WorldScan

WorldScan is a flexible model that CPB developed to explore and analyse long-term issues in the world economy. The model has repeatedly been used as a tool to construct long-term scenarios and is often deployed for policy analysis.
In scenario development, WorldScan acts as an organising device to explore and discuss the potential impacts of current trends such as ageing, the rise of emerging countries, the depletion of fossil energy resources or rising emissions of greenhouse gasses. Simulating these developments may reveal important impacts on the world economy and identify related policy problems. Long-run scenarios have frequently been used as baselines for exploring the impacts of alternative policy options with WorldScan, for example in the fields of global warming, economic integration and trade liberalisation.
Specific policy assessments often require adjustments of the model. Hence, WorldScan has frequently been adapted to make the model better geared to specific problems. A detailed publication brings the model changes together, explains the model's current structure and illustrates the model's usage with some applications.
