5. Reducing the bandwidth in an RD design generally increases the internal validity of the resulting estimate, and generally: A. B. C. D. decreases the external validity decreases the precision of the estimate. decreases the standard error of the estimate. increases the likelihood that the parallel trends assumption holds. Which of the research designs that we studied requires that your data be a 6. panel or repeated/rolling cross-section? A. Random Assignment B. Instrumental Variables C. Difference-in-Differences D. Regression Discontinuity Which necessary assumption for an instrumental variables analysis to be internally valid is hardest to prove because it is fundamentally untestable? 7. A. Inclusion Restriction (aka Relevance) B. Exclusion Restriction C. Full Compliance D. No heaping
