This paper uses the global trade analysis project (GTAP) to evaluate impact of grain export restrictions on world food security during COVID-19 epidemic. The study found that distort market prices, which in turn consumption and production, harm interests consumers farmers some countries, threaten security. In this regard, maintaining convenience is wise choice all countries. It necessary tighte...

Abstract Using the Global Trade Analysis Project (GTAP) computable general equilibrium model, we analyze economic impacts of grain export disruptions caused by Russia–Ukraine War during first year hostilities. The simulation results indicate that these not only affect Ukraine and Russia but also generate significant across other world regions. is projected to experience largest impact on its ow...

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 ...

We discuss how to avoid aggregation bias in large-scale global Computable General Equilibrium (CGE) models by reducing the need of pre-model aggregation, based on the combination of algorithmic improvements and a filtering approach which removes small transactions. Using large-scale sensitivity analysis, we show the impact of pre-aggregation and filtering on model size, model solution time and ...

The economic impact of extending the Common Agricultural Policy (CAP) to the Central and Eastern European countries has become a major issue in the European enlargement debate. This paper addresses this issue by providing an assessment of the economy-wide effects of European enlargement using a global general equilibrium model where special attention is given to modelling the instruments of the...

Carbon leakage can be a problem when seeking to reduce carbon emissions through forest policy. International market leakage is mainly caused by supply and demand imbalances in the timber market. This paper selects China, which is implementing forestry policy changes, as the research object. We begin by offering a brief analysis of China’s forestry policy changes, such as the logging quota and S...
