1、左數效果及消費者人格特質對於消費品價格認知的影響The effects of left-digit phenomenon and consumer characteristics on the perception of prices for consumption goods 龔昶元朝陽科技大學 企業管理系 副教授 李延熹朝陽科技大學 應用外語系 助理教授游曙吏朝陽科技大學 應用外語系 研究生AbstractIn order to increase their sales, companies endeavor to lure and stimulate consumers to purch

2、ase products through promotional activities, particularly monetary promotions. However, not all monetary promotions influence consumers to purchase products because differences in consumer characteristics, such as need for cognition (NFC), create different attitudes toward promotions. The question o

3、f whether consumers treat a nine-ending price to be cheaper than a zero-ending price has been discussed for long. Recent researches indicate that the left-digit effect has a significant impact on the revenue of firms. A number of researchers suggest that prices with left-digit effects increase the r

4、evenues of companies. Although monetary promotions such as left-digit effect and nine-ending prices influence consumers to purchase more, NFC may be one of the important elements that affect the purchase decision of consumers. NFC as one of the elements that affect the purchase decision of consumers

5、 has been robustly discussed; this study involves a further research of the question of whether NFC influences consumers who are affected by the left-digit effect. Consumers with high and low NFC exhibit different purchasing behaviors. In other words, different levels of NFC cause consumers to selec

6、t different products. Different considerations and attitudes toward consumption can be classified into high and low price cognition. This research investigates the viewpoint that different monetary promotions cause different perceptions of price because of different levels of NFC among consumers. Fo

7、r the purpose of this study, the questionnaire survey method is employed. Four hundred and fifty nine undergraduate university students, 135 males and 314 females in the age group of 17 to 25, from the Department of Business Administration participated in the survey.The results of the study provide

8、the foundation for the framework. We find that different levels of NFC affect the purchasing inclination of consumers. Not all left-digit effects encourage consumers to purchase products; left-digit effects influence consumers only if they have a low NFC. High-NFC consumers tend not to be affected b

9、y left-digit effect.Key words: Left-digit effect, NFC, promotionIntroductionIn order to increase their sales, different companies endeavor to stimulate and lure consumers to purchase their products through promotional activities, particularly monetary promotion.According to Kotler (2003), McCarthy c

10、lassified marketing tools into four groups, namely, product, price, place, and promotion. Promotion comprises sales promotion, advertising, sales force, public relations, and direct marketing. Many companies use promotional activities to stimulate consumers to purchase their products because consume

11、rs like to purchase products when promotional offers are provided by companies. However, different consumers may be influenced by different types of monetary promotions on account of different consumer characteristics, such as NFC; this difference may cause them to have different attitudes toward pr

12、omotional activities.Numerous researchers (Thomas and Morwitz, 2005; Coulter, 2001; Anderson and Simester, 2003) have researched the left-digit effect and nine-ending or odd-ending price. Researchers have found that consumers tend to purchase products if they perceive that the price is one cent lowe

13、r (e.g., $2.99 vs. $3.00). Furthermore, consumers read the digits of a price from left to right; therefore, they are likely to underestimate the price (Coulter, 2001). Although monetary promotion such as left-digit effect and nine-ending price affects consumers, thereby leading them to increase the

14、quantity of products purchased, NFC may be one of the important elements that affect the purchase decision of consumers. NFC is the tendency for people to engage in as well as enjoy thinking; furthermore, NFC focuses on the orientation of consumers toward motivation. Consumers with high or low NFC w

15、ill display different consumer behaviors.In other words, NFC influences consumers in their selection of products. Such factor is important to marketers because they affect the reactions of consumers to marketing strategies.A large number of companies adopt various measures in order to encourage cons

16、umers to purchase their products through monetary promotion; however, different types of monetary promotion might influence individual consumers differently. On the basis of the different elements under consideration and attitudes toward consumption, consumption can be classified into high and low p

17、rice cognitions. Therefore, this study classifies consumers into two different levels of price cognitions: high and low. Bearing this classification in mind, researching such market behavior produces the question of whether different kinds of monetary promotion affect the price cognition of consumer

18、s due to different levels of NFC. This research aids companies in understanding the manner in which the most suitable price policy can be decided upon for different types of consumers.Literature Review1. Left-digit EffectThis study aims to investigate whether consumers perceive prices with a lower l

19、eft digit to be a lot lower than prices with the same left digit (e.g., $230 and $199 vs. $240 and $200). The left-digit effect can be defined as follows: “The left-digit effect refers to the observation that using a nine-ending versus a zero-ending price, for example, $2.99 versus $3.00, changes th

20、e left-most digit” (Thomas and Morwitz, 2005).Monroe (2003) indicated that consumers do not notice small price changes. Anderson and Simester (2003) suggested that even though a nine-ending price changes the price of products by only one cent, the last digit of a price has a significant impact on ea

21、rning revenues.Stiving and Winer (1997) classified explanations associated with image effects and level effects. The image effect contains quality and price image. Quality-image effect causes consumers to perceive that products of prices with nine-ending are low-quality products. As for price image,

