Normalizing VES production functions: extending the supply-side system approach
将Klump等人(2007)的标准化方法扩展到可变替代弹性(VES)生产函数，解决识别问题，实现替代弹性和要素增强型技术变革的联合估计，并连接CES与更灵活的VES模型。
This paper extends the Klump et al. (2007) normalization procedure to Variable Elasticity of Substitution (VES) production functions. Normalization addresses identification issues in VES model estimation, allowing joint estimation of substitution elasticities and factor-augmenting technical change, while offering a tractable extension of the normalized supply-side system that bridges the gap between CES and more flexible VES specifications.
