(4) The Effect of Retailer Price Promotion on FMCG Brand Substitution and Use Complementary Purchase Student:Yu-Mei, Wang. Advisors:Dr. Edwin, Tang. Institute of Business and Management National Chiao Tung University ABSTRACT The past studies are limited in foods and do not prove whether price sensitive buyers purchase complementary or not. We will extend the study of promotional effects to FMCG category and, more importantly, to be empirical work on different price level of substitution and complementary products to advance promotional and merchandising practice. The data is collected by Dominick’s Database, which contains canner data of 85 stores, 29 categories in the US. Because the database is so huge and based on the topic which is about brand substitution and complementary, we only choose toothbrush and tooth paste for our sample in this study from 277 to 328 week. Our finding shows that price promotion appears to be an effective tool for brand substitute and full-margin complementary purchase of low unit price but do not useful for brand substitution of high unit price. There are a few possible of high price brand in tooth brush category may have complementary purchase. Most retailers do not consider the effect of promotion on sales of non promoted product. As a consequence, retailers may draw misleading conclusions about promotional effectiveness. The success of retail price promotions depends on such factors as the ability of the promoted items to draw customers to the store, the profit (or loss) on the promoted item, the cannibalization that occurs when consumers switch away from regular-priced items to promoted items, and the boost in sales volumes of non-promoted items. If retailers can use scanner data and have professional marketing employee to suit consumer characteristics and environment changes with scientific method to make a market strategy and planning, it is expected to meet strong sales and growth targets, achieved through strategies for retailers.. Key words: price promotion, substitution, complementary. ii.

(9) I. Introduction FMCGs, common abbreviation for “Fast moving consumer goods”, are products that have a quick shelf, at relatively low cost and do not require a lot of thought, time and financial investment to purchase. Fast Moving Consumer Goods is also a classification that refers to wide range of frequently purchased consumer products including: safety matches, food items, bathing soaps, cosmetics, teeth cleaning products, hand-wash detergent powder, tinned food, food paste, towels, table salt, edible oil, tomato paste, monosodium glutamate, food seasonings, butter, margarine, breakfast beverages. Three of the largest and best known examples of Fast Moving Consumer Goods companies are Nestlé, Unilever and Procter & Gamble. Examples of FMCG brands are Coca-Cola, Kleenex, Pepsi and Mars. According to the study of Ministry of Economic Affairs (MOEA) and Institute for Information Industry, the FMCG sale is approximately 20,000million US dollars every year. In the retailer grocery industry, category management is the process of managing category of products for greater profitability and customer value. The concept of efficient store assortments addresses the critical interface between distributors and consumers, and attempts to improve sales, shelf-space utilization and customer value. It is based on category management, ie managing categories (groups of closely related complementary products) for greater profitability and customer value, rather than managing individual brands or the vendor’s gross margin by purchase (Gruen and Shah, 2000). This process consists of category definition, establishing product hierarchies (taxonomies); category execution, applying strategies for assorting, pricing and promotion products; and category performance measurement. Category management is a data-driven process and, as a result, can benefit from point-of-sale (POS) scanner data. (Peter et al. 2004) The recent availability of scanner data to retail chains has resulted in a shift in power from manufacturers to retailers (Kumar & Leone, 1988). Research on UPC scanner data has been actively pursued by marketing academics since the mid-1980s and many papers have been published in the major marketing journals since then. One reason is that scanner data is easy to acquire and can give practitioners better tools for understanding their markets (e.g., approaches to analyze consumer response and market segmentation) and for making marketing mix decisions (e.g., setting prices and determining promotion spending). 1.

(10) Several academic studies address particular aspects of category management, including partner relationships for category management and category performance (Gruen and Shah, 2000); key determinants (eg assortment breadth) of effective category management (Dhar et al. 2001); and profitability of category management under an everyday low price (EDLP) strategy (Hoch et al. 2001). But little is known about the breadth and depth of brand substitution and complementary across product categories (Walter, 1991). The study will focus on the breadth and depth of retail price promotions on FMCG brand substitution and use complementary purchase using scanner data. For instance, when buying toothbrushes which are on price promotion, we will also consider if a tooth paste is needed. Shampoo and bath soap is another example. It is because one who is used to soap will not use bath soap to take a bath and the other more complex factors that we will not consider product substitution. The present study which is different from the past stands on product pricing and investigates the effect of retailer price promotion on FMCG brand substitution and use complementary. It is expected to meet strong sales and growth targets, achieved through strategies for retailers. The study is organized as follows. First, we briefly introduce the background that included what FMCG is, research motive and objective. The next section presents the theoretical and summary of empirical research on price promotion effects. The research method—data estimate procedure and methodological aspects of price promotion in substitution and complementary purchase—is in the third section, followed by the research hypotheses. The forth section presents the results of this study that is the most important section. The final section is a discussion of the results, an analysis of the study’s limitations, and suggestions for directions of future research.. 2.

