Price-quality relationship in pricing strategies for private labels

Purpose – This article aims to close some research gaps by differentiating between brand types and price tiers. Many consumers perceive high prices as signals of high quality, yet researchers tend to find only low average correlations between price and objective quality. Previous studies do not account for market shares and paid prices though. Design/methodology/approach – A German consumer panel with more than 30,000 households reveals market shares and paid prices. Combining these data with product test ratings, the authors evaluate price-quality relationships with Spearman’s rank correlation coefficients and distinguish food from non-food products, national brands and private labels and three price tiers. Findings – High price-quality correlations for national brands and non-food private labels indicate that a higher price signals greater product quality. For food private labels, negative correlation coefficients inhibit the use of price as a quality indicator. The price-quality relationship for food private labels implies strong competition among brand owners, based on the price and quality of their products. Originality/value – This article investigates price-quality correlations by accounting for paid prices and product market shares; it also reveals differences across food and non-food products, national brands and private labels and different price tiers against the background of competition strategies. By addressing when consumers use price as a quality indicator, it outlines important managerial implications for manufacturers, retailers and consumers.
