In randomized controlled trials, it is common for attrition rates to differ by lottery status, jeopardizing the identification of causal effects. Inverse probability weighting methods (Hirano et al, 2003; Busso et al., 2014) and estimation of informative bounds for the treatment effects (e.g. Lee, 2009;...

Academically focused tutoring programmes for young children have been promoted widely in the US in various forms as promising strategies for improving academic performance, particularly in reading and mathematics. A body of evidence shows the benefits of tutoring provided by certified, paid...