(12) II. Literature review A. Buying behavior Consumer decision making varies with the type of buying decision. The decision to buy toothpaste, a tennis racket, a personal computer, and a new car are all very different. Blackwell, Miniard, and Engel (2001) mention that individual characteristics and purchase characteristics are the evaluative criteria in purchase decision process. These determinants of purchase characteristics are type of product, timing variables, price/quality, and situation. And there are many events showing consumer’s involvement is not high among frequently purchasing product. In this study, FMCGs are products that have a quick shelf, at relatively low cost, and do not require a lot of thought, time and financial investment to purchase. FMCG also refers to wide range of frequently purchased consumer products. Generally speaking, customers are most price-sensitive to products that cost a lot or are bought frequently. They are less price-sensitive to low-cost items or items they buy infrequently. They are also less price-sensitive when price is only a small part of the total cost of obtaining, operating, and servicing the product over its lifetime. Companies, of course, prefer to work with customers who are less price-sensitive. Tom Nagle offers a list of factors associated with lower price sensitivity, for instance, buyers are less aware of substitutes and the product is assumed to have more quality, prestige, or exclusiveness. We assume that price/quality is the important purchase variable among FMCG in this study. We group buyers into price sensitivity, low price sensitivity and others. In this study, we are interesting in price sensitivity and low price sensitive buyers. For price sensitive buyers, the price is only what they care. For example, they would like to buy the cheapest product or pay a lot of attention to what is on promoted. They scrimp on purchasing. But for low price sensitive buyers, they are loyalty to specific brand or pay attention to high quality products that always associate with high price. However, the past studies do not take notice of product pricing. Companies need to understand the price sensitivity of their customers and prospect and the trade-offs people are willing to make between price and product characteristics. As we know, the complementary purchase of technical products is common. For example, while buying a digital camera, we will purchase a memory card which is use complementary as well. Also, the past studies are also limited in foods (eg. spaghetti and 4.

(13) spaghetti sauce) and do not prove whether price sensitive buyers purchase complementary or not. We will extend the study of promotional effects to FMCG category and, more importantly, to be empirical work on different price level of substitution and complementary products to advance promotional and merchandising practice. In this article, we did not use questionnaire but scanner data. The reasons is that scanner data is easy to acquire, can give practitioners better tools for understanding their markets, and purchase intension is still different from purchase behavior which accords with actual situation.. 5.

(14) B. Price promotion The retail price promotions affect sales of non-promoted products and competitor performance is critical to retailers as they attempt to increase the effectiveness of promotion and improve their competitive position in the marketplace (Progressive Grocer 1989). Kumar & Leone (1988) mention for manufacturers and retailers, they all expect to increase their sales. The manufacturer’s primary objective in promoting a brand is to increase sales. In contrast, the retailer’s primary objective is to maximize store profit. A retailer’s promotional strategy could affect sales by causing category switching, increased consumption, stockpiling, brand substation, and/or store substitution. Retail promotion enables both retailer and manufacturer to meet objectives when brand substitution occurs within the store and customers from other stores switch, or cross-shop, to take advantage of the promotion. Gupta’s (1988) finding that the increasing sales on the promotion period are resulted from brand switching, purchase time acceleration and stockpiling. The important of brand choice is that brand switching accounts for 84% of the overall sales increase due to promotions in the coffee category. Bell et al.(1999) work on Gupta’s study and generalize two effects that are secondary demand effect( brand switching effect) and primary demand expansion. Their finding is also support that secondary demand effect accounts for 75% of the overall sales increase due to promotions. The success of retail price promotions depends on such factors as the ability of the promoted items to draw customers to the store, the profit (or loss) on the promoted item, the cannibalization that occurs when consumers switch away from regular-priced items to promoted items, and the boost in sales volumes of non-promoted items.. 6.

