Description of the model

DG ECFIN's GDP growth projection is calculated from a dynamic factor model. It distils the relevant factors driving the euro-area business cycle from around 2000 time series for the euro-area countries. 
The model delivers technical projections for the present quarter and the two quarters ahead. It should be recalled that statistical models cannot include all the elements that affect short-term economic developments, e.g. institutional and structural changes in economies. Thus, the results are presented as ranges reflecting the unavoidable uncertainty surrounding such projections.

Factor models provide a means of summarising the information contained in large datasets by a small number of factors. 
The approach assumes macroeconomic time series have two components: 

  • a common component corresponding to the business cycle and 
  • an idiosyncratic component that is specific to each time series. 
  • The common component is relevant for forecasting purposes. Various estimation procedures have been developed to extract the common factors from the underlying time series data. The time series used in the current model were selected on the basis of economic judgement and are assumed to contain information about the current and/or future economic situation in the euro area.

    The model is described in detail in Economic Paper 219.
