What this concept builds on and what it makes possible — derived from the atlas’s dependency, causal and structural relations, not from every related edge.

Comparative advantagedepends onOpportunity costEstablished
comparative advantage depends on Opportunity cost.
Mechanism: Comparative advantage is defined by opportunity cost: you should produce what you give up least to make, then trade for the rest.

System context
Economies of scaleis aComparative advantageEstablished
economies of scale is a kind of comparative advantage.
Mechanism: Economies of scale can be a source of comparative advantage: producing at large volume lowers unit cost, so a producer can supply more cheaply than others.

Interpreted from the current atlas graph — what the connections mean, not just how many there are.
Currently dark in the atlas: 3 of 3 of its relations lack claim-level evidence.

Strengths & constraints
Constraints
- Evidence coverage currently thin in the atlas — few of its relationships carry claim-level evidence. atlas representation
Conditions
- Its dependency reading rests on 1 foundation relation. structural
- 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

What it looks like
Concrete cases that make this idea recognisable in the real world.
The lawyer and the assistant
A lawyer types faster than her assistant, but each hour typing costs her a far more valuable hour of legal work. She gains by doing law and letting the assistant type — comparative advantage, despite her absolute advantage at both.
Check yourself
A quick check against a common misconception. Nothing is scored — picking the tempting-but-wrong answer just flags an idea worth revisiting.
Which statement is correct?
If you're better at everything, you should do everything yourself.
Gains from trade come from RELATIVE, not absolute, efficiency. Even someone better at every task benefits by specialising where their edge is largest and letting others do the rest — both sides end up with more.

Trade-offs
When getting more of one thing means accepting less of another, because resources or constraints are limited.
Ask what you give up (the opportunity cost) to gain what you want.
Optimization
Searching a space of options for the best one under constraints — following a gradient of 'better' toward a maximum or minimum.
Ask: what is being maximised or minimised, and what limits the search? Beware settling in a 'local' best that isn't the global one.
