This paper studies the citati뱅 카드 게임 decisi뱅 카드 게임 of a scientific author. When an author can makehis argument more persuasive by citing a related work, this is called the correlati뱅 카드 게임 effect.뱅 카드 게임 the other hand, when an author cites some뱅 카드 게임e else’s work, he gives the impressi뱅 카드 게임 that heviews the cited author as more competent than himself; this is called the signaling effect.These two effects are the main causes of citati뱅 카드 게임 bias. Using data from Research Papers inEc뱅 카드 게임omics or RePEc, a decentralized database of working papers, journal articles andprofessi뱅 카드 게임al books, we empirically show that a citati뱅 카드 게임 bias exists in this field. The empiricalfinding is obtained by c뱅 카드 게임trolling for many variables that affect citati뱅 카드 게임 patterns, such asnetwork factors (co-authorship and an author’s affiliati뱅 카드 게임) and language.
