Carrier / Substance

This table identifies what actually carries choice in microeconomic analysis. A carrier here is the concrete unit to which preferences, constraints, and decision rules are attributed. Each binary isolates a different way that decision-bearing substance can be specified—individual or aggregate, discrete or continuous, stable or unstable—before any optimization or behavioral reasoning is applied. The table’s role is to lock down the bearer of choice, not the act of choosing.

Taken together, the entries show that microeconomics does not operate on a single, universal decision-maker. Different models quietly switch carriers—individuals, representative aggregates, settled preference structures, noisy agents—often without acknowledgment. This matrix makes those assumptions explicit, preventing errors where properties of one carrier type are illegitimately transferred to another. By fixing the substance that carries choice, the analysis that follows remains structurally coherent rather than rhetorically convenient.


State / Phase

This table isolates choice-states as momentary configurations of decision-making. Each row classifies how a single decision condition behaves under a specific binary constraint—scale, continuity, equilibrium status, openness, uncertainty, scope, response shape, and behavioral regime. The binaries are ontological and fixed; what varies here is how a choice instantiates them. The result is a precise map of how individual decisions can exist, differ, and transition without importing assumptions from markets or macro systems.

Classical / QuantumPrice-Taking Choice StateThe agent treats prices and rules as given and ignores own impact on them.competitive consumer or firmAnticipatory Choice StateThe agent conditions action on expected reactions of others or the mechanism.auction bidding; Cournot quantity

Taken together, these classifications show that choice is not a vague act but a well-typed state with a determinate structure at any moment. Different choice-states obey different constraints, respond differently to change, and fail for different reasons. This table makes those differences explicit, ensuring that when we later move to interaction or aggregation, we do not smuggle in properties that belong to choices themselves rather than to markets or systems built from them.


Process / Event

This table classifies changes through time in individual decision-making without naming or reusing the section label itself. Each row isolates a distinct way that decision-related change can unfold—by scale, continuity, stability, openness, uncertainty, scope, proportionality, and evaluative regime. The focus is not on decisions as static objects, but on how adjustments, revisions, and learning sequences actually progress under different structural constraints.

Classical / QuantumEvaluation-Stable EvolutionCriteria remain definite throughout the change.standard neoclassical updatingEvaluation-Resolving EvolutionCriteria crystallize during the change itself.framing-driven preference formation

Read together, the entries show that changes in decision behavior are not a single kind of motion. Some revisions settle, others persist; some respond smoothly, others flip abruptly; some are driven entirely internally, others by continual external signals. By typing these forms explicitly, the table prevents collapsing all behavioral change into a generic “adjustment” story and fixes, in advance, what kinds of evolution a model is actually allowed to claim.


Structure / Configuration

This table characterizes the form of the decision space in microeconomic analysis. It focuses on how options, constraints, and tradeoffs are arranged, independent of how decisions are made or how they change over time. Each binary isolates a distinct structural property of the choice environment, making explicit the geometry, segmentation, stability, and scope of the configuration within which choice occurs.

Binary ClassFirst State NameFirst State DefinitionFirst State ExamplesSecond State NameSecond State DefinitionSecond State Examples
Micro / MacroIndividual Preference ConfigurationThe internal arrangement of options, constraints, and rankings for a single decision-maker, where local structure determines feasible and preferred choices.budget set with indifference curves; personal opportunity setAggregate Preference ConfigurationA population-level arrangement formed by aggregating individual preference and constraint structures into a collective pattern.market demand surface; income–preference distribution

Linear / NonlinearProportional Tradeoff GeometryA structure in which marginal substitutions preserve proportional response across the decision space.smooth indifference curvesKinked Tradeoff GeometryA structure containing thresholds, corners, or discontinuities that distort proportional response.minimum-consumption constraints; participation cutoffs
Classical / QuantumPredefined Ordering StructureA preference structure with fully specified rankings prior to evaluation.standard rational preference orderingContext-Resolved Ordering StructureA preference structure whose ordering is partially determined during evaluation itself.framing-dependent preference construction

Taken together, the entries show that choice depends as much on how possibilities are structured as on preferences themselves. Different configurations admit different kinds of tradeoffs, thresholds, and consistency conditions, constraining what rational behavior can even mean. By fixing these structures explicitly, the table prevents structural assumptions from being smuggled into behavioral claims and establishes a clear foundation for analyzing interaction and aggregation without category error.


System / Assembly

This table specifies how coherence is achieved in a choice system. Each row identifies a distinct mechanism by which options, constraints, evaluations, and rules bind together into a whole that can be treated as a single decision problem. The focus is not on agents or behavior, but on the condition that makes a choice problem well-defined at all under different structural binaries.

SAT – Domain – Categories – Unified Ontological Binary Matrix – System / Assembly – Choice (Microeconomic Foundations)

