Fertility desires and fertility: Hers, his, and theirs

The relationship between desired and achieved fertility may be misspecified by excluding husbands' fertility desires or by confounding effects of shared desires with the resolution of conflicting desires. Using couple data from the classic Princeton Fertility Surveys, we find relatively large husband effects on fertility outcomes as well as unique effects of spousal disagreement. Wives and husbands were equally likely to achieve fertility desires, and disagreeing couples experienced fertility rates midway between couples who wanted the same smaller or larger number of children. These conditions do not hold, however, when we include willingness to delay births for economic mobility as part of the measure of fertility desires. Among couples who both wanted a third child, only husbands' willingness to delay births had significant negative effects on birth rates.
