This paper analyses the economic effects of different magnitudes of tariff cuts, different tariff cutting formulas, the implications of tariff capping as well as different numbers and width of tariff bands in the market access pillar of the Doha Round agricultural negotiations. The simulations are conducted with an extended version of the GTAP model and an extended version of the GTAP data base...

Computable General Equilibrium (CGE) models have been widely used for quantitative analysis of global economic issues. However, CGE models are frequently criticized for resting on weak empirical foundations. This paper builds on recent work in macro-econometric estimation, developing an approach to parameter estimation for a widely employed global CGE model, the Global Trade Analysis Project (G...

This paper documents a new version of the GTAPinGAMS package which includes two global economic datasets, GTAPinGAMS and GTAP-EG, corresponding illustrative models, and several ancillary programs for dataset management. The GTAPinGAMS is a dataset based on a general GTAPv4 dataset. The GTAP-EG is the energy-economy dataset adjusted for OECD International Energy Agency (IEA) statistics. The illu...

Biofuels impact on global land use has been a controversial yet important topic. Up until recently, there has not been enough biofuels to have caused major land use change, so the evidence from actual global land use data has been scant. However, in the past decade, there have been 72 million hectares added to global crop cover. In this research we take advantage of this new data to calibrate t...

Since China’s application in 1987 to resume its status in the Generalized Agreement on Trade and Tariffs (GATT)/World Trade Organization (WTO) there has been a great deal of debate over the timing of China’s accession. Although most of the issues relating to the timing of China’s trade liberalization have been resolved, the abolition of restrictions on Chinese textiles and clothing may still be...

the purpose of this study is to evaluate the impact of import of technology on iranian economy. we have used multi-sectoral and multi–regional computable general equilibrium gtap model. transfer of technology from one region to another is another factor effecting productivity. trade is one of the channels that speeds the transfer of technology. the effect of a ten percent productivity shock, in...

This paper provides a quantitative study of the economic effects of a stylised simulation of trade liberalisation for Ireland using the GTAP model. The experiment incorporates the liberalisation of agricultural, manufacturing and services trade as well as measures to improve trade facilitation. The simulation is implemented against a baseline projection of the Irish and world economy over the n...
