Subjective Well-being and Partnership Dynamics; Are Same-sex Relationships Different?

Partnered individuals are happier than singles. This can be because partnership
leads to more satisfactory subjective well-being or because happier people are more likely to find a partner. We analyze Dutch panel data to investigate whether there is a causal effect of partnership on subjective well-being. Our data allow us to distinguish between marriage and cohabitation and between same-sex partnerships and opposite-sex ones. Our results support the short-term crisis model and adaptation theory. We find that marital partnership improves well-being and that these benefits are homogeneous to sexual orientation. The well-being gains of marriage are larger than those of cohabitation. Investigating partnership formation and disruption, we discover that the well-being effects are symmetric. Finally, we find that marriage improves well-being for both younger and older cohorts while cohabitation only benefits younger cohort.
