A Local Seller's App Channel Strategy Concerning Delivery

When a local seller launches an app channel, it can either deliver online orders itself or use a third party service. Given this background, an interesting problem is whether and how a local seller's channel strategy will be affected by these delivery options. To investigate this problem, we focus on a local seller facing these two delivery options. For each option, besides setting the online and offline prices, the seller also determines its delivery service coverage. Assuming that consumers are evenly located along an infinite Hotelling line, we propose a joint pricing and delivery distance decision model and derive the local seller's optimal decisions in two subcases, i.e., the seller is a price taker or a price setter. By analyzing and comparing the seller's optimal decisions in these situations, we find that (i) the local seller's channel strategy will be changed dramatically by the delivery option--- the seller will abandon the offline channel when it delivers itself; (ii) whether the seller is a price taker or price setter will also influence the seller's channel strategy; and (iii) unexpectedly, the highly developed just-in-time logistics is an important factor that helps the offline channel and app channel coexist in the Internet era.
