Outright bank failures without prior indication of financial instability are very rare. Supervisory authorities monitor banks constantly. Thus, they usually obtain early warning signals that precede ultimate failure and, in fact, banks can be regarded as troubled to varying degrees before...

We study the risk of holding credit default swaps (CDS) in the trading book. In particular, we compare the Value at Risk (VaR) of a CDS position to the VaR for investing in the respective firm's equity. Our sample consists of CDS – stock price pairs for 86 actively traded firms over the period...

The credit value-at-risk model underpinning the Basel II Internal Ratings-Based approach assumes that idiosyncratic risk has been diversified away fully in the portfolio, so that economic capital depends only on systematic risk contributions. We develop a simple methodology for approximating the...

For their short-term payment obligations, savings banks hold substantially more liquid assets than the liquidity regulation requires. This paper investigates whether sight deposits, an important funding source for savings banks, help in explaining liquid asset holdings in excess of regulatory...

This paper investigates the returns and flows of German money market funds before and during the liquidity crisis of 2007/2008. The main findings of this paper are: In liquid times money market funds enhanced their returns by investing in less liquid papers. By doing so they outperformed other...

The question of whether or not mergers and acquisitions have helped to enhance banks' efficiency and profitability has not yet been conclusively resolved in the literature. We argue that this is partly due to the severe methodological problems involved. In this study, we analyze the effect of...

This paper shows that the substantial disparity in German bank lending towards industrial (IC) and non-industrial (Non-IC) countries is largely explained by differences in countries' endowments and only to a minor extent by German banks' different treatment of these country groups. This is...

Two shrinkage estimators for the global minimum variance portfolio that dominate the traditional estimator with respect to the out-of-sample variance of the portfolio return are derived. The presented results hold for any number of observations n = d 2 and number of assets d = 4. The...

Recent empirical studies criticize the sluggish financial integration in the euro area and find that only interbank money markets are fully integrated so far. This paper studies the optimal regional and/or sectoral integration of financial systems given that integration is restricted to the...

Assessments of investors' risk appetite/aversion stance via indicators often yields results which seem unsatisfactory (see e.g. Illing and Aaron (2005)). Understanding how such indicators work therefore seems essential for further improvements. The present paper seeks to contribute to this...
