Optimum currency area - reality in eurozone

My bachelor paper deals with a question, if the European monetary union follows the Optimum Currency Theory's criteria and forms an optimum area. I tried to assess, whether benefits of forming this integration in Europe outweigh costs or not. First part of this paper describes evaluation of this theory. Not only did I mention most widely known criteria such as Mundell's, Mckinnon's, Kenen's, but I also mentioned some others, which were defined during last few decades. In the second part, I analysed data and tried to find out to what degree the criteria are fulfilled. On the basis of this analysis I can say, that the European optimum union does not form an optimum currency area
