International trade has been one of the major factors in determining the success of a particular region in the world. It has definitely come a long way from the ancient times. With the advent of technology all around the globe, the International trade too developed to a large extent. The basic idea that is related with International trade actually involves the exchange of goods and services across the international territories. With the passage of time, International trade came to acquire many complications as a result of which International trade theory too came into existence. The basic idea that is associated with International trade theory is that it actually it monitors the trade patterns among different regions in the world. International trade theory also analyzes the effects of the trade patterns and the policies across the globe.
There are several models that are proposed by the International trade theory. Take a look at the proposed models, these are,Ricardian model, Heckscher-Ohlin model, New Trade Theory and
Gravity model of trade
The Ricardian model is one of the significant contributor to the concepts of International trade theory. The main focus of this theory is on the advantage of being able to compare the statistics all over he world. The Ricardian model puts forth the theory that the countries around the world are capable of producing the bes what they can. Quite different from other models of the theory of International trade,
the frame work of this particular model suggests the and predicts that the countries will completely specialize instead of producing a variety of goods that is is not confident to produce. The factors like relative labor amounts and capital within the country are not directly considered by this particular theory.
The Heckscher-Ohlin model came into existence as an alternative to the Ricardian model of fundamental comparative advantage. The model has greater complexity but did not account for accuracy with the kind of predictions that was put forth by the model. However it needs to be mentioned that the theory did provide a solution by the including the price mechanism into the International trade theory. But this solution can be considered only from the theoretical point of view.
New Trade Theory provides many trade facts accompanied with several explanations. This particular theory is quite successful in analyzing certain facts of trade that could not be justified by the above mentioned models. This includes the fact that most trade that takes place between the companies involves levels of productivity and large amounts of multinational production as well.
The Gravity model of trade presents a picture of empirical analysis of several trading patterns instead of following rigorous theory models. The gravity model predicts trade between countries and also focuses on the interaction of economic size of the country.
