Am Dienstag, den 12.04.2022 um 18 Uhr s.t. begrüßt der ECONtribute Law&Econ Workshop Lisa Bruttel von der Univeristät Potsdam zum ersten Vortrag des neuen Semesters. Der Workshop findet wieder in Präsenz statt (Raum 0.017 Juridicum). Sie wird ein experimentalökonomisches Papier zu unterschiedlichen Beurteilungsmaßstäben bei der Anwendung des Kartellrechts vortragen. Der Titel lautet: "A comparison of the per-se approach and a judgment by effect in competition law".

Abstract: In their judgment of whether firms should be fined for having formed a cartel, courts often rely on a per-se approach because collusive pricing is difficult to prove in practice. However, compared to a judgment of the firms’ collusive attempt based on its effect on the market outcome, the per-se approach comes at the cost of increasing the probability of misjudgments. These potential misjudgments might change firms’ incentives to collude ex-ante. In this paper, we compare firms’ price setting behavior under a per-se rule and a judgment by effect, controlling for the communication content using machine learning techniques. Our results suggest that the costs caused by misjudgment are relatively low: firms’ coordination at high prices is mainly driven by the mutual decision to communicate but only very little by the content of communication.

Der Vortrag findet in englischer Sprache statt. Die Organisatoren freuen sich auf zahlreiches Erscheinen!
