Working Paper: Investigation into North/South Trade Statistics

This report investigates the differences between North/South trade figures up to 2006 published by CSO, HMRC and DETI. It is a follow-up to the 2003 report which considered broadly similar issues. Since the 2003 report, however, there have been significant changes in the methodology applied to the HMRC data and increasing discrepancies between the different data sources have become evident.
