Economic theory suggests that selective immigration policies based on observable characteristics will affect unobservable migrant quality. Little empirical evidence exists on this hypothesis. We quantify traditionally unobservable components of migrant quality in Australia, a high-migrant share...

We test whether adverse childhood experiences - exposure to parental maltreatment and its indirect effect on health - are associated with age 30 personality traits. We use rich longitudinal data from a large, representative cohort of young US Americans and exploit differences across siblings to...

We develop and test an economic model of the cognitive and non-cognitive foundations of survey item-response behavior. We show that a summary measure of response behaviour - the survey item-response rate (SIRR) - varies with cognitive and less so with non-cognitive abilities, has a strong...

Internal locus of control (LOC) is a highly beneficial non-cognitive skill, yet its long-term formation process remains poorly understood. Using British cohort data, we examine the role that fathers play in LOC maturation from childhood into middle age; a machine-learning algorithm is used to...

We use a large, nationally-representative sample of working-age adults to demonstrate that personality (as measured by the Big Five) is stable over a four-year period. Average personality changes are small and do not vary substantially across age groups. Intra-individual personality change is...
