Dorjiald R. Lichtenstein,.Richard G. Netemeyer, & Scot Burton Distinguishing Coupon Proneness From Value Consciousness: An Acquisition-Transaction Utility Theory Perspective Previous research on coupon proneness has measured the construct only in behavioral terms (i.e., consumers who are more responsive to coupon promotions are coupon prone). On the basis of the study premise that at least one other psychological construct, value consciousness, underlies the behavior of redeeming coupons, the authors argue that coupon proneness should be conceptualized and measured at a psychological level and treated as one construct that affects coupon-responsive behavior rather than as isomorphic with the behavior. They offer conceptual definitions of both coupon proneness and value consciousness and make a theoretical distinction based on acquisition-transaction utility theory. Eight hypotheses that reflect theoretical differences between the two constructs are proposed and tested. Results support the study premise that coupon-responsive behavior is a manifestation of both value consciousness and coupon proneness. C OUPONS give consumers opportunities to obtain promoted products at reduced prices. Because these reduced prices are in the form of a coupon, individuals who respond to coupon offers have been referred to as "coupon prone" consumers or, more generally, "deal prone" consumers. Most research involving deal proneness has measured the construct in behavioral terms; consumers who act on deals (e.g., coupons) are more deal prone (e.g., Blattberg et al. 1978; Dodson, Tybout, and Stemthal 1978; Hackleman and Duker 1980; Henderson 1985; Massy and Frank 1965; Montgomery 1971; Narasimham 1984; Schiffman and Neiverth 1973; Webster 1965). A major premise of our research is that for some consumers, the conceptually related but distinct psychological construct of Donald R.

"•rollowing the conceptualization of Monroe and Petroshius (1981), we can define value as the ratio of quality to price. As coupon offers involve a lesser outlay of money, some consumers may redeem coupons because of the increase in value rather than because of a proneness to respond due to the reduced price being offered in coupon form. Consequently, when the construct of coupon proneness is measured strictly in behavioral terms, coupon proneness is confounded with the correlated construct of value consciousness. Hence, we argue that coupon proneness should not be conceptualized as isomorphic with coupon-responsiveness behavior, but rather should be conceptualized and measured at a psychological level as only one construct that affects the behavior of redeeming coupons. We employ acquisition-transaction utility theory (Thaler 1983) as a paradigm for investigating the relationship between coupon proneness and one Journal of Marketing Vol. 54 (July 1990), 54-67 other psychological construct, value consciousness, which is also hypothesized to underlie coupon-redemption behavior. Conceptual Background Two serious problems in dealing research are the lack of a conceptual definition of deal proneness and the fact that conclusions are based solely on empirical data analysis with no prior theoretical framework (Raju and Hastek 1980). As a consequence, explanations of consumer response to deals at the individual level usually are not provided, and hence little is known of the psychological processes underlying dealing behavior. Similarly, some researchers have noted that little research has examined dealing behavior from the consumer's viewpoint in an effort to understand the behavior for its own sake (Price, Feick, and GuskeyFederouch 1988; Shimp and Kavas 1984). We contend that coupon-redemption behavior is a function of value consciousness as well as coupon proneness. Thus, when the construct of coupon proneness is grounded in behavioral terms of "does or does not act on a given coupon offer," it is confounded with the correlated construct of value consciousness. Previous research supports this position. For example, some researchers have argued that a price reduction in coupon form may produce an increase in consumer response beyond that expected from an equivalent lower price (Raju and Hastek 1980; Schindler and Rothaus 1985). Consistent with this contention is Cotton and Babb's (1978) finding that a price discount in coupon form produced a significantly larger increase in sales than an equivalent lower price. Nevertheless, quantity demanded was higher at lower prices, as would be expected by the negative relationship between price and quantity demanded. This observation suggests that classifying all individuals who respond more heavily to coupons as coupon prone is an overstatement. That is, many of these coupon-redeeming individuals may be more "value prone" than "coupon prone," and thus would have responded similarly had the product been offered at the equivalent lower price. Because coupon proneness and value consciousness have in common a focus on paying lower prices, these constructs have many similar implications for marketplace responses. However, because there are characteristics that these two constructs do not share, they also carry some different implications for marketplace responses. The primary objective of our article is to discriminate between the constructs "value consciousness" and "coupon proneness" on the basis of acquisition-transaction utility theory (Thaler 1985) and to demonstrate the differential relationships of these two constructs with cognitive and behavioral constructs. We begin by offering conceptual definitions of coupon proneness and value consciousness. Then we offer a theoretical distinction between the two constructs based on utility theory concepts (Thaler 1985). A hypothesis for our major premise (i.e., coupon responsive behavior is a manifestation of value consciousness as well as coupon proneness) is proposed and tested via covariance analyses examining the effect of value consciousness of self-reported coupon redemption behavior (controlling for the effects of coupon proneness). Next, seven additional hypotheses on the relationship between value consciousness, coupon proneness, and various related cognitive and behavioral marketplace responses are proposed and tested. Finally, we discuss results and limitations along with implications for marketers and future research needs. Coupon Proneness Because coupon proneness cSan be conceptualized as one dimension of deal proneness, previous characterizations of deal proneness appear to be an appropriate starting point for developing a conceptual definition of coupon proneness. Prior research suggests that deal proneness can be defined in terms of a general proneness to respond to promotions predominantly because they are in deal form. For example, Hackleman and Duker (1980) suggest that a deal prone consumer is one who is more likely to find a deal "impossible to refuse." Thaler (1983) suggests that deal prone individuals are likely to be