Voice and power: Do institutional shareholders make use of their voting power?

I investigate the role of voting power – the ability to influence a vote's outcome – in the voting behavior of institutional shareholders. Using hand-collected data from Israel, an environment with concentrated ownership, I employ a power index borrowed from the political science literature to examine the voting power wielded by institutional shareholders and the voting patterns they display. I find that institutional shareholders' voting power is negatively related to their tendency to vote against management: the stronger the shareholder, the higher the probability they will vote in favor of a management-sponsored proposal. Based on evidence obtained here, this behavior is attributable to pre-vote negotiations as well as to the voting strategy of “counting on my vote not counting.” Next, I use detailed data on shareholders' votes to identify the channel through which a voting rule affects minority shareholder protection. I find that powerful institutional shareholders almost never use their voting power to vote against management, not even when signals of poor governance are discernible. I conclude that the effect of a voting rule on minority shareholder protection operates through proposal selection, rather than through direct voting.
