Separations of romantic relationships are experienced differently by initiators and noninitiators.

Divorces are predominantly initiated by one spouse alone. This might suggest that one spouse typically benefits from divorce (the initiator), while the other is disadvantaged (the noninitiator). At the same time, empirical research on the consequences of divorce commonly focuses on the average effect for both partners. In contrast, I estimate separation trajectories individually for initiators and noninitiators of formerly cohabitating or married couples. The analysis covers a wide range of outcomes and a long period of time surrounding the separation. I employ an event-study design based on individual fixed effects, thereby accounting for time-invariant individual heterogeneity that could be linked to initiator status and the outcomes. The results reveal substantial differences in separation trajectories between initiators and noninitiators. Initiators indeed improve their subjective well-being after a separation and also see gains in other life domains, with the exception of the economic domain. Noninitiators experience significant short-term losses in subjective well-being, from which they recover in the long run. Noninitiators’ trajectories in other life domains vary.
