Uber wants to enter a new city. The city has an established taxi industry and policies in place to manage pollution, congestion, housing, and new development. What "private parties" are supposed to do the cost-benefit analysis here? Obviously it's in Uber's interest to move in, but what if that increases pollution or the livability of the city to the existing residents? There are no private parties that are in a position to do a credible and representative analysis of the costs and benefits.
