Applied General Equilibrium Modelling GLOBE, STAGE and R23 Models

CGE Modelling: Course Software


The courses use the General Algebraic Modeling System (GAMS) software. The text editor used is GAMSIDE (included with the GAMS programme) and all data are handled using GAMS Data Exchange (GDX) and MS Excel.

It is not necessary to buy GAMS for these courses; the Practical course only requires the Demo/Student version of GAMS and the GAMS corporation provide (time limited) licences for participants on the other courses offered.

The GAMS software can be download from here. Please ensure you download the correct version for your PC.

We will not use GAMS Studio for the courses in 2020-21, so ensure you choose to install the GAMSIDE version.

(We plan to use GAMS Studio once it has the full functionality needed by the models used in the courses.)

Operating System

The instructions assume you are using a PC with the Windows operating system (v 7 or later) either on a Windows PC or when running Boot Camp on an Apple Mac.

If you are a user of the Apple Mac or LINUX operating systems there are versions of GAMS compatible with those systems; we cannot guarantee the material we provide will always work with the Apple Mac or LINUX operating systems or support these OSs.

(In the future GAMS Studio may help us relax this constraint.)

Microsoft Office

The courses use MS Excel for providing (some) model data and for downloading results data MS Excel is very useful for tabulating and graphing model results. A word processor, e.g., MS Word, will be needed to complete the assignments.


MOODLE is accessed through the internet. During the courses participants will have access to all the course materials (course programme, video presentations, PowerPoint slide shows, various ‘how to’ guides, technical and teaching documents, practical (CGE and other) computer exercises, and  GAMS libraries containing all the GAMS codes and databases used during the course) via the Moodle Cloud site.
