This document presents a model to examine the strategic implications when retailers do not advertise prices. The model considers competition between a high-service retailer and a low-service retailer selling the same product. The model results in four possible structures: both retailers advertise prices, only the low-service retailer advertises price, only the high-service retailer advertises price, or neither retailer advertises price. The analysis finds that when a retailer does not advertise prices, competition is less intense but the retailer must charge a lower price. If the competing retailer advertises its price, it enjoys higher profits from the reduced competition. The document also discusses how the retailers' advertising decisions can conflict with what is optimal for the manufacturer.
