The presented work was written during my time as an external PhD student at the Department of Public finance at the Otto-Friedrich University of Bamberg under the guidance of Prof. Dr. Dr. h.c. H.-Dieter Wenzel. I would like to express my gratitude to the many people who provided support during my dissertation. Without their continued efforts and support, I would have not been able to bring my work to a successful completion. I would like express my gratitude to my first mentor, Prof. Dr. Dr. h.c. H.-Dieter Wenzel for his extraordinary support during my research. His most useful comments and suggestions helped me bring my work to a successful completion. In more than ten years, he has contributed significantly to rebuilding and uniting academic community in the South Eastern Europe and I was very lucky and honoured to have been given the opportunity to do a PhD under his supervision. I would also like to thank my second mentor, Prof. Dr Sead Kreso for his excellent guidance, caring and patience for my everlasting questions. His numerous beneficial comments and talks helped me to comprehend the complexity of the society as a whole which surpasses this thesis.weiterlesen
