Student, Agricultural Economics, University of Ardakan Journal Article 2017 02 11 Agricultural products market is an interval market, where producers and consumers have been distributed at different places. The aim of this study was to analyze the one price law through evaluating the continuity and the type of coherence in the market of 2 depicted agricultural products (saffron and bean) at 12 important provinces of our country (Mazandaran, Gilan, Golestan, Tehran, West Azerbaijan, East Azerbaijan, Semnan, Khorasan Razavi, Isfahan, Fars, Kerman, Khoozestan) which represented the entire of Iran. In this study, the monthly price index logarithm for a 9-year period (1384-92) was used. To estimate the amount of continuity, the Johansson’ co-integration method in vector error correction model (VECM) and Eviews software was applied. The results showed that the complete integration of the markets in the long run was rejected in the market of all 2 agricultural products and the hypothesis of the existence of one rice law among all the markets was not proven. In case of some products, some of the provinces were the governors of the price. According to the results and in order to increase the continuity of the markets, it is suggested to form production and distribution of the products cooperatives and also to develop the facilities and the underlying services.
