The Heckscher–Ohlin Theorem, which is concluded from the Heckscher–Ohlin model of international trade, states: trade between countries is in proportion to their relative amounts of capital and labor. In countries with an abundance of capital, wage rates tend to be high; therefore, labor-intensive products, e.g. textiles, simple electronics, etc., are more costly to produce internally. In contrast, capital-intensive products, e.g. automobiles, chemicals, etc., are less costly to produce internally. Countries with large amounts of capital will export capital-intensive products and import labor-intensive products with the proceeds. Countries with high amounts of labor will do the reverse.
