This paper explores the use of instrumental variables analysis with a multisite randomized trial to estimate the effect of a mediating variable on an outcome.
Despite the growing popularity of the use of regression discontinuity analysis, there is only a limited amount of accessible information to guide researchers in the implementation of this research design. This paper provides an overview of the approach and, in easy-to-understand language, offers best practices and general guidance for practitioners.
An Analysis of the Interaction among Quality-of-Life Indicators from the New Communities Program Evaluation
This paper explores analytic methods that assess the rate at which changes in neighborhood quality of life occur. It looks at correlations among quality indicators over time and the effect of both neighborhood context and conditions beyond the neighborhood, like the Great Recession, identifying which indicators are predictors of others.
Using an alternative to classical statistics, this paper reanalyzes results from three published studies of interventions to increase employment and reduce welfare dependency. The analysis formally incorporates prior beliefs about the interventions, characterizing the results in terms of the distribution of possible effects, and generally confirms the earlier published findings.
