Abstract: Ride-sourcing companies such as Uber, Lyft and Didi Chuxing are transforming the way people travel in cities. The services these companies offer have enjoyed huge success but also created many controversies — one of them centered on dynamic (surge) pricing. In this talk, we present an aggregate, equilibrium modeling framework for ride-sourcing markets with a focus on evaluating temporal and spatial effects of dynamic pricing. Our modeling framework features the equilibration of demand and supply, while explicitly capturing the advanced matching technology that a ride-sourcing platform adopts to match customers and drivers. The framework can be tailored to addressing key modeling considerations in different dimensions such as the spatial distribution of vacant vehicles and drivers’ work scheduling behaviors. The tradeoffs in the welfare of different market players under dynamic pricing and possible management policies will be discussed based on the equilibrium outcomes.
