Leprechaun economics was the 26.3 per cent rise in Irish 2015 GDP, later revised to 34.4 per cent, in a 12 July 2016 publication by the Irish Central Statistics Office (CSO), restating 2015 Irish national accounts. The term was coined by Nobel Prize–winning economist Paul Krugman to mark the fact that the long-term distortion of Irish economic data by tax-driven accounting flows had reached a climax; by 2020, Krugman said the term was a feature of all tax havens.