those who purchase something because it is a deal, only to have it lie around the house and never be used. Henderson (1988) suggests that consumers who operate on the behavioral mechanism of coupon primacy have a predominant "commitment to a coupon" that prevents attention to factors such as lowest price or best value for the money. As a result, many of these consumers may be implicitly more likely to make their purchase decisions on which brand to buy outside the store at the time they clip a coupon. Similarly, Zeithaml (1988) found a segment of consumers who define value in terms of "sales," "specials," and "ability to use coupons."' She found that many of these consumers use coupons as extrinsic signals of good deals without actually comparing the reduced price of the couponed brand with the prices 'Zeithaml's use of the term "value" is not isomorphic with the term "value consciousness" used here in that it has a different "systematic meaning" (cf. Peter 1981). Zeithaml uses the term "value" in a very broad sense to reflect the many different things consumers "value" (place importance on) in a purchase transaction, which include the product as well as such factors as the shopping experience, interpersonal contact, and the ability to use coupons. As noted in the introduction, the term "value consciousness" has a more narrow meaning consistent with the definition of Monroe and Petroshius (1981) and pertains to a specific concern for "value" received (defined in terms of need-satisfying properties of the product) for price paid. This definition is also consistent with value as defined in acquisition-transaction utility theory (Thaler 1985). Distinguishing Coupon Proneness From Value Consciousness / 5 5 of other hrands. Operating in such a manner suggests that these consumers may rely "mindlessly" on coupons as indicators of good deals (Henderson 1988; Zeithaml 1988). These characterizations suggest that deal prone consumers may perceive a deal as an end in itself as well as a means to an end. Therefore, deal proneness is defined as an increased propensity to respond to a purchase offer hecause the form of the purchase offer positively affects purchase evaluations. Similarly, coupon proneness can he defined as an increased propensity to respond to a purchase offer hecause the coupon form of the purchase offer positively affects purchase evaluations. Value Consciousness Perceived value has heen defined as "the consumer's overall assessment of the utility of a product hased on what is received and what is given" (Zeithaml 1988, p. 14). On the assumption that for most people price and quality are the most salient "give and get" components, we define value consciousness as a concem for paying low prices, suhject to some quality constraint.^ This definition is consistent with the definition of Monroe and Petroshius (1981; i.e., the ratio of quality to price), the findings of Zeithaml (1988) on the meaning of value used hy many consumers (i.e., "the quality I get for the price I pay"), and several other definitions of value that appear in the literature (cf Zeithaml 1988). A Theoretical Distinction Based on Utility Theory Thaler (1985) postulates two types of utility associated with consumer purchases (see equation 1). The first is acquisition utility, which'represents the economic gain or loss from a purchase transaction. Specifically, acquisition utility is equal to the utility derived from the purchased good minus the price paid for the good (see equation 2). The second type of utility—transaction utility—represents the pleasure (or displeasure) associated with the financial terms of the deal per se and is equal to the intemal reference price (i.e., the mentally stored price against which other prices are judged; Rosch 1975) minus the purchase price. The theoretical importance of the role of the ^The "subject to some quality constraint" part of the definition (rather than a strict ratio of quality to price) is used to suggest that though a consumer recognizes one brand as offering the highest ratio of quality to price, it may not necessarily be the best value for the particular consumer. The quality of the product may exceed the consumer's specific quality requirements. Therefore the highest value for the particular consumer is viewed as the lowest priced product that meets his or her speciflc quality requirements. 56 / Journal of Marketing, July 1990 intemal reference price in affecting purchase evaluations cannot he overstated. That is, because purchase evaluations are hypothesized to he related positively to the amount hy which the intemal reference price exceeds the purchase price, anything that affects the intemal reference price necessarily affects purchase evaluations (Lichtenstein and Bearden 1989; Thaler 1985; Winer 1986). Total Utility = Acquisition Utility + Transaction Utility (1) Total Utility = (Utility of Purchased Good - Purchase Price) (2) + (Intemal Reference Price — Purchase Price) Equation 2 indicates that, with purchase price held constant, acquisition utility is a function of the utility of the purchased good, whereas transaction utility is a function of the intemal reference price. The utility of the purchased good is determined hy the inherent need-satisfying properties of the product (Thaler 1983). The hasis of the intemal reference price is less clear. The intemal reference price may conespond to some average price of similar products (Emery 1970), the price of the most frequently purchased hrand (Gahor and Granger 1961), the price most frequently charged (Olander 1970), the price last paid, the huyer's notion of a fair price (Monroe 1973), the most recently ohserved price (Winer 1986), the lowest market price (Lichtenstein and Bearden 1989), or other possihle hases (cf. Klein and Oglethorpe 1987). Zeithaml and Graham (1983) suggest that though the mechanisms by which consumers form intemal reference prices are largely unknown, most research is based on the assumption that intemal reference prices are derived from (1) experience with the product or (2) readily accessihle information from the environment. With purchase price held constant, if the internal reference price is hased largely on the perceived utility of the product, transaction utility will he affected by acquisition utility (see equations 1 and 2). In this case, coupons provide increases in transaction utility (and, hence, "good deals") otily if they are used for hrands that offer higher levels of perceived needsatisfying ability. In contrast, if the intemal reference price is hased primarily on extemal price information (e.g., normal prices charged), transaction utility is less dependent on acquisition utility. In this case, the use of a coupon represents a "good deal" (via transaction utility) for any hrand because it increases the amount hy which the (extemal price-based) intemal reference price exceeds the purchase price. A hasic premise underlying our research is that individuals