        The aim of this paper is to assess the demand function of municipal water for of Golestan province by adopting a pooling data model during 1999-2011 to determine the minimum requirement of water quite necessary for livelihood. The results indicate that the price elasticity of demand is -0/26, income elasticity of demand is 0/00095 and cross elasticity of demand is -0/2. Therefore, water is an essential and complementary commodity. The minimum requirement of water is 687 liters daily. Manuscript profile

        In this paper, the effect of subsidy on the long run urban water demand function has been examined in the city of Qom. To do this, the researchers have used monthly time series data during 2008:01-2011:06. The model estimated is based on the maximization of Stone - Gery More
        In this paper, the effect of subsidy on the long run urban water demand function has been examined in the city of Qom. To do this, the researchers have used monthly time series data during 2008:01-2011:06. The model estimated is based on the maximization of Stone - Gery utility function, autoregressive and co-integrated model approaches. The results indicate that the decrease or removal of water subsidy would decrease urban water demand. Also, Qom urban water demand has a negative relation to the price of water and other commodities and has a positive one to the revenue. All of these relationships are completely in line with economic theories. The province urban water demand is inelastic to water and other commodities prices and so a necessity for revenue. Also, the minimum level of water consumption of the households, when removing the price subsidy, is 38 liters per day. Manuscript profile

        In this study, the aim is to identify the economic and welfare effects of forming the water market in the Varamin region. Changes in the area under aquaculture, gross profit in two situations (water market and lack of water market) during 2011-2016 were calculated and compared using GAMS software and positive mathematical programming model. The results show that the establishment of the water market would have a positive and incremental effect on the gross profit of farmers in the region. Also, Cultivation of crops such as wheat, rice, barley, cucumber and potatoes, tomatoes and garlic has been more profitable and more crops can be planted. Based on the results, it is suggested that the government provide private-sector participation through investment and financial incentives. Manuscript profile
