A Birth Cohort Analysis of First Employment Spells *

Abstract The duration of the first employment spell of workers across five different birth cohorts is investigated using pooled data from the 15th and 20th cycles of the Canadian General Social Survey. These retrospective surveys contain information that spans well over the last half of the 20th century. The data are benchmarked against the Labour Force Survey to emphasize the distinct nature of employment spells vis-a-vis job tenures as commonly used in the literature. Overall, this paper contributes to the debate of employment stability by analyzing the differences between job and employment durations and showing that successive cohorts of workers have had increasingly shorter first employment durations. The analysis finds cohort effects which play a significant role in explaining declining employment tenure. The cohort effects can be seen as a proxy for a number of socio-economic factors that affect the hazard of separation from employment. Separate analysis is completed for men and women by birth cohort. This pattern of declining tenure has occurred for both men and women, but the decline has been far more prominent for men. For men, macroeconomic factors affect the hazard more strongly in more recent cohorts, which is consistent with recessionary periods generating decreasing employment stability across cohorts. For women, cohort effects are consistent with the increasing generosity of maternity leave provisions through Unemployment Insurance

Duration Dependence in Employment: Evidence from the Last Half of the 20th Century

This paper extends the investigation of Ignaczak [5] of the first employment spell of workers across five different birth cohorts using pooled data from the 15th and 20th cycles of the Canadian General Social Survey (GSS) to subsequent spells of employment with the purpose of testing for employment duration dependence. As the information on the GSS surveys spans well over the last half of the 20th century we are able to test not only the potential duration dependence but its stability over time. This paper contributes to the debate of employment stability by analyzing the differences between job and employment durations and showing that successive cohorts of workers have had increasingly shorter first employment durations.

A Nonparametric Analysis Of Canadian Employment Patterns

Popular perception holds that employment stability has decreased in recent decades. However, no conclusive evidence exists on secular declines in the length of jobs held. Furthermore, most studies conclude that the proportion of long term jobs has remained remarkably stable over the last few decades. To shed light on this discrepancy we use distribution analysis to systematically track changes in Canadian employment durations over an extended period. This is done in order to reconcile popular perception with recent studies and nest the existing literature in a broader historical context. Using finite mixture decomposition on successive cohorts of workers starting from the 1950s we identify worker types within cohort-based distributions. Then, using tests of stochastic dominance, we show that the distribution of employment has indeed changed. The finite mixture decomposition reveals that earlier cohorts were more likely to have longer tenure than later cohorts and that there are shifts in pro-portions between longer and shorter work episodes. Our results also indicate that after the 1960s employment durations declined sharply for men, while for women the results were mixed

To shed light on this discrepancy we use distribution analysis to systematically track changes in Canadian employment durations over an extended period. This is done in order to reconcile popular perception with recent studies and nest the existing literature in a broader historical context. Using nite mixture decomposition on successive cohorts of workers starting from the 1950s we identify worker types within cohort-based distri-butions. Then, using tests of stochastic dominance, we show that the distribution of employment has indeed changed. The nite mixture decomposition reveals that earlier cohorts were more likely to have longer tenure than later cohorts and that there are shifts in pro-portions between longer and shorter work episodes.

Do the determinants of employment duration vary across employment spells?
