This paper provides an explanation for the observation that banks hold on average a capital ratio in excess of regulatory requirements. We use a functional approach to banking based on Diamond and Rajan (2001) to demonstrate that banks can use capital ratios as a strategic tool for renegotiating...

This paper compares bank regulation and supervision in Japan and Germany. We consider these countries because they both have bank-dominated financial systems and their banking systems are often lumped together as one model, yet, bank stability differs significantly. We show that Japan and...

Measured by the size of their respective currency areas, the Bank of Japan and Eurosystem both belong to the most important central banks in the world. Though they have many institutional features in common and conduct monetary policy almost in similar ways, there are still important...
