  • Land Use in Computable General Equilibrium Models
    Land Use in Computable General Equilibrium Models
    Taheripour, Farzad ;
    Zhao, Xin
    2020-02-01 | PDF
    Constant Elasticity of Transformation (CET) functions are widely used to allocate land across uses in Computable General Equilibrium (CGE) models. These models fail to maintain the physical area of land in balance. This paper examines this issue. It shows that heterogeneity in land prices (rents) is the main source of imbalance in land area, not th ...
