Factor Price Equalization

Game Theory

Factor price equalization is an economic theorem, developed by Paul Samuelson in 1948, stating that under free trade in goods between countries that share the same technology and face the same goods prices, the prices of identical factors of production, such as wages or the return on capital, tend toward equality across those countries even without any actual movement of labor or capital between them. The result rests on a stylized two good, two factor model of trade and is treated as an extension of the Heckscher-Ohlin model.

Has Statement Form

Entity-backed identity for the statement-form enum value this theorem already carries, resolved to a mathematics concept by an explicit value-to-entity map (phase 3 bucket conversion, docs\design_entity_backed_browse_buckets_20260928.md). The statement-form fact itself stays on the theorem unchanged.
