  • Consumer Behavior Consumer behavior refers to the buying behavior of final consumers -- individuals and households who buy goods and services for personal consumption. Model of Consumer Behavior Marketers control the stimuli or inputs consisting of the four Ps: Product, Place, Price, and Promotion. Environmental and situational influences, though perhaps beyond the control of the marketer, also influence many consumer choices. But what happens between the marketing stimuli input and the buyer’s response or output? That “black box” processing is the central question for marketers. Teaching Tip: You may wish to discuss the “buyer’s black box” in more detail at this stage. Students sometimes become involved in the controversy regarding the presence or absence of consciousness in consumers. Consider using a two-side in-class discussion: Side A: Experimental psychologists argue that what we call consciousness is merely a set of complex learned responses -- an ordinary physiological function. Side B: Sociologists and social psychologists argue that consciousness is greater than the sum of its physiological parts. For marketers, the issue is sometimes linked to free will: Do marketers create needs by conditioning consumers? Do marketers offer need-fulfillers to needs consumer’s create in their “black box?” Model of Consumer Behavior This CTR corresponds to Figure 5-1 on p. 135 and to the material on pp. 134-135.
  • Characteristics Affecting Consumer Behavior This CTR relates to Figure 5-2 on p.135 and previews the material on pp. 135-150. Influences on Consumers Cultural . Culture is the most basic influence on a person's values, priorities, and beliefs. Cultural shifts make marketing opportunities although most such changes are in secondary rather than core cultural values. Subcultures are important markets as these groups are often significantly different in their needs to warrant different marketing approaches. Social. Social class is determined by a combination of income, occupation, education, wealth and other variables. Social factors within one's class that affect consumer behavior include reference groups & aspirational groups. Families also exert strong social influences. Finally, each relationship a person has with his or her group carries with it certain roles and status that may carry consumptive responsibilities. Personal . Major personal factors are age and life cycle stage, occupation, economic situation, life style and personality/self-concept. Texts vary in their treatment of the PLC stages but it is clear that singles buy different products than do young marrieds with small children. Occupations differ in time constraints and social pressures to conform that affect consumption decisions. Lifestyles measured by AIO or VALS typologies can reveal different consumption patterns across otherwise dissimilar groups. The unique characteristics of each person that make up their personality also affect behavior. Psychological . Maslow's hierarchy reminds marketers that need states vary in their intensity or motivation. Perception is the process of organizing stimuli and is influenced by selective exposure, distortion, & retention. Learning occurs in response to the presentation of information linked to relevant drives, cues, responses, and reinforcement only some of which is under the control of the marketer. Beliefs and attitudes, though shaped by cultural and social forces, may vary considerably on the individual level.
  • Social Factors This CTR relates to the material on pp. 140-142. Group Influence on Brand Choice Groups vary in their influence on product and brand purchases as illustrated on the CTR. Consumers belong to several different membership groups. Primary Groups. Primary groups are those with which we have regular but informal interaction. These include family, friends, neighbors, and co-workers. Secondary Groups. Secondary groups are those with which we have more formal and less regular interaction such as religious groups, professional associations, and trade unions. Reference Groups. These groups serve as direct (face-to-face) or indirect points of comparison and evaluation in a person’s formation of attitudes or behavior. Aspirational Groups. This type of group is one to which the individual wishes to belong and emulates in adopting behaviors appropriate to that group. Opinion Leaders. These are people within a reference group who exert influence over others due to special knowledge, skill, personality, or other characteristic.
  • Factors Affecting Consumer Behavior: Personal This CTR corresponds to Table 5-2 on p. 142 and the material on pp. 142-146. Personal Factors Age and Family Life-Cycle Stage. Buyers’ choices are affected by changes in their age and family structure over time. Young singles have different tastes in clothes, furniture, food, and recreation than do middle aged persons with their own children. Older consumers continue to change in their preferences and additionally acquire new buyer needs such as increased health care needs. Occupation. A person’s occupation carries with it distinct consumptive needs. White collar workers need different clothes than blue collar workers. Also, occupations usually carry their own subcultural norms and values that influence buyer behavior. Economic Situation. Means constrain buyer behavior for almost everyone except for the most wealthy. Personality and Self-Concept. Personality refers to the unique psychological characteristics that lead to relatively consistent and lasting response to one’s own environment. Self-concept is the basic perception that people have about who they are. Lifestyle Lifestyle is a person’s pattern of living as expressed in her or his activities, interests, and opinions. Determining lifestyle involves measuring AIO dimensions -- the Activities , Interests , and Opinions of consumers. Psychographics. Lifestyle measures combined with demographic information can identify distinct market segments for consumer products and services. The best known of these methods, VALS 2, is addressed on the following CTR.
