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.
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.
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.
This paper provides practical guidance for researchers who are designing studies that randomize groups to measure the impacts of educational interventions.
This paper provides a detailed discussion of the theory and practice of modern regression discontinuity. It describes how regression discontinuity analysis can provide valid and reliable estimates of general causal effects and of the specific effects of a particular treatment on outcomes for particular persons or groups.
Time Use Estimates for Economically Disadvantaged and Nondisadvantaged Married Couples in the United States
Contrary to some expectations, economically disadvantaged couples spend slightly more time together than nondisadvantaged ones, and more of that time is spent in leisure activities, according to this paper from the Supporting Healthy Marriage Project. While these couples may face different barriers to participating in voluntary programs than higher-income couples, their “time crunch” appears to be no worse.
Camden During Receivership
This working paper gives a broad overview of redevelopment efforts under the first term of state receivership in Camden, New Jersey. It concludes that attempts to build public capacity to revitalize cities may need to be complemented by efforts to build civic capacity, or the ability to solve problems in coordination with major partners.
This report presents a preliminary analysis of the cost of operating Britain’s Employment Retention and Advancement (ERA) demonstration, which is being evaluated though a large-scale randomised control trial. This assessment of costs will become an important element of the full cost-benefit analysis to be presented in future ERA reports.
Empirical Guidance for Studies That Randomize Schools to Measure the Impacts of Educational Interventions
This paper examines how controlling statistically for baseline covariates (especially pretests) improves the precision of studies that randomize schools to measure the impacts of educational interventions on student achievement.
