Course description

This course is designed for advancing the knowledge and experience in CGE modelling and prepare students for using and adapting state-of-the-art multi-regional CGE models for own research. It focuses on the widely used multi-regional CGE model GTAP and variants thereof, as implemented in CGEBox. Students are not expected to work in software codes, but use Graphical User Interfaces.

The following topics will be covered

The course is a combination of presentations by instructors and students, PC demonstrations, group work and assignments. During the course, participants will work in subgroups in parallel and prepare each day a presentation on a selected topic. Instructors will provide feedback and will be available during the group work phases to help with technical problems and/or to answer related questions.
