The Site


This site provides access to technical documentation and (GAMS) code for a range on applied general equilibrium models and associated code for data handling, miscellaneous teaching materials and working papers.


All the teaching materials provided on this site are provided free of charge for academic and training purposes: we appreciate  feedback.


All the codes for the STAGE and GLOBE models are open source subject to the Creative Commons BY-NC-SA (Attribution - Non Commercial - Share Alike) licence, i.e., free of charge for academic use.


It is hoped, however unrealistically, that those who use these codes for material gain, through consultancy and/or contract research, will make a contribution of 1.0% of gross staff costs from the project to Oxfam.


PLEASE read Conditions of Use carefully before using any of this material.

The Models


The two suites of models available from this site are descendants of the models associated with the work of Dervis, de Melo and Robinson (1982). More specifically both suites of models are developments of the US Dept of Agriculture’s single country CGE model from 1990 (Robinson, et al., 1990; Kilkenny, 1991).


GLOBE is a suite of global/multi region CGE models calibrated using data from the GTAP database. While these models use the GTAP database they include a series of different behavioural assumptions in comparison to the GTAP model and use a transformation of the standard GTAP Social Accounting Matrix (SAM).


STAGE is a suite of single country CGE models that require a country specific CGE model for its calibration.


R23 is a global development of the  well-known 123 model.


The codes made publicly available are for ‘standard’ variants of each model suite. These versions are robust (relatively) formulations. We are confident that persons with substantial GAMS experience can easily use these models.


Technical documentation for variants of the models is also provided.
