Immigrant economic assimilation: Evidence from UK longitudinal data between 1978 and 2006

Using the underexplored, sizeable and long Lifetime Labour Market Database (LLMDB) we estimate the immigrant-native earnings gap at entry and over time for the UK between 1978 and 2006. That is, we attempt to separately estimate cohort and assimilation effects. We also estimate the associated immigrant earnings growth rate and immigrant-native earnings convergence rate. Our estimates suggest that immigrants from more recent cohorts fare better than earlier ones at entry. Furthermore, the earnings of immigrants from more recent cohorts catch up faster with natives' earnings. While the convergence took over 30 years for those entering in the post-war, it only took half as long for those entering in the early 2000s. This earnings growth is fastest in the first 10 years, and it considerably slows down after 30 years.
