STAGE Model Genealogy


The origins of STAGE model derive from the US Department of Agriculture's (USDA) Economic Research Service (ERS) model, which was developed under the leadership of Sherman Robinson (Robinson et al., 1990; Kilkenny, 1991). The STAGE 1 is a ‘simplified’ version of the PROVIDE project model (McDonald, 2003) that was developed as part of research project funded by the South African government; the sample database used in this version is for South Africa. These simplifications were undertaken when the GLOBE model was started so as ensure both model suites had consistent structures and notations.

 

Open source version of STAGE are template models that represent useful starting models for PhD students, and other persons new to single country CGE models, who want a model that provides a basis on which they can build by adding their own behavioural relationships.


There are currently a number of variants of the STAGE model: STAGE 2, STAGE_EN (energy model), STAGE_LAB (enhanced labour market), STAGE_DYN (dynamic model) and other less formal variants developed as parts of various research activities.


The STAGE model is part of a suite of models that include a global model (GLOBE) and a range of teaching models - the SMOD suite. All these models use a (overwhelmingly) common set of notation and formats.


STAGE has been used, inter alia, for studies of South Africa, Brazil, India, Mozambique, Botswana, Ethiopia, Kenya, Ireland.
