The Global Trade Analysis Project (GTAP) is a research program initiated in 1992 to provide the economic research community with a global economic dataset for use in the quantitative analyses of international economic issues. The Project’s objectives include the provision of a documented, publicly available, global, general equilibrium data base, and to conduct seminars on a regular basis to in...

Although CGE models have received heavy usage, they are often criticized as being insufficiently validated. Key parameters are often not econometrically estimated, and the performance of the model as a whole is rarely checked against historical outcomes. As a consequence, questions frequently arise as to how much faith one can put in CGE results. In this paper, we employ a novel approach to the...

A The making of projections often requires an economy-wide perspective, and the estimation of consumer demands at the international level. In this paper, an implicit, directly additive demand system (AIDADS) is estimated using cross-country data on consumer expenditures from two different sources: the International Comparison Programme (ICP), and the Global Trade Analysis Project (GTAP)....

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 this closure to simulate and compare the short-run and long-run effects of Asia-Pacific trade liberalisation. The...

The paper documents the energy-economy dataset GTAP-EG which is based on the general Global Trade Analysis Project (GTAP) database and OECD International Energy Agency (IEA) statistics. The GTAP-EG dataset is developed in collaboration with the researchers at Purdue University, who created a GEMPACK version of the energy dataset. In contrast to their work, the GTAP-EG is implemented in the GAMS...

Abstract This study analyzes the effect of change in structure Japanese power supply, which disaggregates sector based on GTAP-E model framework. We analyze impact Japan’s macroeconomy, sector, and industry by comparing results four scenarios. In our simulations, are divided into two periods, shocks introduced to growth rate real GDP, labor force, population, zero-emission supply; nuclear power...

The agriculture directorate is using a modified version of the GTAP model to analyse the impact of agriculture and non-agriculture reform. This analysis is part of an overall project that analyses policy reform using a "top-down" approach that integrating a variety of modeling techniques. Global and regional analysis is carried out using general equilibrium (modified GTAP), while at the other e...

The making of projections often requires an economy-wide perspective, and the estimation of consumer demands at the international level. In this paper, an implicit, directly additive demand system (AIDADS) is estimated using crosscountry data on consumer expenditures from the International Comparison Program (ICP), and then from Global Trade Analysis Project (GTAP) data. The two data sets are f...

Global models of agricultural trade have a long and distinguished history. The introduction of the GTAP data base and modeling project represented a significant advance forward as it put modelers and trade policy analysts on common ground. After an initial generation of GTAP based modeling of agricultural trade policy using the standard modeling framework, individual researchers have begun intr...