22、the image effect causes consumers to believe that the price of a product, store and so forth is based on right-hand digits. Therefore, image effects are concerned with firm behavior or intentions toward consumers. For example, the image effect of price causes consumers to regard nine-ending prices a

23、s a price discount.Employing round numbers as reference points enables companies to give a small amount back to consumers if companies adopt the policy of nine-ending prices, which are lower than round numbers (Kreul, 1982). For example, consumers may interpret $19 as a $1 discount from $20. On the

24、other hand, level effects cause the perception of prices among consumers to become distorted; thus, underestimating the price.It causes consumers to underestimate the fact that a nine-ending price is merely one unit lower than a zero-ending price.Consumers tend to round the price such as $3.99 to $3

25、.00 (Hollander, 1966; Schindler, 1984).To maximize profits, companies may select $3.99 rather than $3.33 or prices below $3.99. Moreover, limited memory capacity is also one of components to cause level effect because consumers would most likely memory the first digits of prices.Dehaene (1993) indic

26、ated that a number extends from left to right. Given the LR orientation (Coulter, 2001), left-most digits are the first numbers that consumers read, thereby making the left order of a price to be the first to be noticed. Presumably, if the order of numbers is reversed, LR orientation might disappear

27、. The left-digit effect refers to the observation that, for example, $799 vs. $800 is merely a change of the left-most digit rather than only the right-most digit. In other words, it is a change in the left digit rather than a one-dollar reduction in price. The perception that causes consumers to tr

28、ansform multi-digit numbers into mental magnitudes is the so-called analog model. Under specific conditions, the left-most digit exerts a relatively greater effect than the other digits because the left-most digit changes from 8 to 7, while the change in the right-most digit (zero-ending versus nine

29、-ending) are perceived as hardly significant. Therefore, some consumers perceive $799 as less expensive than $800. Multi-digit numbers are encoded as an analog representation (Dehaene, 1997; Monroe and Lee, 1999). As Dehaene (1997) indicated, individuals who assess the numbers with quantitative mean

30、ing usually tend to spontaneously map them onto an internal magnitude in the case of two multi-digit numbers. This study researches the orientation of consumers toward the left-most digit in order to investigate the price cognition of consumers. A number of researchers have shown the effects of left

31、-digit and last-digit prices (Thomas and Morwitz, 2005; Coulter, 2001; Anderson and Simester, 2003) with a focus on left-most and nine-ending prices. Therefore, this research aims to study consumers who enjoy investigating prices or securing greater benefits; in other words, some consumers are more

32、inclined toward purchasing products whose prices have a lower left digit, while some enjoy comparing different prices (with lower left digit and with the same left digit) in order to ensure that it is a good bargain based on their perception of the price. Rational consumers shop more frequently but

33、purchase products in smaller quantities when faced with higher price variability (Ho, Tang and Bell, 1998). Some researchers, such as Shen (2004), investigated consumers who perform actionrationally based on the theory of reasoned actionin order to understand the response of the consumers toward cou

34、pon promotion. Therefore, this study assumes that some consumers will display purchase behavior rationally toward the left-digit effect.2. Need For Cognition (NFC)NFC is the tendency for people to engage in as well as enjoy thinking. Cohen, Stotland and Wolfe (1955) proposed the concept of NFC and d

35、escribed that NFC is the need to structure pertinent situations in meaningful and integrated forms. In addition, Petty and Cacioppo (1986) demonstrated that NFC is not related to the traditional concept of intelligence.High-NFC consumers are more likely to possess a stronger intrinsic motivation to

36、engage in cognition and attempt to reduce any inherent errors.Therefore, when people feel motivated because of the interest, enjoyment, challenge, etc., of the work they indulge in, they are compelled by intrinsic motivation. On the contrary, low-NFC consumers do not enjoy thinking.High NFC individu

37、als are prone to use message content for judgment (Petty and Cacioppo, 1982) than low NFC individuals do (Haugtvedt, Petty and Cacioppo, 1992).The Need for Cognition scale ranges from low to high needs for cognition.As Liebermann and Flint-Goor (1996) stressed, high-NFC consumers tend not to be mani

38、pulated by different information regarding various products. In addition, advertisers manipulate the messages they convey to consumers by highlighting the unique characteristics of the products that may find favor with the consumers, thereby encouraging consumers to purchase their products. This is

39、the so-called peripheral effect of ELM (Elaboration Likelihood Model). Petty and Cacioppo (1983) believed that ELM will influence the attitudes and reactions of consumers toward advertisement. Therefore, NFC is a significant factor that may influence the purchase decision of consumers.Further, Petty

40、 and Cacioppo (1986) also indicated that NFC is cognition to the extent that individuals will engage in it on account of their intrinsic motivation. Based on this theory, numerous researches associated with NFC verify that high-NFC consumers possess stronger intrinsic motivation. They engage in cogn

