In teaching industry analysis, I always make a point of discussing network effects as a potential barrier to entry (see Peter Klein’s comment to this post on the term “network externalities”). Usually, I use an example like the iPhone FaceTime application which increases in value depending on the number of family and friends who have iPhones. This, in turn makes it hard for rivals to enter because of the need for a large installed base. Google+ is another example in it’s failure to make much of a dent in Facebook’s market. Now, a new app gives discount points to students for locking their phones based on the number of other locked phones in the same vicinity. As such, when the whole class locks down using the PocketPoints app, they all get discount points. This pushes everyone to adopt the same app to get the most points and makes it hard for a competitor to enter. This might also be a nice way to turn the class into a lab to study game theory, or incentives. It does all this and keeps people off their phones in class! The following video describes the app.

However, it is certainly produced a gush of news lately as oil prices have slipped by 60% in just a few months. 
Rejection, almost inevitable, doesn’t deter them. The rest of us kill inventive ideas before we even test them because we fear rejection. 
An emerging literature focuses on learning from failures — both in terms of entrepreneurship and strategy more broadly. For some recent examples, see studies by 
MicroTech is a negotiation over the terms to transfer a technology between 2 divisions of a company to take advantage of a market opportunity. Sub-optimal agreements (money left on the table) represent transaction costs and inefficiencies that must be overcome in order to create corporate value. There are two roles (Gant and Coleman). One division, Household Appliances (HA), has developed a new technology that has value if sold outside of the company. However, the division does not have a charter to sell chips. In order to take advantage, the technology must be transferred to the Chips & components (CC) division. In the process, about 20-40% of the potential value is typically left on the table. The discussion focuses on how to align objectives and achieve cooperation across divisions. It turns out that such cooperation is hard to achieve in a competitive culture. How, then, can the firm create a cooperative culture? This, it turns out, may be a VRIO resource…

The “Vision Thing” exercise is designed to help students distinguish the activities of leaders and managers in a fun and engaging manner. The exercise involves creating a three-tiered hierarchical structure. One person is the CEO, another is the manager, and a third is the employee. The CEO prepares a vision statement in advance and works with the manager to determine how to translate the vision to a tangible “product” using the toy construction set. The manager then guides the employee on building the “product.” The process is iterative in nature—the manager can communicate with the CEO and employee as often as necessary. But there is a finite amount of time available to implement the vision. Once the exercise is complete the team comes together to examine how close the team came to implementing the CEO’s vision. The learning objectives are:

They have offered $600 million more for Family Dollar than the preferred suitor. Two things may be preventing Family Dollar from switching partners: 1) concerns that a Dollar General deal would be thwarted by anti-trust regulators, and 2) the Family Dollar CEO would lose his job if Dollar General takes over. Of course, they say the second issue is not on their minds. This makes a great “ripped from the headlines” case (
