Competition Policy reform measures passed after 2003 had the intended desire to increase integration within states. Given the current challenges being faced, I think that it will be nearly impossible to tell what result these initiatives had until later on down the line. Consider that in 2003, competition policy reform in light of expansion becomes one of the primary challenges that the European Union were to face:
From a very broad point of view, these reforms aim at improving the effectiveness of our competition policy and at enhancing its real impact in opening and maintaining competitive markets... as the EU grows in May 2004 to 25 member states—the largest enlargement in our history—we will have to guarantee that business and authorities are able to operate under the same competition policy constraints in the whole EU, despite the marked divergences between economic development and competition background that will exist within our borders.
Competition policy reform as back as 2003 was seen as being able to deal with the reality of bringing more states into the European Union. I think that it became evident that the competition policy reform ideas that were being advocated in the earlier part of the 2000s were conceived with the idea of being able to effectively address the idea of growth and bringing in more nations into the Union. With the upcoming vote on austerity and "Grexit" this month, such an idea will prove to be even more relevant as it was initially introduced in the early 2000s.
Thank you very much for your answer.