41、ition in order to reduce the possibility of any errors they might commit when they are purchasing products. On the other hand, low-NFC consumers do not indulge in the evaluation process. Park and Hastak (1994) indicated that low-NFC consumers are reluctant when faced with cognitive endeavors and wou

42、ld rather avoid arduous discussions or deliberations with regard to certain aspects; therefore, tend to be easily influenced by others.3. Relationship between NFC and PromotionAccording to existing literature, the level of NFC influences consumer behavior. High-NFC consumers will retain product char

43、acteristics longer than low-NFC consumers. As Petty and Cacioppo (1983) suggested, NFC can be divided into the following two categories: the center type and the peripheral type. High-NFC consumers generally enjoy thinking and analyzing the price information of products when evaluating a promotional

44、activity; this is the so-called center type.However, low-NFC consumers are likely to be lured by promotional activities and only judge products based on simple clues and principles; this is the peripheral type. Pierre, Brain and Gilles (2000) found that monetary and non-monetary promotions provide c

45、onsumers either hedonic or utilitarian benefits. Hedonic benefits comprise value expression, entertainment, and exploration. On the other hand, utilitarian benefits include saving money, getting better quality products, and improving shopping convenience. In addition to hedonic and utilitarian value

46、s, NFC is one of the elements of consumer psychology. As Liebermann and Flint-Goor (1996) suggested, high-NFC consumers are not likely to be intimidated by the diverse information they are exposed to after reviewing a variety of products and prefer different types of promotions. Utilitarian benefits

47、 significantly effect high-NFC consumers (Kang, 2003).In other words, high-NFC consumers give more weight to utilitarian benefits; this implies that they consider the utility of products when purchasing new products (Kang, 2003).However, some consumers respond to promotional signals and disregard pr

48、ice differences. Low-NFC consumers respond to promotional signals without being mindful of price reductions, whereas high-NFC consumers respond to a promotional signal only when there is a substantive price reduction (Inman, McAlister and Hoyer, 1990). According to Inman, Peter, and Raghubir (1997),

49、 promotions with a restriction encourage low-NFC consumers to purchase products, whereas high-NFC consumers tend not to be affected by promotional restrictions or purchase limits, such as time limitation. NFC as a predictor of information processing among consumers has been robustly demonstrated in

50、numerous contexts. This study presents a further research into the relationship between NFC and promotion.Given the previous discussion, the hypothesis is:Compared with high-NFC consumers, low-NFC consumers will perceive prices with lower left digits (e.g., $920 vs. $890) to be lower than prices wit

51、h the same left digits (e.g., $990 vs. $950).MethodologyThe data are processed using SPSS statistical analysis. This study employs MANOVA and two-way ANOVA in order to investigate the left-digit effect and NFC for price cognition.The survey is employed and 500 questionnaires are sent to undergraduat

52、es. After expunging invalid questionnaires, 459 undergraduate university students, 138 males and 321 females in the age group of 17 to 25, from the Department of Business Administration participated in the survey conducted to test an independent variable (monetary promotion), a dependent variable (p

53、rice cognition), and moderator variables (NFC). The return rate of questionnaire is 91.8%.The students spent approximately 15 minutes to complete the questionnaire; each student received the requisite course credits for their participation in the survey. This study The 459 participants comprised 264

54、 high-NFC consumers and 195 low-NFC consumers, who filled out either the lower left digit or the same left digit questionnaires. Two hundred and twenty nine lower-left-digit questionnaires and 230 same-left-digit questionnaires were randomly distributed among the participants. Seventy-nine low-NFC p

55、articipants and 150 high-NFC participants filled out the lower-left-digit questionnaires. One hundred and sixteen low-NFC participants and 114 high-NFC participants filled out same-left-digit questionnaires. This study adopts the 18-item Need for Cognition scale from Cacioppo, Petty and Kao (1984).M

56、oreover, this study also employs the 5-point Likert-type scalethat ranges from “strongly disagree,” “disagree,” “neither disagree nor agree,” “agree,” to “strongly agree.” The stronger their agreement, the higher the score they receive. Participants indicate their degree of agreement with statements

57、 such as “I would prefer complex to simple problems,” “Thinking is not my idea of fun,” etc.Cronbachs coefficient of NFC is 0.808. Furthermore, this research adopts Thomas and Morwitz (2005) research as a reference of research method. Cronbachs coefficient of price cognition is 0.797. In order to en

58、courage participants to become involved in the study, they answer three questions related to a real-life purchase circumstance. Half the participants answer questions involving the same left digit (e.g., $990 vs. $950); the other half answer questions involving a lower left digit (e.g., $920 vs. $89

59、0). The products involved in this study are sneakers, MP3 players, and slippers (Nike and Adidas). A promotional price with a lower left digit that reduces 30 dollars and one with the same left digit that reduces 40 dollars are compared with the original price. The research instructs students to sel

60、ect the answer using the 5-point Likert-type scale in which 1 = “Strongly disagree” and 5 = “Strongly agree.” Participants select a number that represents the degree to which they agree or disagree with the statements “I think the promotion product is inexpensive” and “I think the promotional price