(15) C. Brand substitute Treating brands within a product category as substitutes is also consistent with the economic definition of substitutes proposed by Henderson and Quandt (1958): “…two commodities are substitutes if both can satisfy the same need.” From economist perspective, the relationship between substitution and complementary is about the change of relative price. Classic examples of substitute goods include margarine and butter, or petroleum and natural gas (used for heating or electricity). The fact that one good is substitutable for another has immediate economic consequences: insofar as one good can be substituted for another, the demand for the two kinds of good will be bound together by the fact that customers can trade off one good for the other if it becomes advantageous to do so. Thus, an increase in price for one kind of good (ceteris paribus) will result in an increase in demand for its substitute goods, and a decrease in price (ceteris paribus, again) will result in a decrease in demand for its substitutes. Thus, economists can predict that a spike in the cost of wood will likely mean increased business for bricklayers, or that falling cellular phone rates will mean a fall-off in business for public pay phones. In other words, good substitution is an economic concept where two goods are of comparable value. Car brands are an example. While someone could argue that Ford trucks are much different from Toyota trucks, If the price of Ford trucks goes up enough, some people will buy Toyota trucks instead. In brand substitution area of researches, it is starting with Frank and Massy’s (1967) work. And Moriarty (1985) examined the brand substitution effects of retail promotions and found some evidence that promotions enhance substitution. Kumar and Leone (1988) use store-level scanner data and investigate the effect of retail store price promotion, featuring, and displays on sales of brands of disposable diapers within a city. Featuring refers to the retailer advertising the brand at a specific price in a weekly store circular. Displayed refers to the retailer providing a specific in-store presentation of the product, either through in-aisle or end-of-aisle displays. Price-cut refers to the retailer reducing the price of the product in comparison to its regular everyday price. Within a store, 7.

(16) price promotion produced the largest amount of brand substitution, followed by featuring and displays. They all indicate that price promotion is positively associated with one brand’s sales. But little empirical research has been done on complementary effects of promotions. Walters (1991) indicates the presence of substitution effects within a product category and supports conventional wisdom (Davidson, Sweeney, and Stampfl). His study showing that substitution effects are asymmetrical and the brands with high market shares often gain sales at the expense of their low share competitors.. 8.

(17) D. Complement Balderson (1956) describes two types of complementary relationship. Products are use complements if they are consumed together; products are purchase complements if they are purchased together. From a retail perspective, the purchase complementary of all items included in a consumer’s shopping basket. Product complements are products that are used in conjunction with one another to satisfy some particular need (Henderson and Quandt 1958). Complement or complementary good is defined in economics as a good that should be consumed with another good; its cross elasticity of demand is negative. This means that, if goods A and B were complements, more of good A being bought would result in more of good B also being bought. An example of complement goods is hamburgers and hamburger buns. If the price of hamburgers falls, more hamburger buns would be sold because the two are usually used together. In marketing, complementary goods give additional market power to the company. It allows vendor lock-in as it increases the switching cost. A few types of pricing strategy exist for complementary good and its base good: Pricing the base good at a relatively low price to the complementary good - this approach allows easy entry by consumers (e.g. consumer printer vs ink jet cartridge). Pricing the base good at a relatively high price to the complementary good - this approach creates a barrier to entry and exit (e.g. golf club membership vs green fees) A basic notion in retailing is that promotions also affect consumer purchasing patterns by stimulating purchases of non-promoted complements to the promoted products (Berman and Evans 1989; Walters 1988). Promotions also can cause consumers to substitute a reduced-margin brand for a full-margin brand. Complementary effects created by promotions are of special interest to retailers because significant increase in sales of full-margin complementary products can offset decreases in sales of full-margin substitute brands (Walters 1991). McAlister and Totten (1985) indicates that the level of interaction often is substantial and the promoted brand can influence significantly both competitive brands (decrease their sales) and complementary products (increase their sales). Mulhern (1989) and Walters (1991) also show the promotion of one product can stimulate sales of complement. 9.

