We examine the separation of ownership and control for 2,980 corporations in nine East Asian countries. In all countries, voting rights frequently exceed cash-flow rights via pyramid structures and cross-holdings. The separation of ownership and control is most pronounced among family-controlled firms and small firms. More than two-thirds of firms are controlled by a single shareholder. Managers of closely held firms tend to be relatives of the controlling shareholder's family. Older firms are generally family-controlled, dispelling the notion that ownership becomes dispersed over time. Finally, significant corporate wealth in East Asia is concentrated among a few families.
