This is just one of the suggestions made in new research, funded by the UK's Economic and Social Research Council, into migration patterns in Europe.

It counters the common view that uncontrolled immigration would result in reduced average incomes, the displacement of local workers from jobs, and an increased burden on welfare services.
The research team, headed by Professor Roger Vickerman of the University of Kent, points out in its report that migration works most efficiently if migrants with particular skills can be matched with the needs of potential employers.
The report talks of the 'pressing need' for improved information on the labour markets of the EU, to be made available to potential migrants and employers.
It is critical of national immigration policies based simply on limiting numbers. Instead, the report backs 'an auction based system of migration permits, where permits are either auctioned amongst potential immigrants or their potential employers'.

Workers from the new member-states like Poland will seek to move to existing EU countries, while others from countries even further east, like Ukraine and Belarus, could seek to take their places.
The new research effectively explodes some popular myths and prejudices about migration. Among the findings:
