Water demand<br />management has been a concern of economic planners as a new approach in environmental<br />economics. This study aims to investigate water demand management in different product<br />markets in downstream of Yengejeh Dam in Neyshabur. This is an exploratory study in<br />nature which was conducted through a questionnaire survey in 2015-2016. The population<br />of this research is composed of all farmers who use water from Yengejeh Dam to irrigate<br />their lands. Using Cochran formula at the level of 6% error, 139 farmers were selected as<br />the sample of this research randomly. A scenario of increasing the elasticity of product<br />demand in resource allocation in the competitive and monopolar water market was<br />developed by assimilation algorithm in the studied region. According to the market<br />situation of water in the region which is almost similar to monopolar water market, the<br />results suggest that if barley farmers replace cultivation of this crop and orient towards<br />exported products instead, the amount of product is reduced and farmers increase their yield<br />per hectare of land while using more water supply and more area under cultivation. https://ijerr.gau.ac.ir/article_3705_78cc402f195c2ddf639660179b52171e.pdf
