The main objective of this paper is to study the differential impacts of various irrigation water pricing policies. The methodology used is based upon Multi-Attribute Utility Theory (MAUT) mathematical programming models and also simulation. Two kinds of data needed to feed the models were obtained from official records and surveying. The analysis of water pricing policy indicates that the most...
introduction: nowadays, efficient use of scarce water resources is one of the government’s importantgoals for dealing sustainable development in the agricultural sector. in addition to optimal exploitation and using of surface and groundwater resources, choosing of efficient types of irrigation technologies is a very important factor in sustainable water resource management. this study tries to...
An econometric analysis of Hong Kong’s monthly per capita water usage for the 25-year period of April 1985 through March 2010 reveals that per capita usage is insensitive to price but dependent upon past usage, per capita income, weather, and seasonal factors, with rising income countering what would otherwise be a downward trend. Given Hong Kong’s current inflationary environment and large gov...
abstract water pricing is a policy instrument for improving water efficiency, reducing water demand, management of the irrigation systems and recovering costs. the underlying principle of water pricing is that it should reflect the opportunity cost of water. in this study, parametric mathematical programming approache were used to estimate the willingness of farmers to pay for groundwater under...
[1] European water policy requires all EU Member States to implement volumetric water pricing at rates that roughly cover the total costs of providing water services. The objective of this paper is to develop a methodology that will enable us to analyze the differential impact that a water pricing policy for irrigation would have on heterogeneous farmers of an irrigated area. For this purpose, ...
The aim of this paper is to consider the effects of monetary policy on production and prices through asset price channel (the housing price index) in Iran during 1368Q1 to 1387Q4. By Vector Error Correction (VEC) Model, the effect of monetary policy has been considered through this channel. In general, the results show that the debt of banks to the central bank as instruments of monetary policy...
in this study, to determine the economic value of irrigation water and simulate the response of farmers to reducing available water policy of positive mathematical programming models (pmp) was used. by the proposed model, the economic value (shadow price) of irrigation water estimated in each of the areas of western rodbar alamuot, rajai dasht and eastern rodbar almuot. then, the reactions of ...
Dominance of arid and semiarid climate in a vast area of Iran along with the water consumption growth necessitates a more sophisticated planning, a more efficient operation towards an optimal allocation and conservation of water resources in the country. In recent decades many countries, including Iran, have adopted increasing block tariffs for domestic water management. This policy is based on...
This paper aims to determine the impact of dividend policy on stock price volatility by taking firms listed on Tehran stock exchange. A sample of 68 listed companies from Tehran stock exchange is examined for a period from 2001 to 2012. The estimation is based on cross-sectional ordinary least square regression analysis to find the relationship between share price volatility and dividend poli...
