In one of the most widely discussed tests of the factor proportions theory, Leontief attempted to reveal the relative factor proportions structure of U.S. participation in international trade. A serious weakness in Leontief’s analysis was that he failed to take into account the effect of tariffs policy on the pattern of trade. Travis emphasized that the tariff policies adopted by different trading countries often distorted the pattern and composition of traded commodities.
Leontief’s input-output analysis has been used by the World Bank, the United Nations, and the U.S. Leontief attempted to defend his conclusion by putting forward the argument that the productivity of an average American worker was equivalent to three foreign workers. Therefore, the United States was a labour surplus country, which was likely to export labour- intensive goods.

He alleged that capital must be excluded from the model and instead he compared the skill of manufactures traded between pairs of developed and developing countries (Clarke and Kulkarni 2009, p.119). The study showed that sophisticated goods are usually exported by developed countries, thus “theory often seems to perform rather well” . Other notables developed prominent researches that corroborate H-O theory, such as David Clifton , Brecher and Schott . Many economists have rejected the H–O theory in favor of a more Ricardian model, where technical differences decide comparative advantage.
The paradox was attacked by Valvaris-Vail on the ground that it was based on the input-output table showing the fixed input-output co-efficients. In view of this, it is not surprising that the labour- abundant United States exports those products, which have relatively greater labour-intensity. There is no doubt that the productivity of labour is higher in the United States than in other countries.
However, the other conventional assumptions of the model appear to be very restrictive and they need to be reinvented again, particularly that technology is not identical everywhere. Income inequality between skilled and unskilled workers may be attributed to skill-biased technological change rather than an increase on trade. Berman et al showed that this is a plausible explanation for the escalation on wage premiums for skilled workers and the upswing proportion of skilled workers employed within an industry. A third criticism is that it ignores economies of scale – which means production increases as output increases – so when input levels change for one factor, output levels might change for another factor too.

- These products were imported because the U.S. simply could not produce them.
- The economists undertook intense research for re-examining both the H-O theory and Leontief paradox.
- He was also one of the first economists to use a computer for quantitative research.
The 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 the leontief paradox questioned the validity of the theory 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 empirically rejecting H-O.
developed by Leontief
It has provided a good deal of insight into the foreign trade position of the U.S., but it has hardly helped to establish or refute the H.O. Static theories such as the factor price equalization theorem or the H.O. Theory of comparative advantage should perhaps not primarily be viewed as geared toward empirical testing. They are first and foremost means of studying the general equilibrium characteristics of open economies.
However, Leontief was surprised to discover that US imports were 30% more capital-intensive than US exports. Wassily Leontief, a Russian-born American economist, has made many contributions to the science of economics. Leontief’s industry research contributed to the creation of an input-output analysis, which earned him the Nobel Prize in Economics in 1973. The factor-endowment theory asserts that with specialization and trade there tends to occur an equalization in the relative resource prices of trading partners. Investopedia requires writers to use primary sources to support their work.
W.P. Travis explains the Leontief paradox with the help of U.S. trade policy. He refers to the fact that U.S. trade is highly protected, a fact even more true when Leontief made his study than it is today. When Leontief made his study, most competitive imports considered of crude oil, paper pulp, primary copper and lead, and metallic ores. These products were imported because the U.S. simply could not produce them. According to Travis, U.S. protective trade policies alone, therefore, are sufficient to explain the Leontief paradox.
These include white papers, government data, original reporting, and interviews with industry experts. We also reference original research from other reputable publishers where appropriate.

Throughout his professional life, Leontief promoted the use of quantitative data in economics. Leontief campaigned for broader and deeper developments in the area of quantitative data analysis throughout his career. He was also one of the first economists to use a computer for quantitative research.
Which of the following statements is true of the Leontief paradox?
Leontief made use of 1947 input-output tables related to the U.S. economy. 200 groups of industries were consolidated into 50 sectors, of which 38 traded their products directly on the international market. Leontief should have seen whether or not goods imported into America were capital or labour intensive in the country of origin. L. Tarshis approached the whole problem indirectly by comparing the internal commodity prices in different countries. The study revealed that the price ratio of capital-intensive relative to labour- intensive goods was lower in the United States and higher in other countries.
What is Leontief Paradox Trade Theory
To do this, Leontief broke down the U.S. economy into 500 sectors, establishing one of the first economic sector classification systems. He developed input-output tables for sector analysis that estimated the impact a change in production of a good has on other industries and their inputs—establishing the interdependent relationships of economic sectors. According to Balogh, the Leontief paradox involved a bias that resulted from the aggregation in the input-output matrix for indirect computation of capital-labour ratio. A spurious labour-intensity of the U.S. export industry appeared because of the aggregation of capital-intensive exportable goods with similar domestically used labour-intensive goods. Vernon found that the U.S. export performance is closely related to the investment in research and development.
The conclusion was that the given value of U.S. exports embodied less capital and more labour than would be required to expand domestic output to provide an equivalent amount of competitive imports. Expressed inversely, U.S. import replacement industries required more capital relative to labour than did U.S. export industries. He confirmed Leontief paradox and found that the U.S. import-replacement industries were 27 percent more capital-intensive than the United States export industries. Baldwin pointed out that the exclusion of even natural-resource industries was not enough to repudiate the paradox.
In 2005 Kwok & Yu used an updated methodology to argue for a lower or zero paradox in U.S. trade statistics, though the paradox is still derived in other developed nations. A 1999 survey of the econometric literature by Elhanan Helpman concluded that the paradox persists, but some studies in non-US trade were instead consistent with the H–O theory.

Composite Commodity Theorem
The high labour-intensity in the United States exports and capital-intensity in case of import-replacement products can be attributed to the demand pressures in the United States and her trading partners. Romney Robinson explained Leontief paradox without repudiating the Heckscher-Ohlin theory on the basis of relative patterns of demand existing in the United States and other countries. Leamer in 1980 and 1984, it is suggested that the comparison of K-L ratio in the multi-factor world should be in production versus consumption rather than in exports versus imports. Applying this approach to 1947 Leontief’s data, Learner concluded that K-L ratio was indeed greater in the United States production than the United States consumption. The study made by Stern and Maskus in 1981 for the year 1972 confirmed the H- O theory even when natural resource industries were excluded.

Another criticism is that the paradox assumes a linear relationship between all inputs and outputs; however, there are many cases where this assumption does not hold true. The Leontief paradox is a mathematical puzzle of how to allocate resources. It has been shown that the paradox can be solved by using linear programming techniques and other methods. It affords less protection to home producers during eras of rising prices.
