Since 2008, it‟s argued that the financial crisis in the Euro zone has demonstrated
that the region was not mature enough to adopt the euro as a currency. A retrospect
on the Maastricht convergence criteria and on the Optimum Currency Criteria put
forth, clearly points out the deviations in the fulfillment of these criteria in the
conception and functionality of the so-called euro area. The goal of this research is to
measure the effects of the 2008 financial crisis in the Eurozone by considering
exchange rate volatility (risk) on trade flows between the United States and the
Eurozone. The null hypothesis being that exchange rate volatility affects trade flows
and consequently renders monetary policies ineffective was tested against the
alternative hypothesis.
This research is prepared in two main parts; in the first part, a review of relevant
literature of optimum currency areas is considered, followed by a careful track-down
of the euro area monetary systems. The first part concludes in finding out if truly the
euro area is an example of a currency area. The second part is the technical frame of
the research; an econometric model is applied on trade flows and exchange rate
variations, in order to test the Eurozone as an optimal currency area the study
employed a conditional autoregressive distributed lag model as its empirical
methodology, which verifies co-integration between variables and further
differentiate the short and long run impacts. The selection of the appropriate model
or the lag length is based on Schwarz Information Criterion and Akaike Information
Criterion. The data is a quarterly time series data from 1999 to 2014, which provides
enough observations for the time-series econometric model. The last part pays
special attention to the Greek economy vis-à-vis the on-going financial turmoil. An
analysis on the future of the European monetary system is equally evoked while
incorporating the newest reactions/debates as regards the on-going crisis in the Euro
zone.
After the technical analysis of trade flows, exports were found to be more sensitive
than imports to exchange rate volatility. The short run causality effects were
generally minimal and the speed of recovery back to the macroeconomic equilibrium was higher in exports. In definitive, the euro area is not a perfect example of a
currency club as pointed out by the transfer of asymmetric shocks to members.
