1996, July This paper explores trade policy and investment linkages in the GTAP Model. This is done under alternative steady-state closure rules linking trade to consumption, production, and investment, and emphasizing the general equilibrium nature of capital accumulation mechanisms. When...

1998, March In static applied general equilibrium models, the exogenous/endogenous split between variables (or closure) is used to infer the time frame over which the effects of a shock are simulated. This paper introduces a long-run closure for the GTAP Model (Hertel and Tsigas, 1997) and uses...

January 2000 Huff and Hertel (2001) derive a welfare decomposition for the equivalent variation in the GTAP Model. The derivation appears to be very specific to GTAP. Nevertheless, it contains nearly all the ingredients required for performing welfare decomposition for any CGE model. In this...

Bilateral trade flows are reported by both importers and exporters. Large discrepancies in reported import/export trade flows can be found when these two reports are compared. The GTAP Data Base requires consistency between the export flow and its corresponding import flow for all partner pairs....

Note added March 2002 The methods described in the paper below have been automated as part of Release 8.0 of GEMPACK. This new version of GEMPACK (which is being beta tested by several modellers now and will be officially released later in 2002) makes it very easy to implement quotas (including...

This paper reports a method for converting versions 5 and 6 of the GTAP Data Base into a global SAM that is stored in both the GAMS data exchange (GDX) and Header Array (HAR) formats. The focus of attention is on the generation of a SAM representation of the GTAP Data Base that is fully...

This paper describes a procedure designed for incorporating improved information on taxes into existing GTAP data aggregations. The aim of this procedure is to maintain the internal consistency of the data base while minimizing the impacts of the tax change on the value flows in the data base....

1996, October This technical paper documents one approach to incorporating monopolistic competition into the GTAP Model. In this framework, consumer preferences are heterogeneous, leading to an apparent "love of variety" in the aggregate utility function for each region. The more heterogeneous...

This paper describes how the standard GTAP framework may be used to assess the short-run impacts of changes in international capital market conditions. It describes a technique that can be used to examine the short-run effects of changes in country risk. In the standard GTAP Model investment...

Computable general equilibrium (CGE) models have been heavily utilized in analyses of the costs of Greenhouse Gas mitigation policies. This is in large part due to their ability to simulate potential impacts of prospective economic policies taking into inter-sectoral and international...
