Regression discontinuity: Take the Chile schools example from Section 21.3 and perform a series of analyses using different subsetting ranges. Plot the estimate ± standard error as a function of the subsetting range. As the width of the range increases, the standard error should go down, but there should be more of a concern about the use of the estimate for causal inference, given the lack of overlap.
