“…As for specialisation, earlier studies employed export data to assess country specialisation patterns (see, among others, e.g., Aquino, 1978;Sapir, 1996), while other studies analysed country specialisation using production data, such as employment, value-added, or output (see Combes and Overman, 2004 for a comprehensive survey). While Amiti (1999) reports a general increase in relative specialisation in EU countries from 1968to 1990, Midelfart-Knarvik et al (2004 tend to suggest that the process of relative specialisation is more complex at least from the early-1980s until the end of the 1990s. Recent studies, focussed on EU-27 countries, suggest increasing specialisation of the new member states (see e.g., Bagoulla andPéridy, 2011 andVechiu andMakhlouf, 2014).…”
