摘要:

We study social learning with a ``viral'' feature: on a continuous time line, a group of consumers need to each make a decision of whether to adopt a product, where awareness of the product is transmitted from adopting consumers to new ones. A consumer bases her action on the time she becomes aware at as well as her private signal about product quality. We find a unique equilibrium depicting the product's life cycle: consumers start with herding on adoption given high initial belief and being sensitive to signals given low initial belief, then use mixed strategies which keep beliefs constant, followed by a period of relying on signals, and finally reject the product once and for all when beliefs fall below a threshold. For a strategic producer, viral social learning always emerges as a profit-maximizing choice. As consumers' prior belief differs, a viral product campaign has opposite effects on a producer's incentive for quality improvement.
