Today, I am excited to release a paper that has been five years in the making, titled “Endogenous Firm Ownership in General Equilibrium.” I think it is the best thing I have done. www.nber.org/papers/w34187

Very proud of this honour and to be in some great company.

I was thrilled to join Emanuele Tarantino, Susan Athey, Cristina Caffarra & others for CEPR’s webinar on “Updating Merger Control as an Economic Policy Tool for Europe?”

How can merger policy adapt to support innovation, growth & strategic autonomy?

To honour the memory of Ghazala Azmat, the Department of Economics of SciencesPo is creating an award in her name. Ghazala made important contributions in a large number of fields, spanning the economics of discrimination, gender, education and organizational economics. The award will promote work in those fields by young scholars. The first edition of this award will consist of a 5,000 euro prize for the best paper in this set of fields by junior researchers. The selection of the laureate will be carried out by a scientific committee composed of Pierre Cahuc, Alan Manning and Barbara Petrongolo. Eligibility for the prize requires that all authors have obtained their PhD after 1 September 2018. Papers written jointly with more senior researchers will not be considered. The prize will be awarded at SciencesPo during the event organised in memory of Ghazala on 10 December 2025. One of the authors of the prize winning paper will present the work at this event. Applications must be submitted by 31 August 2025.

Many thanks for including me. Great program, interesting people, and lots of food for thought.

This put it well for those not lucky enough to have known Ghazala www.eeassoc.org/news/memoria...
She made us all better.
Truly devastating.

I love the Economic Journal referees ❤️
Revised version of a paper received on April 15. Sent out to original reviewers on the same day. All four referees have come back to me in less than 10 days.
Paper is now conditionally accepted, subject to checks by the EJ Data Editor 🚀 @resmedia.bsky.social

the last one is true?
maybe time for a new schtick?
time to write papers ...

I started suggesting that this is probably good advice (for an author) but depressing (socially costly in establish norms of what a paper is supposed to look like). Just one more example to add to prisonners' dilemma examples in class. A third party (e.g. editor) in principle can help internalize

I guess it depends on whether you think that the costs of producing (and reviewing) this length are neglible or not in relation to any (positive?) social value that they may generate.

Probably the right advice for authors (and may be right as first point), but point 1 is depressing as heck to me and why we get these massive unreadable tomes. I'd like to think that editors (try to) fight back on trying to get to essential points and readable papers; but fighting norms is hard.

TSE is putting together an IO and Finance conference in October, submissions now open and details at www.tse-fr.eu/conferences/...

There's a link in that article to a radio interview with Meg on CBC which is as frank and clear as you would expect.

Time to first decisions at The Economic Journal academic.oup.com/ej?login=true. Thanks to all the hard work and efforts of the referees, AEs and other editors. Please submit your excellent papers and expect an efficient and thoughtful response.

My old roommate at Oxford switched from law to Sanskrit for undergrad and made a fortune from countless scholarships for which he was the only qualified applicant; obviously in PE now 😂

Folks have put together starter packs of folks to follow. Here is an example bsky.app/starter-pack... but I would search for other topics for people you might be interested in.

On the second there’s work on boundedly rational managers (I have in mind an old paper of Mo Xiao and Avi Goldfarb) that may be relevant but I haven’t really kept track of either literature.

On the first part there’s an old IO literature on conduct parameters that is about the objective function (are we maximizing individual profits or colluding). I think Chris Sullivan at Wisconsin is a more recent contributor and could find more.

and I guess that last example suggests that conformity is not inconsistent with competition... good ideas diffuse (and sometimes people too: RES has now lost data editors to both the AEA and ES).

Also forgot data editors and replication checks which is a big and relatively new innovation that was introduced and rapidly became a norm

Publication lags (a year or more used to be normal) advice to referees (has become pretty standard but is a fairly recent innovation). To me a lot of unease and dysfunctionality is the status obsession and tyranny of top 5 and I don’t see much that moves the needle

I guess I’m old. We’ve had attempts at tiered journals (BE press a million years ago now to some extent the society suites) transferring reports (EJ, AeA suite, ES, JPE), term limits (EJs), attempts at new blood (JPE), up or out processes (economic inquiry), short form outlets (insights …)

How can we get genuine competition (among journals? societies?) to generate ideas (as has been the case for many of the proposals: term limits, sharing reports, advice to referees etc)

What is the market failure? why do we think the solution is centralized committee and coordinated behaviour? What do we think the friction is that gets in the way of competition?

Omer should be a day-one follow for Econ and Evolution theorists, macro folks, and anyone who cares about integrity in the profession or in Science generally.
