European Antitrust Policy 1957-2004: An Analysis of Comission Decisions

This paper provides a survey of european antitrust law enforcement since its foundation in the treaty of rome of 1957 up to and including 2004. We present a complete overview and statistical analysis of all 538 formal commission decisions under articles 81, 82, and 86 of the european community treaty. We report a range of summary statistics concerning report route, investigation duration, length of the decision, decision type, imposed fines, number of parties, sector classification, nationality, and commissioner and director general responsible. The statistics are linked to changes in legislation and administrative implementation, thereby providing an historical overview that summarizes the commission’s work in the area of antitrust. One or more appeals were filed with respect to 161 of the 538 decisions. We estimate the determinants of the size of the imposed fine and probability of appeal when an infringement has been found
