Globalisation has increased the global supply of low-skilled labour, affecting wages and employment prospects of workers with low qualifications. At the same time, more intense international competition for high-skilled workers has pushed up top incomes. Advances in information and communication technology (ICT) are also favouring high-skilled workers, whose task cannot be easily automated, and thereby increasing inequality (Kierzenkowski and Koske 2012). Some studies suggested technological change is a more powerful driver of inequality than globalisation (IMF, 2007, OECD, 2007a).
