Seminar Description: 

In my last STIET talk (November, 2007) I reported some preliminary results for this project that concentrated on average impact of online access on journal citations ("Taller Profiles"). More than a year later (but it seems like years of work!), my co-author, Chris Snyder, and I are ready to report on a broader set of results based on better data and more robust econometric specifications. Before summarizing these latest results let me again describe the data: citation data from 1980-2005 to articles published between 1956 and 2005 in 300 journals in 3 disciplines: economics and business, general science and biology, and history. We exploit a natural experiment -- "online access" -- that occurred selectively over the period 1995-2005, to examine whether citation profiles and tails are taller and longer, respectively, and if so, whether these changes are correlated with specific content "channels", e.g. JSTOR, the geographic location of the citing authors, etc. Our results contradict the conventional wisdom in this area: 1. the average impact of online access is modest, not large, and limited to a handful of channels. 2. Online access does appear to substantially affect the distribution of *cited* articles, generating a "long tail effect". Furthermore, these results differ in important ways depending on the discipline and location of the citing authors. Related papers on 2-sided markets and scientific journals are available at http://www.si.umich.edu/~mccabe/.

Seminar Speaker Bio: 

Mark McCabe is a visiting assistant professor at the School of Information and a lecturer at the Stephen M. Ross School of Business.

After receiving his Ph.D. in applied economics from MIT's Sloan School of Management, McCabe joined the Economic Analysis Group in the U.S. Justice Department's Antitrust Division in Washington, D.C. While at the Department of Justice, his responsibilities included the analysis of anti-competitive practices, mergers, and federal economic regulation. During this time, he also served as an adjunct professor at American University.

From 1998 to 2007, McCabe was an assistant professor in the School of Economics at the Georgia Institute of Technology. His other affiliations include the Sloan Industry Studies Program and the State Center's Panel of Economists, and in the past the National Research Council.

McCabe's research in the field of industrial organization currently focuses on the economics of digital information goods markets (with a particular interest in scientific publishing) and the implications of the online environment for competition policy. This research has been published in various scholarly journals, including the American Economic Review, the Rand Journal of Economics, and Nature and has been supported by grants from the Andrew W. Mellon Foundation, the NET Institute, and the Open Society Institute. On occasion it has also been cited in publications such as Le Monde, Nature, the New York Times, Science, and the Wall Street Journal.
