The Relationship

The authors derive a theoretical relationship between the aggregate market share elasticity matrix and the aggregate brand switching matrix on the basis of a logit model of heterogeneous consumers choosing among competing brands in a product class. Aggregate cross-elasticities are shown to be proportional (through a single scaling constant) to their corresponding aggregate row-conditional brand switching probabilities. Aggregate own-elasticities are shown to be proportional (through the negative of the same scaling constant) to one minus their corresponding aggregate row-conditional repeat purchase probabilities. An empirical analysis conducted on household scanner panel data in the liquid laundry detergent category shows that the theoretical correspondence holds as a very good approximation. An illustrative use of the relationship in estimating aggregate (store-level) models of market share indicates that the relationship helps improve predictive validity in a holdout period.

Scanner Panel

The authors develop an approach to market segmentation based on consumer response to marketing variables in both brand choice and category purchase incidence. The approach reveals segmentation as well as the nature of choice and incidence response for each segment. Brand choice and purchase incidence decisions are modeled at the segment level with the disaggregate multinomial logit and nested logit models; segment sizes are estimated simultaneously with the choice and incidence probabilities. Households are assigned to segments by using their posterior probabilities of segment membership based on their purchase histories. The procedure thereby permits an analysis of the demographic, purchase behavior, and brand preference characteristics of each response segment. The authors illustrate their approach with scanner panel data on the liquid laundry detergent category and find segmentation in price and promotion sensitivity for both brand choice and category purchase incidence. The results suggest that many households that switch brands on the basis of price and promotion do not also accelerate their category purchases and that households that accelerate purchases do not necessarily switch brands.

Previously, toxicity of some synthetic detergents (including laundry detergents) to the plant seedlings of several species of terrestrial higher plants was discovered in research conducted at Moscow University by S.A.Ostroumov. A new example of toxicity of a laundry detergent to plant seedlings was found in this study. The synthetic detergent tested, namely the liquid laundry detergent (LLD) “Blue Moon”, which was manufactured by Blue Moon Group Co, Ltd (Guangzhou, China), produced noticeable phytotoxic effects on the plant seedlings of the terrestrial higher plant Lens culinaris. This detergent at the concentrations 0.5 % - 1% induced a pronounced decrease in the average root length of the seedlings of Lens culinaris. The concentration 5% was lethal to Lens culinaris.

The researchers of liquid detergent are most focused on detergency in the past, and the research on antibacterial activity of liquid detergent is rare. This research choose famous and common brands liquid laundry detergent in the market and studied their antimicrobial properties, test their antibacterial properties on the surface of the natural fiber fabric about Staphylococcus aureus (positive) and Escherichia coli (negative), analysis the antibacterial effect of the various brands, and the consumers have more reliable basis for purchase such goods. The antibacterial rate of liquid detergent against Galanz negative bacteria (E. coli) is generally higher, but the antibacterial rate against Galanz positive bacteria (S.aureus) is not good. The brand of Lan Yue Liang has excellent performance in this experiment, the antibacterial rate against E. coli and S.aureus reached to 96.25% and 95%.
