Potential Output and Output Gaps

 

Happy new year to all. In case some of you missed it, the Department of Finance published two working papers (by Gavin Murphy, Martina Nacheva and Luke Daly) just prior to Christmas looking at the ever topical issue of Ireland’s output gap. Both papers can be accessed at this link. The first paper takes a detailed look and review of the main methods used to estimate the cyclical position of an economy. The authors highlight the diversity of modelling approaches used across institutions both within Ireland and abroad. The second paper outlines in detail the methodology used by the Department to produce estimates of the output gap for Ireland. To date, the Department has used the European Commission’s harmonised approach (i.e. common to all EU Member States), which has at times resulted in counterintuitive estimates of Ireland’s cyclical position. This research seeks to develop more plausible estimates taking better account of the nature of Ireland’s small open economy. Such work will enable the Department to better evaluate the appropriate fiscal stance and the sustainability of public finances over the medium term.  For those with an interest in macroeconomic modelling and forecasting as well as fiscal policy related issues, the papers offer an invaluable source of information into what can be a complex area.
