WebCluster-robust standard errors are now widely used, popularized in part by Rogers (1993) who incorporated the method in Stata, and by Bertrand, Du o and Mullainathan (2004) who pointed out that many di erences-in-di erences studies failed to control for clustered errors, and those that did often clustered at the wrong level. Cameron and Miller ... Clustered standard errors are often useful when treatment is assigned at the level of a cluster instead of at the individual level. For example, suppose that an educational researcher wants to discover whether a new teaching technique improves student test scores. She therefore assigns teachers in "treated" classrooms to try this new technique, while leaving "control" classrooms unaffected. When analyzing her results, she may want to keep the data at the student level (for …
