Why Don't Struggling Students Do Their Homework? In a new study we use a field experiment to identify a structural model of learning.

We find that low productivity, not low motivation, is the stronger predictor of academic struggles. Study is available here: ideas.repec.org/p/feb/framed...

The G7 is exempting American multinationals from the global minimum tax. It’s pathetic and scandalous.

Cognitive skills are commonly assumed to begin deteriorating from the age of 30, which could pose a significant challenge for rapidly ageing populations. But this assumption relies largely on cross-sectional data that cannot distinguish between ageing patterns and cohort differences. Using German longitudinal data, this column finds that skills, on average, increase markedly into one’s 40s before decreasing slightly in literacy and more severely in numeracy. In addition, skills decline at older ages only for those with below-average skill usage, outlining a clear policy pathway for avoiding skill declines.

Cognitive skill decline with age is not as strong as previous studies suggest. Skills decline in old age only for those with below-average skill usage - use it or lose it.

Question about std errors:
In an RCT, treated people are randomly assigned to "pods" and interact (e.g., treatment = WhatsApp group membership). The norm (e.g. Cai-Szeidl) is to cluster on indiv for control group + on pod for treatment group. Why is clustering needed if any ICC is due to treatment?
