Applied General Equilibrium Modelling ANNARES, STAGE and R23 Models

© Scott McDonald


ANARRES t is a ‘standard’ global CGE model designed for use in the Global and Recursive Dynamic (global) training courses.

It is a development of the ANARRES_1 model, which includes additional behaviours and features: it is calibrated using data derived from the GTAP database augmented by data for international current account transactions.

The underlying approach to multi-region modelling for this CGE model is the construction of a series of single country CGE models that are linked through their trading relationships. Consequently each region in the model has its own numéraire price and a nominal exchange rate, while the model as a whole requires a numéraire. As such this model contains a fundamentally different philosophical approach to global modelling to that found in the large majority of models that use the GTAP.

Trade is modelled using nested CES (imports) and CET (exports) functions with an adaptation to mitigate the impacts of small trade shares. Production is modelled using nested CES functions. The tax instruments are those in GTAP plus direct (income) taxes on the households who also save.

A distinctive feature of the model is the use of a 'dummy' region, known as GILD, that allows for the recording of inter regional transactions where either the source or destination are not identified. The GILD construct provides a general method for dealing with any transactions data where full bilateral information are missing.

ANARRES_t evolves as the needs of our training programmes evolve. The documentation available here reflects, as accurately as we can, the state of the model on the date on the front page of the technical document; it is often out of date.

The codes for ANARRES_t are only supplied to participants of cgemod training courses.
