Analyzing Industrial Water Demand in India: An Input Distance Function Approach
نویسنده
چکیده
This study investigates the water demand of Indian manufacturing plants. It adopts an input distance function approach and approximates it by a translog form. Duality between cost function and input distance function is exploited to retrieve information concerning substitutability and the shadow price of water. The model is estimated, using linear programming approach, on a sample of 92 firms over the three years. The results show that the average shadow price of water is rupees 7.21 per kilolitre and the price elasticity of derived demand for water is high, -1.11 on average, a value similar to what has been found by other researchers working on developing countries (for example, China and Brazil). This indicates that water charges may be an effective instrument for water conservation.

متن کاملAn iterative method for forecasting most probable point of stochastic demand
The demand forecasting is essential for all production and non-production systems. However, nowadays there are only few researches on this area. Most of researches somehow benefited from simulation in the conditions of demand uncertainty. But this paper presents an iterative method to find most probable stochastic demand point with normally distributed and independent variables of n-dime...
