“…Studies on the economic alignment of countries have had different focus areas and levels: structural convergence at an industrial level (Höhenberger and Schmiedeberg, 2008), the role of agriculture in the process of structural convergence (Sassi, 2007;Fertő, 2016), the transition from an agriculture based economy to an industrial and then service one (Chong et al, 2017), regional convergence (Cuadrado-Roura et al, 1999;Guerrieri and Iammarino, 2003;Longhi and Musolesi, 2007;Crespo and Fontoura, 2009;Di Berardino et al, 2017) the relationship between income and structural convergence (Imbs and Wacziarg, 2003), convergence in the field productivity (Fagerberg, 2000;Gugler and Pfaffermayr, 2004) and the causal link convergence -monetary union integration (Brülhart, 1998). Other authors have analyzed economic catching-up process between groups of industrialized countries, newly industrialized and less industrialized (Abegaz, 2002) or of countries from Central and Eastern Europe (Landesmann, 2000) and, more recently, on the new EU member states Euro adoption (Miron et al 2009, Brixiova et al, 2009and Juncker et al, 2015, or a reassessment of the convergence achievements of countries which already are members of the Eurozone (Palan and Schmiedeberg, 2010).…”
