Ohlin's name lives on in one of the standard mathematical model of international free trade, the Heckscher-Ohlin model, which he developed together with Eli Heckscher. He was jointly awarded the Nobel Memorial Prize in Economic Sciences in 1977 together with the British economist James Meade "for their pathbreaking contribution to the theory of international trade and international capital movements".
In 1930 Ohlin succeeded Eli Heckscher, his teacher, as a professor of economics, at the Stockholm School of Economics. In 1933 Olin published a work that made him world renowned, Interregional and International Trade. In this Ohlin built an economic theory of international trade from earlier work by Heckscher and his own doctoral thesis. It is now known as the Heckscher-Ohlin model, one of the standard model economists use to debate trade theory.
The model was a break-through because it showed how comparative advantage might relate to general features of a country's capital and labour, and how these features might change through time. The model provided a basis for later work on the effects of protection on real wages, and has been fruitful in producing predictions and analysis; Ohlin himself used the model to derive the Heckscher-Ohlin theorem, that nations would specialize in industries most able to utilize their mix of national resources efficiently. Today, the theory has been largely disproved, yet it is still a useful framework by which to understand international trade.
Ohlin was party leader of the liberal Liberal People's Party from 1944 to 1967, the main opposition party to the Social Democrat Governments of the era, and from '44 to '45 was minister of commerce in the wartime government. His daughter Anne Wibble, representing the same party, served as Minister of Finance in 1991-1994.
The following conditions must be true:
The theory does not depend on total amounts of capital or labor, but on the amounts per worker. This allows small countries to trade with large countries by specializing in production of products that use the factors which are more available than its trading partner. The key assumption is that capital and labor are not available in the same proportions in the two countries. That leads to specialization, which in turn benefits the country’s economic welfare. The greater the difference between the two countries, the greater the gain from specialization.
Wassily Leontief made a study of the theory that seemed to invalidate it. He noted that the United States had a lot of capital; therefore, it should export capital-intensive products and import labor-intensive products. Instead, he found that it exported products that used more labor than the products it imported. This finding is known as the Leontief paradox.
