This article surveys the literature dealing with the economic analysis of mergers. We first emphasize the Williamson model which constitutes the pioneer attempt to analyze the economic consequences of horizontal mergers. In a second step, we show how the development of new economic tools helps refining the analysis by taking into account the strategic behavior of the firms. Finally, in the last section, we set the basis of the analysis of mergers in a context of asymmetric information.
