No pricing models exist that explicitly account for this dual effect of price. This article combines insights from behav- ioral research on the dual effect of price with a model of market segmentation and price discrimination among segments. The authors propose a method for market segmentation that is based on the degree to which con- sumers attend to the informational and sacrice effects of price and combine the segment-level parameter esti- mates with a model of price optimization. An empirical study using seven different product categories provides evidence in support of the robustness and relevance of the proposed approach. The results show that the dual effect-based approach captures consumers' price preference structures more precisely than a segmentation on the basis of the commonly measured total effect of price and thereby enables sellers to increase their prots. © 2011 Elsevier Inc.

In order to set prices optimally, marketers must account for consumers' (hetero- geneous) price reactions on the basis of economic and behavioral con- siderations, product costs, andif applicablecompetition (Estelami & Maxwell, 2003; Levy, Grewal, Kopalle, & Hess, 2004). Therefore, devel- oping an appropriate pricing strategy is both crucial and highly complex and has prompted an extensive stream of research on pricing principles, strategies, and tactics. To increase protability, marketers typically en- gage in some form of price discrimination, that is, they attempt to ex- ploit consumer heterogeneity through differential pricing strategies (Gijsbrechts, 1993). Most pricing models take as an essential input consumer response to changes in price. Two distinct effects, discussed as the dual role of price by previous research (e.g., Erickson & Johansson, 1985; Lichtenstein, Ridgway, & Netemeyer, 1993; Voelckner, 2008), drive this price re- sponse, namely, sacrice and informational effects of price. The sacrice effect, which stems from classic economic theory, refers to a consumer's evaluation of the amount of money that he or she must sacrice to satisfy his or her consumption needs. In this respect, price generates disutility, and higher prices decrease consumer surplus because consumers must pay more for the product. Previous research suggests two potential sources of the sacrice component of price: allocative effects and transac- tion utility. The former indicates the basic way of viewing price as a monetary constraint and varies, among others, with consumers' price consciousness and price mavenism (e.g., Erickson & Johansson, 1985; Lichtenstein et al., 1993). The latter represents the incremental utility as- sociated with a good dealwhich varies, among others, with consumers' value consciousness as well as sales and coupon proneness (Lichtenstein et al., 1993). Contrary to classic economic theory, however, consumers do not always buy the lowest priced product in a category, even when the products are otherwise similar. One behavioral explanation, supported by empirical evidence, is that consumers perceive prices as quality cues and assume a positive association between price and quality. Thus, higher prices may indicate higher quality and thereby increase consumers' per- ceived utility, which in turn results in a positive price elasticity of demand (Rao & Monroe, 1989). Other potential, but usually less signicant sources of the informational effect of price relate to feelings of prestige and status higher prices signal to other people and egocentric desires to make one- self a present (e.g., Lichtenstein et al., 1993; Voelckner, 2008). Despite strong empirical evidence that both sacrice and informa- tional effects drive consumer response to changes in price, pricing litera- ture has not discussed the implications of this dual effect of price for price discrimination and optimization decisions (Dixit, Whipple, Zinkhan, & Gailey, 2008; Monroe, 2003; Nagle & Hogan, 2006; Phlips, 1989). This gap in the literature may be because no (empirical) price optimization models exist that explicitly account for the dual effect of price (i.e., the Journal of Business Research 66 (2013) 480488 The authors thank the anonymous reviewers and the editor for their many helpful comments.
