EurActiv is an extremely useful source of information and analysis (much better eg that EU Observer or Eupolitix, for example). Today they have an interesting survey of the recent debate about the efficacy of the euro. They also have a link to a recent report which seems interesting.
“The rejection of the Constitution by two of the EU’s founding members – France and the Netherlands – has raised concerns about the long-term future of European Monetary Union. But other comments have also led to some extra market volatility for the single currency. Arguably, French and Dutch voters did, in 48 hours, what the European Central Bank has been trying to do for six months – namely reduce the value of the euro.”
