You and I play the following game. Hidden from you, I put a coin in my hand: with probability p itis a 10 pence coin and otherwise it is a 20 pence coin. You now guess which coin is in my hand:you guess it is 20 pence with probability s and otherwise you guess it is a 10 pence coin.You get to win the coin if you guess correctly and otherwise win nothing. What (in terms of p ands) is your expected gain in pence from playing this game once with me?Challenge: suppose we are going to play repeatedly and you want to maximise your gain and Iwish to minimise my loss. What value of p should I choose and what value of s should youchoose? (This question is somewhat ill-defined, but it does have an interesting possible answer.)(Note: anything labelled "challenge" will not be part of the hand-in.)

Given Information- P(putting 10 pence coin in hand) = p P(putting 20 pence coin in hand) = 1 - p…

Game Theory Consider the entry game with incomplete information studied in class. An incumbent politician's cost of campaigning can be high or low and the entrant does not know this cost (but the incumbent does). In class, we found two pure-strategy Bayesian Nash Equilibria in this game. Assume that the probability that the cost of campaigning is high is a parameter p, 0 < p < 1. Show that when p is large enough, there is only one pure-strategy Bayesian Nash Equilibrium. What is it? What is the intuition? How large does p have to be?

You and your roomate are deciding whether to go to a party or not on Friday. Going to the party is fun and gives a benefit of 4. If you go to the party, there is a 50% chance you will get covid. If you do not attend the party but your roommate does and gets covid, there is 80% chance that you will get covid. The impact of getting covid is -10. If both of you stay home, you will not be exposed to covid and will not have fun, leading to a payoff of 0 for both of you. 3. Construct a game matrix based on the description above and find any (c) Nash equilibria. How would your answer change if one roomate was less social and enjoyed (d) partying less than the other? Change the payoff matrix in a way that is both consistent with one roommate being less social than the other and changes the prediction you found in (a). (Note: if you found multiple possible equilibria in (a), changing the outcome could mean either making one of your prior Nash equilbria the only Nash equilibrium or making an…

Suppose that Alex and Bob complete the project sequentially. Assume that Alex decides his effort level and starts the project first, and then Bob decides his effort level and finishes the project. Present the extensive-form representation of the game (i.e., draw a decision tree which is also referred as the game tree). What is your prediction regarding the outcome of the game? Explain your prediction.
Here is a Bayesian BOS game. Man has a special preference t1 on boxing while woman has a special preference t2 on opera. Both are in [0,2]. The preference information is private. i.e. Each knows his (her) own preference but does not know the other's preference. The below is the payoff. M/W Boxing Opera Воxing 3+t1,1 0,0 Opera 0,0 1,3+t2 We are checking whether the below strategy profile is a Bayesian Nash Equilibrium. "Man chooses boxing if t1>p while woman chooses opera if t2>g." 1) Given t1, man will choose boxing if t1> /g- 2) Given t2, woman will choose opera if t2> /p- 4) By shoving the simultaneous equations, we get p=q=sqrt(6)-
Player 1 and Player 2 will play one round of the Rock-Paper-Scissors game. The winner receives a payoff +1, the loser receives a payoff -1. If it is a tie, then each player receives a payoff zero. Suppose Player 2 is using a non-optimal strategy: he/she plays Rock with probability 35%; Paper with probability 45%; and Scissors with probability 20%. Given that Player 1 knows Player 2 is using this strategy, the best response of Player 1 is to play O a mixed strategy with probability 1/3 each (Rock, Paper and Scissors) O Scissors with probability 100% O any strategy (any strategy is a best response for Player 1) O Rock with probability 100% O Paper with probability 100%

1.a) If the three executives of a fraudulent organization report nothing to the authorities, each gets a payoff of 100. If at least one of them blows the whistle, then those who reported the fraud get 28, while those who didn’t get -100. Suppose they play a symmetric mixed-strategy Nash equilibrium where each is silent (does not report fraud) with probability p. What is p?A, 0.1B, 0.28C, 0.5D, 0.8 b) In a two-player game, with strategies and (some known and some unknown) payoffs as shown below, suppose a mixed-strategy equilibrium exists where 1 plays C with probability 3/4, and Player 2 randomizes over X, Y, and Z with equal probabilities. What are the pure-strategy equilibria of this game? A, (A, Y) and (B, X)B, (A, Z) and (C, Y)C, (B, X) and (C, X)D, (C, X) and (C, Y)
3. Suppose we play the following game. I give you $100 for your initial bankroll. At each time n, you decide how much of your current wealth to bet. You cannot borrow money. You can only play with the money I gave you in the beginning or any money that you have won so far. The game is simple. At each time n ≥ 1, you decide the amount to bet. I will roll a fair die. If the die comes up 1,2,3,..., or 5, you win; if the die comes up 6, then you lose. IOW, if you bet $10 on the first roll, you will either have $90 or $110 after the first roll. (a) Suppose you wish to maximize your profit on the first roll. How much should you bet? (Most of you will get this wrong.) (b) What is the expected profit on the first roll if your bet is b with 0 ≤ b ≤ 100? (c) Suppose you wish to maximize your expected profit on the first roll. How much should you bet? (d) Suppose you wish to maximize your expected profit betting on the nth roll. How much of your current wealth do you bet? (e) Let X₂, be your…

Max Pentridge is thinking of starting a pinball palace near a large Melbourne university. His utility is given by u(W) = 1 - (5,000/W), where W is his wealth. Max's total wealth is $15,000. With probability p = 0.9 the palace will succeed and Max's wealth will grow from $15,000 to $x. With probability 1 - p the palace will be a failure and he’ll lose $10,000, so that his wealth will be just $5,000. What is the smallest value of x that would be sufficient to make Max want to invest in the pinball palace rather than have a wealth of $15,000 with certainty? (Please round your final answer to the whole dollar, if necessary)
