Fully reconciled GDP forecasts from Income and Expenditure sides

Abstract

We propose a complete reconciliation procedure, resulting in a ‘one number forecast’ of the GDP figure, coherent with both Income and Expenditure sides’ forecasted series, and evaluate its performance on the Australian quarterly GDP series, as compared to the original proposal by Athanasopoulos et al. (2019)¹.
