Warning about strategic manipulation of Internet forums appears in October Management Insights

Hanover, MD, October 16, 2006 – The danger of firms manipulating Internet-based opinion forums by posting anonymous messages praising their products is the subject of a paper in the Management Insights section of the October issue of Management Science, the flagship journal of the Institute for Operations Research and the Management Sciences (INFORMS®).

Management Insights, a new monthly feature of the journal, is a digest of important research in business, management, operations research, and management science. It appears in every issue of the monthly journal.

Strategic Manipulation of Internet Opinion Forums: Implications for Consumers and Firms by Chrysanthos Dellarocas examines policy decisions (is Internet forum manipulation socially harmful?), R&D decisions (does it pay to invest in technologies that discourage online manipulation? Who should bear the cost of such investments?), and firm and consumer attitudes towards Internet forums (how much should consumers trust online forums? How much should firms invest in trying to manipulate them?).

The October issue of Management Insights can be viewed online at http://www.atypon-link.com/INF/doi/abs/10.1287/mnsc.1060.0644. The full papers associated with the Insights are available to Management Science subscribers. Individual papers can be purchased at http://institutions.informs.org.
