Abstract: | Comparative pricing practices are frequently used where actual product prices are accompanied by higher external reference prices. All types of stores, regular-price department stores as well as discount stores, use comparative price claims to frame price deals as attractive Marketing Science 4 (1985) 199]. In this paper, a quadratic model is specified for the impact of external reference price (ERP) on consumer price expectations. Based on the research on communication discrepancy and advertising claim discrepancy, which in turn draw on assimilation-contrast, attribution, and prospect theories, we hypothesize a quadratic effect of external reference prices on consumer price expectations. An interactive, computer-controlled experiment using multiple levels of ERP is used to estimate the proposed model. As hypothesized, support for an inverted U-shape relationship is found between consumers’ updated price expectations and the difference between ERP and initial price expectations. That is, as the difference between ERP and subjects’ initial price expectations increases, subjects’ updated price expectations increase to a point and then start to decrease. We find that the fit of the quadratic model specification for the effect of external reference price on price expectations is noticeably superior to that of linear, logarithmic, square root, and S-shaped specifications. Finally, we provide implications of our results for both retail managers and for regulatory authorities alike. |
