This chapter is the third of a series on the concept and conceptualization of the corporation and the role that core actors play in it. It discusses the power and the limitations that can be observed in the player that, in mainstream doctrinal and economic conceptualization, is seen as the ultimate risk and decision taker. It deals with the power and the limitations that apply to the shareholder in their various decisions, most notably in the decision to invest or disinvest and decisions in the general meetings. While the texts discussed both refer directly to corporations as organizations, one of them decidedly takes a more general view and equally includes and refers to other types of organizations, also of the political sphere – types to which the second text could at least be related.
