Study Notes

The Market-Based Assets Theory of Brand Competition

  • Kotler's Segmentation, Targeting, Positioning (STP) theory is still prevalent in marketing, but it doesn't entirely explain brand success.
  • Empirical studies show brand market share is often stable despite marketing mix changes.
  • Brand competition is more complex than solely optimizing the marketing mix.

Beginnings of Segmentation, Targeting, Positioning (STP) Theory

  • The concept emerged in the 1950s.
  • McCarthy's 4Ps (product, price, place, promotion) became a framework.
  • The 4Ps extend the perfect competition model by adding demand drivers beyond price.
  • Marketers use techniques like mix modeling and choice modeling to optimize marketing mixes.
  • Despite efforts, predicting successful products/brands remains difficult.

Empirical Observations on Brand Competition

  • Observation 1: Competing Brands Share Customers:
    • The Duplication of Purchase Law states that brands share buyers.
    • Customer cross-purchasing correlates with brand size.
    • Smaller brands grow by attracting customers from larger competitors.
  • Observation 2: Competing Brands Sell to Similar Customers:
    • Buyers of competing brands have similar profiles (demographics, lifestyles).
    • Segmentation strategies based on brand differences often don't apply.
  • Observation 3: Competing Brands Are Weakly Differentiated:
    • Few consumers perceive substantial differences between brands.
    • Brand image data shows little distinction.
    • Most customers do not associate brands with unique perceptions.
  • Observation 4: Competing Brands Have Similar Satisfaction Scores:
    • Customer satisfaction doesn't directly predict brand loyalty or size.
    • Customer satisfaction ratings are not consistently repeatable over time.
  • Observation 5: Competing Brands Have Predictable Loyalty:
    • Buyer loyalty is reliably predictable from brand size.
    • Double Jeopardy Law: Bigger brands have somewhat higher loyalty than smaller brands.
    • Loyalty is not dependent on uniqueness, perceived value, or differentiated positioning.

Market-Based Asset Theory

  • The theory states that accessible and perceived brands are driven by the size of their customer base.
  • Key assets are mental & physical availability.
  • Mental availability: brand's presence in consumers' considerations.
  • Physical Availability: ease of purchase.
  • Larger brands tend to have higher mental and physical availability.

Implications

  • Targeting is not the sole key driver of brand growth.
  • Instead, expanding the brand's customer base (mental and physical availability) is crucial.

Areas for future research

  • Overlapping mental and physical availability.
  • Measuring mental and physical availability.
  • Forecasting investments for mental availability.
