The difference-in-difference method: Assessing the selection bias in the effects of neighborhood environment on health

Archived Abstract of Former PSC Researcher

Grafova, Irina B., Vicki Freedman, Nicole Lurie, Rizie Kumar, and Jeannette A. Rogowski. 2014. "The difference-in-difference method: Assessing the selection bias in the effects of neighborhood environment on health." Economics and Human Biology, 13(1): 20-33.

This paper uses the difference-in-difference estimation approach to explore the self-selection bias in estimating the effect of neighborhood economic environment on self-assessed health among older adults. The results indicate that there is evidence of downward bias in the conventional estimates of the effect of neighborhood economic disadvantage on self-reported health, representing a lower bound of the true effect.