whose value perceptions are largely affected hy the inherent need-satisfying ahility of the product (acquisition utility) are more likely to he value con- scious than coupon prone. Conversely, individuals whose value perceptions are more dependent on transaction utility (and less dependent on acquisition utility) are more likely to be coupon prone. The basis for this premise is the relationship between the conceptual definitions of value consciousness and coupon proneness and their differential relationships with the two types of utility. Because the coupon form of the price deal (i.e., a coupon vs. a lower offering price) affects the internal reference price (and hence transaction utility), but does not affect the inherent need-satisfying ability of the product (and hence acquisition utility), the value perceptions of coupon prone consumers are more likely to be affected by transaction utility than are the value perceptions of value conscious consumers. Conversely, because value consciousness (i.e., a low price subject to some quality constraint) explicitly addresses the inherent need-satisfying properties of the product, and thus is more closely allied with acquisition utility, value perceptions of value conscious consumers are more likely to be affected by this type of utility than are value perceptions of coupon prone consumers. Consistent with this perspective, eight hypotheses pertaining to differential effects of value consciousness and coupon proneness on consequences of interest are offered. Hypotheses Differential Relationship With CouponResponsive Behavior We contend that coupon-responsive behavior is a manifestation of value consciousness as well as coupon proneness. If this contention is valid, value consciousness should explain significant variation in coupon-responsive behavior after one accounts for the variation in coupon-responsive behavior explained by coupon proneness. Hence: H,: Value consciousness explains a significant amount of variation in coupon redemption behavior after one accounts for the variation in coupon redemption behavior explained by coupon proneness. To assess further the validity of the proposed acquisition-transaction-utility-based delineation between value consciousness and coupon proneness, we offer seven additional hypotheses on cognitive and behavioral consequences of interest. The rationale for these hypotheses is drawn directly from the preceding discussion on acquisition and transaction utility theory. Several of the hypotheses pertain to constructs central to the deal proneness literature (e.g., brand loyalty, deal retraction), but all hypotheses on differences between coupon proneness and value consciousness have theoretical grounding in Thaler's (1985) utility theory.^ Differential Relationships With Cognitive Constructs H2a and H2b propose different relationships between value consciousness and coupon proneness and enduring and situational involvement. Bloch and Richins (1983) have distinguished between enduring involvement and situational involvement. Enduring involvement is ongoing and more likely to be related to the product class, whereas situational involvement is temporary and more likely to be due to a particular prod, uct-related situation. Value conscious consumers are more concerned about acquisition utility (the inherent need-satisfying properties of the product).'* This focus implies that value conscious consumers are concerned about the product's value in use over time, which is a stable characteristic of the product. Thus, value conscious individuals are likely to have greater enduring involvement with the product. Conversely, coupon prone individuals are viewed as having more involvement in any purchase situation or specific transaction, which includes acting on a coupon. This greater focus on transaction utility should result in greater situational involvement for coupon prone consumers. H2a: The correlation between value consciousness and enduring involvement with purchased products is greater (more positive) than the correlation between coupon proneness and enduring involvement with purchased products. H2b: The correlation between coupon proneness and situational involvement is greater (more positive) than the correlation between value consciousness and situational involvement. H3a and H3b pertain to consumers' price and product knowledge. For at least two reasons, value conscious individuals should have more accurate price and product knowledge for purchased goods than coupon prone individuals. First, because coupon prone con^These additional hypotheses (i.e., Hj-Hg) are not considered to be exhaustive of all possible acquisition- and transaction-utility-based differences between the value consciousness and coupon proneness constructs. Rather, these hypotheses are offered to illustrate the conceptual differences between these two constructs, and as such are assumed to represent only a subset of those that might have been offered. 'In the rationale for the hypotheses, consumers may seem to be positioned as either "value conscious" or "coupon prone." It is not our intent to imply a mutually exclusive relationship between the two. Rather, we feel that a given consumer may have high degrees of both value consciousness and coupon proneness, low degrees of both value consciousness and coupon proneness, or a high degree of one but not the other. Hypotheses are stated and tested in a manner consistent with this view. In the discussion of hypotheses, language suggesting that consumers are either coupon prone or value conscious is used to simplify the rationale for hypothesized relationships. Distinguishing Coupon Proneness From Value Consciousness / 5 7 sumers are influenced more by transaction utility, they are expected to purchase a wider variety of brands than value conscious individuals. If fewer brands are purchased by value conscious consumers, greater purchase repetition may result in more accurate price and product knowledge for products they purchase. Second, the (predicted) higher level of enduring involvement with the product (H2a) for value conscious consumers also suggests that they may be more knowledgeable than coupon prone consumers about the products they purchase. , H3a: The correlation between value consciousness and product knowledge of purchased products is greater (more positive) than the correlation between coupon proneness and product knowledge of purchased products. H31,: The correlation between value consciousness and price knowledge of purchased products is greater (more positive) than the correlation between coupon proneness and price knowledge of purchased products. Tabuer (1972) notes that an implicit, ego-centered purchasing competition appears to occur between buyers (i.e., a concern for paying lower prices for products than other consumers pay). H4 pertains to this shopping competitiveness and again is based on the premise that value conscious consumers are more concerned with acquisition