Minimum detectable effect size for main outcomes (accounting for sample
design and clustering)
Using Bloom's (2005) expression for the MDE, our estimate of the intracluster correlation from baseline data of 0.067, and an estimate of an average of 75 observations per bureaucrat, we estimate that a sample of 572 bureaucrats, or 42,882 observations, will allow us to detect a 5% effect with 95% probability.
