Le comportement des groupes dans la vie économique internationale

[eng] SUMMARY The pure theory of international trade has been for nearly 150 years steadily growing up thanlks to widening of the conditions laid down by Ricardo However the author believes that the concept of national gain from international trade is too obscure and cannot pretend to rea listic explanation of the facts The division of gain has been generally studied by distinguishing the traditionnal factors of production It does not appear that thia approach has been fruitful It seems preferable to start from the concept of economic groups This paper tries to define these and to give classification each group has its own interests and attitude on such questions of international trade as protectionnism exchange rate policy and economic unions They trie to influence the economic policy of their national State or even of foreign States Many examples are taken from recent facts and show that the division of the gain from trade is the result of great number of confron tations not always pacific where coercition plays very important role Practically the groups and their governments trie to maximise the eco nomic welfare as it is understood by the dominant groups
