آیا تغییرات بیرونی در مالکیت غیر منفعلانه، بر حاکمیت شرکت ها و ارزش شرکت تاثیر می گذارد؟

We investigate whether corporations and their executives react to an exogenous change in passive institutional ownership and alter their corporate governance structure. We find that exogenous increases in passive ownership lead to increases in CEO power and fewer new independent director appointments. Consistent with these changes not being beneficial for shareholders, we observe negative announcement returns to the appointments of new independent directors. We also show that firms carry out worse mergers and acquisitions after exogenous increases in passive ownership. These results suggest that the changed ownership structure causes higher agency costs.
