Linder hypothesis

From Wikipedia, the free encyclopedia

The Linder hypothesis was proposed by economist Staffan Burenstam Linder in 1961 as a possible resolution to the Leontief paradox, which questioned the empirical validity of the Heckscher-Ohlin theory (H-O). H-O predicts that patterns of international trade will be determined by the relative factor-endowments of different nations. Those with relatively high levels of capital in relation to labor would be expected to produce capital-intensive goods while those with an abundance of labor relative to capital would be expected to produce labor intensive goods. H-O and other theories of factor-endowment based trade had dominated the field of international economics until Leontief performed a study that showed H-O to be wrong empirically. In fact, Leontief found that the United States (then the most capital abundant nation) exported primarily labor-intensive goods. Linder proposed an alternative theory of trade that was consistent with Leontief's findings. The Linder hypothesis presents a demand based theory of trade in contrast to the usual supply based theories involving factor endowments. Linder hypothesized that nations with similar demands would develop similar industries. These nations would then trade with each other in similar but differentiated goods.

Subsequent examinations of the Linder hypothesis have observed a "Linder effect" consistent with the hypothesis, however, this effect does not account for all the world's pattern of trade.
