Abstract
Using the uniform powerful unbiased test, we observed the sales distribution of consumer electronics in Japan on a daily basis and report that it follows both a longnormal distribution and a power-law distribution and depends on the state of the market. We show that these switches occur quite often. The underlying sales dynamics found between both periods nicely matched a multiplicative process. However, even though multiplicative term in the process displays a size-dependent relationship when a steady longnormal distribution holds, it shows a size-independent relationship when the power-law distribution holds. This difference in the underlying dynamics is responsible for the difference in the two observed distributions
