This paper examines data on the institutional backgrounds of editors and authors of the top 30 economics journals, identified by their 1995 citation impact. It is revealed, for example, that 70.8% of the journal editors were located in the United States, and twelve U.S. universities accounted for the location of more than 38.9%. Concerning journal article authors, 65.7% were located in U.S. institutions and twelve U.S. universities accounted for 21.8%. Arguably, the degree of institutional and geographical concentration of editors and authors may be unhealthy for innovative research in economics. The number of academic journals in economics is large and increasing rapidly. The Judge Institute (1994) compiled a list of no less than 1,431 journals in management and social science, a large proportion of which were devoted to economic issues.2 Given this rapidly growing abundance of titles, more and more attention is being devoted to the identification of, and greater relative status bestowed upon, the top 30 or 'core' journals in the subject. It is likely that the explosion in the number ofjournals will lead to much higher relative prestige being bestowed on work published in the perceive 'core'. Accordingly, questions of institutional affiliation and control relating to these 'core' journals are of major and increasing importance. A list of the 30 most visible and well-known economics journals is compiled here. It is shown that a large number of the editors and authors related to these journals come from a few, predominantly U.S.-based, academic institutions. Although the degree of institutional concentration revealed here may be surprising, some might wish to attempt to explain this phenomenon by supposing that
