We’re delighted to share that @IoannisLianos gave the keynote at the UN’s global competition & consumer protection conference in Geneva, calling for an “agile competition law” to keep pace with rapid digital change and tackle fragmented enforcement.

Amazing workshop at @UCLLaws yesterday. I presented my joint work w/ @sarafish_ @YannaiGonch in panel w/speakers from @EU_Commission @CMAgovUK @Adlc_ @ea_hcc. So gratifying to see our research makes positive impact in the world. Thanks much @IoannisLianos for inviting us!

WORKSHOP ALERT: Following the inception report of the HCC on computational competition law and public policy back in 2021 (the first report on this issue released by a competition authority) and last year's successful workshop I am happy to announce the second edition of the CLES@UCL workshop on Computational Competition Law and Public Policy, which will be held on Thursday, June 19th at UCL Laws. In the programme this year:
- Horizon scanning: AI tools in competition authorities and regulators. Case study: dealing with algorithmic collusion
- Computational social science and causal inference/reasoning for public policy purposes: LLMs, multi-agent AI systems and in silico law approaches, Agent-based modelling, complexity science and digital twins
Registrations and further information here: ucl.ac.uk/laws/events/2025/j…

A recent paper co-authored by several Stigler Center-affiliated scholars, including @BarriosEcon, @JoshuaYLevy, @shashankss09, @TomValletti, and @zingales discussed how conflicts of interest impact the trustworthiness of economics research. Together with @UCL_CLES, @GeorgetownLaw, LobbyControl, @ImperialCollege, and @Inclusive_Comp, we also co-organized a conference in Brussels to discuss how corporate relationships impact antitrust scholarship.
We also instituted a disclosure policy at #StiglerAntitrust25: promarket.org/2025/04/08/sti…

Such an important point on the state of antitrust scholarship from @MeadorFTC! Academic whitewashing on behalf of the largest corporations needs to be addressed.

NEW PAPER: New Industrial Policy Design and Competition: A Computational Approach
Large empirical study of more than 2000 industrial policies between 2015-2023, examining the prevalence of techno-nationalism over techno-globalism among the major jurisdictions (China, US and UK - but not in the EU!) and exploring how (in)compatible techno-globalist or techno-nationalist industrial policies are to competition and for which parameters. papers.ssrn.com/sol3/papers.…
