Abstract
In this Study, We applied Translog cost function with four Input (Labor, Capital, Energy and Material) and ISUR[1]method for analysis of the cost structure of 11 most Energy intensive sub sector industries (With 4 Digit ISIC[2]code) of Manufacture of other Non-Metallic Mineral Products (Code26) and Manufacture ...

In this Study, We applied Translog cost function with four Input (Labor, Capital, Energy and Material) and ISUR[1]method for analysis of the cost structure of 11 most Energy intensive sub sector industries (With 4 Digit ISIC[2]code) of Manufacture of other Non-Metallic Mineral Products (Code26) and Manufacture of Basic Metals (Code 27) during the period 1375-87. Input Share, Economies of Scale, Minimum Efficient Scale, Own-cross price elasticity and Morishima elasticity of substitution were calculated. The important results of this study is the detection of Scale effects, which reveals possibilities for increasing Scales (products) and reducing costs. The result of Cross-price and Morishima Elasticity of substitution shows that all Input substitution elasticities areElastic. This case indicates that the Firm's Manager of Energy intensive industries have a lot of options to substitute one input for the other inputs.
