Approach

WorldScan is a flexible model based on GTAP developed to explore and analyze long-term issues in the world economy. The model is used as a tool to construct long-term scenarios and perform policy analysis. In scenario development, WorldScan acts as an organizing device to explore and discuss the potential impacts of current trends such as aging, the rise of emerging countries, the depletion of fossil energy resources or rising emissions of greenhouse gasses. The model also functions as a flexible modeling framework for addressing policy issues in international economics.
