In class, we have studied the fundamentals of game theory and several real-world situations which have been analyzed and/or predicted with game theory. In the article, Failing to Suspect Collusion in Price-Matching Guarantees: Consumer Limitations, Chatterjee, Heath, and Basuroy describe their experiment where they investigated how effectively consumers recognized collusive situations in retail environments.

In a previous post, rebelkingismyhero discussed a model of large scale networks called the random graph. A random graph/network is generated by connecting each pair of a number of vertices with some probability. This creates a graph with each vertex having the same connectivity or level of connectedness on average. rebelkingismyhero noted that […]

Game theory may help Tatas encounter CSN
Two prominent Indian steel companies, Tata Steel and Companhia Siderurgica Nacional (CSN) , are amidst a raging bid battle for Corus. Principles of game theory are drawn from both sides as each company devises its own strategy in the ascending bid auction that this business interaction has turned into. […]

While Enron’s stock continued to plummet from 2000 into 2001, Enron’s stockholders were encouraged to hold on to their stock and assured that the […]

Uncloaking Terrorist Networks
Modeling Terrorist Networks 
We have seen examples of networks and the application of theory to topics like traffic patterns and auctions. Though these topics are interesting and important in their own right, it isn’t always apparent how the study of networks can have a much more serious and deadly application: the study of international […]

An article on power in social networks in a business context.
When Unequals Try to Merge as Equals

Recently in class we’ve been talking about power in social networks. This article in the New York Times discusses a merger between XM Satellite Radio and Sirius Satellite Radio. The tricky part of this merger is that […]

We often assume that having many choices is a good thing, and this has been reflected in several settings we have looked at in class: if you are selling your house or auctioning an item, you do better if you have many potential buyers than if you have few; if you are negotiating on how […]

Last month, representatives from Palantir Technologies (which is indeed a reference to the Lord of the Rings object of the same name) held an information session at Cornell where they discussed two revolutionary data analysis tools.  One essentially creates networks out of the underlying structure and connections in data, using the methods by which the […]
