No derivative shareholder suits in Europe: A model of percentage limits and collusion

We address one of the cardinal puzzles of European corporate law: the lack of derivate share-holder suits. We explain this phenomenon on the basis of percentage limits which require share-holders to hold a minimum amount of shares in order to bring a lawsuit. We show that, under this legal regime, managers will collude with large shareholders by means of settlements or bribes that impose a negative externality on small shareholders. Contrary to conventional agency models, we find that large shareholders do not monitor the management; as a consequence, there is no free riding opportunity for small shareholders.
