Introduction to Consumer Behaviour: Concept, Scope, and Applications

Why did millions of Indian families switch from traditional mustard oil or ghee to refined sunflower and olive oils? Why do college students queue up outside electronic stores to purchase the latest smartphone on zero-cost EMI?

Every business decision—from pricing a tube of toothpaste to launching an electric vehicle—hinges on understanding Consumer Behaviour.

1. What is Consumer Behaviour?

Formal Definitions

According to Leon G. Schiffman and Leslie Lazar Kanuk: “Consumer behaviour is the behaviour that consumers display in searching for, purchasing, using, evaluating, and disposing of products and services that they expect will satisfy their needs.”

According to Engel, Blackwell, and Mansard: “Consumer behaviour involves the acts of individuals directly involved in obtaining and using economic goods and services, including the decision processes that precede and determine these acts.”

Customer vs. Consumer: A Vital Distinction

Marketer’s Takeaway: A marketer must appeal to both! The advertisement must convince the buyer/customer regarding nutrition and price, while satisfying the consumer/user in taste and comfort.

2. The Scope of Consumer Behaviour

Consumer behaviour does not begin at the retail cash register, nor does it end when the receipt is printed. It spans the complete cycle of consumer life:

   [ Pre-Purchase Activities ]  ──> Need recognition, online search, comparing reviews.
              │
              ▼
   [ Purchase Activities ]      ──> Store visit, bargaining, payment mode (UPI, EMI).
              │
              ▼
   [ Post-Purchase Activities ] ──> Usage, satisfaction, reviews, loyalty, disposal.

1. What they buy: The specific product categories, brands, and variations selected.
2. Why they buy: The underlying motives, psychological drives, and social pressures behind the purchase.
3. When they buy: Seasonal trends (e.g., gold during Dhanteras/Diwali, air conditioners in April).
4. Where they buy: E-commerce apps (Amazon, Flipkart), quick-commerce (Blinkit, Zepto), or local Kirana shops.
5. How often they buy: Frequency of purchase (daily milk, monthly groceries, once-a-decade cars).
6. How they evaluate and dispose: How consumers maintain, recycle, or discard products after use.

3. Interdisciplinary Nature of Consumer Behaviour

Consumer behaviour is an applied behavioral science that draws theories from multiple fields:

• Psychology: Explains internal individual drives (motivation, perception, attitudes, personality).
• Sociology: Explains external societal forces (family influence, social classes, caste, community norms).
• Social Psychology: Explains how group pressure and peer recommendations shape choices.
• Economics: Explains price elasticity, consumer income budgets, and rational utility.
• Anthropology: Explains regional traditions, religious rituals, and cultural values.

4. Practical Applications of Consumer Behaviour in Marketing

Understanding consumer behavior drives core marketing strategy:

A. Market Segmentation, Targeting, and Positioning (STP)

• Segmentation: Dividing a diverse market into homogeneous groups based on behavioral traits (e.g., budget smartphones for students vs. luxury flagship models for corporate executives).
• Targeting: Choosing the most profitable segments to serve.
• Positioning: Creating a distinct mental image in the consumer’s mind (e.g., Volvo positioned as “Safest Car”, Maggi positioned as “2-Minute Quick Snack”).

B. Product Design and Packaging

• Designing products that solve authentic customer pain points (e.g., single-use shampoo sachets in India making premium brands affordable to rural daily-wage earners).

C. Pricing Strategies

• Setting prices based on consumer perceived value rather than pure production cost (e.g., psychological pricing like Rs. 999 instead of Rs. 1000).

D. Distribution Channels

• The explosive rise of Quick Commerce (Blinkit, Zepto, Instamart) in India happened because urban consumers value 10-minute convenience over walking to the market.

E. Public Policy and Government Regulations

• Guiding consumer safety warnings (e.g., mandatory pictorial warnings on cigarette packs, star ratings on energy-saving air conditioners).