(20) 29 Bathroom tissues. tti. 128. 1571901. Because the database is so huge and based on the topic which is about brand substitution and complementary, we only choose toothbrush and tooth paste for our sample in this study. The reason is sales of toothbrush and tooth paste will not change a lot by season. And for many categories, the identification of product complements is difficult. Toothbrush and tooth paste are simple and suitable in this study. Although the data in Dominick’s Database covered a period of 399 weeks, we only selected 52 weeks to investigate the two categories. First, we calculate total sales of each brand from 277 to 328 week (we show the calendar in appendix A). Second, we calculate unit price of each brand. In this study, the prices of toothpaste are per ounce and the prices of toothbrush are one unit. Third, we choose the high unit price with high market share in the categories and the low unit price is in the same process. Table 3 and Table 4 show the three toothbrush and toothpaste brands with high unit price. Table 5 and Table 6 show the three toothbrush and toothpaste brands with low unit price. The information of stores was included in our study (appendix D & E).. TABLE 3 the high unit price brand of toothbrush UPC 3500055300 30041085562 3700000869. BRAND COLGATE(CO) ORAL B(OB) CREST (CR).

(22) B. Modeling procedure To measure the effect of retail price promotion on sales of substitutes and complements, retail price promotional activities on the brand and its substitutes and complements within a store are in the model. In this study, dependent variable is sales of one brand and independent variables are the retail prices of competing or substitute brands and complement brands in tooth brush and toothpaste category.. (1). Salesi =Σχiβi. whereβi = retail price of high-priced brand 1 to 6. It is specified here for high price level brand CO..

(2). Salesj =Σγjαj. whereαj = retail price of low-priced brand 1 to 6. For example, SalesPE=γ0+γ1αPE +γ2αBU +γ3αOB +γ4αKCR +γ5αKCL +γ7αKCO The equation contains variables pertaining to the brand itself (α1), the brand’s substitutes in the product category (α2 and α3), and the brand’s complements (α4, α5 and α6).. 14.

(24) In economics, elasticity is the proportional change in one variable relative to the proportion change in another variable. The concept of elasticity can be used whenever there is a cause and effect relationship. In economics, the price elasticity of demand (PED) is an elasticity that measures the nature and degree of the relationship between changes in quantity demanded of a good and changes in its price. Price elasticity of demand is measured as the percentage change in quantity demanded that occurs in response to a percentage change in price. For example, if, in response to a 10% fall in the price of a good, the quantity demanded increases by 20%, the price elasticity of demand would be 20%/(− 10%) = −2. (Case & Fair, 1999). In general, a fall in the price of a good is expected to increase the quantity demanded, so the price elasticity of demand is negative as above. Note that in economics literature the minus sign is often omitted and the elasticity is given as an absolute value. (Case & Fair, 1999). Because both the denominator and numerator of the fraction are percent changes, price elasticities of demand are dimensionless numbers and can be compared even if the original calculations were performed using different currencies or goods. An example of a good with a highly inelastic demand curve is salt: people need salt, so for even relatively large changes in the price of salt, the amount demanded will not be significantly altered. Similarly, a product with a highly elastic demand curve is red cars: if the price of red cars went up even a small amount, demand is likely to go down since substitutes are readily available for purchase (cars of other colors). It may be possible that quantity demanded for a good rises as its price rises, even under conventional economic assumptions of consumer rationality. Two such classes of goods are known as Giffen goods or Veblen goods. Another case is the price inflation during an economic bubble. The unicist approach to price elasticity solved the problem integrating the demanded quantity, its subjective value and the price. The formula used to calculate the coefficient of price elasticity of demand is. 16.

(25) Using all the differential calculus:. where: P = price, Q = quantity When the price elasticity of demand for a good is elastic (Ed > 1), the percentage change in quantity is greater than that in price. Hence, when the price is raised, the total revenue of producers falls, and vice versa. When the price elasticity of demand for a good is inelastic (Ed < 1), the percentage change in quantity is smaller than that in price. Hence, when the price is raised, the total revenue of producers rises, and vice versa. When the price elasticity of demand for a good is unit elastic (or unitary elastic) (Ed = 1), the percentage change in quantity is equal to that in price. Hence, when the price is raised, the total revenue remains unchanged. The demand curve is a rectangular hyperbola. When the price elasticity of demand for a good is perfectly elastic (Ed = ∞), any increase in the price, no matter how small, will cause demand for the good to drop to zero. Hence, when the price is raised, the total revenue of producers falls to zero. The demand curve is a horizontal straght line. A ten-dollar banknote is an example of a perfectly elastic good; nobody would pay $10.01, yet everyone will pay $9.99 for it. When the price elasticity of demand for a good is perfectly inelastic (Ed = 0), changes in the price do not affect the quantity demanded for the good. The demand curve is a vertical straight line; this violates the law of demand. Elasticity is an important concept in understanding the different types of goods as they relate to the theory of consumer choice. In economics, the cross elasticity of demand or cross price elasticity of demand measures the responsiveness of the quantity demanded of a good to a change in the price of another good. It is measured as the percentage change in demand for the first good that occurs in response to a percentage change in price of the second good. For example, if, in response to a. 17.

