Professor - and fellow AT blogger - D. Sokol is currently conducing a survey on the compliance effects of the antitrust laws. Private practitioners and in-house counsels are invited to answer a set of questions which, undeniably, have "important policy implications".
On a personal note, I am very much in favour of the introduction of empirical techniques in antitrust law and economics (i.e. through surveys, for instance). The numerous consultations processes launched under the impetus of the Commission are nothing but empirical methods. Yet, the Commission's questions are often so vague and open-ended, that many addressees will be discouraged from inputting (the recent consultation process on the ex post assessment of Regulation 1/2003 is a case in point). Transaction costs matters to potential respondents. Failing to understand that inevitably leads to low participation and, in turn, poor feedback. In simply requiring 8-12 minutes to fill, Prof Sokol's survey avoids this shortcoming.
