Optimal Sales Schemes for Network Goods

Alexei Parakhonyak (National Research University Higher School of Economics, Moscow) and Nick Vikander (University of Copenhagen, Department of Economics) explore Optimal Sales Schemes for Network Goods.

ABSTRACT: This paper examines the optimal sequencing of sales in the presence of network externalities. A firm sells a good to a group of consumers whose payoff from buying is increasing in total quantity sold. The firm selects the order to serve consumers so as to maximize expected sales. It can serve all consumers simultaneously, serve them all sequentially, or employ any intermediate scheme. We show that the optimal sales scheme is purely sequential, where each consumer observes all previous sales before choosing whether to buy himself. A sequential scheme maximizes the amount of information available to consumers, allowing success to breed success. Failure can also breed failure, but this is made less likely by consumers’ desire to influence one another’s behavior. We show that when consumers differ in the weight they place on the network externality, the firm would like to serve consumers with lower weights first. Our results suggests that a firm launching a new product should first target independent-minded consumers who can serve as opinion leaders for those who follow.
