【摘要】

 When product quality is unknown to consumers, a high-quality firm can signal its quality with a warranty, which entails lower repair costs for high-quality firms than for low-quality firms. This article constructs a theoretical model in which two competing firms may simultaneously send quality signals via warranties and prices. The authors find that a separating equilibrium always exists, and no pooling equilibrium survives the intuitive criterion. Additionally, signaling competition lengthens the warranty of a high-quality firm when it competes with a low-quality firm. However, signaling competition may shorten the warranty when it competes with another high-quality firm and the competition between them is not intense. This article then extends the signaling game to a duopoly market in which consumers are informed about the quality of one firm but are unaware of the quality of the other firm. The authors demonstrate that the high- quality firm provides a longer warranty when both firms’ qualities are unknown to consumers than when only its own quality is unknown. The hidden quality information of a low-quality firm benefits itself and harms its rival when the rival’s quality is high and also unknown to consumers.
