Throughout the 1990s, interest in private label brands in the U.S. grocery industry has increased. Store brands currently account for slightly less than 15 percent of total dollar sales. In several European markets, private labels have been even more influential — for instance, in the United Kingdom, they accounted for 20 percent of sales in 1971 and 36 percent in 1994.1 With current demographics guaranteeing low growth in consumer spending on food and packaged goods far into the next century, private labels can be a formidable force in an already highly competitive grocery environment. The disposable diaper market suggests that, when not supported by a continuous stream of product innovations, categories can turn into commodities, rendering the retailer’s built-in distribution an even more valuable resource. Retailers get quick, cheap sales feedback that allows them to mimic what works for national brands while avoiding more costly mistakes. For example, being close to the customer has helped Starbuck’s turn a long-declining commodity into a value-added, distinctive store brand. Consequently, national manufacturers have become more alert to the threat of private labels, most retailers have taken steps to exploit the opportunity, and many smaller (and a few larger) manufacturers have begun to supply private label alternatives.
In this paper, I focus on the food retailing industry, where private labels are the dominant “brand” in about 20 percent of the more than 350 product categories that supermarkets carry.2 In the fresh produce and meat departments, which account for about 25 percent to 30 percent of total store sales, virtually all products are sold with the retailer’s name on a variable-weight package (like meat) or carry no brand name at all, so the retailer is the provider by default. Retailers make higher gross profit margins on private labels, usually about 20 percent to 30 percent on a percentage basis, which at times translates into higher profits on a dollar basis. Private label performance varies widely across product categories and items.3 For example, 65 percent of dollar sales in frozen green and wax beans accrues to the private label, whereas, in deodorants, private labels have only a 1.1 percent market share. Historically, private labels have had a greater presence in the frozen and refrigerated categories (20.4 percent and 15 percent, respectively, in 1989) than in health and beauty aids (4.4 percent).

9. I estimated category-level price elasticities for each store, separately for each product category, using Hoch et al.’s methodology. In addition, I computed private label market shares (in dollars) for each category. Detailed information describing the demographic composition (1990 census) and the competitive environment were available for the trading areas surrounding each of the store locations. See:

31. The sourcebook is billed as “the most comprehensive reference guide in the private label industry.” There are approximately 1,400 different manufacturers listed as private label suppliers in one or more of the product categories sold in grocery stores. Along with two experienced retail buyers, I identified all the firms listed that also manufactured national brands. See:
Product Label Product News, Supplier Source Book 5 (New York: Certified Publishers, 1991).
