The Models


LICENSING


The models are SAM based models. The models here depend on the data and price systems developed by Richard Stone and associates.


The models are descendants of the USDA’s single country CGE model from 1990 (Robinson, et al., 1990; Kilkenny, 1991), which are developments of Dervis, de Melo and Robinson (1982).


GLOBE is a suite of global/multi region CGE models calibrated using data from the GTAP and/or WIOD databases presented as global SAMs.


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


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


The codes for these versions are robust formulations. Persons with good economics and GAMS experience should be able to use these models.


Technical documentation for variants of the models is also provided.

‘Black Boxes’

CGE models are NOT ‘black boxes’. Given an understanding of general equilibrium (GE) microeconomics, and some macroeconomics, and the ability to read a simple programming language, all model insights are ultimately obvious. GE systems may be complex, just as the world is complex; but an unwillingness to learn enough economics and a ‘language’ does not make a CGE model a ‘black box’.
