Abstract
This paper investigates the retailer's problem of positioning her private label against two national brands in terms of both product quality and product features. Using a demand function derived from consumer utility, we show that the private label's best positioning strategy depends on the nature of the national brands’ competition and its own quality. When the national brands are differentiated, a high quality private label should position closer to a stronger national brand, and a low quality private label should position closer to a weaker national brand. When the national brands are undifferentiated, the private label should differentiate from both national brands.
