Abstract

We consider a platform marketplace with both third-party and platform-owned sellers. The platform charges commissions to third-party sellers and buyers for the transactions in the marketplace. Meanwhile, it also directly determines the transaction prices for platform-owned sellers in their sales to buyers. Sellers and buyers are divided into different types with the compatibility captured by a bipartite network. Different types of sellers and buyers are heterogeneous in their cost and utility functions. Given the platform's decisions on prices and commissions, buyers/third-party sellers maximize their own payoffs from demanding/supplying products, and market-clearing conditions are satisfied in the networked market. Facing the complexity with non-convex equilibrium constraints in the network, we develop a formulation for the platform's profit-optimal price-commission vector. Moreover, we investigate three other aspects of the revenue management problem. First, under fairness consideration between the platform and its market participants, we develop an efficient approximation algorithm to obtain a price-commission vector such that a fair allocation of surplus between the platform and its market participants is guaranteed in the equilibrium trades. Next, we shed light on how the platform should determine the optimal mixture of third-party sellers and platform-owned ones in the networked market. Lastly, we establish how the platform's profit-optimal price-commission decision depends on the network structure, and we further demonstrate the impact of network structure on the platform's optimal profit.
