Abstract: From a methodological perspective, this paper aims to review the various means to assess a competition agency?s merger decision. The upward trend to measure the efficiency of competition policy shows the utility of a survey about the main existing quantitative tools. To this end, four different approaches are exposed : simulation with structural models, event studies, the difference-in-difference technique, and lastly, surveys. One can ask if these tools often used during an investigation phase for a merger proposal can be transposed for a retrospective study. The pros and cons of such models are emphasized so that complementarities among them are possible.
