This paper estimates the longer-term effects of childhood conduct disorder on human capital accumulation and violent and criminal behaviour later in life using data of Australian twins. We measure conduct disorder with a rich set of indicators based on diagnostic criteria from psychiatry. Using...

A number of studies have shown that childhood speech impairments such as stuttering are associated with lower test scores and educational attainment. However, it is unclear whether this result is causal in nature or whether it can be explained by difficult-to-measure heterogeneity at the...

How much of the income-based gaps in cognitive ability and academic achievement could be closed by a two-year, center-based early childhood education intervention? Data from the Infant Health and Development Program (IHDP), which randomly assigned treatment to low birth weight children from both...
