But it raises the question: why doesn't Uber operate like a normal marketplace where buyers/sellers submit bids/offers at prices of their own choosing?
By preventing buyers/sellers from participating in price discovery, Uber makes itself look a lot more like a classic employer/vendor than an online marketplace.
But stores bear product liability for dangerous products, vicarious liability for employee misconduct, and are bound by employment/labor law.
You can't claim to be a flea market when you are really a store.
That college student can sign up for short shifts, after all. You can allow folks to self-schedule. I*m pretty sure Uber already rates folks, in part, by their availability to drive.
Sort of. If you have actual employees you need to pay for benefits. Someone who only works a few hours a day may not bring in enough revenue to cover the cost of their benefits, so the employer may need to require longer, less flexible hours in order to make it worth hiring someone in the first place.
What if there were another purpose to the flexibility, to apply that 'two hours and fifteen minutes' of time the college student had to capturing the market value of shuttling people around campus and nearby, rather than stationing some 40-hour/week employee near campus, hoping to have them utilized all 40 hours?
