The moment is now. Europe stands at a crossroads: 💊 Blue pill: Path dependency, decline, and irrelevance. 💊 Red pill: Rebirth, dynamism, and a new industrial revolution 5/6

These myths are holding us back. Europe must confront trade-offs, face empirical reality, and make the hard choice: prosperity over stagnation 4/6

Our message is simple: Less, Better. Europe doesn’t need more regulation, more bureaucracy, or more mission creep. It needs to focus on what made it great: economic dynamism, open markets, and a culture that rewards innovation 2/6

It’s that time to repost “understanding market power” - a full guide to the tricky but essential economics behind antitrust law. If you teach or study antitrust this fall, feel free to use it. Feedback is very welcome to help me improve the next version papers.ssrn.com/sol3/papers....

Encouraging to see Brussels push back on political interference in legitimate bank M&A. Less ideal that consolidation is unfolding along national lines. The big question: will stronger national champions finally unlock real cross-border banking in the EU?

Can’t be true! Legal scholars claim Amazon dominates without rivals. Economists claim algorithms collude. When theory fails to match reality… ignore reality?

As @jeffjarvis.bsky.social might say: blaming the decades-old collapse of local journalism on one company - no matter how big - is grotesque. Correlation isn’t causation, even if you’ve got a Nobel Prize.

The antitrust cases in @FTC v Meta and US v Google are strong examples of a phenomenon known in economics as 'time inconsistency'. What seems like efficient correction today may lead to unintended economic distortions tomorrow. A thread 🧵1/n.

Quick puzzle on the US v Google remedy trial. Press coverage suggests the Government's focus is as much punitive/deterrent as restorative. So why is the Gov pushing for a breakup? From a legal standpoint, there are better options than breakups for punishment or compensation 1/n

Interesting new GenAI feature that Meta rolled out on WhatsApp. As I wrote in my 2020 book, winner-takes-most dynamics in digital often arise from a process of competition *for* the best User Interface (UI) #AI 1/n

I am less keen on Acemoglu’s proposal to tax big tech firms. Antitrust enforcement is more effective in curbing monopoly rents in tipped markets. 31/N

For example, I am in favor of limiting digital advertisements in specific settings, similar to TV ad regulations in Europe. 30/N

The notion of numerous small firms competing in places like the Bay Area is largely true. Our paper, Gatekeepers, Landlords, or Superstars (w/ Bo Heiden & Sotiris Georgoudios), examined this phenomenon papers.ssrn.com/sol3/papers....

The @financialtimes.com recently featured a piece asking if France, and Europe, could become “a global AI powerhouse”. The FT piece has clear connections with the Draghi Report's embrace of a form of ‘European Preference’ 🇪🇺 in the chapter on competition policy. #AI #DraghiReport 1/n

Nicolas Petit @competitionprof.bsky.social · 02/01/2025

What I meant a few days ago by EU preference is an exorbitant law and policy approach supportive of domestic AI ecosystems like Station F and firms like @mistralai.bsky.social 1/n

🤯 that even with Trump’s bad economic policies, “most economists — including at the IMF, the OECD and the European Commission — forecast stronger growth in the US than in Europe in 2025”. #draghi #competitiveness

Wanna set the record straight on the investment commitment remedy proposed by Draghi for mergers. Some online commentary has cast doubt on the idea of an investment commitment by quoting portions of Sir John Vickers' Keynote Lecture at the Association of Competition Economics: lnkd.in/d6neyNJp 1/n

🎯Unforced error of the times from competition economists. Believing the #Draghi report lacks theory or evidence on why 📍 ‘where capital is located matters’ for productivity & prosperity. 🧐 The econ literature suggests substantial spillovers to R&D, listing, and even HQ location 1/N.

The U.S. Department of Justice deserves praise for its proposed remedies in US v. Google. Imagine you're in your study, thinking about how to build or help a rival general search engine. You’d likely come up with a plan similar to the DoJ’s 1/N
