Labour market performance of surviving relatives in the Netherlands: applying sequence analysis on SSD data

Summary
1. Introduction
2. Data & analysis methods
3. Results
Introduction
Changes in social security policy National Survivors Benefits Act (Anw) and recent
research Research questions
What routes and trajectories do survivors of bereavement adopt on the labour market after the event (typology)?
What routes and trajectories lead to withdrawal from the labour market and Anw - dependence
Discriminating effects
Sequence analysis in a nutshell
Sequence properties and general statistics
Most analysis methods focus on only one state or transition/event The average labour market career often contains multitudes of
states and transitions (E/UB/U) Sequence analysis offers the possibility to examine labour market
careers as a whole of states, transitions and events• # distinct states, events and transitions• Length / duration of distinct states (mean / total duration / duration of separate
spells)• Most common patterns / searching for particular patterns• Entropy, turbulence, complexity • Timing of events
Edit-distances• Hamming distance (substitution costs)• Optimal Matching (indel costs)
Quantified Common Attribute• Longest Common Prefix• Longest Common Suffix• Longest Common Sub-sequence• # of Distinct Sub-sequences• # Matching Sub-sequences
Sequence analysis in a nutshell
Pairs of sequences: distances, similarities and dissimilarities
Results
Operationalising and alphabet
- Research population: persons who have lost their partner in 2002-2003
- Sequences of the same length of 61 months: 12 months before the event (death of the partner), the month of the event and 48 months after the event
- Emphasising Anw- benefits as a separate state- Three integrated tracks of sequences
- Job - Benefits (AO/WW/WWB)- Anw benefits
- 65 years and older as a separate category for labour market state
Results
Operationalising and alphabet
Starting position:• working • inactive • receiving benefits• working with benefits• Other
Results
Operationalising and alphabet
- Construct sequence strings- Distinguish between the starting positions- Determine general statistics of sequence strings- Calculate distances between sequence strings
separately for every starting position- Find clusters of distances within every group with a
distinct starting position- Do a regression analysis with typology as dependent
variable

Working without any interruptions 11.2 47%

Work > inactive within 2 years after the event 1.5 6%

Results
Typology
Starting position: working
• There is an evident impact of the event on the labour market performance of the surviving relatives
• Gender differences in types of trajectories adopted• Significant differences in behaviour between survivors in different life course
phases• The starting position is of great importance for outcomes (typology)• Anw is being used by different groups of survivors:
- Long-term Anw assistance with little chance of reconnecting with the
labour market
- Complementary Anw-assistance
