Analyze the implications of the Stolper-Samuelson theorem in international trade theory. How does an increase in the relative price of a commodity impact factor rewards?

💡 Solution & Explanation

The Stolper-Samuelson theorem establishes that an elevation in the relative price of a good leads to an increase in the real return to the factor of production used intensively in manufacturing that good, while simultaneously reducing the real return to the other factor. For instance, in a labor-abundant country, rising export prices for labor-intensive goods raise real wages and lower real returns to capital owners. This theorem highlights why international trade generates distinct winners and losers within a domestic economy despite producing aggregate gains. It operates within the standard Heckscher-Ohlin framework of trade.
