How Point-of-Sale Marketing Mix Impacts National Brand Purchase Shares Across Stores

-

Purchase shares of major national brands in consumer packaged goods industries vary substantially across stores, both between geographic markets and and across stores within markets. Furthermore, store-specific POS marketing mix factors (such as price, assortment share, feature, and display, and promotion intensity) show similar variation across stores. This suggests that POS marketing mix factors may be responsible for the observed dispersion in purchase shares. Shown below are examples from toilet paper brand: Charmin. We can clearly see that there are significant dispersion of purchase shares across stores. In addition, dispersion in purchase shares across stores are highly correlated with dispersion in assortment shares across stores.


From the large scale analyses, we find that on average, approximately 56% of variations in national brand purchase shares can be attributed to this five POS marketing mixes. Moreover, we also find that asymmetric POS marketing mix effectiveness (especially in price), which favors brands closer to their city-of-origins, is another underlying mechanism behind observed differences in purchase shares across geographic markets.

For more details, please refer to our POS paper (together with Prof. Raphael Thomadsen), which was accepted in Management Science (October, 2014). The link is shown below.

How The Influence of Multi-Tiered Private Label Brand Architecture Varies Across Retailers

Starting from Europe, many retailers now provide more than one quality tier (e.g. premium, standard, and economy) private labels in a specific category. To distinguish different quality tier products, retailers usually use different brand architecture. The examples below show that the actual branding architecture choice in the toilet paper private labels by three supermarket chains in Los Angeles.   Retailers have many choices in the private label branding architecture. As an example, retailer banners (e.g. Vons) can be combined with modifiers (e.g. premium, standard, and economy) in the "endorsed banner brand architecture." Retailers can choose not to use the retailer banner, but still use a common group brand (e.g. Home Life) with modifiers in the "group brand architecture". Finally, different names can be assigned for each quality tier in the "stand-alone brand architecture." Some combinations of these approaches are also possible. The natural
