how different capital requirements affect default probabilities and the allocation of market shares across heterogeneous banks. In the model, banks‘...

At least the current Financial Crisis shows that the global banking sector is not robust against tail risks. In particular, the sufficiency of solely focussing on risk-sensitive capital requirements in the BASEL II framework to stabilize the banking system has been doubted. A possible solution...

Hub-and-spoke regulation, where a central regulator with legal power over firms delegates monitoring to local supervisors, can improve information collection, but can also lead to agency problems and capture. We document that following the closure of a US bank regulator's field offices, the...

This paper investigates bank portfolio composition under Basel II where the amount of required capital is determined by bank's own risk assessment. We particularly show that in presence of asymmetric information between the bank and the supervisor, it has incentives to understate its risk taking...

Basel III has introduced a non-risk-weighted leverage ratio requirement (LRR) which complements the internal ratings based (IRB) capital requirements. It provides a backstop against model risk which arises if some loans get incorrectly rated and become toxic. We study the effects of the LRR on...
