STAGE Model Genealogy
The STAGE model was derived from the PROVIDE models, which was itself derived from the USDA’s ERS model, (Robinson et al., 1990; Kilkenny, 1991) and Dervis, de Melo and Robinson (1982) .
The STAGE model consolidates many of the behavioural relationships included in the variants of STAGE into a single model designed to be used in either comparative static or recursive dynamic models. STAGE is compliant with the accounting conventions and price relationships in the System of National Accounts (SNA) and the System of Environmental-Economic Accounts (SEEA). The model is calibrated with transactions data presented in SAM format together with series of satellite accounts, e.g., labour quantities, energy quantities and emissions, water quantities, etc.
The STAGE model includes the following features: generalised nesting for production and utility functions; flexible macroeconomic closure and (factor) market clearing conditions; endogenous factor supplies by institutions; flexible exchange rates; factor mobility functions; air pollution and emissions tracking; generalised nesting of CES functions for imports and CET functions for exports; etc.
STAGE and variants has been used, inter alia, for studies of South Africa, Brazil, India, Mozambique, Botswana, Ethiopia, Bhutan, Senegal, Kenya, Ireland, West Bank.
The STAGE models are part of a suite of models that include a global country model, ANARRES, (a development of the GLOBE model), the R23 model and the SMOD suite. All models use a common set of notation and formats.
The open source version of STAGE is a good template model for PhD students, and persons new to CGE models, who want a model that provides a base on which they can build their own behavioural relationships.
Variants of the STAGE model can be produced for clients. Email firstname.lastname@example.org to discuss licensing and model variant options.
