“…There are many fiscal as well as monetary indicators, where convergence is desirable for further common development of the European Union as well as for enhancing its position in comparison with other developed countries. Most often the indicators of gross domestic product per head or real income per head are applied to the real convergence analysis (for example Martín et al, 2001, Žďárek and Šindel, 2007, Halmai and Vásáry, 2010, Dobrinsky and Havlik, 2014or ECB, 2015. Another group of authors is engaged in the nominal convergence analysis and monitor comparative price levels, interest rates or inflation rates development (de Grauwe and Schnabl, 2005, Hein and Truger, 2002, Žďárek and Šindel, 2007, Barbosa and Alves, 2011 or Groll and van Roye, 2011).…”
