1 Introduction
1.1 Background
Although the issue of migration has received substantial attention in public
debate in most countries of the West, only moderately satisfactory atten
tion has been given in the economic literature. In the case of Germany in
the 1960's, an active Gastarbeiter recruitment policy of importing temporary
foreign workers from such low-wage countries as Turkey, Italy, Spain, Greece
and Yugoslavia was adopted in an effort to quell overheated domestic labor
demand. After the first Oil Crisis in 1973, and in the face of recession and
rising unemployment, the federal government, concerned with the additional
wage and employment impacts of migration, ended this policy. However, those
"temporary" foreigners already in Germany, chose overwhelmingly to stay,
even with the offer of financial assistance to return to their home countries.
The question of migration has become acute again, with the fall of Social
ism in Eastern Europe in early 1990, and the 1992 movement toward general
European Union (EU) integration.
In the past, definitive answers to many very basic labor market policy ori
ented questions have not surfaced. Are there substantial negative side-effects
of migration, faced by native workers, as sometimes publicly claimed? Do
some groups of natives fair better than others in the face of immigration ?
Do highly skilled and unskilled natives experience different effects ? In or
der to make policy decisions, how does one best quantify this phenomena
called "migration", and what underlying assumptions need to be made in
the analysis ?
Virtually no attention in the German migration literature has been given
to the following questions: Do certain foreigner national groups affect natives
differently ? How important is the level of education of these incoming for
eigners in determining wage impacts on natives? Do native workers in some
industries profit from migration, while others suffer ? How is the industrial
wage structure affected by migration, if at all ? In carefully examining native
