On both of these aspects the euro has had a mixed or unfavourable impact: the changeover of notes and coins does indeed seem to have caused an upsurge in prices – let us hope that it is only a temporary one – and as for growth, we are still waiting for the 'doping effect' which monetary union, according to its champions, was supposed to unleash.
Sur ces deux points, l'euro a eu un impact mitigé, ou défavorable : l'échange des pièces et des billets semble bien avoir été à l'origine d'une poussée des prix, espérons-le, passagère ; quant à la croissance, on attend encore l'effet de "dopage" que, selon ses zélateurs, l'unification monétaire était censée provoquer.
