Partial equilibrium models
The GSIM model: <--This link includes all files and documentation. GSIMv2: A non-linear, 35 region spreadsheet version of the GSIM model augmented to include sector-level employment effects and price undertakings, in addition to trade taxes and subsidies and domestic production subsidies. There is also a short background paper. ● GSIMv2.XLS (a 35 region nonlinearized implementation inclusive of optional employment estimates) GSIMv1: The original GSIMv1 (Global SIMulation model) that was developed for the World Bank’s WITS package for tariff and trade analysis, along with a short background technical paper from Francois and Hall (2002). This is a global, multi-region, partial-equilibrium model. If you are using this for teaching, I recommend starting with the GSIM4x4 version of GSIMv1, and not GSIMv2. ● GSIM4x4.XLS (a compact example model with up to 4 regions, and only import tariffs) ● GSIM25x25.XLS (a large template, for up to 25 regions, with tariffs, export taxes/subsidies, and production subsidies).

Anti-Dumping &tc: The USITC’s set of COMPAS models (including some documentation on the spreadsheet).

The Large Model: a multi-region, MPSGE-based model used while I was at the GATT/WTO to assess the Uruguay Round agreements. This model is SAM-based (our global SAM is included). This was published, in various forms: Francois, J.F., B. McDonald, and H. Nordstrom (1993), “An Analysis of the Proposed Uruguay Round Agreement, with Particular Emphasis on Aspects of Interest to Developing Economies, contributor, MTN Negotiations --Uruguay Round background paper, GATT: Geneva, November.

Nordstrom (1995), " Assessing the Uruguay Round," in The Uruguay Round and the Developing Economies, edited by W. Martin and L.A. Winters, Washington: World Bank (discussion paper number 307). This includes a number of features that were innovative for CGE models once upon a time: (1) explicit quotas (included in the file), (2) global monopolistic competition (included in other models available here), and (3) steady-state investment effects (included in the file, and called “numeric ballistics” by Glenn Harrison when he first commented somewhat unkindly on this back in 1993 :) .

The SIMPLE model: This is a somewhat self-contained (i.e. executable) and rather old modified version of the GTAP model. It includes modifications I made in the early 1990s to introduce scale economies, imperfect competition, nested- and non-nested import demand, rigid wages, and some capital mobility treatement to what was then the standard model. Many of these features are actually incorporated in the standard model now, or are available as add-ins elsewhere on this page. This set of links is really here for historical completeness. The idea of the examples was to follow a single experiment across different model features. HTML-based documentation is available. These examples are built on the same dataset as the “Small” model in GAMS/MPSGE linked above.	GEMPACK	GE	MR
Multi-region Doha Round Model : This is a self-contained (i.e. executable) archive of the model used for "Trade Liberalization in the Doha Round," Economic Policy 2005. This is implements monopolistic competition and investment effects as well as TRQs within the framework of the current (as of 2006) GTAP model. The technical annex for the model is available as well.
