Abstract
In order to evaluate the relative importance of articles on Industrial Organization published in major generalist or specialized scientific journals, this empirical study has used the new 1991 JEL classification system, by regrouping contributions according to the type of article: theoretical analysis, industrial policy or industry studies. A rate of multiple reference index has been introduced to examine the degree of relation between these three categories and used as a proxy for editorial preferences towards the type of treatment of the subject usually expected by the journal. The article contents of nine generalist and five specialized journals are analysed for the two periods 1991–1995 and 1996–2000.
