The project´s aim is to establish and maintain a user-friendly modelling toolbox for the analysis of macroeconomic effects from labour market policy. Thus, besides our concern with consistent macroeconomic simulation of policy impacts based on a microeconomic foundation, flexibility and user-friendliness acted as additional objectives in the development process. Flexibility is afforded in order to allow for the application to a broad range of ever changing research questions. User-friendliness in this context posits the requirement of a widely self-explanatory interface structure and the immediate grasp of key results in the comparison of alternative policy scenarios.
