We present evidence that the practice of holding back poorly performing students affects estimates of the impact of class size on student outcomes based on within-school variation of cohort size over time. This type of variation is commonly used to identify class size effects. We build a...

We use international student assessment data on more than 22,000 students from six European countries and a regression discontinuity design to investigate whether the transition into daylight saving time (DST) affects elementary students’ test performance in the week after the time change. We...

This paper examines the effects of Asian segregation on academic performance of non-Asian students in New York City public primary schools. We use plausibly exogenous variation in the share of Asian students stemming from a fertility shock among the Asian population in the year of the Dragon,...
