NEW: How did the introduction of the Ultra-Low Emissions Zone (ULEZ) change London’s geography of work? In a new @theifs.bsky.social paper, @joelkariel.bsky.social, Fizza Jabbar and I have taken a look – and it turns out people adapt in surprising ways. A thread. 1/

I wanted dinner recommendations so I scraped 13,000+ London restaurants and accidentally discovered Google Maps is running a shadow economy. Anyway here's a dashboard and a political economy thesis: open.substack.com/pub/laurenle...

A.I. Might Take Your Job. Here Are 22 New Ones It Could Give You. @robcapps.bsky.social wrote an excellent article @nytimes.com with views from yours truly, @emollick.bsky.social, @erikbryn.bsky.social and others. www.nytimes.com/2025/06/17/m...

@ershovd.bsky.social, Yanting He, & Stephan Seiler analyse over 100 million tweets from 2014 to 2021 and find that the vast majority of commercial content on social media is not appropriately disclosed by the influencers who post it. cepr.org/voxeu/column... #EconSky

WHAT HAPPENS WHEN A DOMINANT PLATFORM SUDDENLY MODERATES A LARGE SHARE OF ITS CONTENT? 🚨 With Matt Mitchell, Martin Quinn & @mikybartoli.bsky.social, we study one of the largest moderation shocks ever: Pornhub’s 2020 purge of 10M+ non-verified videos (80% of content). 🧵👇

Pornhub's removal of all non-verified content led to a 41% drop in traffic within 1 month. Much of the displaced traffic was absorbed by competing platforms, including less regulated fringe websites (+55% visits) and mainstream competitors (+10%). papers.ssrn.com/sol3/papers....

Hi, #EconSky! I’m Anderson, a 6th year PhD candidate at the University of Virginia. For those going to ASSA this week, I’ll be presenting my job market paper, The Effects of Privacy Regulation on the Supply of Stolen Data, during the CSMGEP session tomorrow at 8AM. Here’s a short thread about it

#eeac Day 13: @tfwerner.com JMP on algorithmic vs. human collusion is of course terrific; his paper on LLMs steering consumers is also worth a look arxiv.org/pdf/2409.12143 "Using a behavioral experiment, we show that [LLMs] can indeed significantly shift consumer preferences." #econsky #econjmp

To be fair, this does get at the real issues related to new information aggregating/ disseminating technology [which are mostly unrelated to the nutty replies to Kevin's thread]. Citing Wikipedia is NOT the equilibrium now, & it's used precisely in the way that the Middlebury history profs wanted.

That's a revealing read. Thanks for posting, Igor! I guess the pattern is clear. Productivity-enhancing innovations (in the case of Wikipedia it was crowdsourcing) are met with hostility because their first-order effects are perceived as labor-saving. The term "Luddite" is not too far off.

Why do I think these instances are interesting? To me, these are not just random instances that LLMs are sometimes wrong (like people), these are *diagnostic* that LLMs do not have a world model and are not “reasoning”, it exposes the basic architecture. Why? 1/n

Reposting this to remind myself to re-read this paper later.
