"GTAP Model Version 4.1"
by Hertel, Thomas

The latest version of GTAP.TAB (Version 4.1, November 1998) includes a parameter which captures intermediate input substitution. Users can now specify which endowment factors are sluggish or mobile through the use of a binary switch parameter. The introduction of these new features in the GTAP.TAB file presents some incompatibility with previous set and parameter files. Software for converting set and parameter files for use with the lastest version of the model may also be downloaded.

Changes from v.4.0 to v.4.1
  1. Switch for changing sluggish endowments via parameter file

    This was merely technical issue and did not affect the structure of the GTAP model. In the v.4.0 the SET file was used to define which endowments are sluggish. Introduction of a binary parameter "SLUG" offers a facility to users to switch an endowment from sluggish to mobile by choosing value of zero or one in the parameter file.

  2. Intermediate input substitution

    A non-zero elasticity of substitution between intermediate and value-added (ESUBT) was introduced to generalize the GTAP model. This modification allowed the model to account for the substitution at the top nest of composite production structure, at where the ratio of intermediate inputs and value-added components were used to be fixed in the v.4.0. GTAP model.