(26) 10% increase in the price of fuel, the quantity of new cars that are fuel inefficient demanded decreased by 20%, the cross elasticity of demand would be -20%/10% = -2. In the example above, the two goods, fuel and cars, are complements - that is, one is used with the other. In these cases the cross elasticity of demand will be negative. In the case of perfect complements, the cross elasticity of demand is negative infinity. Where the two goods are substitutes the cross elasticity of demand will be positive, so that as the price of one goes up the quantity demanded of the other will increase. For example, in response to an increase in the price of fuel, the demand for new cars that are fuel efficient (hybrids for example) will also rise. In the case of perfect substitutes, the cross elasticity of demand is positive infinity. Where the two goods are independent the cross elasticity demand will be zero, as the price increase the quantity demanded will be zero, an increase in price 'zero quantity demanded'. In case of perfect independence, the cross elasticity of demand is zero.. (3) Cross-Price Elasticity = (percentage change in amount of A bought) divided by (percentage change in price of B). Take low price brands for example,.

Where the two goods are substitutes the cross elasticity of demand will be positive, so that as the price of one goes up the quantity demanded of the other will increase.. 18.

(28) C. Hypotheses 1. Promotional effects For manufacturers and retailers, they all expect to increase their sales. The manufacturer’s primary objective in promoting a brand is to increase sales. In contrast, the retailer’s primary objective is to maximize store profit (Kumar & Leone, 1988). Most of studies support by conventional wisdom and past empirical research (Neslin, Henderson, and Quelch ,1985;. Blatterg Eppen, and Lieberman ,1981; McAlister and Struse ,1988; Guadagni. and little, 1983; Moriarty ,1985). The first hypothesis is that retail promotional activity stimulates significant increases in sales of the promoted product—no matter the product pricing is high or low. Therefore, H1: retail price promotional activities conducted on a brand of high price level have a significant positive impact on sales of the promoted brand.(+) H2: retail price promotional activities conducted on a brand of low price level have a significant positive impact on sales of the promoted brand. (+). 2. Brand substitution effects Numerous studies with diary panel data (Dodson, Tybout, and Sternthal, 1978) and aggregate sales data (Kumar and Leone, 1988) indicate that price promotions enhance brand substitution effects (Chevalier, 1975; Moriarty, 1985). We assume that: H3: retail price promotional activities conducted on a brand of high price level have a significant positive impact on sales of brand substitutes in the product category. (+) H4: retail price promotional activities conducted on a brand of low price level have a significant positive impact on sales of brand substitutes in the product category. (+). 20.

(29) 3. Use complementary effects A basic notion in retailing is that promotions also affect consumer purchasing patterns by stimulating purchases of non-promoted complements to the promoted products (Berman and Evans 1989; Walters 1988). Complementary effects created by promotions are of special interest to retailers because significant increase in sales of full-margin complementary products can offset decreases in sales of full-margin substitute brands (Walters 1991). McAlister and Totten (1985) indicates that the level of interaction often is substantial and the promoted brand can influence significantly both competitive brands (decrease their sales) and complementary products (increase their sales). Mulhern (1989) and Walters (1991) also show the promotion of one product can stimulate sales of complement. H5: retail price promotional activities conducted on a brand of high price level have a significant positive impact on sales of brand complements.(+) H6: retail price promotional activities conducted on a brand of low price level have a significant positive impact on sales of brand complements. (+). At the first, we have the tooth brush and tooth paste scanner data from 277 to 328 week and save as two EXCEL that one is the dataset of high price brands and the other is low price brands. We use SAS program to analysis data. The equation 1 (Salesi =Σχiβi) is for hypothesis 1,3, and5. The equation 2 (Salesj =Σγjαj) is for hypothesis 2,4, and 6. The equation 3, Cross-Price Elasticity = (percentage change in amount of A bought) divided by (percentage change in price of B), can measured as the percentage change in demand for the item that occurs in response to a percentage change in price of the toothpaste and tooth brush.. 21.

