Couples' early career trajectories and later life housing consequences in Germany: Investigating cumulative disadvantages.

Using data on couples from the German Socio-Economic Panel (1995–2018), this study investigates how couples' early career trajectories affect housing outcomes in early adulthood and how this effect is mediated by couples' joint cumulative income. We apply a life course perspective by identifying dynamic treatments consisting of couples' consecutive employment statuses and examining their longer-term effects on homeownership and income shares spent on rent. Using multichannel sequence and regression analysis, we find that couples in which both partners have insecure employment trajectories, characterized by frequent spells of fixed-term employment and unemployment, are 25 percentage points less likely to own a home in early adulthood compared to couples with more secure career trajectories. Surprisingly, the couples' cumulative income does not remarkably mediate this effect, explaining less than one-fifth of the total effect. For couples who do not own their home but rent, we find that couples with insecure careers spend between 2 and 5 percentage points more of their joint income on rent compared to couples where both partners have secure career trajectories. Cumulative income disadvantages mediate the effects on shares of income spent on rent and reduce the effect sizes by 30–40%. Our findings indicate that inequalities caused by early career patterns can accumulate not only over time but also within couples and transfer to other areas of life, exacerbating housing and wealth inequalities in the longer run. • Multichannel sequence analysis reveals cumulative career (in)security in couples. • Insecure career trajectories decrease the probability to own a home in later years. • Disadvantages in cumulative income are not an important mediator for this effect. • Non-dual stable career couples spend higher shares of income on rent in later years. • Cumulative income mediates the effect of career instability on income spent on rent.
