The '''Stolper–Samuelson theorem''' is a [[theorem]] in [[Heckscher–Ohlin model|Heckscher–Ohlin]] [[trade]] theory. It describes the relationship between relative prices of output and relative [[Factors of production|factor]] returns—specifically, [[real wage]]s and [[Real versus nominal value (economics)|real]] returns to capital.

The theorem states that—under specific [[economic]] assumptions (constant [[returns to scale]], [[perfect competition]], equality of the number of [[Factors of production|factors]] to the number of products)—a rise in the [[relative price]] of a good will lead to a rise in the real return to that factor which is used most intensively in the production of the good, and conversely, to a fall in the real return to the other factor.
