The debate on the free movement of labour within the EU has gained new momentum in the wake of the economic crisis. Building on the earlier Ashgate publication EU Labour Migration Since Enlargement, the editors have assembled a team of experts from across Europe to shed light on the critical issues raised by internal labour mobility within the EU in the context of economic crisis and labour market pressures. The book's chapters tease out the links between economic developments, regulatory frameworks and migration patterns in different European countries. A central focus is on issues of skills and skills mismatch and how they relate to migration forms, duration and individual decisions to stay or return. Based on detailed analysis of European and national-level sources, the results presented clearly contradict assumptions about a "knowledge driven migration". Rather, over-qualification and the corresponding underutilisation of migrant workers' skills emerge as a pervasive phenomenon. At the same time the characteristics of migrants - not just skills, but socio-demographic characteristics and attitudes - and also their labour market integration are shown to be very diverse and to vary substantially between different sending and receiving countries. This calls for a differentiated analysis and raises complex issues for policymakers. Examples where policy has contributed to positive outcomes for both migrants and domestic workforces are identified. Unique in analysing labour migration flows within the European Union in a comparative manner putting skills into the centre and taking account of the effects of the economic crisis, while addressing policy concerns this is a valuable resource for academics, policymakers and practitioners alike.
