Comparative Analysis / Comparative Advantage

INTRODUCTION
English translation pending.
CORE DEFINITION
Comparative value analysis holds that even a party with no absolute advantage in any field should specialize where its relative advantage is largest and trade for the rest. The core proposition rests on opportunity cost: the real cost of choosing one option is the next-best option forgone, so options should be compared by their relative differences rather than by absolute levels. The key qualification is that the comparison is only as good as the dimensions chosen, and weighting them introduces a judgment that must be made explicit.
SCAFFOLDING EFFECT
Reduce cognitive load
- Dimension set: choose the comparison dimensions and state clearly why each one of them matters. - Weighted scoring: score every option on each dimension and apply your explicit weights. - Opportunity test: ask what the next-best alternative costs you before you commit to anything.
Anchor fast decisions
Specializing where the relative advantage is greatest raises total output because each party gives up less of what it does best. Comparing absolute levels hides this, since a stronger party looks better everywhere and would seem to have no reason to trade. Opportunity cost makes the relative gap visible, which is what makes the division of labor rational even for the weaker party.
