Score contribution per author:
α: calibrated so average coauthorship-adjusted count equals average raw count
I ask whether the writing quality affects a research paper’s impact. Using papers published in the American Economic Review between 2000 and 2009 I apply a standardized readability metric to score the quality of the writing of the introduction section of each paper. Using citation counts to measure research’s impact, I show a statistically significant relationship between the two. The hardest to read papers suffer a reduction in citations by up to 15 of a standard deviation.
