Rybczynski Theorem
This theorem is a property of the Heckscher-Olin Model, stating that, at constant prices, an increase of factor endowments will facilitate an increase in the production in an industry which uses that factor intensely. (i.e. Newly discovered caches of diamonds in South Africa would lead to increased diamond exportation. This could lead to less productivity in other industries. Suppose that due to a fixed level of employable people the diamond mines paid more for labor, laborers would move to that industry and abandon their previous positions.)
The Rybczynski theorem demonstrates how changes in a factor endowment affect the outputs of the goods when full employment is maintained. The theorem is useful in analyzing the effects of capital investment, immigration and emigration within the context of a given model.
This means that in general, an increase in a country's endowment of a factor will cause an increase in output of the good which uses that factor intensively, and a decrease in the output of the other good.
