Screening with Network Externalities
Abstract
Increasingly many products feature “network externalities”: the utility of one’s consumption increases in her neighbors’ consumptions. Although information of network structure is important to the seller, it is often privately known to the buyers. We model a monopoly’s (constrained) optimal pricing strategy to “screen” buyer’s network information: their susceptibility (out-degree) and influence (in-degree). We characterize the optimal allocation for both the case of directed networks where each buyer’s influence and susceptibility are independent, and the case of undirected networks where the two are identical. For directed networks, we show the optimal allocation can only depend on a buyer’s susceptibility and is linear in virtual type (of susceptibility) with quadratic intrinsic value. For undirected networks, we disentangle the different effects of influence and susceptibility on optimal allocation and show that with quadratic intrinsic value, the allocation is a linear combination of a buyer’s type and virtual type. We contrast the analysis with two benchmarks, the complete information pricing and uniform pricing, to shed light on the value of network information.
