We introduce a model of the banking sector that formally incorporate a buffer function of capital. Heterogeneous banks choose their portfolio risk, bank size, and capital holdings. Banks voluntarily hold equity when the buffer effect against the risk of default outweighs the cost advantages of...

We build a stylized dynamic general equilibrium model with financial frictions to analyze costs and benefits of capital requirements in the short-term and long-term. We show that since increasing capital requirements limits the aggregate loan supply, the equilibrium loan rate spread increases,...

How do banks facilitate creative destruction and shape firm turnover? We develop a dynamic general equilibrium model of bank credit reallocation with endogenous firm entry and exit that allows for both theoretical and quantitative analysis. By restructuring loans to firms with poor prospects and...

This paper presents a micro data approach to the identification of credit crunches. Using a survey among German firms which regularly queries the firms' assessment of the current willingness of banks to extend credit we estimate the probability of a restrictive credit supply policy by time...

Insufficient capital buffers of banks have been identified as one main cause for the large systemic effects of the recent financial crisis. Although higher capital is no panacea, it yet features prominently in proposals for regulatory reform. But how do increased capital requirements affect...

We explore how changes in capital-based macroprudential regulation in the euro area affect the exposure of national banking sectors to domestic government debt, thus strengthening or weakening the sovereign-bank nexus. To do so, we construct a measure of macroprudential policy based on the...

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...

This project analyzes how a principal can motivate an agent to conserve rather than exploit a depletable resource. This dynamic problem is relevant for tropical deforestation as well as for other environmental problems. It is shown that the smaller is the agent's discount factor (e.g., because...

The loans of the IMF, World Bank, and other multilateral development banks (MDBs) are excluded from debt restructuring. This is the result of their preferred creditor status. There are two justifications for the preferred creditor status of MDBs: (a) they give concessional loans, and (b) they...

We evaluate the effects of the 2020 student debt moratorium that paused payments for student loan borrowers. Using administrative credit panel data, we show that the payment pause led to a sharp drop in student loan payments and delinquencies for borrowers subject to the debt moratorium, as well...
