How large should a team be? We develop a basic group work model with endogenous team size. In teams that are too small, complementarities cannot develop properly, whereas in teams that are too large, the free-rider problem becomes overwhelming. If team members are overconfident, effort levels...

Money markets have two functions, the allocation of liquidity and the processing of information. We develop a model that allows us to evaluate the efficiency of different money market derivatives regarding these two objectives. We assume that due to its size, a large bank receives a more precise...

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...

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...

Should the European Union grant state aid through an institution like the European Investment bank? This paper evaluates the efficiency of different measures for granting state aid. We use a theoretical model with firms that differ in their creditworthiness and compare different types of...

Lecture on the first SFB/TR 15 meeting, Gummersbach, July, 18 - 20, 2004: The 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...

We analyze the relationship between bank size and risk-taking under the New Basel Capital Accord. Using a model with imperfect competition and moral hazard, we show that the introduction of an internal ratings based (IRB) approach improves upon flat capital requirements if the approach is...

This paper yields a rationale for why subsidized public banks may be desirable from a regional perspective 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...

This paper provides a comprehensive theoretical and empirical analysis of “creditor rights” and “information sharing” throughout over 1.8 million private firms in Europe. We show that many of the outcomes associated with greater levels of creditor rights can be obtained with higher...
