Revealed Preference Validation Against Indifference Curves

Use what actors actually choose under constraints to infer their trade-off curves, then test whether those inferred curves are coherent enough to guide decisions.

This draft fills the zero-any accepted-prime gap for indifference_curves by preserving the revealed-choice validation pattern: infer trade-off contours from observed behavior, test those contours for consistency, and bound the inference when constraints or choice architecture distort the signal.

Drafting note

The candidate was treated as a full archetype because no accepted archetype currently covers the inverse problem of deriving and validating indifference contours from actual choices. Nearby economics, optimization, and validation archetypes remain important boundaries, but they do not collapse the distinctive behavioral-inference move.

Compression statement

Revealed Preference Validation Against Indifference Curves treats observed choices as evidence about a decision maker’s implicit substitution rates. It reconstructs candidate indifference contours from choice data, checks them against budget, feasibility, dominance, and consistency constraints, and flags where observed behavior contradicts the claimed preference model.

Canonical formula: valid_preference_surface = observed_choice_set × feasible_budget_set × inferred_substitution_rates × consistency_tests × anomaly_explanation_boundary

Variants

Narrower or domain-specific specializations that share this archetype's core structure. Recognized variants are established; candidate variants are provisional.

Consumer Choice Consistency Audit · domain variant · recognized

Uses purchasing, substitution, and basket data to infer whether consumer choices support stable trade-off contours.

  • Distinct from parent: It specializes the parent to market and consumer-choice settings.
  • Use when: Retail, subscription, or marketplace choices are observed repeatedly; Prices, bundles, or attributes vary enough to expose substitution behavior; The task is to validate actual preference rather than only predict sales.
  • Typical domains: retail, subscription pricing, consumer product design
  • Common mechanisms: revealed preference consistency matrix, marginal substitution estimator, indifference region visualization

Policy Revealed Trade-Off Inference · domain variant · recognized

Infers social or institutional trade-offs from policy choices, votes, budgets, or implementation decisions.

  • Distinct from parent: It adds legitimacy, aggregation, and representation concerns to the base inference problem.
  • Use when: Public values are claimed but actual policy choices allocate resources differently; Budget, voting, land-use, or regulatory behavior can be observed; The analyst must distinguish declared value from enacted trade-off.
  • Typical domains: environmental policy, municipal budgeting, public-choice analysis
  • Common mechanisms: stated vs revealed gap report, choice architecture confound audit

Benefits Menu Trade-Off Validation · domain variant · recognized

Uses selections among salary, leave, flexibility, insurance, training, and other benefits to infer employee trade-off contours.

  • Distinct from parent: It specializes the parent to compensation and benefits design.
  • Use when: A benefits or compensation menu forces real trade-offs; Different groups choose different bundles; Designers need to validate which benefits are substitutes or complements.
  • Typical domains: human resources, benefits administration, workforce planning
  • Common mechanisms: budget set reconstruction, choice bundle normalization, stated vs revealed gap report

Revealed Preference Anomaly Review · risk or failure variant · recognized

Focuses on choices that violate inferred indifference contours and diagnoses whether the violation reflects preference change, constraint, framing, or data error.

  • Distinct from parent: It is a diagnostic subtype centered on failed validation.
  • Use when: Dominated, cyclic, or unstable choices appear; The analyst must decide whether to revise the curve or explain the anomaly; Choice architecture or information quality may have distorted the signal.
  • Typical domains: behavioral economics, consumer protection, digital choice architecture
  • Common mechanisms: dominance violation scan, preference reversal probe, choice architecture confound audit
