We develop a general equilibrium model of banks' capital structure, featuring heterogeneous portfolio risk and an imperfectly elastic supply of bank equity stemming from financial market segmentation. In our model, equity is costly and serves as a buffer against insolvency. Banks are ex-ante...

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...

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‘...

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...

This paper proposes a new regulatory approach that implements capital requirements contingent on executive incentive schemes. We argue that excessive risk-taking in the financial sector originates from the shareholder moral hazard created by government guarantees rather than from corporate...

The paper analyzes the interaction between an endogenous capital structure and investment decision, and the incentive scheme of bank executives. We show that the implementation of capital requirements, which are contingent on compensation schemes, drive a wedge between the interests of the...

This paper proposes a new regulatory approach that implements capital requirements contingent on managerial compensation. We argue that excessive risk taking in the financial sector originates from the shareholder moral hazard created by government guarantees rather than from corporate...

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...

This paper examines how banks' asset risk is affected by the level (i.e. group or business unit) at which regulatory requirements are applied. We develop a theoretical model and calibrate it to UK banks. Our main finding is that the impact differs depending on which regulatory constraint is...

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...
