Agreed, but unfortunately for someone our students’ age the 1990s are as far as the 1960s/1970s were for us, making it easier for them to pool the entire time period… and I also blame Spotify for mixing eras in a lot of rock playlists.

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.

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.

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...

This 👆. Has anyone figured this out? potentially big matching efficiency effects if people believe mkt is down… ie, lower ranked schools being too aggressive, candidates being insufficiently selective, etc.

2/2 Perhaps the bigger issue is “econ culture” as a whole - which rewards/incentivizes “complete” papers that give iron-clad answers with perfect methodology and data, over more incremental/imperfect research.

1/2 System as a whole (ie, academia) worked, but more narrow Econ ref process didn’t. Unfortunately, seems very hard to pick up, aside from the unrealistic (in retrospect) amount of work for a 2nd yr PhD.

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.

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%).
