Models Implemented and Solved using GEMPACK

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 MONASH 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 MONASH, MONASH-USA, 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 RunMONASH.
  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.
