The main purpose of this paper is to investigate the informational role of distributors and importers in the international oligopolistic market. This paper is intended as a synthesis of the Economics of International Imperfect Competition and the Economics of Distribution System.When we analyze modern society from the viewpoint of Regional Economics (or International Economics), we should consider the world in which not only producers and consumers exist but also intermediaries enter among them. Intermediaries carry out activities such as the transportation of goods among areas (or among countries) and the information gathering.The conventional economic models analyze only the relation among producers and consumers, without paying due attention to the working and performance of intermediaries. In reality, however, intermediaries such as “the distributor” and “the importer” exist and play an important part.We work with a Stackelberg-type model under uncertainty in which producers play the role of leaders and distributors and importers act as followers. By comparing the five types of information structures, it is shown that information may be detrimental, that improved information for one firm may or may not benefit the other firm and the consumer.In conclusion, this paper clearly shows that the information sharing between the distributor and the importer is more efficient than the information transmission from them to the producer.
