International migration, seen as a powerful force of truly global character that is shaping today's socio-economic reality, is a highly controversial and politicised issue. This paper explores its ramifications in the context of a growing backlash against immigration across the rich world. Specifically, it argues that the free flow of people – like the free movement of goods and capital – is beneficial to developed and developing economies alike and, in doing so, shows how migration produces win–win outcomes. Thus the study, while admitting that inflows of foreign-born workers pose challenges and entail trade-offs, makes a case for the liberalisation of immigration policies. The paper deepens our understanding of the issues at hand and constitutes a voice in favour of liberal-policy choices.
