Wide-range estimation of various substitution elasticities for CES
Hence, the Energy Efficient Constant Elasticity of Substitution (EE-CES) production function is proposed to model the aggregate production process in Nigeria while taking energy-use as a capital-dependent input factor. The Indirect Least Square (ILS) results show a 19% actual capital energy-efficient level in Nigeria.
