That first citation was partly written by Hal Singer. Singer was one of the key witnesses (ie economists) in the recent Within case and the courts basically rejected his theories outright. When I’ve got more time tomorrow I’ll post some of the other material that this piece doesn’t cite. The data isn’t as clean as this piece would suggest. In short, there is a big debate in economics about all of the items that they cite.
I would also look into this: https://www.washingtonpost.com/technology/2022/07/13/ftc-lin.... I often disagree with Commissioner Wilson but she has a point. The entire agency has shifted due to Chair Khan.
