Climate change is a long-term issue due to the long lifespan of greenhouse gases and the delayed response of the climate system. This paper investigates the long-term economic consequences of both climate change impacts and mitigation efforts by applying the multiregional, multi-sectoral integrated assessment model WIAGEM based on GTAP-E –L coupled with the reduced-form multi-gas climate model ...

Abstract Climate change and global warming have significantly threatened food security the supply chain. As trade volume of bulk commodity grains has been growing steadily, ensuring quality while minimizing losses during long-distance shipping between warm cold seawater become a critical issue. An evidence-based approach to provide quantified implications is needed illustrate roadmap toward net...

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...

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...
