The topic of my Bachelor Thesis is „The impact of Euro introduction on the European Economic and Monetary Union’s trade – expectations and reality“. My intention was to compare the expected and the real consequences. In the first part of the Bachelor Thesis, I focused on presenting a process of establishing and basic characteristics of the Monetary and Economic Union itself. The second part of the thesis summarizes a common currency features. The third part analysis what was generally expected from Euro implementation. In the very last part is being summarized what kind of trade changes really occured after some countries accepted Euro as their official currency.
