That’s all for this year’s #BruxConf2023. Thank you to everyone who attended and watched on the live stream. @Caffar3Cristina

Olivier Guersent explained second challenge in mergers: remedies must be more demanding and rigorous. There’s a continuum. Quasi-structural remedies may be preferred to prohibition - not ashamed by Google/Fitbit remedies @Caffar3Cristina #BruxConf2023

Olivier Guersent: what defines the transactions of tomorrow are transactions below notification thresholds. Article 22 most economical way to achieve flexibility on these thresholds without additional burden on firms @Caffar3Cristina #bruxconf2023

Olivier Guersent : competition policy can help but not substitute for industrial policy. Continuing the ducks metaphor, Antitrust is like shooting ducks of yesterday. @Caffar3Cristina #bruxconf2023

Olivier Guersent will cover : 1) competition policy and other policies 2) #dmadsa 3) changes in merger control. @Caffar3Cristina #BruxConf2023

Final concluding fireside chat now with Olivier Guersent @Caffar3Cristina #BruxConf2023

Ariel Ezrachi (@ArielEzrachi): ex ante regulation = “aiming ahead of the duck”. Focus should NOT be on symptoms.Innovation mentioned all the time but very difficult to predict - retain qualitative approach as millions also spent on toxic innovation @Caffar3Cristina #BruxConf2023

Cory Doctorow (@doctorow) things have got worse - digital platform economics: consumers locked in > surplus transferred to business users > but then to shareholders. Surplus reallocation = Facebook “inshitification” @Caffar3Cristina #BruxConf2023

Alberto Bacchiega: Either antitrust and regulation will make #bigtech better together or no-one will get there. Will be judged by businesses and consumers - if no impact then will have failed @Caffar3Cristina #BruxConf2023

Stéphanie Yon-Courtin (@s_yoncourtin): DMA/DSA telling big tech what they can do or not. “It’s over” for them. #elon_musk must respect the rules. But don’t count your chickens before they hatch- could #bigtech’s new practises be harmful? @Caffar3Cristina #BruxConf2023

Again a fantastic conference @BruxConf2023, many thanks for putting together this stellar line-up @Caffar3Cristina! Special thanks also to my co-panelists Andrea Coscelli, @TomValletti, Barry Lynn @openmarkets, @johnmarknewman and @rodgsims for our stimulating exchange.

“Making Big Tech Better vs Making it Smaller:Will Antitrust or Regulation Get There First?”-Ken Paxton (@KenPaxtonTX), Stéphanie Yon-Courtin (@s_yoncourtin), Cory Doctorow (@doctorow), Alberto Bacchiega, Ariel Ezrachi (@ArielEzrachi), Filomena Chirico (@FiloBXL) @Caffar3Cristina

Coming up: A conversation with Ken Buck (@RepKenBuck) and Marco Iansiti (@marcoiansiti) discussing Online Harms, AI & Democracy @Caffar3Cristina #BruxConf2023

Sarah Cardell (@CMAgovUK): Need to assess both dynamic competition & potential competition. Analysis needs to be grounded in commercial reality. Labels (eg flywheel etc) don’t matter. Inherently a judgement that needs to be made. @Caffar3Cristina #BruxConf2023

Pierre Régibeau: Existing modern economics offer a rich set of tools. Nothing new about killer acquisitions. 1) New concern in tech is really “early acquisitions”. 2) conglomerate theories of harm- needs numerical evidence. @Caffar3Cristina #BruxConf2023

Susan Athey (@Susan_Athey): need to 1) Recognise common fact patterns;2) monopsony power a live concern;3) explain why market definition is less meaningful in some areas, but helpful to focus attention on harmful conduct. @Caffar3Cristina #BruxConf2023

Susan Athey (@Susan_Athey): Modern economic thinking is crucial. Helps frame and investigate complicated conduct smartly. This thinking is infused in the new guidelines. Echoes Aviv Nevo who was earlier on the panel. @Caffar3Cristina #BruxConf2023

Aviv Nevo: complex models deliver insight - cases rarely lost on theory but lack of evidence & data. Need facts to convince courts. Call to arms - need folks to come & fight in the trenches “take off your fancy suits”!@Caffar3Cristina #BruxConf2023

Aviv Nevo (FTC): “We don’t need less economics, but more”. Right kind of economics to organise thinking. We need a “modern” view that looks at a wider set of theories of harm, not just short term price effects. @Caffar3Cristina #BruxConf2023

Bruno Pellegrino (@BPellegrino_UMD): Hybrid IO-macroeconomic view: need to look across many different sectors. Network theory of market power- an economy is a network made up of nodes (products). Distribution of centrality in the network indicates concentration @Caffar3Cristina
