Explanation:

Game Theory is a branch of Economy that studies the decisions in which an individual could succeed if he or she takes into account the decisions of the rest of the participants involved in the event. Game Theory has also been applied for subjects such as Mathematics, Managements, Psychology or even Biology.

In the game theory, the Preemptive Strategy is implemented when individuals take a step before other participants in an attempt of having a favorable outcome of the situation. They lead the event using creativity. Thus, Wal-Mart used the preemptive strategy by opening stores in small towns that supported only one discount store.
