Your editorial “The Child Allowance Welfare Trap” (Oct. 8) and Robert Doar’s online op-ed, “The Bad Science Behind the Child Tax Credit Expansion” (Oct. 29) question the evidence behind a 2019 consensus report from a nonpartisan committee of the National Academies of Sciences, Engineering, and Medicine (NASEM), on which we served. Rejecting the report’s conclusions, you and Mr. Doar cite estimates reported in a working paper released recently by Bruce Meyer and other University of Chicago researchers.
