We analyze the dynamics of banks' regulatory capital ratios. Using monthly data of regulatory capital ratios for a subset of large German banks, we estimate the target level and the adjustment speed of the capital ratio for each bank separately. We find evidence that, first, there exists a...

We derive approximate formulae for the credit value-at-risk and the economic capital of a large credit portfolio. The representation allows to change the risk horizon quickly and avoids simulation or numerical procedures. The Poisson mixture model is equivalent to CreditRisk and uses the same...

Banks typically determine their capital levels by separately analysing credit and interest rate risk, but the interaction between the two is significant and potentially complex. We develop an integrated economic capital model for a banking book where all exposures are held to maturity. Our...

Vorliegende Studie analysiert die Determinanten der Eigenkapitalrendite deutscher Sparkassen. Die Untersuchung erfolgt auf Basis eines Paneldatensatzes, der die Bilanzdaten sowie regulatorischen Kenngrößen aller Sparkassen in Deutschland zwischen 1999 und 2007 beinhaltet. Die Ergebnisse der...
