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

Economists Examine File-Sharing and Music Sales
Get PDFThe decline in sales of music CDs and the recording industry’s attempts to reverse the decline have been much in the news over the last few years. Since this decline began at the same time that file-sharing became popular, and since file-sharing would be expected to lead to a decline in sales, file-sharing is the leading candidate among possible causes of this decline. At the center of the file-sharing debate is the empirical issue of whether or not file-sharing decreases sales. In this paper I examine the different empirical methodologies that have been chosen by economists studying this issue. The studies use different methodologies but nevertheless find, almost unanimously, that file- sharing has led to a serious decline in record sales, except for one highly publicized study that reaches very different, and in my opinion, highly implausible conclusions.mp3, filesharing, music, downloading, napster
Research Note--Testing File Sharing's Impact on Music Album Sales in Cities
No full textUsing a data set including album sales, Internet penetration, and various demographic measures for 99 American cities over the period 1998-2003, this paper empirically examines the extent to which file sharing has caused the U.S. decline in sound-recording sales over that period. Also examined is the impact of the Internet on entertainment activities so as to help cleanse the Internet penetration coefficient of that impact. The conclusion from this analysis is that file sharing appears to have caused the entire decline in record sales and appears to have vitiated what otherwise would have been growth in the industry.file sharing, peer-to-peer, copying, Internet, sound recordings, television, radio
