本文研究了在可计算一般均衡（CGE）模型的标准分层KLEM生产函数的规范中施加不同可分性假设的影响。在生产函数中引入能量的适当方法多年来一直是争论的来源。然而，虽然建模者经常对与输入之间替代弹性相关的值进行参数敏感性分析，但很少对生产函数的结构进行测试。然而，所选择的结构反映了建模者对不同输入之间弹性的看法，并将在相对价格发生变化时对模型结果产生影响。我们通过在关于KLEM生产函数的结构和其中的可分离性假设的不同假设下，向苏格兰经济的CGE模型（针对能源供应部门）引入简单的需求冲击来说明我们的论点。
This paper examines the impact of imposing different separability assumptions in the specifications of the standard hierarchical KLEM production function in a computable general equilibrium (CGE) model. The appropriate means of introducing energy to production functions has been a source of debate for a number of years. However, while modellers often subject results to parametric sensitivy analysis regarding the values associated with elasticities of substitution between inputs, it is rarely the case that the structure of the production function is subjected to testing. However, the chosen structure reflects the modeller's view about elasticity between different inputs and will have implications for model results wherever there are changes in relative prices. We illustrate our argument by introducing a simple demand shock to a CGE model of the Scottish economy (targeted at the energy supply sector) under different assumptions regarding the structure of the KLEM production function and separability assumptions therein.
