SAFFIER; a multi-purpose model of the Dutch economy for short-term and medium-term analyses

Since late 2004, CPB Netherlands Bureau for Economic Policy Analysis has been using the macro-econometric model SAFFIER for its short-term and medium-term analyses. This model resulted from the integration of the quarterly model SAFE and the yearly model JADE. SAFFIER is a multi-purpose model. The quarterly version of the model, used for short-term analyses, only differs from its yearly version, used for medium-term analyses, in the specification of the lag structures. All other (non-technical) specifications are identical in both versions of the model. Simultaneously with the integration of SAFE and JADE, some innovations with respect to the modelling of the wage rate, private consumption, exports, the public sector and the house-price development have been incorporated. In the wage equation, the elasticity of the replacement rate is no longer constant, but is depending on the actual labour-market situation. This publication sketches the outlines of the SAFFIER model, focusing on the main innovations. In order to explain the working of the model, the results from a number of standard shocks are presented.
