Most students quickly grasp the concept of game theory–figuring out what your opponent is likely to do helps you decide what you ought to do. As this clip shows, however, failing to understand the real decision choices to be made can lead to deadly, but funny results. In class, after introducing simultaneous vs. sequential games, I show the clip, pausing it just before the 2:11 mark. At this point the poison is in the goblet, and I ask the students who haven’t seen the movie which goblet they think is poisoned. I record answers, and then show the clip (up to anywhere between 4:45 and 5:02). I then ask if they were surprised. I then show the remainder of the clip, and we discuss what mistake Vazinni made. Students see the real payoff matrix as: a) if I (Vazinni) guess wrong, I’m dead; b) If I guess right, then the Dread Pirate Roberts knows it too has incentive to kill me before he dies. I only live if Iocane powder kills instantly. My correct answer can only be not to drink either goblet if I want to live. After watching this video clip and class discussion, students can:
- identify what is a simultaneous decision
- identify the true payoffs in a payoff matrix
- understand the value of changing the game
- never get into a ground war in Asia (okay, just kidding about that one).

Managing change is given little time in most strategy courses. We often understate how difficult strategic change actually is and then wonder why organizations struggle so much with implementation (and our students think its all common sense). You can think of it as walking blindfolded on a tightrope between two solid foundations. During the transition, there is great uncertainty about whether the desired path is attainable. This, of course, is another way of looking at Lewin’s unfreeze/change/refreeze model. This video can help to illustrate the issue:

Economics-games.com is a free educational games site for teaching microeconomics, industrial organization and game theory. This site includes some simple (short) simulations designed to demonstrate specific principles. This should not be confused with longer simulations that extend across many class sessions. Instructors set up user IDs & passwords for their class and students are paired with others in the class (or even across universities if desired). These are really nice interactive online exercises that can be done between classes. In this sense, they are an excellent online complement beyond the usual readings and talking head videos. Here are some of the games:
- Cournot and Stackelberg games
- Public good financing game
- Common-pool resources game
- Prisoner’s dilemma
- Asymmetric matching penny game
- An air transport economics simulation covering price discrimination, vertical differentiation and peak-load pricing.
In addition, you may wish to check out some of their longer, commercial games (http://aireconsim.com).

Differentiation can be a challenge if existing products have identified the most central value propositions for customers. Increasingly, firms must differentiate using paths that may not follow others and there may be good reasons that rivals have left the path uncharted. Here is an example of differentiation whose time may not have come…

Presenting material clearly and concisely may not be the best way to help students learn. In fact, presenting ambiguous information that leverages common sources of confusion may be a much better route to learning. This post is intended to serve as a BLEG to solicit examples of confusions that students experience. Accordingly, this is a starting point for developing new material that draws on confusion to teach strategy. We begin by understanding what confuses students. Here are some examples that come to mind (please add your own examples in the comments):
- What does 5 Forces tell us about the firm’s advantage? Students often put a focal firm in the center and consider rivals to be substitutes. They don’t understand that the framework addresses the industry and not the firm.
- What industry to choose for 5 forces? Students often choose an umbrella industry instead of the specific segment they are considering entering (e.g., beer instead of micro brews in South Africa). The result, then, is almost useless for making decisions and the analysis is not used to make recommendations.
- Some resources are valuable while others are Inimitable (VRIO): Students think they are looking for some resources that fit in each bucket (V,R,I, & O) instead of a few resources that meet all of the criteria. They don’t understand that VRIO is a filter to evaluate all strengths in the value chain.
- What is that “O” for anyway (in VRIO)? It seems to make sense but students often don’t really understand how a firm can have all of the pieces and still not execute. I use Xerox PARC as an example.
- How do we make decisions using VRIO? Students often think they understand but don’t really know how to use it to make a decision. For example, how are capabilities relevant to decisions like entering new markets or fending off rivals?
- Motivation for diversification: guilty until proven innocent. Students often suggest that a firm should acquire a successful target. They fail to see that future success is built into the acquisition price and don’t ask why the buyer could create unique value over other bidders.
- Technology advantages erode rapidly. People see technology as key but miss that it can be easy to reverse engineer (leading to a temporary advantage). While the iPhone confers an advantage to Apple, Samsung has more market share.
- Core competence is not what a firm does well if rivals can do it better. Core competence must refer to VRIO resources in order to create value.
Again, please add your own examples in the comments below. The following TED talk by Derek Muller describes the technique in teaching science.

