🚨Free data alert!! 🚨 Please share.

Large new dataset of Amazon product reviews, including full text and photos and product characteristics, with individual *reviews labeled as fake reviews*.

I believe this is the first publicly available data of this kind.

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.

How did the system work? It was an R&R at the QJE (allegedly) so the economist reviewers clearly had no idea.

@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.

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%).

Guess where they got their weird trade deficit math from?
A tweet by "rohit" discusses the application of AI in geopolitics, specifically focusing on tariffs, and includes a table comparing tariff rates between China and the US.

Next big thing for brands: knowing what sites agents prefer.

Operator loves buying from the top search result on Bing. Claude has direct preferences like 1-800-Flowers

We don't know why
