Learning or experience curves are widely used to estimate cost functions in manufacturing modeling. They have recently been introduced in policy models of energy and global warming economics to make the process of technological change endogenous. It is not widely appreciated that this is a...

We demonstrate that heat inhibits learning and that school air-conditioning may mitigate this effect. Student fixed effects models using 10 million PSAT-retakers show hotter school days in years before the test reduce scores, with extreme heat being particularly damaging. Weekend and summer...

A large portion of the variation in wages and wage growth rates among individuals is due to "unobserved" heterogeneity, and the source of individual heterogeneity is typically attributed to data limitations and/or the unobservability of certain productivity related factors. In this paper we...

A large body of literature suggests that the first years of life are critical for long-term economic, health and social outcomes. However, the effect of public programs on early life skills formation is largely unknown due to data limitations. In this paper we use novel data from a large...

This paper explores the implications of measuring college productivity in two different dimensions: earning and learning. We compute system-wide measures using administrative data from the country of Colombia that link social security records to students' performance on a national college...

Two recent meta-analyses use variants of the Baily, Hulten, and Campbell (1992) (BHC) decompositions to ask whether recent robust growth in Aggregate Labor Productivity (ALP) across twenty-five countries is due to lower barriers to input reallocation. They find weak gains from measured...