Ronnie Chatterji and Charlie Williams have put together an excellent research podcast series. They describe it as “Big ideas from business school professors.” It offers an excellent bridge between cutting edge business research and the world of practice. The podcast is sponsored by the Strategic Management Society (publisher of the Strategic Management Journal, Strategic Entrepreneurship Journal, and Global Strategy Journal). You can find the podcasts at iTunes, Soundcloud, and YouTube among other places. Want a quick taste? Here are some of the topics that this reviewer found especially interesting in the realm of entrepreneurship and innovation:

Early movers stand to lose if late movers learn from their mistakes and enter with better product offerings or better strategies. Classic early movers who lost include Osborne Computer Company (subsequently overtaken by Compaq) or EMI’s exit from the CT Scanner business. Myspace and AoL might also be counted among early entrants that ultimately fizzled.
That said, early movers can can gain key assets that make it hard for rivals to enter and compete. You may have noticed that “JebBush.com” takes one to Donald Trump’s home page and there are numerous other political misdirections along these lines for other candidates. Similarly, Tesla Motors has only just gained ownership of the Tesla.com domain (probably at a handsome price). In this way, there can be a race to secure resources and capabilities to take advantage of an opportunity and others are in competition for those resources even if the resources are firm specific (as candidate domains tend to be). From a scholarly standpoint, such resources can be approached from a variety of perspectives including strategic factor market theory, Coasean bargaining, or first mover advantages. Of course, there is a humorous side to all of this. SNL has captured this nicely in their spoof commercial for Dillon Edwards Investments (note that this may be a bit “saucy” for many classrooms but we’re all adults here).

Entry barriers are a critical element of Porter’s five forces framework. A key question is how firms get around the barriers. While the framework is at the industry level, a central part of the discussion is how the entry barriers might differ for different potential entrants. Some will have complementary resources or capabilities that make entry much easier. If a firm is considering entering a new industry, they want high entry barriers for all firms — except them. This sometimes sounds too good to be true until you discuss critical differences in resources and capabilities. This (admittedly silly) Doritos commercial from Superbowl 50 illustrates entry barriers and how some creative dogs get around them…

Nonsubstitutability is a critical resource attribute for sustaining a competitive advantage. Otherwise, a rival may find a different resource that can nullify an advantage without actually imitating the focal firm’s resource or capability. An example might be Apple’s iPhone patent for the “screen bounce” when the user scrolls to the bottom of a page or list. Early Android phones had the same feature but, more recent phones, work around this patent by displaying a blue tinge at the edge of the screen (see picture) when one has scrolled to the end. In this way, many patents do not confer an advantage as rivals find ways to work around them and customers don’t perceive a significant difference in the product. In class, one might give this example coupled with the video below which depicts a battle between Fezzik and Westley in the Princess Bride — agility and size can be discussed as substitutes in determining competitive advantage (of course, Westley wins though he at first seems to be at a disadvantage).

Here is another great whiteboard video from Shad Morris. This one focuses on how to evaluate the overall health of a country’s economy. This is important in assessing the business environment for strategic investment. Is a given market attractive? This might also lead into a nice discussion of comparative advantage of nations. If so, this might be another application of the Global Game exercise.

PEST analysis can be helpful to identify trends or factors outside of a firm’s focal industry that will ultimately affect the industry. It stands for Political, Economic, Socio-cultural, and Technological factors. PESTEL is a similar framework that adds Environmental and Legal trends to the mix. The PEST framework is simple but it has the advantage of focusing trend analysis efforts so you can cover ground in a more systematic fashion (than, for example, SWOT analysis which is quite unsystematic). Shad Morris’ video below offers a great introduction to the analytic framework.

Mattel just lost to Hasbro on producing Disney princess dolls — a $500M a year business. This brings to an end a 60+ year strategic alliance. A recent Bloomberg article tells the story of what happened and makes a nice start to a mini case. There are many facets to this that might be of interest in the classroom. Bargaining power is probably front and center. Mattel wanted to have their own princess line that they didn’t have to pay the substantial licensing fees to Disney. Once they were a competitor, Disney started to consider other options (an alliance or coopetition story). By seeking out Hasbro, Disney increased their options (BATNA to you negotiation buffs) and thus gained even more bargaining power. In the end, Hasbro had to work hard to present a fresh vision (including substantial firm-specific investments) but Disney still retains the power in the relationship. This also sends a signal to other Disney partners about reducing their commitment to Disney. Of course, Disney’s power is rooted in strategic assets (characters) and capabilities (to create more characters) so this brings in the resource based view (RBV) nicely. If you are in need of related comic relief, there are ample videos. Here are hipster princesses to get you started.
