Consider the implications that enlargement may have for the ideal of
the European social and cultural cohesion, by focusing on the way the
area of free movement of persons will be put to the test by the
inevitable increase in immigration.

Hello Anabel,
maybe u can find some help in "The Impact of EU-Enlargement on
Migration Flows into Styria, Carinthia and East Tyrol until 2011".
It's just a working paper, available at

Maybe it's only interesting for literature
Unfortunaly only in german available :0(

Abstract:
The present working paper analyses the migration potential arising
from the eastern enlargement of the European Union both in terms of
persons as well as workers. The region under investigation comprises
the Austrian states of Styria and Carinthia as well as Osttirol (a
region in Tyrol). Each of the two states are further subdivided into
three more regions. The study is based on a comprehensive
investigation commissioned by the EU (Boeri and Bruecker, 2000),
whereas the results of the authors in response to the amended time
frames surrounding the process of enlargement were adapted. Following
the network approach, the national total migration potential is split
up among Austria's regions according to the prevailing locational
pattern of residents from the MOEL under investigation for the two
periods until 2006 and 2011 respectively. Due to the initial accession
date in May 2004 the first time period is rather short and hence
migration is expected to remain low with about 7,700 persons or 2,700
workers potentially migrating to the southern parts of Austria until
2006. Both the accession of Romania and Bulgaria as well as the
extended time frame will lead to an marked increase in migration
between 2006 and 2011. More than 23,000 persons or almost 7,500
workers will potentially be migrating to Styria, Carinthia and
Osttirol in the second half of the current decade. Hence, in total
slightly more than 10,000 workers are estimated to be potentially
available for the labour market in the southern parts of Austria until
2011 due to the eastern enlargement of the European Union