  • VALS 2 Segments This CTR corresponds to Figure 5-3 on p. 144 and relates to the material on pp. 143-145. VALS 2 Segments The VALS 2 Segmentation by lifestyle incorporates both psychological aspects such as principles, status, and action orientations as well as resource-based orientations (abundant versus minimal). Descriptions of each area include: Fulfilleds. Fulfilleds are principles oriented individuals who are mature responsible well-educated professionals. Leisure centers around the home but they are also well-informed about the world. High income but practical, value-oriented consumers. Believers. Believers principles oriented individuals who have more modest incomes, are conservative and predictable consumers who favor American products. Achievers. Achievers are status oriented individuals who get satisfaction from jobs and families. Conservatives who respect authority. Products show off success. Strivers. Strivers are status oriented individuals who seek to emulate achievers but have fewer resources. Experiencers. Experiencers are action oriented individuals who like to affect the environment in tangible ways. This group is active and outgoing and likes new things. Makers. Makers are action oriented individuals who also like to affect their environment but in more practical ways. They value self-sufficiency, family, and have little interest in the larger world. Actualizers. Actualizers are resource oriented individuals with the highest incomes and so many resources that they can indulge any or all self-orientations. Image is an expression of taste, independence, and character. They can buy anything; need nothing. Strugglers . Strugglers are resource oriented individuals who have the lowest income and tend to be brand loyal. Strugglers are concerned with survival.
  • Maslow’s Hierarchy of Needs Maslow suggests that lower level needs must be satisfied before individuals become motivated to satisfy higher level needs. Thus consumers will respond to lower level products and promotions until those needs are met. Only then can other marketing offers be of interest. Needs include: Physiological. Physical needs such as hunger, thirst, and bodily functions are the lowest level need and require satisfaction before other needs become important to the individual. Sometimes this helps students understand the difference between needs and wants. A thirsty person may still want an expensive car but if thirsty enough will take a drink of water. Safety. Safety needs for security and protection are the next level needs in the hierarchy. So long as physiological needs are met, safety needs will take precedence over other needs. Fear appeals for consumer products are often linked to safety needs. Social. Human beings are social, gregarious animals. We group together in part to fulfill physiological and safety needs but also because we enjoy and need the company of others. Going to malls to "hang out" fulfills social needs. Esteem. To be recognized as an individual fulfills esteem needs. Self-esteem is the value a person places on himself or herself. As lower level needs become more stable, esteem needs become more important to the individual. Self-actualization. Beyond esteem needs very successful people may still be driven to improve themselves and "accomplish something." These people are driven to self-actualize their potential. Maslow’s Hierarchy of Needs This CTR relates to the material on p. 146-147 and corresponds to Figure 5-4.
  • The Buyer Decision Making Process This CTR corresponds to Figure 5-6 on p. 153 and relates to the material on pp. 152-156. Teaching Tip: Consider asking students to describe some of their purchases decisions made at the beginning of the term and link them to steps in the process. Stages in the Buyer Decision Process Need Recognition. Problems are recognized when people sense a difference between an actual state and some desired state. Problem recognition can be triggered by either internal or external stimuli. Information Search. Consumers vary in the amount of information search they conduct. Information search may be a survey of information stored in memory or may be based upon information available externally. Search effort varies from heightened awareness corresponding to increased receptivity for relevant information to active information search modes where the person expends some energy to obtain information that is desired. External information vary in their informational and legitimizing characteristics. Riskier decisions usually elicit more search behavior than non-risky decisions. Evaluation of Alternatives. Following information search, the person compares decisional alternatives available. Criterion for evaluation compares product attributes of the alternatives against degrees of importance each attribute has in meeting needs, beliefs about the product or brand's ability and utility, and an evaluation procedure that ranks the alternatives by preference that forms an intention to buy. Purchase Decision. - The individual buys a product. Purchasing other than the intended product may be due to attitudes of others exerted after the evaluation of alternatives is completed or unexpected situational factors such as point of purchases promotions that affect the alternatives' ranking. Post-purchase Behavior. This involves comparing the expected performance of the product against the perceived performance received. Cognitive dissonance describes the tendency to accentuate benefits and downplay shortcomings.
