The (mis)estimation of neighborhood effects: causal inference for a practicable social epidemiology.
The resurgence of interest in the effect of neighborhood contexts on health outcomes, motivated by advances in social epidemiology, multilevel theories and sophisticated statistical models, too often fails to confront the enormous methodological problems associated with causal inference. This paper employs the counterfactual causal framework to illuminate fundamental obstacles in the identifica...
متن کاملCausal inference from longitudinal studies with baseline randomization.
We describe analytic approaches for study designs that, like large simple trials, can be better characterized as longitudinal studies with baseline randomization than as either a pure randomized experiment or a purely observational study. We (i) discuss the intention-to-treat effect as an effect measure for randomized studies, (ii) provide a formal definition of causal effect for longitudinal s...
متن کاملSharp bounds on the causal effects in randomized experiments with ‘‘truncation-by-death’’
Many randomized experiments suffer from the ‘‘truncation-by-death’’ problem where potential outcomes are not defined for some subpopulations. For example, in medical trials, quality-of-life measures are only defined for surviving patients. In this article, I derive the sharp bounds on causal effects under various assumptions. My identification analysis is based on the idea that the ‘‘truncation...
متن کاملWhat Do Randomized Studies of Housing Mobility Demonstrate?: Causal Inference in the Face of Interference
During the past 20 years, social scientists using observational studies have generated a large and inconclusive literature on neighborhood effects. Recent workers have argued that estimates of neighborhood effects based on randomized studies of housing mobility, such as the “Moving to Opportunity” (MTO) demonstration, are more credible. These estimates are based on the implicit assumption of no...
