GREM is a macroeconometric model based on annual data, constructed by GRETA in order to provide alternative scenario forecasts of economic variables that are prominent in the regional programming process and in the evaluation of Community structural assistance. The time forecasting horizon is 2013 in agreement with the actual European programming horizon, but it can be modified on the user’s request.

The aim of GREM is to satisfy the information needs that arise in regional programming process and in the impacts evaluation process at European, national and local level. The model is quarterly updated and can therefore provide a continuous view of the expectation changes due to short term policy variations.

The major feature of the service is the definition of two alternative scenarios of markets evolution. It also provides the possibility for users to propose alternative scenarios based on their own assessment of the conjuncture behaviour.
