This paper aims to give a better understanding of demand for information of production and market in rural areas of the Mekong Delta. The results from the survey of three selected provinces reveal that most rural people have needs for information in terms of input and output markets such as variety, fertilizer, pesticide, farming techniques and so on. However, their need for information was not satisfied fully regarding accuracy of information, and frequency of information supply. Besides, the survey indicated that most rural people have mainly gathered information they need from TV and radio programs on agricultural extension; while searching for information from the Internet was too difficult in most rural areas currently due to high cost of connection, weak network, and low educational standard, etc. In sum, the information about production and market not only contributes to farming efficiency by farmers, but also partly upgrades an awareness of farmers of the process of applying modern technologies

This paper examines the causal relationship between stock prices and trading volume for the Ha Noi Stock Trading Center over the period from Feb. 6th 2006 to Feb. 27th 2009. To investigate the causal relations between stock prices and trade volume, the Granger causality test is applied in this study. Main results derived from the test reveal that there is the uni-directional causality between the daily market index and trading volume. In other words, changes in the market index lead to changes in market trading volume, but daily market trading volume does not cause the market index to change.
