Lecture on the first SFB/TR 15 meeting, Gummersbach, July, 18 - 20, 2004The explicit or implicit protection of banks through government bail-out policies is a universal phenomenon. We analyze the competitive effects of such policies in two models with different degrees of transparency in the...

This paper yields a rationale for why subsidized public banks may increase regional welfare in a financially integrated economy. We present a model with credit rationing and heterogeneous regions in which public banks prevent a capital drain from poorer to richer regions by subsidizing local...

This paper shows that bonus contracts may arise endogenously as a response to agency problems within banks, and analyzes how compensation schemes change in reaction to anticipated bail-outs. If there is a risk-shifting problem, bail-out expectations lead to steeper bonus schemes and even more...

This paper discusses the effects of small banks on economic growth. We first theoretically show that small banks operating at a regional level can spur local economic growth. As compared with big interregional banks, small regional banks are more effective in promoting local economic growth,...

We construct a model of the banking firm with inside and outside equity and use it to study bank behavior and regulatory policy during crises. In our model, a bank can increase the risk of its asset portfolio (“risk shift”), convert bank assets to the personal benefit of the bank manager...

For many private firms, relationship lending is the only viable form of outside financing. Relationship lending typically relies on intertemporal loan pricing: losses from early years are recovered by information rents in later years, which stem from the lender's private information regarding...

The severity and depth of the recent financial crisis hit many by surprise. Despite warning signs, the financial system seems to have been unable to aggregate existing information. As the events of Fall 2008 showed, many investors were caught off guard by the large number of banks collapsing...

We analyze capital requirements if banks compete for loans and deposits. Banks and firms are subject to a risk-shifting problem. The ambiguous effect of competition on banks’ risk-taking translates into an ambiguous effect of capital requirements on financial stability.

In the recent financial crisis, risk management tools have been proven inadequate. Model risk, a key component of bank risk, has shown its negative impact. It seems that risk models did not cover the included risks comprehensively and were not kept up-to-date by banks, and also rating agencies....

One explanation for the poor performance of regulation in the recent financial crisis is that regulators had been captured by the financial sector. We present a micro-founded model with rational agents in which banks may capture regulators due to their high degree of sophistication. Banks can...
