Abstract
A large proportion of cohabitors in the Statistics Norway Omnibus Surveys of 1996 reported economic reasons for their hesitation to marry, and in particular the costs of the wedding. In line with this, the Norwegian Family and Occupation Survey of 1988 revealed effects both of women's cumulated income and men's non-employment on the actual choice of union type. Also some other evidence suggests that affordability matters, although there are plausible alternative interpretations. On the other hand, several estimates suggest that economic strength does not induce marriage. Since there also has been no deterioration of young adults' economic situation in Norway, except for the delay of economic independence owing to longer college enrolment, one can hardly claim that lack of affordability is a dominating force behind the massive drift away from marriage. The analysis is anchored in a theoretical framework that may prove useful in other studies of cohabitation as an alternative to marriage.
