Introduction to HOV

The HO model was made in order to recognize the pattern of trade between many the countries. In this model it has given an overview that goods which are produced in abundant ant will be exported and goods which are produced in scare will be imported using cheap factor of production

Vanek saw international trading of good in an indirect manner that is goods are trade with other countries without other country being aware about the imported factor services within the trading basket. For example when Chinese goods are imported, in result China laborers and capital equipment’s under the modification (i.e indirectly) of imports are entering the United States of America. It was be easy to say that indirect export services has been given to United States of America.

There were many economist who countered HOV that is Choi where he noted that production vector is difficult to forecast as when number of goods are more than factors of production used. Historical study has stated that number of goods outnumber number of factors.

Leamer (1984) gave a answer to the above problem by telling that a country will assign resources among industries to exploit the total value of outputs, within his model, randomly output prices(which are fixed) are determined in the world market. This model permits non negative output solitary in m sectors, and the residual n minus m sectors yield (0) zero output. After carefully watching this Choi countered that as well saying that this cannot be a real world solution because n which is number of industries always have positive output levels.

As a result, (HOV) Theorem, which forecasts the factor content of trade, becomes more applicable. Even though trade path is unknown, when factor price are equalized (FPE), the factor content of trade is exclusive.

Let A denote income share for a country, that would be as shown below.,

A = C/Cw,

As shown above C and C* is nothing but the incomes earned for the home and foreign country, separately. (Provided trade is not balanced then C and C* must mean expenditures to forecast actual trade.)Cw is the income earned by the whole world.

Provided factor price equalization, the home country has abundance in labor if

L/Lw > A

Country’s export services will be (0)zero if the labor endowment would be Lo = A Lw, but positive if L > Lo. Therefore within H-O-V model, the forecasted amount of labor exported in a disguise was that would be indirectly is

ELt = L –A Lw,
