Witzany, Jiří; Rychnovský, Michal; Charamza, Pavel - In: European financial and accounting journal : EFAJ 7 (2012) 1, pp. 6-27

The paper proposes an application of the survival time analysis methodology to estimations of the Loss Given Default (LGD) parameter. The main advantage of the survival analysis approach compared to classical regression methods is that it allows exploiting partial recovery data. The model is...

Unexpected recovery risk and LGD discount rate determination

Witzany, Jiří - In: European financial and accounting journal : EFAJ 4 (2009) 1, pp. 61-84

The Basle II parameter called Loss Given Default (LGD) aims to estimate the expected losses on not yet defaulted accounts in the case of default. Banks firstly need to collect historical recovery data, discount the recovery income and cost cash flow to the time of default, and calculate...

Exposure at default modeling with default intensities

Witzany, Jiří - In: European financial and accounting journal : EFAJ 6 (2011) 4, pp. 20-48

The paper provides an overview of the Exposure at Default (EAD) definition, requirements, and estimation methods as set by the Basel II regulation. A new methodology connected to the intensity of default modeling is proposed. The numerical examples show that various estimation techniques may...

A capital adequacy buffer model

Allen, David E.; McAleer, Michael; Powell, Robert; … - 2013

In this paper, we develop a new capital adequacy buffer model (CABM) which is sensitive to dynamic economic circumstances. The model, which measures additional bank capital required to compensate for fluctuating credit risk, is a novel combination of the Merton structural model which measures...

Risk sensitivity of banks, interbank markets and the effects of liquidity regulation : conference paper

Pausch, Thilo - 2013 - First draft

The industrial organization approach to banking is extended to analyze the effects of interbank market activity and regulatory liquidity requirements on bank behavior. A multi-stage decision situation allows for considering the interaction between credit risk and liquidity risk of banks. This...

Back to the roots of internal credit risk models : why do banks' risk-weighted asset levels converge over time?

Böhnke, Victoria; Ongena, Steven; Paraschiv, Florentina; … - 2022

The internal ratings-based (IRB) approach maps banks’ risk profiles more adequately than the standardized approach. After switching to IRB, banks’ risk-weighted asset (RWA) densities are thus expected to diverge, especially across countries with different supervisory strictness and risk...
