论文摘要
学者在研讨会和会议上介绍了他们的新研究，并向同龄人发送草稿，希望收到评论和建议，以提高其工作质量。本文使用在《经济学期刊》上发表的论文数据集，衡量了同行个人和集体评论的数量提高了研究质量。在控制研究思想和作者的质量时，我发现同龄人的个人和集体评论的数量增加了一个标准偏差，这增加了该研究发表的期刊的质量47％。
Scholars present their new research at seminars and conferences, and send drafts to peers, hoping to receive comments and suggestions that will improve the quality of their work. Using a dataset of papers published in economics journals, this article measures how much peers' individual and collective comments improve the quality of research. Controlling for the quality of the research idea and author, I find that a one standard deviation increase in the number of peers' individual and collective comments increases the quality of the journal in which the research is published by 47%.
