🌞Summer is upon us, and it's Summer Institute time. For this year's Summer Institute in Competition Policy, we went to Bad Homburg (June 2-6) MaCCI researchers and invited scholars presented a diverse array of theoretical and empirical work in the field of competition economics.

If it's May, it's time for the #MaCCI IO Day. We had our annual IO workshop this Friday, with research from @zew.de and @econunimannheim.bsky.social Vertical restraints, environmental regulation, innovation, search, platforms, IPOs. We covered a lot of ground!

Rückblick auf die #MaCCI Jahreskonferenz 2025 am #ZEW: Experten/-innen diskutierten über Ordoliberalismus, #M&A-Effekte, #Wettbewerb und Konsumentenpreise bei Fusionen. @macci-mannheim.bsky.social #EconSky Zum Nachbericht ➡️ www.zew.de/PM9400/?twt=1

First was a thought-provoking talk by Pablo Ibáñez Colomo on the prescience of ordoliberalism (aka neo-Brandeisianism) and the challenges to that approach moving forward at @macci-mannheim.bsky.social www.youtube.com/watch?v=vN1Y... (2/9)

Next was a great talk by Nancy L. Rose on the state of the literature on efficiencies in mergers at @macci-mannheim.bsky.social. I would've liked to hear more on the inherently subjective/political nature of market definition, but it's still a good review www.youtube.com/watch?v=oSm4... (4/9)

Did you miss the keynotes at this year's MaCCI Annual Conference? Despair, do not! The recordings are online now: Nancy Rose on efficiencies in merger analysis youtu.be/oSm4qEf9VSQ?... Pablo Ibáñez Colomo: "Towards the end of the Ordoliberal compact?" youtu.be/vN1Y1piJgw0?... #EconSky #EconConf

On the way back from a great @macci-mannheim.bsky.social conference! Excellent keynote by Nancy Rose between many other inspiring talks 👏👏👏

Nancy Rose's keynote on efficiencies in merger control. Inspiring! One of the highlights of this year's annual conference

Bei der #MaCCI Jahreskonferenz 2025 am #ZEW beleuchtet Nancy L. Rose @mitofficial.bsky.social in der zweiten Keynote die wirtschaftliche Bedeutung von Effizienzgewinnen in der Fusionskontrolle. Ein zentrales Thema für die #Wettbewerbspolitik. @macci-mannheim.bsky.social

Our morning panel on the challenges in the regulatory framework of merger control is ongoing. Powered by Studienvereinigung Kartellrecht, with Philipp Pichler, Alexander Rinne, and Carsten Grave #EconConf #EconSky #LawSky @zew.de

As in previous, I got to watch (with occasional Q&A) the conference orga (program and logistics) from the sidelines. It is thanks to the local team with @stenzhorn.bsky.social, Lion Holste, and the @zew.de conference secretariat that the MaCCI annual runs as smoothly as it does. 👏🎉 THANKS!
