In this paper, we argue for a regulatory framework under which a bank’s required level of equity capital depends on the equity capital of its peers. Such bankingon- the-average rules are transparent and could also be combined with the current regulatory framework. In addition, we argue that...

Evidence suggests that banks tend to lend a lot during booms, and very little during recessions. We propose a simple explanation for this phenomenon. We show that, instead of dampening productivity shocks, the banking sector tends to exacerbate them, leading to excessive fluctuations of credit,...

We examine the impact of so-called "Crisis Contracts" on bank managers' risktaking incentives and on the probability of banking crises. Under a Crisis Contract, managers are required to contribute a pre-specified share of their past earnings to finance public rescue funds when a crisis occurs....

We consider a stochastic volatility model of the mean-reverting type to describe the evolution of a firm’s values instead of the classical approach by Merton with geometric Brownian motions. We develop an analytical expression for the default probability. Our simulation results indicate that...

We study how bankers can elicit lower capital requirements via lobbying: Bankers pledge to politicians a lobbying rate as a fraction of bank revenues, thus relating politicians' welfare to the size of banks. This induces politicians to lower capital requirements, which causes high leverage...

Bank leverage constraints can emerge from regulatory capital requirements as well as from central bank collateral requirements in reserve lending facilities. While these two channels are usually examined separately, we are able to compare them with the help of a bank money creation model in...

We provide a rationale for bank money creation in our current monetary system by investigating its merits over a system with banks as intermediaries of loanable funds. The latter system could result when CBDCs are introduced. In the loanable funds system, households limit banks' leverage ratios...

We study the political economy of bank capital regulation from a positive and normative perspective. In a general equilibrium setting, capital requirements and lobbying contributions are determined as the outcome of bargaining between banks and politicians. We show that bankers and politicians...
