When a focal subsidiary is underperforming relative to industry peers or overseas subsidiary peers, its parent MNC tends to change its ownership of foreign subsidiaries and by a high degree.

The M-P relationship has been the topic of many articles in many journals for many years, but its true nature is still not established. Both theory and empirical findings provide different and often opposed views, as can be seen in the articles collected here. We see two main perspectives on this issue. Some scholars suggest that differences in data and analytical tools have prevented consistent empirical results, and that more consistent and carefully chosen empirical modeling can yet establish the true M-P connection. Others believe that basic problems in theory and in building testable frameworks that are truly consistent with theory have made this an inherently intractable problem. The collection provides important articles that test the M-P relationship as well as critiques from both perspectives. We see considerable power in the view that individual firms are likely to have their own idiosyncratic optimal level of multinationaliation.
