摘要

Dahl and Lochner (2012) provides some of the first causal evidence of the effects of family income on child achievement using changes in the Earned Income Tax Credit. Unfortunately, a coding error in the creation of total family income affects the first stage estimates and inflates the instrumental variable (IV) estimates. Importantly, it does not affect the reduced- form estimates or alter statistical significance of the IV estimates. This response shows that correcting this error does not alter the core findings or main message of the paper.
