Who Talks to Whom? Intra- and Interdisciplinary Communication of Economics Journals
研究了1995-1997年间42本经济学期刊之间以及经济学与人类学、政治学、心理学、社会学和五个商科学科的引用模式，发现经济学是其他社会科学和商科的重要知识来源，但自身很少引用其他学科。
Citation patterns between 42 journals in economics from 1995 to 1997 are examined, plus between economics and anthropology, political science, psychology, sociology and five business disciplines. Building on social network theory, we identify a hierarchical organization of journals in economics and seven journal clusters. Major citation flows are found from all areas of economics to the general interest and theory and method clusters, but not the other way around. Economics emerges as a significant source of interdisciplinary knowledge for the other social sciences and business. However, no area of economics appears to build substantially on insights from its sister disciplines.
