The Global Merger Control Index 2013

For the fourth consecutive year, the Center for European Law and Economics has conducted an extensive survey of legal experts to construct the 2013 Global Merger Control Index. The index compares 65 jurisdictions based on the responses of 192 legal experts, specialising in competition and anti-trust.

The Global Merger Control Index (GMCI) is a part of (, an ongoing research project on international merger control. The GMCI is based on a survey which asks respondents to asses a number of aspects of their jurisdiction’s anti-trust system. The goal of the index is to enable both cross-sectional and longitudinal comparison of merger review legislation/systems worldwide.
