The introduction of the single currency in the European economic space
constitutes without doubt the most visible step towards monetary and
economic integration in the EU. Those who boosted the birth of the
Common Market in 1957 dreamt that this would one day come about as a
logical consequence of the integration process. However, things have
gone much more slowly than possibly imagined, although if taken in an
adequate historic perspective, it is undeniable that the agreements that
have led to European Monetary Union signify a really formidable jump in
the process of political and economic integration in Europe. This is
something many doubted would ever happen, but which is already a
reality, although still in need of a period of consolidation. The most
general economic consequences of the EMU have already been analysed in
considerable depth. Proof of this is the literature already available.
In general, there is coincidence in affirming that the balance of the
results expected is clearly positive. Firstly, as a result of the
anticipated gains in efficiency, a consequence of reduction of
transaction costs associated to the previous existence of different
currencies and of the elimination of exchange rate uncertainties.
