  We construct two examples of shareholder networks in which shareholders are
connected if they have shares in the same company. We do this for the
shareholders in Turkish companies and we compare this against the network
formed from the shareholdings in Dutch companies. We analyse the properties of
these two networks in terms of the different types of shareholder. We create a
suitable randomised version of these networks to enable us to find significant
features in our networks. For that we find the roles played by different types
of shareholder in these networks, and also show how these roles differ in the
two countries we study.
