Michael Sainato in his 18 Apr 2019 article for the Guardian quotes Maurice Stucke:
"Uber and Lyft profit from a lack of transparency on prices, noted Maurice Stucke, professor at the University of Tennessee College of Law and co-author of Virtual Competition: The Promise and Perils of the Algorithm-Driven Economy. 'There is an element of trust that we are relying on Uber to set the market clearing price, and to the extent Uber and Lyft have market power, that can be distorted,” said Stucke. “They can create the rules of the game, they can design the competitive process and they can ensure whichever driver makes more or less, whoever wins in the competition among drivers, they can be assured they’re always going to profit.'”
