Whilst this Article has been accepted for publication by the ESRI, the views expressed are not necessarily the views of the ESRI) Special Article in the Quarterly Economic Commentary, Autumn 2008 Annual GDP growthAn analysis of revisions to Ireland's Quarterly National Accounts shows that relative to the growth rates experienced in the last decade, revisions to quarterly year-on-year growth rates have been in line with international norms. The analysis also shows that there is no systematic bias (positive or negative) in the revisions to these annual growth rates. These are the principal findings in a paper by Patrick Quill, Statistician, CSO, in the Autumn 2008 edition of the Quarterly Economic Commentary, published by ESRI. The article uses revisions analysis methods developed by the OECD. The largest revisions to annual GDP growth rates occur between three months and one year after the first estimate. In this period revisions range from - 2.7 to 2.9 percentage points. The mean revision for this period is 0.34. This result is not statistically different from zero. The mean of the total revisions (between the first and latest estimates) is 0.45. Again this result is not statistically significant. The difference between the first published and latest estimates of GDP growth ranges from - 3.5 to 3.8 percentage points. Main causes of revisionsThe article finds that revisions to imports and exports of goods and services are the main drivers of revisions to GDP growth rates. This reflects the fact that Ireland is a small open economy with combined imports and exports equal to roughly 170% of GDP, a big proportion of which is generated by large multinational enterprises and financial services companies. These enterprises frequently change their trading arrangements and company structures with consequential effects on the reported data, often involving re-statements of their returns for earlier quarters. GNP growth ratesThe article finds that revisions to GNP growth are much more volatile than revisions to GDP growth. Although again no statistical bias was found to the revisions, the range was greater thanfor GDP. The difference between these two measures is foreign net factor income, consisting mainly of profit flows of large multinational enterprises. The article highlights that early estimates of these profit flows are subject to considerable revision. Seasonally adjusted quarter-on-quarter GDP growth rateRelative to the size of GDP growth, revisions to the quarter-on-quarter seasonally adjusted series are larger than revisions to the year on year series. The mean of the total revisions (between the first and latest estimates) of the seasonally adjusted quarter-on-quarter growth rate is 0.35. This result is statistically significant. This suggests that CSO has tended to underestimate the first estimate quarter-on-quarter growth rates in the seasonally adjusted series. BackgroundThe author stresses that the results are based on a relatively short series. The Quarterly National Accounts has been published by CSO since 1999. The seasonally adjusted series has been published since 2003. By comparison the UK has published quarterly accounts since 1955 and the United States has published quarterly accounts since 1947.
