According to a new study (warning, PDF) released by Uber, yesterday, its Boston drivers - of which it estimates there are now 10,000 - are earning an average of $19 per hour, ~33-percent more than area taxi drivers and chauffeurs.
The study came under immediate criticism because its research was co-conducted in-house by John Hall, Uber Technologies' "Head of Policy Research", so, yeah, he had a conflict of interest. He has a doctorate from Harvard University, though, so there's that.
