Using a large sample of partial block acquisitions, we examine the importance of geographic proximity in corporate governance and target returns. We find that block acquirers have a strong preference for geographically proximate targets and acquirers that purchase shares in such targets are more likely to engage in post‐acquisition target governance activities than are remote block acquirers. Moreover, the targets of these acquirers realize higher announcement returns and better post‐acquisition operating performance than do targets of other types of acquirers, particularly when they face greater information asymmetries.

Using block share acquisitions made by private equity (PE) funds, we examine the sources of value gains in PE minority equity investments. We find that compared with non-PE acquirers, PE acquirers are more likely to place representatives with finance experience or those with experience in the target's industry on the target's board when the need for target oversight and/or advice is higher. The targets in PE acquisitions, particularly poorly performing targets, targets with high R&D intensity, and targets with PE-appointed directors who have experience in the target's industry, realize both higher announcement returns and better post-acquisition operating performance than do targets in non-PE acquisitions. These findings suggest that the governance and operational engineering that PE acquirers apply to their targets constitutes important sources of value creation in PE minority equity investments.

We examine the informational role of geographically proximate institutions in stock markets. We find that both the level of and change in local institutional ownership predict future stock returns, particularly for firms with high information asymmetry; in contrast, such predictive abilities are relatively weak for nonlocal institutional ownership. The local advantage is especially evident for local investment advisors, high local ownership institutions, and high local turnover institutions. We also find that the stocks that local institutional investors hold (trade) earn higher excess returns around future earnings announcements than those that nonlocal institutional investors hold (trade).

We examine whether firms belonging to Korean business groups (chaebols) benefit from acquisitions they make or whether such acquisitions provide a way for controlling shareholders to increase their wealth by increasing the value of other group firms (tunneling). We find that when a chaebol‐affiliated firm makes an acquisition, its stock price on average falls. While minority shareholders of a chaebol‐affiliated firm making an acquisition lose, the controlling shareholder of that firm on average benefits because the acquisition enhances the value of other firms in the group. This evidence is consistent with the tunneling hypothesis.