(33) A. Promotional effects H1 and H2 state that price promotions on a brand stimulate brand sales. The hypothesized sign associated with the relationship is negative – that is, as prices decrease (increase), sales increase (decrease). The results indicate that price promotions had a significant impact on brand sales for all promoted brands. In this type of research, collinearity may exits to reduce our explanation. TABLE 10 and TABLE 13 show cross elasticity. TABLE 11 is the correlation matrix for high price level brands, and TABLE 14 is for low price level brands. The finding shows that the data support H1 and H2, that is, retail price promotional activities conducted on a brand of high and low price level have a significant positive impact on sales of the promoted brand, expect for high price brands (KCO and KTO) in the toothpaste category. Over all speaking, in the tooth brush and toothpaste category, as prices decrease (increase), sales increase (decrease).. B. Brand substitution effects H3 states that price promotions on one brand of high price level have a positive impact on sales on substitute brands in the category, and H4 states that price promotions on one brand of low price level have a negative impact on sales on substitute brands. The hypothesized sign associated with this relationship is positive – that is, high (low) prices on one brand mean high (low) sales of substitute brands. In low price level of the tooth brush category, for example, PE gained sales at the expense of OB (TABLE 12 and TABLE 13). In particular, we find a strong correlation between KCL price and KCO price (TABLE 14). Therefore, it must be careful to explain the brand substitution effect of KCL and KCO. The results show that the number of substitution effects varied among product category and among brands of high (low) price level. For example, for low price level brands, significant substitution effects were found in 67% of possible cases when price promotions were conducted in tooth brush category, whereas significant substitution effects were found in 100% of the cases in toothpaste. For high price level brands, only price promotions on CR toothbrush resulted in significant decreases in sales of CO tooth brush in high price level, whereas there is no significant evidence to indicate that price promotions impact on sales of brand substitutes in toothpaste category. The overall pattern of results provides modest rejects 25.

(34) H3 but supports H4, that is, price promotions on one brand of high price level have a negative impact on sales on substitute brands in the category, and price promotions on one brand of low price level have a positive impact on sales on substitute brands. So far as we have seen that there are several interesting substitution patterns. First, most of the substitution effects were asymmetrical, as one brand built sales at the expense of another brand but did not lose sales as a result of that brand’s price promotion activities. For example, for low price level brands, price promotion on PE tooth brush significantly reduced sales of BU tooth brush, yet price promotion on BU did not significantly reduce sales of PE tooth brush. Only in toothpaste of low price level, price promotion on KCR toothpaste significantly reduced sales of KCL toothpaste, and price promotion on KCL toothpaste significantly reduced sales of KCR toothpaste as well. Second, price promotions appear to be effective in enhancing substitution of low unit price brands in the toothpaste category. That is very different from Walters’s study. In 1991, Walter’s study indicates that in no instance did a low market share brand gain sales at the expense of a brand with higher market share. But in our study, KCR toothpaste is the popular brand with high market share in toothpaste category, and price promotions enabled KCL toothpaste, a brand with lower market share and lower unit price, to gain sales at the expense of KCR toothpaste. And PE toothpaste is at the same situation. Hence, price promotion appears to be an effective tool for brands of low unit price in their categories. The overall pattern of results provides modest rejects H3 but supports H4.. C. Use complementary effects The hypothesized sign associated with this relationship is negative (i.e., low prices on a brand mean high sales of complementary products). H5 posits that price promotions on a high price level brand have a significant positive impact on sales of brand complements to the promoted brand. And H6 posits that price promotions on a low price level brand have a significant positive impact on sales of brand complements to the promoted brand. As brand substitution effects, the results show that the number of substitution effects varied among product category and among brands of high (low) price level. For example, for low price level brands, significant substitution effects were found in 67% of possible cases when price promotions were conducted in tooth brush and toothpaste category. For high price 26.

(35) level brands, significant substitution effects were found in 67% of possible cases when price promotions were conducted in tooth brush category, whereas there is no significant evidence to indicate that price promotions impact on sales of brand substitutes in toothpaste category. The patterns of results pertain to complementary effects provides some interesting insights into price promotional effects. First, like substitution effects, substitution effects were not symmetrical. That is, in toothpaste of low price level, price promotion on KCR toothpaste significantly increased sales of BU tooth brush, and price promotion on BU toothpaste do not increase sales of KCR toothpaste as well. Second, price promotions did not appear to enhance complementary purchase of high unit price brands. Hence, price promotion appears to be an effective tool for complementary purchase of low unit price in their categories but do not useful for complementary purchase of high unit price. The overall pattern of results provides modest reject H5 but support H6.. 27.

