During the last decades a consensus has emerged that it is impossible to disentangle liquidity shocks from solvency shocks. As a consequence the classical lender of last resort rules, as defined by Thornton and Bagehot, based on lending to solvent illiquid institutions appear ill-suited to this...

We develop a simple model of banking regulation with two policy instruments: minimum capital requirements and supervision of domestic banks. The regulator faces a trade-off: high capital requirements cause a drop in the banks' profitability, while strict supervision reduces the scope of...

Trade finance, particularly in the form of short-term letters of credit has received favourable capital treatment new Basel III rules. However, concerns have been expressed over the potential negative “unintended consequences” of the newly created leverage ratio for trade. This paper offers...

We show that the impact of government bailouts (liquidity injections) on a representative bank's risk taking depends on the level of systematic risk of its loans portfolio. In a model where bank's output follows a geometric Brownian motion and the government guarantees bank's liabilities, we...

This paper studies banks' liquidity provision in the Lagos and Wright model of monetary exchanges. With aggregate uncertainty we show that banks sometimes exhaust their cash reserves and fail to satisfy their depositors' need of consumption smoothing. The banking panics can be eliminated by the...

We develop a stylized DSGE model in which banks face capital regulation and their loan portfolios are subject to non-diversifiable losses due to aggregate shocks. The framework is used to explore the importance of the interaction between macroeconomic conditions, credit default and bank...

In this paper we model the volatility of the spread between the overnight interest rate and the central bank policy rate (the policy spread) for the euro area and the UK during the two main phases of the financial crisis that began in late 2007. During the crisis, the policy spread exhibited...

Tax provisions favoring corporate debt over equity finance (“debt bias”) are widely recognized as a risk to financial stability. This paper explores whether and how thin-capitalization rules, which restrict interest deductibility beyond a certain amount, affect corporate debt ratios and...

This paper studies loan activity in a context where banks must follow Basel Accord-type rules and acquire financing from households. Loan activity typically decreases when entrepreneurs' investment returns decline, and we study which type of policy could revigorate an economy in a trough. We...

We present a simple neoclassical model to explore how an aggregate bank-capital requirement can be used as a macroeconomic policy tool and how this additional tool interacts with monetary policy. Aggregate bank-capital requirements should be adjusted when the economy is hit by cost-push shocks...
