This paper develops a model of skill formation that explains a variety of findings established in the child development and child intervention literatures. At its core is a technology that is stage-specific and that features self productivity, dynamic complementarity and skill multipliers....

In contemporary America, racial gaps in achievement are primarily due to gaps in skills. Skill gaps emerge early before children enter school. Families are major producers of those skills. Inequality in performance in school is strongly linked to inequality in family environments. Schools do...

This paper studies the influence of family, schools and neighborhoods on life-cycle earnings inequality. We develop an earnings dynamics model linking brothers, schoolmates and teenage parish neighbors using population register data for Denmark. We exploit differences in the timing of family...

This paper discusses (a) the role of cognitive and noncognitive ability in shaping adult outcomes, (b) the early emergence of differentials in abilities between children of advantaged families and children of disadvantaged families, (c) the role of families in creating these abilities, (d)...

We use Danish register data to investigate whether the effects of schoolmates' gender and average parental education on individual educational achievement, employment and earnings vary with individual family characteristics such as the gender of siblings and own parental education. We find that...

This study explores relationships between parental resource trajectories and child development, and their implications for intergenerational mobility. By modifying the child skill formation technology to incorporate new skills during adolescence, we analyze the importance of the timing of family...

We propose a twin family model linking twins with their spouses and children to quantify the relative importance of genetic and environmental factors in explaining the variance of socio-economic outcomes. Using data from the Danish Twins Registry and population registers, we test and relax the...
