We investigate optimal capital requirements in a model in which banks decide on their investment in credit scoring systems. Our main result is that regulators should encourage sophisticated banks to keep their asset portfolios safe, while assets with high systematic risk should be concentrated...

Firms will exert too little care due to a limited liability effect if damages are likely to exceed their equity. This is particularly important for environmental and product liability and motivates the current discussion about mandatory insurance and extending liability to creditors. We model...

In this paper, we analyze the German Capital Markets Model Case Law (KapMuG) enacted to reduce transaction costs in securities mass litigation. The KapMuG is often seen as a European role model trying to enhance investor rights without running the risk of frivolous claims known from the US class...
