This is an example of Russo and Schoemaker 1989 Scenario 1 A person enters a clock and a watch like $ 70. I will buy when a person says: "Two blocks away selling the same watch for $ 40 dollars" (the quality is the same, the two businesses are legitimate, and so on. Ceteris Paribus) Result: 90% of people will the second store to purchase the watch at a lower price. Scenario 2 A person enters an electronics store and you like a VCR for $ 800. Going to buy when a person says, "Two blocks away selling the same VCR to $ 770 dollars" (the quality is the same, the two businesses are legitimate, and so on. Ceteris Paribus) Result: Only 50% people will the second store to buy it. Why, in both cases the saving is $ 30? What do you think?

But what happens when the benefit of one is necessarily another's loss? I added a zero-sum problem.
A situation in which to win, another must lose. Consider the following matrix. It is a perfect example of a zero-sum game for two players. How it works: The first player (Red) secretly chooses one of two actions 1 or 2. The second player (blue), without knowing the choice of Red, secretly choose one of three actions: A, B and C. Elections are revealed and each player is affected by the coordinate scores generated by both elections. Example: Red chooses action 2 and Blue chooses action B. Red and Blue won 20 lost 20 points.
The winner is whoever gets the most points. As n'mro should seek to maximize the points to win. What should I do? Red thinks that: "With the action in February, could lose up to 20 points and win only 20, whereas an action I can lose and gain only 10 to 30, so that the action one is certainly better." With similar reasoning, choose action C. Blue If this happens, Red will win 20 points. But what if Blue Red anticipates reasoning and choose the option B? Or Red anticipates this move and choose Action 2? Try it … Franco Salzillo m
