The essence of this exercise is simple. Teams must build a device that will catch an egg dropped from 25 feet (e.g., a stairwell). The trick is that they must build it from items purchased in an auction. As such, items that are easy to use (e.g., an old pillow) are very expensive while items that are hard to imagine a use for (a brick) are cheap. Profit is determined by 1) succeeding in the task of catching an egg and 2) having the lowest cost function. As such, this demonstrates Barney’s (1986) notion of superior expectations in strategic factor markets.
Now that you see where this is going, here are the rest of the details.
Several factors might account for high prices including:
Here are 
In the Global Game exercise students are placed in groups with asymmetric resources with a task to maximize “points” produced. In order to maximize output, they need to trade resources (e.g., alliances) with other teams. The resources include raw materials (e.g., paper), technology (e.g., scissors and templates), knowledge (of the point system), and even people. They can also merge teams.
The key points are that managers deal with complex problems, and often use cognitive frameworks to help constrain the problems. These frameworks tell the managers what information is needed; however, unless the managers understand that all frameworks have limitations, these frameworks can fall trap to cognitive biases.
