THE PERFORMANCE OF IMMIGRANTS IN THE NORWEGIAN LABOR-MARKET

This paper tests the assimilation hypothesis with Norwegian data. Usin g both cross-section and cohort analyses, the results show that the 19 70-1979 immigrant cohort experienced an earnings growth of about 11% b etween 1980 and 1990, when their earnings profile was compared to that of natives. This is lower than the 19% assimilation rate predicted by the cross-section method. On the contrary, the results reveal a rapid earnings divergence across cohorts, and between the 1950-1969 cohort and natives. It is also shown that the ''quality'' of successive immig rant waves has declined over time, thus biasing the cross-section esti mates of assimilation.
