Thus, for example, in his paper From Accession to Cohesion: Ireland, Greece, Portugal and Spain and Lessons for the Next Accession (2003), he critically examined the first achievements of the European Union cohesion countries – an analysis which proved to be particularly relevant during the economic crisis which broke out in 2007.
So nahm er u. a. in dem Aufsatz „From Accession to Cohesion: Ireland, Greece, Portugal and Spain and Lessons for the Next Accession“ (2003) kritisch die ersten Erfolge der EU-Kohäsionsländer unter die Lupe, eine Analyse deren Richtigkeit sich spätestens in der Wirtschaftskrise ab 2007 bewahrheitet hat.
