Interested in quantifying the association of group-specific life courses with group-based inequalities?🕵️‍♀️

Check out my talk on life-course-sensitive decompositions of group-inequalities! Both approaches reveal mechanisms that are concealed in standard decompositions

Towards more life-course-sensitive decompositions of group-inequalities
2024-04-24 | Input Talk | Carla Rowold Abstract Life courses become increasingly complex and determine inequalities in outcomes between groups. However, research often decomposes group gaps in life-course-sensitive outcomes based on a selective set of life course summary measures, such as the years spent in (full-time) employment. One example of group-specific outcomes is the Gender Pension Gap. In my dissertation I developed and applied two innovative combinations of methods: i) sequence analysis with the Kitagawa-Oaxaca-Blinder decomposition, as well as ii) the Life Course Feature Selection with the Ñopo decomposition. This talk guides through the practical application of both and presents the methodological and substantial contributions of both approaches that can be easily applied to other life-course-sensitive group inequalities. Presenter(s) Carla Rowold is a PhD candidate in Sociology at the University of Oxford and a postdoctoral researcher at the Max-Planck-Institute for Demographic Research. In her dissertation, she explores life-course- and gender-sensitive approaches to assess the link between gender inequalities over the life course and the Gender Pension Gap. Her research interests cover life course sociology and inequalities, particularly among genders, social demography, and work-family and retirement policies.

The procedure provides robust estimates for an association of interest.
It also identifies central and borderline trajectories within each cluster.
The method is illustrated through a study of healthcare use trajectories in a Swiss cohort of diabetic patients.

We propose a new procedure to take sampling uncertainty based on bootstraps. In each bootstrap, a new typology and regression are estimated. The bootstrap estimates are then combined using a meta-analysis framework.

#SequenceAnalysis is often used to create a typology of trajectories. This typology is then used in regressions to study the association between trajectories and covariates.

By doing so, sampling uncertainty, which affects both the typology and the regressions, is ignored.

This article develops and reviews methods for the creation of sequence analysis typologies in large databases, which rapidly faces computational issues. It proposes an extension of the CLARA clustering algorithm and discusses three approaches to measure the quality of the clustering.
