Consumer behavior frameworks.

The Evolution of Consumer Behavior Theories

Introduction

The study of consumer behavior has evolved significantly over the past century, incorporating insights from various disciplines such as psychology, sociology, anthropology, and economics. This evolution has led to the development of numerous frameworks and models that provide a deeper understanding of how consumers make purchasing decisions. This essay explores the key stages in the evolution of consumer behavior theories, highlighting prominent frameworks and models that have shaped the field.

Early Theories: The Economic Man

1. Economic Theory:
   • Rational Choice Theory: Early consumer behavior theories were rooted in economics, where consumers were viewed as rational agents who make decisions to maximize utility. This perspective assumed that consumers have perfect information and make logical decisions based on price and quality.
   • Critique: This model was criticized for oversimplifying human behavior and ignoring emotional, psychological, and social influences.

Mid-20th Century: Psychological and Sociological Insights

2. Psychological Models:
   • Psychoanalytic Theory: Sigmund Freud’s theories suggested that unconscious desires and motivations drive consumer behavior. This approach emphasized the influence of emotions and inner conflicts.
   • Maslow’s Hierarchy of Needs: Abraham Maslow proposed that consumers are motivated by a hierarchy of needs, ranging from physiological needs to self-actualization. This model highlighted the importance of understanding different levels of consumer needs.
3. Behavioral Models:
   • Stimulus-Response Model (Pavlov): This model focused on how consumers respond to stimuli (such as advertising) and form habits. It emphasized the role of conditioning in shaping consumer behavior.
   • Howard-Sheth Model: John Howard and Jagdish Sheth developed a comprehensive model that integrated psychological and sociological factors. It included inputs (stimuli), hypothetical constructs (motivation, perception), and outputs (response), highlighting the complexity of consumer decision-making.

Late 20th Century: Cognitive and Decision-Making Models

4. Cognitive Models:
   • Information Processing Theory: This model viewed consumers as problem solvers who process information to make decisions. It emphasized the stages of information acquisition, processing, and decision-making.
   • Engel-Blackwell-Miniard (EBM) Model: This model expanded on information processing by detailing the consumer decision-making process in five stages: problem recognition, information search, evaluation of alternatives, purchase, and post-purchase behavior.
5. Attitude Models:
   • Fishbein and Ajzen’s Theory of Reasoned Action (TRA): This model posited that consumer behavior is influenced by attitudes toward the behavior and subjective norms. It introduced the concept of behavioral intentions as a predictor of actual behavior.
   • Theory of Planned Behavior (TPB): An extension of TRA, TPB added the component of perceived behavioral control, recognizing that consumers’ perceptions of their ability to perform a behavior also impact their intentions and actions.

Contemporary Theories: Integrative and Holistic Approaches

6. Social and Cultural Models:
   • Family Decision-Making Model: This model examined the role of family dynamics and decision-making processes within households. It considered factors such as roles, power dynamics, and conflict resolution.
   • Subculture and Social Class Models: These models explored how subcultural influences (e.g., ethnicity, religion) and social class impact consumer behavior and preferences.
7. Emotional and Experiential Models:
   • Emotional Decision-Making: This model emphasized the role of emotions in consumer behavior, recognizing that decisions are not purely rational but often driven by emotional responses.
   • Experiential Consumption: This model focused on the importance of experiences in consumer behavior, suggesting that consumers seek emotional and sensory gratification from products and services.
8. Digital Age and Technological Influence:
   • Technology Acceptance Model (TAM): This model explored how consumers adopt new technologies, considering factors such as perceived ease of use and perceived usefulness.
   • Big Data and Predictive Analytics: Modern theories incorporate data analytics to predict consumer behavior, leveraging large datasets to uncover patterns and trends.

Conclusion

The evolution of consumer behavior theories reflects the increasing complexity and multidimensionality of consumer decision-making. From early economic models that viewed consumers as rational agents to contemporary approaches that consider psychological, social, emotional, and technological influences, the field has grown to provide a more comprehensive understanding of consumer behavior. These frameworks and models continue to evolve, offering valuable insights for marketers and businesses seeking to connect with and understand their consumers in an ever-changing marketplace.

Consumer behavior frameworks help in understanding how and why consumers make purchasing decisions. These frameworks are crucial for marketers, as they provide insights into factors that influence consumer behavior. Here are some key consumer behavior frameworks:

1. The Purchase Decision Process Model

• Stages:
  1. Problem Recognition: Realizing there is a need or problem.
  2. Information Search: Gathering information about how to solve the need.
  3. Evaluation of Alternatives: Comparing different products or solutions.
  4. Purchase Decision: Choosing and buying a product.
  5. Post-Purchase Behavior: Evaluating the purchase decision and product satisfaction.

2. Maslow’s Hierarchy of Needs

• Application: Marketers use this hierarchy to understand and target consumer needs at different levels, from basic needs (food, safety) to higher-level needs (self-actualization).

3. AIDA Model

• Stages:
  1. Attention: Capturing the consumer’s attention.
  2. Interest: Creating interest in the product.
  3. Desire: Building a desire for the product.
  4. Action: Encouraging the consumer to take action (purchase).

4. The Theory of Planned Behavior (TPB)

• Application: This theory can predict consumer behavior by understanding their attitudes, subjective norms, and perceived behavioral control regarding a product or service.

5. Engel-Blackwell-Kollat Model

• Stages:
  1. Problem Recognition
  2. Information Search
  3. Alternative Evaluation
  4. Purchase Decision
  5. Post-Purchase Evaluation
• Components: Also includes influences such as individual differences, environmental influences, and psychological processes.

6. Howard-Sheth Model of Buyer Behavior

• Description: A comprehensive model that considers inputs (stimuli), perceptual and learning constructs, and outputs (purchase behavior). It emphasizes the complexity of consumer decision-making.

7. Consumer Decision Journey

• Stages:
  1. Initial Consideration Set: The consumer considers an initial set of brands.
  2. Active Evaluation: The consumer researches and evaluates brands.
  3. Moment of Purchase: The consumer selects a brand at the point of purchase.
  4. Post-Purchase Experience: The consumer evaluates their satisfaction and may become loyal or switch brands.

8. Loyalty Loop

• Stages:
  1. Consider: The consumer considers a set of brands.
  2. Evaluate: The consumer evaluates the brands.
  3. Buy: The consumer makes a purchase.
  4. Enjoy, Advocate, Bond: The consumer enjoys the product, advocates for it, and forms a bond, leading to repeat purchases.

9. McKinsey’s Consumer Decision Journey

• Stages:
  1. Trigger: Initial recognition of a need or problem.
  2. Initial Consideration: Forming a shortlist of brands.
  3. Active Evaluation: Gathering information and evaluating options.
  4. Moment of Purchase: Making the purchase decision.
  5. Post-Purchase Experience: Using the product and forming an opinion.
  6. Loyalty Loop: If satisfied, the consumer enters a loyalty loop and bypasses active evaluation in future purchases.

10. Fogg Behavior Model (FBM)

• Components:
  1. Motivation: The consumer’s desire to perform the behavior.
  2. Ability: The consumer’s capacity to perform the behavior.
  3. Triggers: Prompts that facilitate the behavior.

11. VALS Framework

• Description: A psychographic segmentation model that classifies consumers based on their values, attitudes, and lifestyles.
• Segments: Innovators, Thinkers, Believers, Achievers, Strivers, Experiencers, Makers, Survivors.
