A new working paper from Niall Conroy and Eddie Casey of the Fiscal Council Secretariat.
The Council’s mandate includes endorsing, as it considers appropriate, the official macroeconomic forecasts of the Department of Finance on which the annual Budget and Stability Programme Update are based. As part of the endorsement process and for the purposes of its ongoing monitoring and analysis of the Irish economy, the Council’s Secretariat produces its own Benchmark macroeconomic projections. This paper describes the short-run forecasting models used by the Secretariat for producing these projections. The general forecasting approach can be described as follows. Equations are used to forecast each component of the expenditure side of the Quarterly National Accounts. Multiple models are estimated for most components, with the simple model average used as an initial input into the formulation of the Benchmark projections. The out-of-sample forecasting performance of these models is assessed at each endorsement round. In addition to these model-based projections, other elements are considered. Discussions with the Council and other forecasting agencies help to guide any judgement that may be applied before arriving at the final Benchmark projections.
