The structure of the FTAP model

Research memorandum

This research memorandum by Hanslow, K., Phamduc, T. and Verikios, G., was released originally in December 1999, in conjunction with the model software. This version of FTAP was version 1. The current version of FTAP, released on 8 January 2001 is version 2. The documentation up to appendix I describes FTAP version 1. Appendix J describes changes made to FTAP in subsequent versions. Changes made to the version 1 documentation affect chapters 3 and 4.

The FTAP model is a comparative static, computable general equilibrium model of the world economy that includes a treatment of foreign direct investment on a bilateral basis. The FTAP model was developed in stages from the GTAP model, with the addition of the structure necessary to support the analysis of services liberalisation. A major component of this liberalisation is the removal of barriers to FDI in the tertiary sector.

This research memorandum documents the equations of the FTAP model and is intended to provide self-contained documentation for the FTAP equation system.
