    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.
