For many experts the true motivation behind the introduction of a single
currency in Europe is political rather than economic. This view is based on
the fact that the euro area does not constitute an optimal currency area and,
therefore, the costs of monetary integration are likely to outweigh the
benefits. In particular, the loss of control over monetary policy and
exchange rates make overcoming asymmetric demand-side shocks very painful.
Moreover, the monetary union lacks a common fiscal authority that could help
in smoothing out business cycles. The present crisis exposed these
vulnerabilities and, unfortunately, so far economic policies adopted in the
region have failed to rectify these shortcomings.
