Brand Equity
also: brand value · brand strength
Definition
Brand equity is the premium, in sales, pricing power, and LTV, attributable to the brand identity beyond functional product attributes. It is an asset that compounds with consistent investment and decays with over-optimization toward short-term performance marketing, making brand-vs-performance allocation a portfolio problem.
Brand equity manifests as pricing power (willingness-to-pay above commodity), preference loyalty (resistance to switching), and reduced acquisition cost (direct and organic traffic). Brand investment is long-duration and imperfectly observable, performance marketing is short-duration and tightly measurable, making the allocation trade-off a Markowitz-style portfolio optimization problem.

Brand vs. Performance: A Portfolio Optimization Framework Using Markowitz Theory for Marketing Budget Allocation
Finance solved the allocation problem in 1952. Marketing still argues about it in 2026. Markowitz's portfolio theory, applied to marketing channels instead of stocks, reveals an efficient frontier that makes the brand-versus-performance debate quantitatively resolvable.

MTA models overestimate retargeting by 340% and underestimate display by 62%. The fix isn't better heuristics, it's abandoning correlational attribution entirely in favor of causal graphs.

Personalized Promotion Optimization: Uplift Modeling to Identify Who Needs a Discount vs. Who Would Buy Anyway
70% of promotional spend goes to customers who would have purchased at full price. Uplift modeling identifies the 30% whose behavior actually changes with a discount, and ignores the rest. The math isn't complicated. The organizational willingness to stop blanket discounting is.
