Motivated by the proliferation of food delivery platforms, such as DoorDash, Uber Eats and Meituan-Dianping, that match restaurants, customers and delivery drivers over a geographically dispersed network, we study the platform’s joint pricing, staffing and routing problem under endogenous participation of all three sides. Using a state-dependent queueing model where the service rate depends on the imbalance of the three sides due to spatial frictions, we study the equilibrium behavior of a large system in heavy traffic and show through asymptotic analysis how the platform controls balance capacity utilization and service quality. We show the platform’s value is threefold: (i) increased market output as the platform boosts demand for restaurants and offers faster delivery; (ii) delivery resource pooling that saves the restaurants’ logistic costs and increases deliverer utilization; (iii) efficient network routing that reduces cross-location pickups, hence customer waiting and deliverer idleness.
