Using a unique, hand-collected data sample and panel-data econometric techniques, we analyse the impact of founding-family control and intergenerational succession on the value of Chilean listed companies. After controlling for firm- and ownership-specific characteristics, we find an inverse U-shaped relationship between a founding family’s degree of ownership and firm value. Hence, family ownership at first increases firm value. However, when family ownership exceeds a threshold of about 38 percent of outstanding shares, the family takes advantage of its power in the firm and extracts wealth from minority shareholders. Further, if the founder of the company is the CEO or chairman of the board, firm value increases. However, family businesses with a subsequent-generation owner-manager destroy value.

Using a sample of 595 firms listed in the capital markets of Argentina, Brazil, Chile, Colombia, Mexico, and Peru for the period of 2000---2015, we confirm prior literature by showing that when power distribution among several large shareholders (contestability) increases, firms’ financial performance is enhanced. More interestingly, we find that these relations are even more significant in family-owned firms, emphasising the relevance of contesting control in this kind of firm. Furthermore, contestability has a greater influence in family firms that have the most concentrated ownership. We also find that the legal framework attenuates the impact of the balance of ownership. Here, contesting control acts as an internal corporate governance mechanism that provides an alternative to the external legal setting. Taken together, our results mean that in institutional settings characterised by weak investor protection and possible conflicts of interest among shareholders, oversight by multiple large, non-related shareholders (balanced ownership concentration) becomes an important governance mechanism.
