Abstract:  

Public pricing of products is one of the most important economical issues, since any changes in the pricing, affects both the welfare of consumers and quantity of goods and Services which are produced.

In this paper which is done for natural gas pricing in Iran, the purpose is giving a price that the government can consider it as a suitable choice for using in subsidies targeting project. These prices have two advantages: first, they try to maximum the social economical welfare (summation of producer and consumer surplus) second, this method solve the problem that the producer has in covering their costs (by marginal cost pricing) because of increasing returns to scale.

This paper deals with the optimal gas pricing in industrial sector in Iran by the Ramsey method of pricing. In this regard we have used fuzzy regression (because of its accuracy and devoid of classic regression restrictions) and the available data from 1356 to 1390 for estimating production function and returns to scale in natural gas production side. Also for estimating demand function and elasticity we have used Auto Regressive Distributed Lag Method(ARDL) and the data from 1350 to 1389. The results show that the current prices aren’t optimum and despite implementation of subsidies targeting project the prices are low.
