The formation, evolution and replacement of price-quality relationships

Due to copyright restrictions, the access to the full text of this article is only available via subscription.This paper develops a theoretical framework to address how dynamic competitive interactions and customer preferences change the observed relationship between market price and quality, and it offers an empirical framework to study these phenomena. Our framework proposes that price–quality relationships in a market (the fair value line) evolve according to several processes. We define and discuss these processes, including: (1) line formation, (2) line evolution (comprised of line elevation, erosion, steepening, flattening, blurring, tightening, extension and contraction), and (3) line replacement, which involves redefining price or quality in the marketplace. Instead of assuming that prices are a stable function of observable product attributes only (the static equilibrium view), our framework generalizes to dynamic disequilibrium patterns observed in many industries. These patterns are empirically assessed and explained by customer, competitive, and technology forces analyzed in marketing and strategy literatures. For managers, we discuss how they should react to these processes or, even better, set them in motion. For marketing researchers, we specify several hypotheses on the processes’ antecedents and consequences, testable with readily available datasets
