Speaker: Sebastian Gryglewicz, Erasmus University Rotterdam

About the seminar

We develop a theory of large shareholder ownership and firm policies, in which a blockholder dynamically adjusts their ownership stake over time, thereby shaping their level of engagement and the firm’s decisions. We analytically characterise the dynamic trading strategy of the blockholder and the firm’s financing, investment and compensation policies, assuming no commitment from the blockholder. In equilibrium, the large shareholder may increase or decrease their stake over time, potentially leading to exit or a full takeover. While limiting blockholder control may benefit dispersed shareholders in the short term, it ultimately leads to reduced ownership and engagement by the blockholder, lowering firm value over the long run.
