It was used here by Jonathan Hall to provide context for his analysis of the MIT study on hourly wages.
No it wasn’t. This article links to a single Uber study, and it’s the Krueger one not this one. Edit: I was wrong here.
The primary finding of the study was that men are paid 7% more on the Uber platform than women. That’s what the media focused on, not the specific numbers. Insurance purchased outside of Uber is out of scope. You can take issue with that as overstating men’s effective difference, but Uber didn’t go out touting the absolute wages from that study, so it’s really not relevant.
