We examine reported productivity changes of workers over the course of the Covid-19 pandemic, which we validate against external metrics. On average, workers report being at least as productive as before the pandemic's onset. However, this average masks substantial heterogeneity, which is linked...

We study an intensive math instruction policy that assigned low-skilled 9th graders to an algebra course that doubled instructional time, altered peer composition and emphasized problem solving skills.

Although the proportion of students enrolled in college increased in the last decades, students from non-college family backgrounds remain underrepresented in higher education around the world. This study sheds light on whether the provision of information in a randomized controlled trial with...

We use rich data on a cohort of English adolescents to analyse the long-term effects of experiencing bullying victimisation in junior high school. The data contain self-reports of five types of bullying and their frequency, for three waves of the data, when the pupils were aged 13 to 16 years....
