...l explains how the variations of the price or quantity of one factor can have an influence upon the other. For example if the quantity of land suddenly varies this will have little effect upon cloth who is more labour intensive, on the other hand food who is more land intensive will probably have an important price and wage variation ; therefor it is possible to assume that there is an important correlation between the rent of land and the wages of labour, and there is also correlation between the price of food and the price cloth (as illustrated beneath). Depending on these ratios a country can determine in what kind of sector it has a comparative advantage. This is due to the Input possibilities in food production fact that changes in the different factors affect the different sectors in a disproportionate manner advantaging one and disadvantaging the other. If this nation comes to open to trade with another nation, this will lead to factor price convergence, the workforce involved in the countries most abundant factor gain , whereas on the other hand the owners of the countries most scarce resource will probably lose from trade, there are though, important suppositions, both countries produce both goods, technologies are the same, no barriers to trade. Thus trade equalises the relative price of all factors, this is because trade is but a mask, for countries through food and cloth are in fact trading factor endowments and labour. The US which is the country in the world with the most capital per unit of labour, and thus has a comparative advantage in capital intensive goods. Applying the H-O model to the US should reveal that it exports capital intensive goods. However Leontief studied US exports for the 25 years following World War2, and revealed that US imports were consistently more capital intensive than it’s exports which goes against all the conclusions of the H-O model. The study also outlined the fact that US exports were more skill intensive. This study shatters all the assumptions of the H-O theory because the US is one of the most liberal nations, and one whose sheer economic size means that if it is not possible to include it in the H-O theory, how much is the H-O really worth? Since then many have addressed the issue but even there studies are confusing however some seem to be pointing in the right direction. First of all it seems that economists have wrongly been considering the nature of what can be considered as a factor in the H-O model. The factors considered should be immobile in the sense that this combination of factors (in those specific proportions and quantities), is unique to this particular nation(i.e. natural resources and labour). However many economists have considered capital as being one of those factor inputs. But capital nowadays is something that can travel more freely than ever. This is largely due to the fact that many free trade areas have been created (EU, NAFTA…), and the appearance of big trans-national companies that can easily move large sums of capital to a subsidiary branch in another nation. Another assumption that greatly hinders the H-O model of trade is the fact that it assumes that technology is the same everywhere and even though machines can be bought it can be argued that technology is relatively immobile, thus creating greater differences in the needs of firms to operate with skill or unskilled labour. Another problem is how the different sectors have evolved ; the primary sector depends much more upon natural resource allocation than any other sector. Natural resources are truly immobile and specific to a country thus the H-O model applies quite well to patterns of trade applied to primary goods. On the other hand it is more complicated to compare and set a pattern of inter-sector trade because of the difference between the nature of primary agricultural goods (traded by the south) and industrial goods (traded by the north). This is because agricultural goods prices have a tendency to fall or increase relatively slowly compared to the price of industrial goods who increase rapidly. Thus the...
