We examine, conditional on structural shocks, the macroeconomic performance of different countercyclical capital buffer (CCyB) rules in small open economy estimated medium scale DSGE. We find that rules based on the credit gap create a trade-off between the stabilization of fluctuations...

We study banks' optimal equity buffer in general equilibrium and their response to under-capitalization. Making progress towards a "pecking order theory" for private recapitalizations, our benchmark model identifies equity issuance as individually and socially optimal, compared to deleveraging,...

This paper provides an explanation for the observation that banks hold on average a capital ratio in excess of regulatory requirements. We use a functional approach to banking based on Diamond and Rajan (2001) to demonstrate that banks can use capital ratios as a strategic tool for renegotiating...

The aim of this paper is to assess how German savings banks adjust capital and risk under capital regulation. We estimate a modified version of the model developed by Shrieves and Dahl (1992). In comparison to former research, we impose fewer restrictions with regard to the impact of regulation...

The new Basel Capital Adequacy Accord (Basel III) is an agreement among countries' central banks and bank supervisory authorities on the amount of capital banks must hold as a cushion against losses and insolvency. Basel III is of concern to Congress mainly because it could put U.S. financial...

Regulators and managers in the banking sector prioritize the banking system's stability and safety to limit risks, shocks, and potential losses. This study reveals why a bank is more or less stable via bank capital, liquidity creation, and asset diversification. We form a structural model in...

This research aims to investigate the influence of bank capital, risk-based capital and bank capital buffers on the behaviour of bank risk-taking by applying GMM on the data of US commercial banks ranges from 2002 to 2018. The findings show that bank capital has a positive influence on total...

Fifteen years after the introduction of the Basel II Accord, which thoroughly revised the capital framework for banks, internal models are a full part of the supervisory toolkit and the risk management framework of financial institutions. The debate around models has gone through different...

In many standard derivation and presentations of risk measures like the Value-at-Risk or the Expected Shortfall, it is assumed that all the model's parameters are known. In practice, however, the parameters must be estimated and this introduces an additional source of uncertainty that is usually...

The level of capital requirement generated by the IRB approach depends crucially on the asset correlation, a parameter that enters the regulatory risk weight formula and is determined by the Regulators. Several studies have estimated the asset correlations and found that the empirical values are...
