In this paper, we study the economic benets from using credit scoring models. We contribute to the literature by relating the discriminatory power of a credit scoring model to the optimal credit decision. Given the Receiver Operating Characteristic (ROC) curve of the credit scoring model, we...

In the work of the Basel Committee there has been a tradition ofdistinguishing market from credit risk and to treat both categories independentlyin the calculation of risk capital. In practice positionsin a portfolio depend simultaneously on both market and credit riskfactors. In this case, an...

We study the extremal dependence of market and liquidity risk, the former beingmeasured through the market return and the latter being measured throughthe relative bid-ask spread. We apply a non-parametrical approach to measurebivariate exceedance probabilities and the respective dependence...

The present paper shows how the parameters of three popular portfolio credit risk models can be empiricallyestimated by banks using a Maximum Likelihood framework. We apply the method to a database of Germanfirms provided by Deutsche Bundesbank and analyze the inclusion of macroeconomic and...