(36) V. Conclusion The study focus on the breadth and depth of retail price promotions on FMCG brand substitution and use complementary purchase using scanner data. For instance, when buying toothbrushes which are on price promotion, we will also consider if a tooth paste is needed. Shampoo and bath soap is another example. The present study is different from the past and stands on product pricing and investigates the effect of retailer price promotion on FMCG brand substitution and use complementary. The finding shows that the data support H1 and H2, that is, retail price promotional activities conducted on a brand of high and low price level have a significant positive impact on sales of the promoted brand, expect for high price brands (KCO and KTO) in the toothpaste category. Over all speaking, in the tooth brush and toothpaste category, as prices decrease (increase), sales increase (decrease).And the study provides modest rejects H3 but supports H4, that is, price promotions on one brand of high price level have a negative impact on sales on substitute brands in the category, and price promotions on one brand of low price level have a positive impact on sales on substitute brands. Third, price promotion appears to be an effective tool for complementary purchase of low unit price in their categories but do not useful for complementary purchase of high unit price. The overall pattern of results provides modest reject H5 but support H6. The finding shows that price promotions on a brand stimulate brand sales. The results indicate that price promotions had a significant impact on brand sales for all promoted brands in tooth brush and toothpaste categories. In other words, as prices decrease (increase), sales increase (decrease). The result also shows price promotions on one brand of low price level have a positive impact on sales on substitute brands in the category, but price promotions on one brand of high price level have a negative impact on sales on substitute brands. And, it shows most of the substitution effects were asymmetrical, as one brand built sales at the expense of another brand but did not lose sales as a result of that brand’s price promotion activities. The most interesting is that the result is very different from Walters’s study. In 1991, Walter’s study indicates that in no instance did a low market share brand gain sales at the expense of a brand with higher market share. Complementary effects of promotions were called by one retail executive in the study “the essence of merchandising,” yet complementary effects rarely have been explored 28.

(37) by researchers and probably are not exploited enough by retailers. We find that price promotion appears to be an effective tool for complementary purchase of low unit price in their categories but do not useful for complementary purchase of high unit price, especially for toothpaste of high price. The study results have some interesting implication for retailers and manufactures. For manufacturers and retailers, they all expect to increase their sales. The manufacturer’s primary objective in promoting a brand is to increase sales. In contrast, the retailer’s primary objective is to maximize store profit (Kumar & Leone, 1988). Jack Trout, author of positioning, cautions that some product categories tend to self-destruct by always being on sale. They must do carefully or find that their profits are much less than planned. The success of retail price promotions depends on such factors as the ability of the promoted items to draw customers to the store, the profit (or loss) on the promoted item, the cannibalization that occurs when consumers switch away from regular-priced items to promoted items, and the boost in sales volumes of non-promoted items. In this article, FMCGs are having a quick shelf, at relatively low cost and do not require a lot of thought, time and financial investment to purchase. Because of FMCG product characteristics, most of retailers will set a low price or promotions frequently and think it is useful. In the words of marketing consultant Kevin Clancy, those who target only the price-sensitive are “leaving money on the table.” Our finding shows that price promotion appears to be an effective tool for brand substitute and full-margin complementary purchase of low unit price but do not useful for brand substitution of high unit price. There are a few possible of high price brand in tooth brush category may have complementary purchase. Most retailers do not consider the effect of promotion on sales of non promoted product. As a consequence, retailers may draw misleading conclusions about promotional effectiveness. Scanner data is easy to acquire and can give practitioners better tools for understanding their markets (e.g., approaches to analyze consumer response and market segmentation) and for making marketing mix decisions (e.g., setting prices and determining promotion spending). If retailers can use scanner data and have professional marketing employee to suit consumer characteristics and environment changes with scientific method to make a market strategy and planning, it is expected to meet strong sales and growth targets, achieved through strategies for retailers.. 29.

(38) Certain limitations of our work and database provide opportunities for future research. First, the price promotional effects investigated may be particular to the product categories examined. Second, all of these factors ,for example, retailing advertising , promotional frequency, the degrees of discount and channel power may enhance or inhibit substitution and complementary effects, and future research should include these variables in studies of promotional effects. Third, thought we examine two types of buyer that all are associated with price. It would be interesting to understand how category characteristics influence purchase characteristics. Future research can make a questionnaire to evaluate attribute and combine scanner data to analyze. Therefore, the promotions we analyze reflect the real world .. 30.
