This paper seeks to review a selection of ten salient critical claims about Economic and Monetary Union (EMU) that were heard in the 1990s in either the Political Science literature or the Economics literature or both. In this paper, the author focuses on five salient Political Science claims and five Economics claims prominent at the time that pointed to problems with EMU that could undermine its viability. As we will see, based on an assessment of the first ten years of EMU, almost none of these claims -to date -turned out to be a problem.
