In some practical applications of transition models there is a natural limit on the duration of some state. An important example is the Youth Training Scheme (YTS), which is normally limited to two years. The authors modify the usual competing risks model for this case and derive a diagnostic...

We analyse transitions between pensionable jobs, non-pensionable jobs, and other labour market states, using the 1988/9 UK Retirement Survey. We focus on the positive association between length of job tenure and pensionable status, allowing for the possibility that pension scheme members are...

The diffusion of temporary work agency (TWA) jobs has led to a harsh policy debate and ambiguous empirical evidence. Results for the USA, based on quasi-experimental evidence, suggest that a TWA assignment decreases the probability of finding a stable job, while results for Europe, based on the...
