Abstract
A variety of external conditions may affect individual performance in high-stake cognitive assessments, with potentially lasting consequences on earnings and career. We provide the first causal evidence that the time of the day is an important condition affecting the performance at the moment of an evaluation. Exploiting a setting in which cognitive assessments are quasi-randomly assigned at a different time of day, we find that peak performance occurs in the early afternoon. The estimated time-of-day effects follow specific patterns consistent with the circadian rhythm, which suggests that biological factors are important determinants of performance even in economically meaningful settings.

AbstractThe paper examines the impact of class size on postgraduate (PG) grades using administrative data from one of the largest Schools of a Russell Group University in the UK. As well as estimating fixed effects models on the population of PG candidates in the School, we exploit a policy change aimed at reducing class size to implement a regression discontinuity design. We find that class size does impact overall grades adversely; and the policy aimed at reducing class size impacts grades favourably. Our findings are robust to alternative specifications as well as being supported by the validity tests we conducted.
