American Economic Journal - a peer-reviewed reliable source - has accepted the paper for publication. Any complaint now is "I disagree with the paper" (WP:IDONTLIKEIT) which is fine but not reason to censor it from inclusion on Wikipedia. There is no "undue weight" since it's a short paragraph in a long article, and makes every effort to frame it as the POV of a single paper and researcher. If you would like to debate the paper's conclusions find reliable sources that provide counter-POVs, rather than trying to delete it from the article.   C
