Upward Pricing Pressure in Partial Acquisitions: Application to the Essilor Case

The price effects of a partial acquisition may be far more complex than those of a full merger. The discussion on this issue, however, has not been well developed in Asian countries, including Korea. However, a partial acquisition case occurred in Korea in which Essilor intended to acquire fifty-percent shares of its competitor, DM Optical. In this paper, we modify and reorganize theories of upward pricing pressure (UPP) in partial acquisitions and apply them to this case. This paper, therefore, intends not only to initiate a discussion, but also to suggest an exemplary method to conduct UPP analysis in partial acquisition environments. Specifically, it will contribute to methodological advances by analyzing the case in a fashion that circumvents limitations of time and data, the main obstacles merger reviewers often face, in practice.
