Estimates on the basis of German register data for the period 1975-97 do not confirm the hypothesis that penetration of migrants into skill cells has a significant negative effect on the earnings and employment opportunities of native men. The results indicate that a 10 percent rise of the share of mmigrants in the workforce would in general reduce wages by less than one percent and not increase unemployment. Though the adverse effects appear stronger for less-qualified and older workers, the evidence altogether sharply contrasts that from a parallel study for the United States indicating a consistent and substantial negative impact of an immigrant labor supply shock on native competitors.
