Fertilitätsentscheidungen im Partnerschaftskontext

A review of existing sociological literature on fertility decisions reveals that most empirical studies focus on characteristics of the female spouse as explanatory factors, while the role of the partner is neglected for the most part. However, most children are fathered and born into an existing relationship and the influence of the partner has to be regarded as an important determining factor for childbirth. We propose starting from a bargaining perspective and model family-formation as a collective decision mutually agreed upon by both spouses, especially scrutinizing on the interrelation of both partners' educational level. In this paper, we examine in how far certain educational constellations have an impact on family formation. Classical theories of family economics suggest that educational asymmetries between partners may encourage parenthood. Our analysis is based on German Mikrozensus data collected between 1996 and 2004. The large sample allows us to analyze in detail the effects of educational levels as well as uncommon educational constellations. In a first step, we investigate separate effects of general and vocational education of each partner, followed by a quasi-cohort design, with women born in the mid 1960th and mid 1970th, to study the timing of the first birth. We conclude that traditional hypergamy may foster parenthood. But also educational homogamy leads to a higher amount of parents as compared to hypogamous couples, in which the wife's educational qualification exceeds the husband's educational degree.
