We econometrically evaluate the performance effects of a six month e-learning programme in a large retail chain with monthly data on sales revenue, for four years using panel regressions. Participants in early cohorts show positive performance effects during training periods that depreciate...

Causal inference in the empirical sciences is based on counterfactuals. This paper presents the counterfactual account of causation in terms of Lewis's possible-world semantics, and reformulates the statistical potential outcome framework and its underlying assumptions using counterfactual...

We study the impact of COVID-19 school closures on differences in online learning usage by regional academic performance. Using data from Google Trends in Italy, we find that during the first lockdown, regions with a previously lower academic performance increased their searches for e-learning...

To reduce cheating in written tests and exams, assessors often randomly vary the order of questions across students. However, little is known about the potential unintended side effects of question order. This paper examines whether randomizing students to start with an easier or harder question...

This paper examines whether family and community migration experience affect theprobability of high school graduation in Mexico once unobserved heterogeneity is accountedfor. Bivariate random effects dynamic probit models for cluster data are estimated to controlfor the endogeneity of education...

Attending kindergarten (KG) has been shown to have persistent benefits, but the peer effects of KG remain largely unexplored. We fill this gap in the literature by using nationally representative panel data on a cohort of middle-school students (grade 7) in China. We demonstrate that when peers...

Over the past decades, many European countries have raised the minimum legal drinking age (MLDA) from 16 to 18 years. This study provides novel evidence of the impact of this policy on educational outcomes by exploiting the staggered timing of MLDA changes across Spanish regions. Raising the...

We used data collected during the COVID-19 pandemic to examine how Italian upper secondary schools organized their activities for remote learning (RL). We conducted a three-level survey, administering questionnaires to each institution's students (11th and 13th graders, 11,154 students), 3,905...
