European Merger Control


Time period

1990 - 2007

Unit of observation

368 mergers


The Data are partially proprietary


The sample includes 368 merger cases scrutinized by the European Commission from the beginning of 1990
to the end of 2007. It contains almost all phase 2 mergers and a randomly matched sample 
of phase 1 merger cases. For each merger, the dataset contains information on the identity
of the merging parties, their rivals, relevant markets, decision types, the dates of
the notification, phase 1 and possibly phase 2 decisions, and some other merger-specific
characteristics. Moreover, for each merger the dataset contains the cumulative average abnormal
returns for the merging firms as well as for their rivals.
