Channels of Impact: User reviews when quality is dynamic and managers respond
We examine the effect of managerial response on consumer voice in a dynamic quality environment. We argue that, in this environment, the
consumer is motivated to write reviews not by the possibility that the re-
views will impact the decisions of other consumers, but that the reviews
will impact the actions of the management and the quality of the service.