Binary ClassFirst State NameFirst State DefinitionFirst State ExamplesSecond State NameSecond State DefinitionSecond State Examples
Micro / MacroFeasible Set ClosureCoherence is achieved by resolving the intersection of options and constraints within a single bounded decision problem; the whole exists only insofar as feasibility is well-defined.individual budget set; firm cost–output feasibility regionAggregation Rule ClosureCoherence is achieved by a rule that combines many feasible sets into a single composite outcome space.representative-agent construction; social welfare aggregation
Discrete / ContinuousOption PartitionCoherence arises from membership in a finite partition of mutually exclusive alternatives governed by selection rules.menu choice; voting over candidatesMetric DomainCoherence arises from continuity over a metric space where proximity and magnitude define admissibility.quantity choice interval; effort continuum
Equilibrium / Non-equilibriumConstraint Satisfaction PointCoherence exists at configurations where all internal constraints and evaluations are jointly satisfied.utility-maximizing bundle; cost-minimizing input mixConstraint Conflict FieldCoherence fails because constraints and evaluations cannot be simultaneously satisfied, producing an unresolved system.infeasible budget–preference pairing; contradictory objectives
Open / ClosedExternally Conditioned Problem SpaceCoherence depends on inputs that originate outside the problem boundary, altering admissible configurations.choice under learning signals; institution-dependent optionsSelf-Contained Problem SpaceCoherence is fully determined by internally specified options, constraints, and rules.sealed optimization problem; fixed parameter choice
Deterministic / StochasticUnique Resolution MappingCoherence is enforced by a mapping from inputs to a single admissible outcome.strict preference ordering; lexicographic ruleMultiplicity EnvelopeCoherence permits multiple admissible outcomes absent further specification, requiring randomization or selection.random-utility representation; mixed admissibility set
Local / GlobalRestricted Feasibility WindowCoherence is defined only over a limited subset of constraints or horizons.short-run consumption feasibility; local choice frameCross-Constraint ClosureCoherence requires simultaneous satisfaction across linked domains or time periods.intertemporal budget closure; life-cycle feasibility
Linear / NonlinearAdditive Constraint IntersectionCoherence is produced by linear combination of constraints preserving proportional tradeoffs.separable utility with linear budgetBinding Limit TopologyCoherence is shaped by kinks, corners, or thresholds that alter admissible configurations.credit limits; minimum consumption constraints
Classical / QuantumPre-Specified Ordering SpaceCoherence relies on an ordering that is fully defined prior to evaluation.classical preference orderingEvaluation-Dependent Ordering SpaceCoherence depends on orderings that are partially constituted during evaluation itself.context-dependent preference construction

Read together, the entries show that a choice system is not a generic object but a coherence achievement that can succeed or fail in multiple ways. Feasibility closure, aggregation rules, metric continuity, constraint satisfaction, and ordering resolution each impose different limits on what outcomes are admissible. By fixing these system-forming mechanisms explicitly, the table prevents treating “choice” as a primitive and instead grounds it in the structural conditions that make decision problems intelligible.


Regime / Mode-of-Behavior

This table characterizes recurring behavioral regularities in choice—the ways decision behavior settles into repeatable forms over time. The focus is not on isolated decisions or static preferences, but on how patterns of choice stabilize, persist, or recur under different structural conditions. Each binary isolates a distinct mechanism by which repetition is maintained, whether through local routines, population-level regularities, smooth drift, abrupt switching, internal balance, or external entrainment.

SAT – Domain – Categories – Unified Ontological Binary Matrix – Regime / Mode-of-Behavior – Choice (Microeconomic Foundations)

Linear / NonlinearProportional SensitivityA recurrence in which behavioral change scales smoothly with incentives.marginal price responsivenessThreshold ActivationA recurrence structured around abrupt behavioral shifts once critical levels are crossed.participation cutoffs; default triggering
Classical / QuantumPreference PreservationA recurring behavior governed by stable evaluative criteria across repetitions.classical rational choice regularitiesPreference ResolutionA recurring behavior in which evaluative criteria are settled through repeated engagement.framing-dependent valuation patterns

Taken together, the entries show that choice behavior does not recur in a single uniform way. Some regularities are idiosyncratic, others systemic; some reproduce smoothly, others hinge on thresholds; some are self-maintained, others synchronized to external signals. By distinguishing these regime forms explicitly, the table prevents collapsing all repeated behavior into generic “habits” or “preferences” and provides a precise vocabulary for describing how and why choice patterns endure.


Role / Function / Position

This table identifies functional positions inside a choice environment—the loci where influence is exerted over how options are evaluated, constrained, or selected. A role here is not an agent or a behavior, but a position within the decision structure that shapes outcomes by admitting, weighting, stabilizing, or perturbing choice. Each binary highlights a different way influence can be localized or system-shaping, categorical or graded, stabilizing or pressuring, internal or externally referenced.

Micro / MacroMarginThe locus where a single tradeoff is evaluated locally, affecting one choice boundary at a time.one more unit vs not; hour worked at the marginScheduleA system-wide mapping that organizes many margins simultaneously into a coherent pattern.tax schedule; piecewise tariff
Discrete / ContinuousGateA categorical admission point that permits or denies options in stepwise fashion.eligibility cutoff; accept/reject ruleGradientA graded influence that varies smoothly across intensities without categorical jumps.price slope; utility gradient

Classical / QuantumEvaluatorA pre-specified ordering that ranks options independently of the act of choosing.classical utility functionResolverAn ordering that is settled during the act of choosing itself.context-constructed valuation

Taken together, the entries show that choice outcomes depend critically on which functional positions are active and how their influence is configured. Budgets, prices, rules, thresholds, and evaluators act as roles that channel decision-making in fundamentally different ways. By making these positions explicit, the table prevents conflating influence with preference or action and provides a precise vocabulary for describing how choice environments govern behavior before interaction or aggregation ever occurs.


Representation / Model-of-Reality

This table catalogs the distinct representational artifacts used to encode choice. Each row names a different kind of construct—maps, matrices, surfaces, frames, trees, schemas—that stands in for decision phenomena by emphasizing certain relations and suppressing others. The binaries specify how the artifact resolves detail, handles continuity, centers balance or pressure, admits context, encodes uncertainty, spans scope, preserves proportionality, and grounds ordering assumptions.

Taken together, the entries show that modeling choice is an interpretive act: selecting an artifact fixes what is visible, what is ignored, and what counts as explanation. Indifference maps foreground tradeoffs; matrices privilege categorical comparison; landscapes expose tensions; trees force paths; schemas enforce coherence across time. By naming these artifacts explicitly, the table prevents category drift and makes the limits of each modeling move transparent before any analysis proceeds.
