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.

We analyze the effects of capital regulation on bank stability in a model where banks compete for loans and deposits, and where they face both a portfolio and an optimal contracting problem. In our setup, stricter capital regulation increases the risk of individual loans and may also increase a...

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 banking sector. Our main result is that the bail-out policy unambiguously...

This paper discusses the relationship between bank size and risk-taking under Pillar I of the New Basel Capital Accord. Using a model with imperfect competition and moral hazard, we find that small banks (and hence small borrowers) may profit from the introduction of an internal ratings based...

This paper empirically investigates the effect of government bail-out policies on banks outside the safety net. We construct a measure of bail-out perceptions by using rating information. From there, we construct the market shares of insured competitor banks for any given bank, and analyze the...

This paper analyzes how a bank shareholder optimally designs the compensation scheme of a bank manager if there are agency problems between the shareholder and the manager, and how this design changes in reaction to anticipated bail-outs. If there is a problem of excessive risk-taking, bail-out...
