In this global world, many firms present a complex shareholding structure with<p>indirect participation, such that it may become difficult to assess a firm’s controllers.<p>Furthermore, if there are numerous dominant shareholders, the control can be shared between<p>them. Determining who has the most influence is often a difficult task. To measure this<p>influence, game theory allows the modeling of voting games and the computing of the<p>Banzhaf index. This thesis develops models to measure the Banzhaf indices in any ownership structure (pyramidal ownership structures and cross-ownership structures). The models are then applied to real cases studies such Colruyt, Elia, Lafarge and Allianz. / Doctorat en Sciences économiques et de gestion / info:eu-repo/semantics/nonPublished
