GEMPACK software is used in over 400 organizations around the world (universities, government departments and private sector firms) to implement
and solve a number of economic models including:
several single-country models (of which the ORANI and descendant models of the Australian economy are perhaps the best-known),
multi-country trade models, of which GTAP developed by the Global
Trade Analysis Project (Purdue University, Director: Thomas W. Hertel) is perhaps best known,
regional models, such as the MMRF and TERM models,
intertemporal (or dynamic) models (with forward-looking behaviour), and
recursive dynamic models such as
USAGE, ORANIG-RD and GTAP-Dyn (the dynamic version of GTAP).
Example models supplied with GEMPACK include
small teaching models (Stylized Johansen, Miniature ORANI),
multicountry trade models (TRADMOD, GTAP),
single-country models DMR (Korea) and ORANIG (Australia and many other countries), and
small intertemporal models (TREES, CRTS and 5SECT).
Example models available from the GEMPACK web site include
The recursive, dynamic version ORANIG-RD of ORANI-G. This can be used with the Demonstration Version of RunDynam.
The recursive, dynamic MONASH Model of Australia. This can be used with the Demonstration Version of RunDynam.
You can replicate the main application in the MONASH Model book.
A fully intertemporal, rational expectations version ORANI-INT of ORANI.
You can replicate the applications in Michael Malakellis's Springer book.
Many more examples of GEMPACK applications can be found in The CoPS Archive.
