Willingness to pay (WTP) is the invisible variable every article is trying to read, set, or exploit — but each measures it through a different proxy.

- **A022** makes WTP explicit: [[concept-subjective-value]] scatters buyers along the [[prereq-downward-sloping-demand|demand curve]], and discounting is the craft of meeting each buyer at *their* WTP without letting full-price buyers pocket the difference ([[concept-profit-cannibalization]]).
- **A009** proposes a radical WTP sensor: customers who build [[concept-customer-workaround|workarounds]] are [[concept-effort-as-payment|paying in effort]], and that effort is a revealed-preference signal of latent WTP the firm hasn't captured.
- **A023** works the other direction — [[concept-value-anchoring]] tries to *install* a non-zero WTP where 'free' would otherwise set the [[concept-reference-price-trap|reference price]] at $0.
- **A008** shows consumers pricing the *renewal default* into their WTP for a trial — [[claim-consumers-aware-of-inertia|sophisticated consumers]] discount auto-renew offers, causing [[concept-acquisition-suppression]].
- **A064** treats WTP structurally: SME order sizes were too small until AI lowered [[prereq-cac-and-ltv|CAC]], making low-WTP segments profitable ([[concept-ai-driven-tam-expansion]]).
- **A066** supplies the precondition: [[concept-found-time]] and [[concept-mental-bandwidth]] are needed before a consumer can even *form* WTP for a complex product.

The open thread: nobody can quantify it cleanly — see [[xd-quantification-gap]] ([[question-quantifying-effort]], [[question-optimal-hurdle-friction]], [[question-token-amount-optimization]]).
