The aim of the project was to further develop an existing econometric modeling tool to carry out scenario analyses. For this purpose, the macro-econometric model PANTA RHEI has been updated and adjusted for the Federal Environmental Agency (UBA). The client is now possible to perform simulations and evaluate economic developments and policies independently. The user-friendly interface “IMAGINE” enables the user to get an overview of modeling aspects and displays model variables in graphs and/or tables as selected. Furthermore, standardized routines convert the data into excel spreadsheets.
