“…However, it is important to highlight, that contrary to most traditional migration countries, foreign population in Greece is rather homogeneous, as the majority of migrants stem from a single country, the neighbor Albania (almost 50%). What is more, Greece mainly attracts unskilled migrants, who experience further “downgrading” in the Greek labor market (i.e., they tend to work into occupations which require less formal qualifications than theirs) due to differences in the quality of schooling between Greece and the sending countries (see e.g., Chletsos & Roupakias, forthcoming). As discussed in Peri (), these features, common in Southern European countries, stem from the fact that the skill premium is significantly lower that it is in the Anglo‐Saxon economies, and tend to reduce the expected gains stemming from possible complementarities and positive spillovers spurred by the presence of heterogeneous (in terms of birthplace and educational attainment) foreign populations.…”
