Abstract: The article assesses the usefulness of indicators taken from surveys carried out by the National Bank of Belgium for predicting Belgian GDP and other important quarterly macroeconomic aggregates. To this end, the authors use the recently created BREL now-casting platform that consists of targeted bridge models for different data availability scenarios. BREL is based upon an elastic-net regression approach that takes into account the ragged-edge nature of the data set. The results of their empirical analysis suggest that survey data clearly help to predict Belgian (but also European) macroeconomic developments, in particular for earlier estimates, when the relevant hard data, notably firms’ turnover and industrial production, are not yet available. They also show that forecast accuracy is higher when using disaggregated survey results, rather than just the headline consumer confidence and business sentiment indicators. In this connection, demand expectations in the manufacturing industry and the unemployment expectations in the consumer survey consistently feature among the best predictors for real GDP growth.
