My job market's done, and I'm heading back to the NYC area! Excited to join Princeton Econ as a postdoc next year and NYU Stern Econ as an AP in 2026.

In a happy twist of fate, this means @cconlon.bsky.social and I will be colleagues exactly 10 years after our first PyBLP commit:

Forthcoming at the Journal of Political Economy: We find that consumer product markups increased more than 25 percent from 2006 to 2019.

One contribution is an approach to estimate IO-style models at scale, yielding flexible consumer preferences and estimates of marginal costs.

what a story!

What will AI do to (p)research? AI makes doing and communicating research much easier. Will there be any point to it?

I used AI to help write a paper and got it published. All in record time. What does this mean for research? My latest post. open.substack.com/pub/joshuaga...

🙏to @UV_EG for hosting the conference

I've gotten a flurry of requests to access my slides on "Models, Measurement, and Language in Economics" (presumably thanks to the great new year's reading list from @rohitlamba.bsky.social). The file is publicly available via my web page, but here is the link: www.dropbox.com/scl/fi/ntgkb...

I'm honored that @wirtschaftswoche.bsky.social has included me in their list of "Germany’s 30 until 2030". When I first saw the title, I thought they’d gotten my age wrong—turns out it’s not *that* kind of list! Their initiative highlights optimism and innovation in 🇩🇪! Congrats to all awardees!

After a week of internal emails encouraging people to join BS (semi successful), my department now even has a starter pack!

Want to do a funded, joint Oxford-CMA PhD on market power?

Howard Smith (Oxford) and the CMA Microeconomics Unit are looking for promising candidates interested in doing research on the topic of "Beyond markups: understanding changes to competition, concentration, and market power".

Very much looking forward to my keynote speech on "Common Threads on Common Ownership" at the DICE Competition Policy Conference 2024 this Friday in Düsseldorf

Paper by Ryan Kellogg on oil and the green paradox below 👇

Other interesting and complementary paper on the role of strategic incentives is by our job market candidate Charlotte Decanniere:

“Pump it? Market Power and the Energy Transition in the Global Oil Market”

#econsky What is, in your opinion, the biggest question IO has credibly settled?

Seems most of our contributions are either (a) fancy methods; (b) negative results (e.g. don't regress price on HHI); (c) narrow in scope (yogurts, etc); or (d) contested (have markups actually risen?)

Here's a great starter pack for folks interested in the economics of innovation, competition and IO

Happy to share that my and @cconlon.bsky.social's micro BLP paper was just accepted at the Journal of Econometrics! jeffgortmaker.com/files/Incorp...

It's our 2nd tied to our PyBLP software, so here's a thread on surprising (to me) benefits of combining methods research with open source work. 1/6

After Neo-Brandeis - ProMarket Daniel Francis reviews the evolutionary and revolutionary dimensions of the Biden administration’s antitrust work, and argues that these two projects have been in deep tension. He concludes that the a...

I think my @nyulaw.bsky.social colleague Daniel Francis provides a clear and balanced summary of the Neo-Brandeis shift in antitrust.

It is worth a read for all IO Economists (and perhaps more importantly macro economists who've recently discovered IO).

I made a list of Dutch economists. Nice to follow for:
- journos (@marikestellinga.bsky.social, @mathijsbouman.nl etc)
- policy ( @wbcs99twit.bsky.social, @lukkezen.bsky.social)
- academics ( @robertdur.bsky.social, @basvdklaauw.bsky.social)

1st Berlin Micro Theory and Behavioral Economics PhD Conference This conference is dedicated to fostering discussion and collaboration among emerging scholars in the fields of microeconomic theory and behavioral economics.

#econsky, here is an interesting-looking conference for PhD students:

Thank you, Florian, for highlighting my job market paper! 🎉
You can read it here: drive.google.com/file/d/1Sqb1... Below, a short thread. 👇 (1/8)

Check out the great cohort of IO juniors on the market this year and if you are not on the list yet, make sure to sign up!

Female content creators on YouTube received significantly more negative feedback for comparable content.

But the removal of public display of dislikes eliminated this gender gap and persistently increased female creator productivity and consumer demand.

Hey #EconSky, I'm on the job market with an #EconJMP about open source software. OSS is a global public good, widely used and provided by the private sector, but the target of recent industrial policy.

Grateful towards our keynote speaker Chris Conlon, speakers, discussants, and participants! (who I struggle to tag but here on bsky)

Chris and his matrix to compress

That concludes our two-day Market Power workshop on Camille Jordan, Columbian hydropower and many equilibrium Constellations.

Do we do threads🧵on #EconSky? I recently gave a talk on competition policy and startup acquisitions. Here are the main points:

1/ Since ~2001, acquisitions have overtaken IPOs as the primary "exit" for VC-backed startups. This shift impacts how competition plays out.

Yes! And co-organized with my buddy (and coauthor) Theo @theodorf.bsky.social

And yes I agree, collusion can sometimes overcome a negative externality.. Sad to miss out on the CMA and FTC workshops

In what is clearly an example of insufficient collusion, there are three (!) separate workshops on market power this Thursday/Friday.

A new application for conglomerate effects merger control: the potential acquirer may destroy/sacrifice the target to curry favor with a future president and get new contracts for conglomerate businesses 🚀🚗

Investigating Markups: Evidence of Greedflation? Prices for consumer goods have rapidly increased in recent years. At the same time, some corporations are reporting record profits. Coincidence? A UVA economist’s research may offer some answers.

A summary of two studies that look at the supply and demand factors behind price changes in consumer products over the period 2006 to 2023. Touches on markups and inflation. Thank you UVA for featuring our research.
