Using the uniform most powerful unbiased test, we observed the sales distribution of consumer electronics in Japan on a daily basis and report that it follows both a lognormal 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 the multiplicative term in the process displays a size-dependent… 
Estimating sales and sales market share from sales rank data for consumer appliances
Our motivation in this work is to find an adequate probability distribution to fit sales volumes of different appliances. This distribution allows for the translation of sales rank into sales volume.
An empirical comparison of sales time series for online and offline channels for commodities in China†
TLDR
An empirical comparison of sales time series for online and offline channels is made and it is found that most of the commodities' accumulative sales distributions can be fitted by power-law distributions.
A New Method for Measuring Tail Exponents of Firm Size Distributions
We propose a new method for estimating the power-law exponent of a firm size variable, such as annual sales. Our focus is on how to empirically identify a range in which a firm size variable follows

Predicted and verified deviations from Zipf's law in ecology of competing products.
TLDR
This work reports the first complete empirical test of Zipf's power-law distribution and its application, based on the empirical analysis of the dynamics of market shares in the product market, and finds that temporal variations and product differences of the observed power- law exponents can be fully captured by the theory with no adjustable parameters.

The Structure and Evolution of Buyer-Supplier Networks
TLDR
This paper investigates the structure and evolution of customer-supplier networks in Japan using a unique dataset that contains information on customer and supplier linkages for more than 500,000 incorporated non-financial firms for the five years from 2008 to 2012 to find the number of customer links is unequal across firms and firm growth rates tend to be more highly correlated the closer two firms are to each other in a customer-Supplier network.
Power laws in market capitalization during the dot-com and Shanghai bubble periods
The distributions of market capitalization across stocks listed in the NASDAQ and Shanghai stock exchanges have power law tails. The power law exponents associated with these distributions fluctuate

We analyze data sets containing the circulation of magazines and newspapers. We show that the cumulative distribution follows, in the range of large circulation, a power law behavior whose exponent

TLDR
A model of proportional growth to explain the distribution P(g)(g) of business-firm growth rates is introduced and it is found that the predictions of the model agree with empirical growth distributions and size-variance relationships.

Some Empirical Regularities in Market Shares
TLDR
The power law does better than an alternative model---namely, the exponential form---which has been studied in the literature but without having been compared to any alternative, and the findings have several managerial and research implications.
