We investigate the relationship between bank complexity and bank risk-taking using German banking data over the period 2005-2017. We find that more complex banking organizations tend to take on more risk, but that this complexity-risk nexus decreases over time. We study how regulatory...

In Europe, the financial stability mandate generally rests at the national level. But there is an important exception. Since the establishment of the Banking Union in 2014, the European Central Bank (ECB) can impose stricter regulations than the national regulator. The precondition is that the...

This paper investigates determinants of banks' structural exposure to interest rate risk in their banking book. Using bank-level data for German banks, we find evidence that a bank's exposure to interest rate risk depends on its presumed optimization horizon. The longer the presumed optimization...

We estimate a dynamic structural banking model to examine the interaction between risk-weighted capital adequacy and unweighted leverage requirements, their differential impact on bank lending, and equity buffer accumulation in excess of regulatory minima. Tighter risk-weighted capital...

We analyze the impact of the announcement of the banking union on stock market returns of euro area banks against the backdrop of three commonly held views of the banking union. We document positive individual abnormal returns for most banks. Abnormal returns are large and positive on average,...
