Women and the Econometrics of Family Trees

We present an econometric structure for the analysis of intergenerational mobility that integrates non-linearities, the role of maternal-side effects and the impact of grandparents. We show how previously estimated models are special cases of this general framework and what specific assumptions each embeds. Our analysis of linked U. S. data 1900-40 reveals the extent to which inadequate consideration of assortative mating and the impact of mothers produces misleading conclusions.
