Price Formation of the Marine Products Landed at Plural Ports:On the Case of Samma

Abstract

In this paper, focusing on samma, we analyze the price formation of the marine products landed at plural ports, with attention to the relationship of them.　As a result, it is revealed that the monthly price at landing port depends not only on the current amount of quantities, but also on the past price, the expected amount of quantities throughout the fishing season, the current quantity at the port, and the distance between the port and the city.　That is, among the plural markets, there are connections not only of the amount, but also of the temporal and the spatial.　On the analysis of the fishery resource management problem among the plural economic organizations in one country, we should consider the market externalities with regarding that there is close connection like this between the markets supplied by the plural economic organizations.

The aim of this paper is to reveal the structure of the price formation behind the market externality, without direct analysis of the market externality itself.　But, the contents of this paper provide not only the base of the analysis of the market externality, but also the feasibility of the empirical analyses about the fishery resource management among the plural economic organizations, by revealing the structure of the price formation quantitatively.
