With the basic knowledge of different marketing system in Myanmar and Japan, this study forcuses on the empirical test to find out the number of distributed lags the retail price had, from wholesale price for some selected vegetabkes. Using monthly data for three years(2001-2003), The Almon Distributed Lag Model,introduced by Shirlay Lamon(1965), was applied in order to verify the number of lags in Myanmar and Japan. Following the introduction anout the marketing behavior in both countries, the methodological framework, results, and discussions with some concluding remarks were conducted in this paper. The results evidenced that there was a lag from wholesale to retals price in Myanmar for all crops. However, in Japan, there was no lag for very perishable crops like tomato and cabbage, but with a lag for less perishable crops of potato and onion. The lags of price responses for very perishable crops in Myanmar showed the weakness of price formation pricess due to inefficient marketing system. It has been suggested that the efficiently in Myanmer can be improved by 1) increasing the volume of business; 2) introducing in wholesale markets with effective laws; 3) upgrading modern retailing system; and 4) facilitating the construction of information, infrastructure and transportation systems.
