Abstract
Cognitive and noncognitive skills determine many life outcomes, and so there has been significant research interest into the technology by which they are produced. We advance the state-of-the-art in this field by building upon the definitive contribution of Cunha, Heckman and Schennach (Estimating the Technology of Cognitive and Noncognitive Skill Formation; Econometrica, 2010). We develop that contribution by normalizing its production function, by nesting that production function, by relaxing over-identifying restrictions, and by amending several minor discrepancies within the code. These developments greatly improve the fit of the model, and they reverse some counter-intuitive findings that formerly emerged from it.
