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...

How Google Maps quietly allocates survival across London’s restaurants - and how I built a dashboard to see through it
I wanted a dinner recommendation and got a research agenda instead. Using 13000+ restaurants, I rebuild its ratings with machine learning and map how algorithmic visibility actually distributes power.

@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
Graph of the distribution of annual brand-level non-disclosure rates.

Social media influencers have become a powerful advertising channel, but social media advertising is still little regulated, with limited enforcement of disclosure regulations. This column analyses over 100 million tweets from 2014 to 2021 for disclosure rates. The findings suggest that the vast majority of commercial content on social media is not appropriately disclosed by the influencers who post it. Consumers are not able to distinguish commercial and non-commercial content absent disclosure labels. These results indicate the need for additional regulatory scrutiny of undisclosed advertising online.

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....

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.