utility than are coupon prone consumers, and coupon prone consumers are more concerned with transaction utility than are value conscious consumers. Based on Thaler's (1985) conceptualization, acquisition utility is a function of value in use whereas transaction utility is a function of the internal reference price. Because what other consumers pay is expected to affect the internal reference price but not value-in-use perceptions, coupon proneness should be correlated more highly with shopping competitiveness than is value consciousness. That is, a consumer may find out that he or she paid a higher price than others paid, but this knowledge does not affect the inherent need-satisfying (value-in-use) properties of the product in relation to the price paid (i.e., acquisition utility). However, finding out that someone paid less serves to lower the internal reference price, which negatively affects transaction utility. H4: The correlation between coupon proneness and shopping competitiveness is greater (more positive) than the correlation between value consciousness and shopping competitiveness. The rationale for H5, concerning consumer evaluations associated with deal retraction, is again linked to utility theory. Rothschild and Gaidis (1981) state that primary reinforcers (the product) have intrinsic utility whereas secondary reinforcers (e.g., coupons) have no such utility. Our contention is that this primary-secondary ordering is more applicable for value 58 / Journal of Marketing, July 1990 conscious than for coupon prone individuals. In comparison with value conscious individuals, coupon prone individuals are more likely to view coupons as primary reinforcers whereas the product itself is more likely to take on the role of a secondary reinforcer. In terms of utility, value conscious consumers are relatively more likely than coupon prone consumers to perceive acquisition utility as primary and transaction utility as secondary. Coupon prone consumers are relatively more likely than value conscious consumers to perceive transaction utility as primary and acquisition utility as secondary. Sawyer and Dickson (1984, p. 14) state that "care must be taken so that eventually the product is the reinforcing stimulus rather than the sales promotion," indicating that the criterion of primary versus secondary reinforcement is not fixed, but rather depends on the perceptions of the consumer. Hence, we posit that the product is more likely to be the primary stimulus for the value conscious consumer and the coupon is more likely to be the primary stimulus for the coupon prone consumer. Because the coupon is more likely to be the primary reason for the purchase for coupon prone consumers, deal retraction should have a more negative impact on those consumers. H5: When a deal is retracted, the correlation between coupon proneness and unfavorable purchase evaluations is greater (more positive) than the correlation between value consciousness and unfavorable purchase evaluations. Acquisition and transaction utility also seemingly have implications for the marginal utility of additional purchase quantities. We propose that diminishing marginal utility of a commodity should be experienced earlier by value conscious individuals because their utility is derived primarily from use situations, and one can use only so much of any commodity. Because transaction utility is more important for the coupon prone consumer than for the value conscious consumer, and the number of transactions a consumer can make is limited only by his or her budget, marginal utility should decline more slowly for coupon prone than for value conscious consumers. Hg: The correlation between coupon proneness and marginal utility of additional purchase quantities is greater (more positive) than the correlation between value consciousness and marginal utility of additional purchase quantities. Differential Relationships With Behavioral Constructs Much of the previous research on dealing behavior has addressed the relationship between purchases on deed and brand loyalty. As would be expected, the relationship between responding to deals and repeat purchases of the same brand usually has been negative (cf. Schiffman and Neiverth 1973). When consumers who redeem coupons are differentiated as being value conscious or coupon prone, coupon prone individuals should exhibit less brand loyalty than value conscious individuals. These hypothesized relationships are again based on the differences between acquisition and transaction utility. Acquisition utility should covary more strongly with the brand than transaction utility, whereas transaction utility should covary to a greater degree with the coupon. That is, both terms associated with transaction utility (see equation 2) are affected by a coupon (i.e., a coupon serves to lower the purchase price and to reinforce perceptions of a higher normal price, thus leading to a higher internal reference price). In contrast, only the purchase price term associated with acquisition utility is affected by a coupon; need-satisfying ability is brand specific and is not affected by a coupon. Because of the greater impact of deals on transaction utility, coupon proneness should be related more negatively to brand loyalty. H7: The correlation between coupon proneness and brand loyalty is less (more negative) than the correlation between value consciousness and brand loyalty. Finally, we hypothesize that differences in the importance of acquisition and transaction utility between value conscious and coupon prone consumers also may affect aspects of consumer information search. For example, because coupon prone consumers' value perceptions are seen as infiuenced more by transaction than by acquisition utility, and because transaction utility is tied exclusively to price information (i.e., internal reference price and purchase price), coupon prone consumers are less likely to perceive benefit from searching for quality or "value for the money" information about brand altematives. Value conscious consumers are more likely to consider "value in use" in addition to purchase price and thus are more likely to search for "value for the money" information. Consumer Reports magazine has been widely recognized as a source of "value for the money" information (cf. Curry and Faulds 1986). Consequently, we hypothesize that both the behavior of reading Consumer Reports and the perception of the value of the information provided by Consumer Reports are correlated more positively with value consciousness than with coupon proneness. Hgj: The correlation between value consciousness and readership of Consumer Reports is greater (more positive) than the correlation between coupon proneness and readership of Consumer Reports. Hgb: The correlation between value consciousness and the perception of usefulness of information provided by Consumer Reports is greater (more positive) than the correlation between coupon proneness