Exercise 1.3. Alice (Player 1), Bob (Player 2), and Charlie (Player 3) play the following simultaneous game. They are sitting in different rooms facing a keyboard with only one key and each has to decide whether or not to press the key. Alice wins if the number of people who press the key is odd (that is, all three of them or only Alice or only Bob or only Charlie), Bob wins if exactly two people (he may be one of them) press the key and Charlie wins if nobody presses the key. (a) Represent this situation as a game-frame. Note that we can represent a three- player game with a set of tables. Player 1 chooses the row, Player 2 chooses the column and Player 3 chooses the table (that is, we label the rows with Player 1's strategies, the columns with Player 2's strategies and the tables with Player 3's strategies). (b) Using the game-frame of part (a) obtain a reduced-form game by adding the information that each player prefers winning to not winning and is indifferent between any two outcomes where he/she does not win. For each player use a utility function with values from the set {0,1}. (c) Using the game-frame of part (a) obtain a reduced-form game by adding the information that (1) each player prefers winning to not winning, (2) Alice is indifferent between any two outcomes where she does not win, (3) conditional on not winning, Bob prefers if Charlie wins rather than Alice, (4) conditional on not winning, Charlie prefers if Bob wins rather than Alice. For each player use a utility function with values from the set {0,1,2}.

Imagine you are the mayor of a town and you are trying to decide if you should pay for a fireworks show. Your staff survey your 400 citizens who say that they each value a fireworks show at $10. The fireworks show only costs $3,000 so you put on the show but when you ask for donations to pay for the fireworks you only receive $25 total. What does this result show? Select an answer and submit. For keyboard navigation, use the up/down arrow keys to select an answer. You staff's survey must have overestimated the value of a fireworks show. b The fireworks cost must have been greater than their economic benefit. The firework show suffered from the Tragedy of the Commons problems d The town's citizens were free-riders.
