A disaggregate analysis of the evolution of job tenure in Britain, 1975-1993

We use data on 200,000 individuals to investigate changes in job tenure. We look at the age-tenure profile for different birth cohorts of workers and find little change for men and an improvement for women. We estimate probab ility models for two cuts of the tenure distribution. We find that, control ling for a set of age, demographic, educational industrial and occupational characteristics, the proportion of workers in short jobs and longer jobs h as the same path as in the aggregate (unconditional) analysis. Allowing for the effect of all these characteristics to vary with rime uncovers no evid ence of secular change.
