Consider the problem of estimating the timing and magnitude of peak sales for a new consumer durable product which is infrequently purchased and initially has few replacement purchases (as compared to initial purchases) . In such a case typically the sales rate climbs to a peak over a period of years and then declines somewhat, with replacement purchases becoming a larger component of total sal...

OTC pharmaceutical sales explain 36% of the variance in the patient volume, and each standard deviation increase is associated with 4.7 more patient visits to the urgent care center (p<0.0001). Cross-correlation function analysis demonstr...

Recent papers have shown that, in contrast to ―the Long Tail‖ theory, movie sales remain concentrated in a small number of hits. These papers have argued that concentrated sales can be explained, in part, by heterogeneity in quality and increasing returns from social effects. Our research analyzes an additional explanation: how incomplete information may skew sales patterns. We use the movie br...

In this paper, I argue that both of these arguments are too simp...
