Economic globalisation, transnationalism and established diaspora communities have increased the circulation of people. New migrations have emerged, many of them short-term, taking advantage of opportunities to exploit niche labour markets. Shortages of skill and manpower at the top and bottom ends of the labour market have increased openness to foreigners.