and the perception of usefulness of information provided by Consumer Reports. Method To test the hypotheses, we developed measures of coupon proneness (CP) and value consciousness (VC) using the scale development procedures recommended by Churchill (1979). For constructs hypothesized to be differentially related to CP and VC, we drew measures from the literature and also used the following pretest procedures to generate and purify items. Pretest Consistent with the procedures of Churchill (1979), a pool of 66 items was generated to refiect the conceptual definitions of the value conscious and coupon prone constructs (33 items each). To assess the face validity of the items, a judgment sample of three marketing faculty members and two marketing PhD students were given the conceptual definitions and asked to categorize each statement as VC, CP, or not applicable. An a priori item-retention decision rule was used whereby only items for which at least four of five judges agreed on the category were retained (cf. Bearden, Netemeyer, and Teel 1989). This decision rule resulted in the retention of 43 items (18 for VC and 25 for CP). In a procedure similar to those followed in the marketing literature (e.g., Zaichkowsky 1985), the face validity of this reduced set of items next was assessed by five additional judges (again, three marketing faculty members and two maiketing PhD students). These judges were asked to rate each item as clearly representative, somewhat representative, or not representative of the constructs. Only items that were classified as clearly or somewhat representative by at least four of five judges were retained, resulting in 15 and 25 items for VC! and CP, respectively. These remaining items were interspersed randomly throughout a questionnaire that was administered to a pretest sample of 263 graduate and undergraduate business students. Two sets of analyses were performed on the data. In the first, the item-to-total correlations were examined. Only items with corrected item-to-total correlations greater than or equal to .40 were retained (Saxe and Weitz 1982). This procedure resulted in the retention of seven items for VC and eight items for CP. The items representing the VC and CP constructs are listed in Appendix A.' 'In an initial version of the manuscript, the CP construct was labeled as deal proneness rather than coupon proneness. However, scale puHHcation procedures resulted in a final scale consisting primarily of coupon-related items. Therefore, on the basis of reviewer comments, we defined the construct more narrowly as coupon proneness and deleted four items on grounds of content validity (i.e., they referred to rebates, specials, etc., in addition to coupons). Distinguishing Coupon Proneness From Value Consciousness / 5 9 In the second set of analyses on these data, we examined the reliability and structure of the remaining items by using confirmatory factor analysis and internal consistency reliability. To determine the dimensionality of the measures, we compared null and one-factor models with the hypothesized correlated twofactor structure using LISREL VI (Joreskog and Sorbom 1983). The chi square values were 1813.60 (d.f. = 104, p < .01) for the null model, 829.65 (d.f. = 90, p < .01) for the one-factor model, and 440.33 (d.f. = 89, p < .01) for the hypothesized correlated twofactor structure. Though significant, the correlated twofactor structure offered a substantial improvement in fit over both the one-factor model (x^ difference = 389.32, d.f. = 1, p < .01) and the null model (x^ difference = 1373.27, d.f. = 15, p < .01), thus offering support for the dimensionality and discriminant validity of the VC and CP measures (Anderson and Gerbing 1988; Bagozzi and Phillips 1982). In addition, all indicator t-values associated with the correlated two-factor model were significant at the .01 level and the internal consistency estimates (i.e., construct reliability; Fomell and Larcker 1981) for the sevenitem VC and eight-item CP measures were .80 and .88, respectively. To further establish the discriminant validity between VC and CP, we conducted several additional tests. First, the discriminant validity between two factors is supported if the phi correlation between the factors ((})) is less than one (Bagozzi 1980). For the VC and CP measures, this condition was satisfied (<}) = .36, S.E. = .04). A complementary assessment of discriminant validity involves assessment of whether the confidence interval (plus or minus two standard errors) around the maximum likelihood phi correlation includes a value of 1.0. If not, discriminant validity is supported (Anderson and Gerbing 1988). This condition was also satisfied (.28 < <|) < .44). Last, the dimensionality and discriminant validity between two measures can be examined by comparing the variance explained in the two constructs with the square of the correlation between the two constructs. If the variance explained estimates are greater than the square of the correlation between the constructs, discriminant validity is supported. The variance explained in VC was .37 and the variance explained in DP was .48. Both of these estimates were greater than <t>^ which equaled .13. In sum, all three tests support the discriminant validity of the VC and CP measures. Measures of cognitive and behavioral constructs hypothesized to be differentially related to VC and CP also were pretested in this administration. We assessed reliability estimates for these measures by using coefficient alpha, and modified the scale items where necessary. 60 / Journal of Marketing, July 1990 Maiti Study A convenience sample of 350 nonstudent adults from a medium-size SMSA was employed to test the hypothesized relationships. Forty-three percent of the respondents were men and 69% were married. The average respondent had some college education and 40% were college graduates. The median age and household income categories were 35 to 44 years and $30,000 to $39,999, respectively. With data from this study, we again used confirmatory factor analysis and internal consistency estimates to evaluate the structure and reliability of the VC and CP measures. The chi square values associated with a null and one-factor solution were 2974.12 (d.f. = 104, p < .01) and 1124.11 (d.f. = 90, p < .01), respectively. For the hypothesized correlated twofactor structure, the chi square value was 559.55 (d.f. = 89, p < .01). The difference in chi square values between the two-factor and one-factor structure was significant (564.56, d.f. = 1, p < .01), as was the difference between the two-factor structure and the null model (2414.57, d.f. = 15, p < .01). These results support the modeling of a two-factor structure. Consistent with results of the pretest, all t-value indicators for the two-factor structure were significant (p < .01) and the construct reliability estimates were .80 and .88 for VC and CP, respectively. Item-to-total correlations were above .40 