  • Stages in the Adoption Process The new product adoption process parallels the buyer decision process but focuses more on the interaction of consumer needs with product adoption. The new product adoption process may work best to explain how regularly used products requiring re-purchase are considered for inclusion in the consumer's consumptive behavior patterns but may also apply to some durables as well. Awareness. In this stage the consumer is aware of the new product but lacks further information about it. Interest. The consumer is motivated to seek information about the new product. Evaluation. The consumer determines whether or not to try the new product. Trial. The consumer tries the new product on a small scale to test its efficacy in meeting his or her needs. Trial can be imagined use of the product in some cases. Adoption. The consumer decides to make use of the product on a regular basis. Stages in the Adoption Process This CTR relates to the material on p. 157.
  • Adoption of Innovations This CTR corresponds to Figure 5-7 on p. 157 and relates to the material on pp. 157-158. Individual Differences in Innovativeness Innovators. Innovators include the first 2.5% of buyers who adopt a new product idea. Innovators help get the product exposure but are not often perceived by the majority of potential buyers as typical consumers. Innovators like risk taking and enjoy buying new products. Innovators may purchase at skimming prices. Discussion Note: You might discuss the ethical implications of skimming. Is it fair? Also, are there cost considerations associated with new product development that make skimming to recover high start up costs more ethical than it may seem? Early Adopters. Early Adopters comprise about 13.5% of the buyers who adopt new products. This group serves as opinion leaders to the rest of the market and their product usage outcomes serve as motivation to later buyers to get the product. Early Majority. Early Majority are some 34% of buyers adopting the product. They are deliberate consumers who adopt new ideas before the average person but seldom lead the market. Late Majority. Late Majority comprise another 34% of buyers adopting the product. This group is skeptical of new products and only buys after the majority of the market has tried it. Laggards. Laggards are the final 16% of adopters and are tradition-bound. They are suspicious of change and only adopt innovation that have already become something of a tradition.
  • Influences on the Rate of Adoption of New Products This CTR relates to the material on pp. 158-159. Teaching Tip: The adoption of innovations may be initially confusing to students but they will usually become involved in discussion when new products of importance to them are used as examples. Product Characteristics Influences Relative Advantage. This refers to the degree to which the innovation appears superior to existing products. The greater the perceived relative advantage, the sooner the innovation will be adopted. Compatibility . This refers to the degree to which the innovation fits the values and experiences of the potential consumers. Increased compatibility will accelerate adoption of the innovation. Complexity . This refers to the degree to which the innovation is difficult to understand or use. Greater complexity will slow the rate of adoption of the innovation. Divisibility . This refers to the degree to which the innovation can be tried on a limited basis. Greater divisibility will help increase the rate of adoption of the innovation. Communicability . This refers to the degree to which the results of using the innovation can be observed or described to others. Greater communicability will increase the rate of adoption of innovation.
  • Characteristics of Organizational Markets Market Structure and Demand. Business markets have far fewer buyers than consumer markets. Business markets are much more geographically concentrated. Business demand is derived demand coming from the demand for the consumer goods the organization produces. Demand is more inelastic and more fluctuating. Nature of the Buying Unit. Business markets have more buyers and more professional purchasing procedures. Purchasing agents may be career professionals highly trained in how to buy better. As purchases become more complex, more people are likely to become involved in the purchase decision. Types of Decisions. Business buying decisions may be more complex due to the large amounts of money involved, technical specification considerations, and the interaction and coordination of more people in the buying process. Decision Process. Beyond the complexity of the decision business buying is more formalized, often with written procedures. Also, business buying decisions feature buyer-seller relationships that are more dependent upon each other than consumer buying situations. Both buyer and seller have fewer options to do business elsewhere than do consumer buyer and sellers. Other Characteristics Direct Purchasing. Business buyers usually buy direct from producers. Reciprocity . Business buyers often practice reciprocity, selecting suppliers who also buy from them. Leasing . Many businesses lease rather than buy equipment. Leasing gains a number of advantages over buying such as having more capital, having newer products, and tax incentives. Characteristics of Business Markets This CTR corresponds to Table 6-1 on p. 171 and relates to the material on pp. 170-172.
