Jumping On The Bandwagon Effect
American Venture Magazine has an interesting article (from a bit ago) on the effect of “Bandwagons” (in other words information cascades) on the world of venture capitalism. Venture capitalist investments tend to not be taken lightly as investing in this sense is a very high-risk business. A great deal of research […]

The paper Imperfect Learning and Error Cascades in Sequential Guessing Games: An Experiment describes an experiment in which students played Chinos, a Spanish parlor game.

In a post by Andy Beal, entitled “Is Google’s Pay-Per-Action a Threat to Affiliate Networks?” Beal raises the notion that the emergence of Google’s new Pay-Per-Action product might come off as a challenge to any of the affiliate marketing networks. As mentioned in previous blog posts, with Pay-Per-Action (PPA), instead of paying per click […]

The topic of this research paper (Princeton University) is information cascades. The concepts are the same as many of the principles that we have gone over in class, however they are developed much further to explain phenomena observed in real situations. The experiments involve a simple scenario, with many decision makes, two choices, […]

The sudden and widespread attention given to the “Vote Different” video clip (also sometimes referred to as “Obama 1984″ or “Hillary 1984″ ) is a dramatic example of the sort of tipping phenomenon that the course is beginning to cover. On YouTube, the commercial has now been viewed almost 3 million times, which doesn’t […]

In this article, http://www.worldchanging.com/archives/005507.html, Ethan Zuckerman offers bloggers an overview and a review of Cass Sunstein’s book, Infotopia: How Many Minds Produce Knowledge.  The review is fairly long and covers a large amount of information and Sunstein’s argument about how today’s society aggregates information—for better of worse.  While I cannot cover all of Sunstein’s points, […]