for all items across both construct measures. The correlation between the VC and CP measures was significantly less than one (<t> = .24, S.E. = .04) and the confidence interval around phi did not include a value of one (.16 < <|) < .32), supporting the discriminant validity of the two constructs. In addition, the variance-extracted estimates for the VC and CP measures were .37 and .48, respectively, and were both greater than <|)^ of .058. In sum, despite the differences in subject pools (i.e., students and nonstudent consumers), these results mirror those of the pretest. Multi-item measures of the constructs hypothesized to be differentially related to VC and CP were gathered. Some of the measures were established scales used in previous research and others were constructed specifically for use in our study. All measures were assessed for face validity and reliability (coefficient alpha) in the pretest procedures described previously. Sample items for each of these measures are listed in Appendix B. For all of the constructs (i.e., VC, CP, and constructs hypothesized to be differently related to VC and CP), scales were coded/recoded so that higher scores refiect higher levels of the construct. Internal consistency estimates for the measures are reported in Table 2. In addition to these items, a general measure of coupon-redemption behavior, as well as provided responses ranging from 0 to 100%. Results of these analyses are reported in Table 1. For each of the five analyses, CP is a significant predictor (p < .01) of coupon redemption behavior. Also, in all five analyses, VC explains a significant amount of variation (p < .01) in coupon redemption behavior after we account for the variation explained by CP. These results provide consistent support for the major study premise in Hi that coupon redemption behavior is a manifestation of VC, as well as CP. four product-category-specific measures (toothpaste, laundry detergent, deodorant/antiperspirant, and shampoo), was employed. Results Test of Differential Relationship With CouponResponsive Behavior (H-,) Based on the contention that VC and CP are distinct constructs that both affect coupon-responsive behavior, the first hypothesis states that VC explains variation in coupon-redemption behavior after one accounts for variation explained by CP. To test this hypothesis, five hierarchical regression analyses were performed. In the first analysis, the dependent variable was the general self-report measure of coupon redemption behavior ("In the past month, on what percentage of your grocery shopping trips did you redeem coupons?" with seven response categories ranging from "less than 10% of my shopping trips" to " 9 1 100% of my grocery shopping trips"). On the first step the variance in coupon redemption behavior explained by CP was assessed. VC was entered on the second step, thus permitting a test of whether additional variance in coupon redemption behavior can be explained by VC. The remaining four hierarchical analyses were identical to the first except that the measures of coupon redemption behavior were product-category-specific (i.e., toothpaste, shampoo, laundry detergent, and deodorant). For example, the toothpaste coupon redemption behavior measure read, "Approximately what percent of the time do you use a coupon to purchase toothpaste?", for which subjects Test of Hypotheses on Cognitive Consequences All remaining hypotheses were tested by performing t-tests for the difference in correlations within the same sample (Cohen and Cohen 1975). Results on the differential relationships between cognitive (H2-H6) and behavioral constructs (Hv-Hg) are reported in Table 2. H2a predicts that the correlation between VC and enduring involvement with purchased products is more positive than the correlation between CP and enduring involvement with purchased products. The respective correlations are .26 and .12 (t = 2.27, p < .05), thus offering support for H2a. H2b, which predicts that the correlation between CP and situational involvement is more positive than the correlation between VC and situational involvement, also is supported (r = .60 and r = .40, respectively; t = 4.03, p < .01). The third hypothesis predicts a more positive correlation between VC and product knowledge and between VC and price knowledge than between CP and these two types of knowledge. The correlation between VC and product knowledge is .43, whereas the correlation between CP and product knowledge is -.01 TABLE 1 Effect of Value Consciousness on Coupon Redemption Behavior After Controlling for Coupon Proneness" Independent Variables" Coupon Proneness Dependent Variable General coupon redemption Coupon redemption. toothpaste Coupon redemption. shampoo Coupon redemption. laundry detergent Coupon redemption. deodorant/antiperspirant Value Consciousness Beta T-Value R^ Beta T-Value R^ .50 10.84"= 25.4 .16 3.41"= 27.8 .45 9.36"= 20.2 .22 4.52"= 24.7 .89 7.95"= 15.5 .17 3.42"= 18.3 .45 9.48"= 20.7 .22 4.60"= 25.3 .42 8.70-= 18.0 .15 2.98= 20.0 'Degrees of freedom for the reduced model (i.e., coupon prone only) are 1,345; degrees of freedom for the full model (i.e., both independent variables) are 2,344.

(t = 7.69, p < .01) and the correlations between VC and price knowledge and CP and price knowledge are .41 and .11, respectively (t = 5.13, p < .01). Thus, both H3a and H3b are supported. Only directional support is found for H4, which postulates a more positive correlation between CP and shopping competitiveness (.31) than between VC and shopping competitiveness (.24) (t = 1.17, n.s., H4 unsupported). However, the correlation between CP and unfavorable deal-retraction-related evaluations is greater than the correlation between VC and unfavorable deal-retraction-related evaluations (.29 and .15, respectively, t = 2.30, p < .05), offering support for H5. The sixth hypothesis pertains to the relationships of CP and VC with marginal utility. The correlation between CP and marginal utility of additional purchase quantities (.19) is significantly greater than the correlation between VC and marginal utility (.06), thus providing support for Hg (t = 2.09, p < .05). Tests of Hypotheses on Behavioral Consequences (Hj-Hg) The seventh hypothesis predicts a more negative correlation between CP and brand loyalty than between VC and brand loyalty. To test this hypothesis, we employed six different measures of brand loyalty: (1) a five-item brand loyalty scale (Jacoby and Chestnut 62 / Journal of Marketing, July 1990 1978), (2) a single-item general behavioral scale (Raj 1982), and (3) four single-item scales that assessed brand loyalty in four individual product categories (Raj 1982). Results pertaining to the relationships between brand loyalty and VC and CP are mixed. Only directional support is found for the multi-item scale (t = 1.13, n.s.); however, for the single-item general behavioral scale, the difference in correlations is statistically significant (t = 2.25, p < .05). For all four product-category-specific brand loyalty measures (i.e., toothpaste, detergent, deodorant, and shampoo), CP is more negatively correlated with brand loyalty than is VC, and for the detergent and deodorant measures, these differences are significant (t = 1.88, p < .05; t = 1.58, p < .10, respectively). These results offer general support for H7. Hga and Hgb pertain to the relationships between VC, CP, and Consumer Reports information. Hga postulates that Consumer Reportsreadershipwould be more highly correlated with VC than with CP. The correlations are .15 and .01, respectively (t = 2.22, p < .05), supporting H^. Hgb posits that VC would be more highly correlated than CP with perceptions of the usefulness of information provided by Consumer Reports. The respective correlations are .20 and — .02 (t = 3.52, p < .01), supporting Hgb. In sum, results pertaining to these eight hypotheses support the premise that CP and VC are distinct constructs with dif- ferent implications for coupon-responsive behavior and other consumer marketplace responses. Discussion Summary and Implications of Results Previous researeh on deal/coupon proneness has lacked a conceptual orientation and generally has employed a single-item behavioral measure. A variety of problems have resulted. Many researchers have not seemed to recognize that coupon redemption behavior may be motivated simply by the ratio of quality to purchase price and may have nothing to do with the coupon form of the offer, and hence that coupon redemption behavior is not equivalent to the psychological construct of CP. Such problems may suggest alternative interpretations of empirical results. For example, Blattberg et al. (1978) hypothesized that consumers who were the least deal prone did not own automobiles, lived in apartments, had less income, had one or more children under six years of age, and lived in households in which both spouses worked. If CP is conceptualized as a psychological state that is one antecedent of a consumer's response to a deal, such factors probably are more accurately described as moderators of the relationship between CP and coupon redemption behavior. That is, such factors do not lessen the individual's level of CP, but affect the strength of the relationship between CP and the likelihood of acting on that proneness. Confounding levels of abstraction (resulting from measuring the psychological construct of coupon/deal proneness in behavioral terms) and the use of singleitem measures of coupon/deal, proneness may have contributed to results that generally have been able to explain less than 10% of the variance in behavioral response to coupons/deals. The need to measure abstract constructs with multi-item measures is well documented. Single-item measures result in construct underrepresentation and/or contamination from other constructs (Churchill 1979). Such problems mirror those expressed by Jacoby and Chestnut (1978) in arguing that brand loyalty is a complex psychological construct that can never be accurately assessed or understood via pure behavioral measures. The lack of conceptual definition and the acceptance of a single-item behavioral measure probably also have served to retard the theoretical development of coupon proneness and, more generally, deal proneness. Shimp and Kavas (1984) note that though research has addressed the impact of deals on consumer choice, brand switching, product sales, and market share, surprisingly little research has examined behavioral response to deals at the individual level in an attempt to understand the behavior for its own sake. Similarly, Raju and Hastek (1980) have criticized deal proneness research generally for its lack of a theoret- ical orientation, and specifically for its lack of a conceptual definition of the construct. On a broader level, Zeithaml (1984) has criticized price perception research for its lack of a theoretical orientation in developing conceptual and operational definitions of constructs. We attempt to address these problems and criticisms. We demonstrate that CP and VC are distinct constructs that both underlie coupon redemption behavior and that these constructs are related differentially to other constructs of interest. By hypothesizing that CP and VC are two constructs that underlie coupon redemption behavior, the conceptual framework suggests that the more appropriate level of measurement of CP is the psychological, rather than the more common behavioral, level. In contrast to other researchers, we offer conceptual definitions of deal and coupon proneness, which to our knowledge are the first proposed in the literature. The definitions are consistent with the idea that purchase evaluations are enhanced by the form of the purchase offer per se, and are based on acquisition-transaction utility theory proposed by Thaler (1985). Drawing from this conceptual background, we developed a multi-item measure of CP and demonstrated it to be a psychometrically satisfactory measure of the construct. This construct also is shown to be distinct fi-om VC, and findings support the utility-theory-based proposition that coupon redemption behavior is a manifestation of both CP and VC. Future Research Findings indicate that further theoretical development of both coupon redemption behavior and CP is needed. Our measures of CP and VC explain between 18% and 28% of the variance in self-reported coupon redemption behavior. These results can be interpreted as encouraging, but they also indicate that much variance remains unexplained. We believe conceptual models specifying other psychological antecedents and moderators will lead to a greater understanding of coupon redemption behavior. Marketing managers will have a particular interest in future studies that further examine the relationship between CP, VC, and repurchase behavior. Researchers often note that a pitfall of consumer promotions is that once the promotion is removed, consumers do not repurchase. Similarly, Raj (1985) has argued that companies should assess the percentage of their market share that is brand loyal because such consumers provide stability by making the brand less vulnerable to competitive efforts. Both theoretical and empirical support from our study suggests that coupon promotions targeted at value conscious consumers who are not coupon prone may enhance the likelihood of repeat purchases for brands that offer high acquisition utility. Though the two constructs are correlated, when Distinguishing Coupon Proneness From Value Consciousness / 6 3 median splits were performed on each scale to create low and high groups and then cross-tabulated, 40% of the respondents were either low on VC and high on CP (20%) or high on VC and low on CP (20%). These results, along with the findings that support the hypothesized differential relationships, suggest that the correlation between the constructs is not so high as to reduce the potential importance of the differences between