The Leontief Paradox is an economic finding that contradicts the Heckscher-Ohlin theory, which suggests that countries will export goods that utilize their abundant factors of production more intensively. Specifically, the paradox reveals that the United States, which is capital-abundant, actually exports labor-intensive goods and imports capital-intensive goods, contrary to what the theory would predict. This unexpected outcome raises questions about the accuracy of factor endowments in determining trade patterns.
