The study is based on the critical observations that the competitive market forces alone are not able to assure the convergence with the developed countries. 

The study defines the three types of convergence – institutional, nominal and real ones –, the connection among them and their main measurement indicators. 

This study offers from the beginning a survey about the institutional construction in the pre- and post-adhesion stages to European Economic and Monetary Union, about the exchange rate mechanism applied by the different countries and about convergence criteria.
