Specific Factors Model
Updated 2026-08-09
INTRODUCTION
English translation pending.
CORE DEFINITION
A trade model developed by Jacob Viner and Ronald Jones, in which some factors of production, such as land or industry-specific skills, can be used in only one sector, while other factors are mobile. Opening to trade raises returns in export sectors and lowers them in import-competing sectors. The core claim is that factor mobility determines who gains and loses from trade. The qualification is that the model describes distributional effects within a country rather than whether the country gains overall.
SCAFFOLDING EFFECT
Reduce cognitive load
- Use Specificity Mapping: Identify which skills or assets can only be used in one setting and cannot transfer. - Use Loser Identification: Predict who will resist a change because their specific assets lose value. - Use Compensation Design: Build transition support for those whose specific factors are stranded.
Anchor fast decisions
When a factor cannot move between uses, its return is tied to the fate of the sector it serves, so a shift in demand or trade policy transfers income directly to or from its owners. Because the factor has no alternative employment, it bears the full adjustment rather than spreading the loss across the economy. This is why reforms that raise total output can still generate intense opposition from a concentrated, immobile group.
