Child Endowments and the Quantity and Quality of Children

This paper brings together and integrates social interactions and the special relation between quantity and quality. We are able to show that the observed quality income elasticity would be relatively high and the quantity elasticity relatively low and sometimes negative, even if the true "unobserved� income elasticities for quantity and quality were equal and of average value. Moreover, the observed quality elasticity would fall, and the observed quantity elasticity would rise, as parental income rose.
