The VCG pricing policy with unit reserve prices for ride-sourcing is [Formula presented]-individual compatibility

We consider a customized matching and pricing mechanism for ride-sourcing services in which drivers and riders disclose their willingness to accept (WTA) per unit distance and their willingness to pay (WTP) per unit distance, respectively. The platform the ...