the constructs for marketing practitioners. That is, these results suggest that value conscious consumers who are not coupon prone may represent a sizable segment who are motivated to use coupons. If future research demonstrates that the repurchase probability of the high VC/low CP segment is greater than that of other consumers, this segment may prove a prime target for coupon promotions. The increased ability of marketers to target coupons at specific segments heightens the relevance of understanding the differences between coupon proneness, value consciousness, and coupon usage and repurchase behavior. Consumer scanner panels that track coupon redemptions and product purchases longitudinally offer a practical means for empirical testing. Field studies could be used to examine potential differences in the in-store behavior of deal prone and value conscious consumers. For example, heavy users of coupons have been hypothesized to engage in more out-of-store decision making (Bettman 1979; Henderson 1988). It would be interesting to observe in-store behavior (e.g., number of brands examined, time spent examining brands, information gathered about price, price per ounce) and to compare these data with coupxjn proneness and value consciousness measures across instances in which a coupon was and was not used for the purchase. Study Limitations One shortcoming of our study is the use of self-report measures of coupon redemption behavior. A few points about this limitation are noteworthy. First, self-report measures of coupon redemption behavior have been used in previous studies of coupon redemption (cf. Price, Feick, and Guskey-Federouch 1988; Shimp and Kavas 1984) and the correlation between self-report measures and observed coupon redemption behavior has been significant (Shimp and Kavas 1984). Second, we used one general measure and four productcategory-specific measures of coupon redemption behavior. Results are consistent in direction across all five measures, suggesting that these measures have a reasonable level of validity. Another limitation is related to the generalizability of the results to other forms of deals. Our measure pertains to only one dimension or type of deal-responsive behavior (i.e., coupons) and ignores other deal forms such as cents-off promotions and rebates. 64 / Journal of Marketing, July 1990 (This limitation also applies to much of the dealing literature, which often focuses on coupon usage.) Other forms of deal proneness and their relation to deal behavior should be examined. Reliability estimates are lower than anticipated for the deal retraction and shopping competitiveness constructs. However, the hypothesis about the former is supported in spite of its low reliability and the hypothesis about the latter is supported directionally. Hence, even stronger results might be expected with more reliable measures. Despite these limitations, our results have implications for marketing researchers. There is a strong need to recognize both VC and CP as psychological constructs that affect coupon redemption behavior. CP is shown to be distinct from the related construct, VC, which is shown to have an effect on coupon-redemption behavior beyond that of CP. Additional hypotheses based on utility theory further distinguish between CP and VC. We hope our results will stimulate further theoretical and empirical studies of antecedents and moderators of the relationships between CP, VC, and behavioral response to coupon promotions. Appendix A Items Comprising Coupon Proneness and Value Consciousness Scales All items are 7-point scales ranging from strongly agree to strongly disagree. All scale items were coded/recoded so that higher scores reflect higher levels of the construct. Coupon Proneness • Redeeming coupons makes me feel good. • I enjoy clipping coupons out of the newspapers. • When I use coupons, I feel that I am getting a good deal. • I enjoy using coupons, regardless of the amount I save by doing so. • I have favorite brands, but most of the time I buy the brand I have a coupon for. • I am more likely to buy brands for which I have a coupon. • Coupons have caused me to buy products I normally would not buy. • Beyond the money I save, redeeming coupons gives me a sense of joy. Value Consciousness • r am very concerned about low prices, but I am equally concerned about product quality. • When grocery shopping, I compare the prices of different brands to be sure I get the best value for the money. • When purchasing a product, I always try to maximize the quality I get for the money I spend. • When I buy products, I like to be sure that I am getting my money's worth. • I generally shop around for lower prices on products, but they still must meet certain quality requirements before I will buy them. • When I shop, I usually compare the "price per ounce" information for brands I normally buy. • I always check prices at the grocery store to be sure I get the best value for the money I spend. Shopping Competitiveness I am better at shopping for bargains than most people. Deal Retraction For some products, when the manufacturer stops offering coupons, I stop buying their products. Marginal Utility Even when I flnd a real good sale on a grocery item I am careful to buy only as much as I need. Appendix B Sample Items for Related Constructs Reference citations indicate the measures that were used in previous research. The other measures were developed specifically for our study. All measures used 7-place, strongly agree/strongly disagree scales, with the exception of the behavioral and product-specific brand loyalty measures and the Consumer Reports readership item. The response formats for the behavioral and product brand loyalty measures were: 1 = less than 10%, 2 = 10-20%, 3 = 21-40%, 5 = 61-80%, 6 = 81-90%, and 7 = 91-100%. The Consumer Reports readership item was operationalized in a 7-point never-always format. All scale items were coded/recoded so that higher scores reflect higher levels of the construct. Product Knowledge (Alba 1983; Brucks 1985; Gardner 1983) Brand Loyalty, Scale (Jacoby and Chestnut 1978; Raju 1980) I generally buy the same brands I have always bought. Brand Loyalty, Behavior (Raj 1982) In buying within a given product category, what percent of the time do you purchase the same brand? Brand Loyalty, Toothpaste (Raj 1982) When buying toothpaste, what percent of the time do you purchase the same brand? Brand Loyalty, Detergent (Raj 1982) When buying laundry detergent, what percent of the time do you purchase the same brand? Brand Loyalty, Deodorant (Raj 1982) When buying deodorant/antiperspirant, what percent of the time do you purchase the same brand? I have a lot of knowledge about how to select the best brand within a product class. Brand Loyalty, Shampoo (Raj 1982) When buying shampoo, what percent of the time do you purchase the same brand? Price Knowledge I know the prices I pay for the products I buy. REFERENCES Alba, Joseph W.
