Abstract This paper proposes a theory of media silence. The argument is that news organizations have the power to raise public concern and so affect the probability that there is ex-post verification of the true state of the world.

Abstract Following the ideas of the Tourism Area Life Cycle (TALC) theory, we propose a dynamic econometric model for tourism demand where the reputation effect (the effect of the lagged demand on the current tourism demand) is not constant, but dependent on congestion.