  • A Model of Business Buyer Behavior This CTR corresponds to Figure 6-1 on p. 173 and the material on pp. 172-173. A Model of Business Buyer Behavior The Environment. The business buyer operates in a competitive environment consisting of two categories: Marketing Stimuli. Marketer controlled stimuli consist of the product, place, price, and promotion. Other Stimuli . As with consumer markets, other stimuli consist of the forces in the economic, technological, political, cultural, and competitive environments. However, group membership in the business organization and participation in the business buying process affects how these environmental forces influence decision making. The Buying Organization. The buying organization is influenced by the overall organization -- its corporate culture and values, traditions, and procedures and regulations. The buying center and the business buying decision process also differs from consumer buying influences and is discussed on a following CTR. Buyer Responses. Buyer responses in business buying situations often consist of more alternatives than those available to consumers. Supplier choice, order quantities, delivery terms, service options, and payment terms are often more negotiable than they are to the consumer.
  • Major Types of Buying Situations Straight Rebuy. This is an industrial buying situation in which the buyer routinely reorders something without any modifications in the order. Marketers of industrial supplies seek to establish this type of relationship with the customer. When buyers place straight rebuys, competitors have little or no chance of making a sale. Modified Rebuy. This is an industrial buying situation in which the buyer wants to modify product specifications, prices, terms, or suppliers. This increases the number of participants in the buying decisions thus increasing the combination of influences on the decision. "In" suppliers worry that competitors will gain some business. "Out" suppliers recognize the situation as an opportunity. New Task Buying. This is an industrial buying situation in which the buyer purchases a product or service for the first time. New task buying is the most complex of buying decision processes made by a company. It is also both the greatest opportunity and challenge to the marketer. Marketers must consider that new task buying situations often arise in response to still-emerging problems seeking solutions. Business Buying Situations This CTR relates to the material on pp. 173-175.
  • Buying Centers This CTR relates to the material on pp. 175-177. Participants in Business Buying Centers Users . These are members of the organization who will use the product or service. Users often initiate the buying proposal and help define product specifications. Influencers . These are people who affect the buying decision. They often help define specifications and provide information for evaluating alternatives. Technical personnel are particularly important influencers. Buyers . These are the people with the formal authority to select the supplier and arrange terms of purchase. Buyers may influence product specifications, but their major role is in selecting vendors and negotiating. Deciders . These are the people who have the formal or informal power to select or approve the final suppliers. Gatekeepers . Gatekeepers are those people who control the flow of information to others. Gatekeepers are extremely important to anyone trying to gain the cooperation of buying center members, especially in widely-dispersed organizations.
  • Major Influences on Business Buying This CTR corresponds to Figure 6-2 on p. 178 and the material on pp. 177-179. Major Influences on Business Buying Environmental Factors. Industrial Buyers are heavily influenced by the economic environment especially the level of primary demand, economic outlook, and the cost of money. Materials shortages are also increasing in importance. Organizational Factors . These factors stem from each organization's objectives, policies, procedures, and ways of doing business. Marketers must identify how each of these elements are manifest in a particular company. Interpersonal Factors . Interpersonal influences center on group dynamics and the interplay of personalities and organizational roles. Buyer roles within the buying unit may differ not only from organizational factors but from the interpersonal interaction of the individuals involved as well. Individual Factors. A person's age, status, education, professional specialty, and overall personality and attitudes affect how they participate in organizational buying decisions. It may be difficult for the marketer to identify individual factors directly.
  • Stages in Business Buying Process This CTR corresponds to Table 6-2 on p. 179 and relates to the material on pp. 179-184. Stages in Business Buying Problem Recognition . Problem recognition can result from internal or external stimuli. They may emerge from an identified shortage or ideas for improvements recognized by buyers. General Need Description. The buyer describes the overall characteristics and quantities of the needed item. For complex items, this step may require coordinating the efforts of many specialists. Product Specification. A developmental team must translate general needs into product specifications. An engineering value analysis team may look at alternative designs to reduce production costs. Supplier Search. The buyer conducts a search for the best vendors for the product specifications. Proposal Solicitation. The buyer invites qualified suppliers to submit proposals covering the terms of supply and support. Selected proposals may be asked to make formal presentations. Supplier Selection. The buyer selects suppliers based upon a combination of technical competence and service record and reputation. Negotiation of specific terms may occur before final selection, especially on price. Order Routine Specification. The buyer specifies the details of the supplier's contract listing technical specifications, delivery terms, policies for return and warranties, and quantities needed. Sellers will seek blanket contracts binding them closer to the buyer. Performance Review. The buyer will review how the supplier contract is working for the company and may continue, amend, or drop the seller.
