Lately the problem of convergence in the European Union has been moved from the level of countries or groups of countries to the regional level. In matter of real convergence, empirical evidence is demonstrating a trend of convergence, as it is between former communist countries accepted in EU during the last decade (EU11 group) and old EU members (EU15). Thus, as a rule, higher growth rates were

However, a main goal of the EU strategies is to ensure an irreversible convergence among regions on the long-run. Despite of fact that many policies in the EU focussed on reducing discrepancies among regions, a divergence process often persisted for the majority of countries in the EU, as our study demonstrates by using data available at NUTS2 level for the period 2000-2013. Additionally, the real dynamics for each country or region is compared with an optimal trajectory estimated by applying nonlinear simulation models.
