Supply and demandcausesPriceEstablished
supply and demand causes price.
Mechanism: Price is set where the quantity supplied meets the quantity demanded; a shift in either moves the price.

supply and demand is part of microeconomics.
Mechanism: Supply and demand is the core microeconomic model: it explains how the price and quantity of a good emerge from the interaction of buyers and sellers.

Structural role & consequence
Interpreted from the current atlas graph — what the connections mean, not just how many there are.
14% of its relationships cross field boundaries, reaching 3 other disciplines — unusual in a discipline where most concepts stay within their field.
structural · Structural graph analysis — not a claim of importance, causation or history.
Directly enables 1 concept; following enables/causes relations, 1 concept is downstream across 1 discipline.
structural · Follows only enables/causes dependency edges — not general relatedness.
Currently dark in the atlas: no key date stored · 7 of 7 of its relations lack claim-level evidence.
atlas representation · Describes the current Thinking OS representation, not the state of the world.
Exercises 2 annotated mental models — a concept that connects several thinking patterns.
curated · Curated annotations, not a derived measure.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
- No dated history stored — the atlas records no key date for this concept. atlas representation
Conditions
- Read structurally — most of its relationships carry no external evidence yet, so claims here are graph-derived. structural
Dependency radial
What this concept builds on (left) and what it makes possible (right) — derived from dependency and causal relations.
Seen through each discipline
How this concept sits in each of its fields — derived from its real connections in the graph, not asserted.
Through this lens it connects to Microeconomics, Real estate, Price and Demand.
Through this lens it connects to Consumer choice theory.

Feedback loop
A loop where an effect feeds back to change its own cause. Reinforcing loops amplify change; balancing loops resist it.
Ask: does the result push the system further in the same direction, or pull it back?
Equilibrium
A state where opposing processes balance so the whole stops changing overall — even though activity continues underneath.
Look for two forces pushing against each other; the system settles where they cancel, and a disturbance is met by a restoring push back toward balance.
