Leprechaun economics was a term coined by economist Paul Krugman to describe 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. At that point, the distortion of Irish economic data by tax-driven accounting flows reached a climax. In 2020, Krugman said the term was a feature of all tax havens.
