Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

Get PDFThe core industries of the new information economy are characterized by imperfect competition, asymmetric information or external effects. Thus, well-designed microeconomic policies, in the form of competition policies, technology policies or combinations of these, have strong potential of generating welfare improvements and promoting social efficiency. This paper emphasizes innovation-intensive competition, strong technological scale economies, network effects and complementarity between system components as characteristic features of the core industries in the information economy. With reference to these features the study explores the implications for microeconomic policies from the point of view of competition analysis. The combination of strong technological scale economies on the supply side and network effects on the demand side makes market structures with high concentration and dominant firms both likely and efficient. On the other hand, a firm possessing a dominant market position and operating in a network industry has access to a more efficient set of instruments in order to abuse its dominant market position relative to a firm operating in a traditional industry. This study argues that the recognition of these two counteracting aspects forms a necessary condition for the design of successful microeconomic policies in contemporary high-tech markets. It is also emphasized that efficient competition policy in these markets has to face an inherent structural trade-off between the exploitation of strong scale economies and the promotion of entry and small enterprises
