Dear Colleague, Please be reminded of the deadline for the 2023 Annual Conference of the Mannheim Centre for Competition and Innovation (MaCCI). The conference will take place at the ZEW in Mannheim on 23 and 24 March 2023. A large portion of the conference will be devoted to parallel sessions in which original research papers from all fields of competition law and economics can be presented. The parallel sessions will also include papers on business strategy related to competition, on the intersection between competition and innovation, and on regulated industries. Theoretical, empirical, as well as case-oriented papers are welcome. In particular, we invite legal scholars to submit papers focusing on EU competition and/or comparative competition law. In addition to the contributed sessions there will be two keynote lectures. All individual submissions must include the following information: an abstract of up to 200 words, the author’s full name and affiliation, as well as contact details. Please submit only full papers (incomplete drafts are welcome). We also encourage submissions of full sessions. Any such proposal must include a short session abstract and the papers (or extended abstracts thereof) to be presented in the session itself. Typically, a session comprises three papers and all presenters should have confirmed their willingness to participate. All proposals must be written in English and shall be submitted to the organising committee via MacciAnnual2023@zew.de <mailto:MacciAnnual2023@zew.de> as a PDF file no later than 30 November 2022. Participants interested in discussing a paper without presenting should send a message to the organising committee. Authors of accepted papers will be notified no later than 31 December 2022. Presenters must register by 15 February 2023 and may be asked to discuss another paper. Young researchers are particularly encouraged to submit papers. More information is available at www.zew.de/macciannual2023 <http://www.zew.de/macciannual2023>. We look forward to your submissions.
