We estimate the structural parameters of a quantitative banking model featuring maturity transformation and endogenous failures in the presence of undiversifiable background risk and regulatory constraints. Pervasive balance sheet cross-sectional heterogeneity can be rationalized with...

We address the following questions concerning bank capital: why are banks so highly levered, what are the consequences of this leverage for the economy as a whole, and how can robust capital regulation be designed to restrict bank leverage to levels that do not generate excessive systemic risk?...

Banks’ behaviour can be influenced by both monetary policy and regulatory capital requirements. This paper explores the interaction between these two policy tools in promoting better lending decisions by banks. We develop and calibrate a model of bank lending to examine what an optimal...

Today’s regulatory rules, especially the easily-manipulated measures of regulatory capital, have led to costly bank failures. We design a robust regulatory system such that (i) bank losses are credibly borne by the private sector (ii) systemically important institutions cannot collapse...

We propose a new form of hybrid capital for banks, Equity Recourse Notes (ERNs), which ameliorate booms and busts by creating counter-cyclical incentives for banks to raise capital, and so encourage bank lending in bad times. They avoid the flaws of existing contingent convertible bonds...

We present a simple model of an economy with heterogeneous banks that may be funded with uninsured deposits and equity capital. Capital serves to ameliorate a moral hazard problem in the choice of risk. There is a fixed aggregate supply of bank capital, so the cost of capital is endogenous. A...

We examine the validity of a macroeconomic version of the Modigliani-Miller theorem. For this purpose, we develop a general equilibrium model with two production sectors, risk-averse households and financial intermediation by banks. Banks are funded by deposits and (outside) equity and monitor...

We analyze banks' systemic risk taking in a simple dynamic general equilibrium model. Banks collect funds from savers and make loans to firms. Banks are owned by risk-neutral bankers who provide the equity needed to comply with capital requirements. Bankers decide their (unobservable) exposure...

This paper studies the strategic interaction between a bank whose deposits are randomly withdrawn, and a lender of last resort (LLR) that bases its decision on supervisory information on the quality of the bank’s assets. The bank is subject to a capital requirement and chooses the liquidity...

We analyse the implications for the pricing of bank loans of the reform of capital regulation known as Basel II. We consider a perfectly competitive market for business loans where, as in the model underlying the internal ratings based (IRB) approach of Basel II, a single risk factor explains...
