Peer Effects in Academic Research: Senders and Receivers
利用法国全国性竞赛决定研究者地点的工具变量，发现学术中存在同伴效应，且发送者与接收者的专业、性别和年龄匹配至关重要，男性从其他男性获得的同伴效应是其他性别组合的两倍。
Abstract Using an instrument based on a national contest in France determining researchers’ location, we find evidence of peer effects in academia, when focusing on precise groups of senders (producing the spillovers) and receivers (benefiting from the spillovers), defined based on field of specialisation, gender and age. These peer effects are present even outside formal co-authorship relationships. Furthermore, the match between the characteristics of senders and receivers plays a critical role. In particular, men benefit a lot from peer effects provided by other men, while all other types of gender combinations produce spillovers twice as small. Part of the peer effects results from researchers switching research fields.
