Notes: A variable x without a ′ refers to the parent and with a ′ refers to his child.

τ : AFQT Score

σ : Socialization

μ : Motivation - Job Aspiration

η : Self-Esteem (Rosenberg Scale)

ϕ : Internal Self-Control (Pearlin Scale)

The schooling level in column one refers to parents’ schooling level in all models. While for other models the attributes Socialization, Motivation, Internal Self-Control (Pearlin) and Self-Esteem (Rosenberg) in the first column are parents’ attributes, for schooling model s, these attributes in column one are the individual’s own attributes. Variable s in column one corresponds to parents’ education level and this model is estimated using the 1979 youth sample.
