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 are preferences, the smaller the elasticity of substitution in the aggregate utility function, and the greater the v...

The African Continental Free Trade Area (AfCFTA) entered into force in May 2019 after surpassing the required 22 ratifications. This article combines decision support model (DSM) and Global Analysis Project (GTAP) computable general equilibrium (CGE) to make quantitative assessments of expected welfare trade effects AfCFTA on Nigerian South sectors possessing sustained export potential within m...

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...

Mitigation of CO2 emissions is a global public good that imposes different regional economic costs. We assess the distributional effects cooperative versus non-cooperative markets to fulfil Nationally Determined Contributions (NDCs), considering permit allocation rules in markets. employ computable general equilibrium model based on GTAP-9 database and add-on GTAP-Power database. Our results sh...

This paper describes the construction of GTAP Data Base, version 11. The database reconciles different data sources at a global scale for analytical use and provides time series on value flows, volumes, various tax instruments. 11 has 5 reference years (2004, 2007, 2011, 2014, 2017), distinguishes 65 sectors in each 141 countries 19 aggregate regions - with individual accounting 99.1% world GDP...

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...
