Assume the following game situation:
If Player A plays UP and Player B plays LEFT then Player A gets $1 and Player B gets $3.
If Player A plays UP and Player B plays RIGHT then Player A gets $2 and Player B gets $5.
If Player A plays DOWN and Player B plays LEFET then Player A gets $4 and Player B gets $2.
If Player A plays DOWN and Player B plays RIGHT then Player A gets $1 and Player B gets $1
What is the Mixed Strategy Equilibrium for Player B?
O. (LEFT, RIGHT) = (1/8, 3/8)
O. (LEFT, RIGHT) = (1/4, 3/4)
O. (LEFT, RIGHT) = (1/2, 1/2)
O. (LEFT, RIGHT) = (3/8, 1/8)

Suppose Colin's mom has decided to take him out to breakfast to celebrate his birthday. Colin is having a hard time deciding between breakfast combo #1 (3 pancakes and 2 scrambled eggs) and breakfast combo #2 (2 pancakes and 3 scrambled eggs) because they both sound equally good to him (and since his mom is paying for breakfast, he doesn't care about how much they cost). He ends up flipping a coin to decide which one to have. Which of following the statements are true? Select all that apply.
Breakfast combo #1 and breakfast combo #2 are on the same indifference curve for Colin.Breakfast combo #1 and breakfast combo #2 are on the same indifference curve for Colin.
Scrambled eggs and pancakes are perfect substitutes for Colin.Scrambled eggs and pancakes are perfect substitutes for Colin.
If Colin gets breakfast combo #1 his willingness to give up scrambled eggs for pancakes is likely to be lower than if he had gotten breakfast combo #2. If Colin gets breakfast combo #1…

- 1. Alizeh and Kelly were traveling together and have gotten stranded at an airport overnight. They have no cash, but they did both think to bring granola bars and turkey sandwiches with them. They currently each have several granola bars and a few sandwiches. Alizeh announces that she'd be willing to give up a granola bar for one turkey sandwich. Kelly responds that turkey sandwiches are bigger than granola bars so she would be willing to give up a granola bar if she could get half a turkey sandwich. Is Kelly and Alizeh's current allocation of granola bars and turkey sandwiches efficient? Explain why or why not. (Note that you cannot rely on a rule here – you have to specifically explain why the allocation does or does not meet the definition of an efficient allocation.)arrow_forward1arrow_forwardAssume the following game situation: If Player A plays UP and Player B plays LEFT then Player A gets $2 and Player B gets $4.

As an example, Samir is willing to drive 20 minutes out of his way to save $4 on a grocery item that costs $10 at a local market. But he is unwilling to drive 20 minutes out of his way to save $10 on a laptop that costs $400 at a local store. In percentage terms, how big is the savings on the grocery item? On the laptop? In absolute terms, how big is the savings on the grocery item? On the laptop? If Samir is willing to sacrifice 20 minutes of his time to save $4 in one case, shouldn't he also be willing to sacrifice 20 minutes of his time to save $10?arrow_forwardSuppose that you and a friend are playing cards and you decide to make a friendly wager. The bet is that you will draw two cards without replacement from a standard deck. If both cards are spades, your friend will pay you $7. Otherwise, you have to pay your friend $2. Step 2 of 2: If this same bet is made 543 times, how much would you expect to win or lose? Round your answer to two decimal places. Losses must be expressed as negative values.arrow_forward

- Suppose players A and B play a discrete ultimatum game where A proposes to split a $5 surplus and B responds by either accepting the offer or rejecting it. The offer can only be made in $1 increments. If the offer is accepted, the players' payoffs resemble the terms of the offer while if the offer is rejected, both players get zero. Also assume that players always use the strategy that all strictly positive offers are accepted, but an offer of $0 is rejected. A. What is the solution to the game in terms of player strategies and payoffs? Explain or demonstrate your answer. B. Suppose the ultimatum game is played twice if player B rejects A's initial offer. If so, then B is allowed to make a counter offer to split the $5, and if A rejects, both players get zero dollars at the end of the second round. What is the solution to this bargaining game in terms of player strategies and payoffs? Explain/demonstrate your answer. C.

Player 1 moves first. Player 2 observes player 1's actual move and then decides to move right or left. If player 1 moves right, player 1 receives £20 and player 2 receives £45. If both move left, player 1 receives £15 and player 2 receives £30. If player 1 moves left and player 2 moves right, player 1 receives £40 and player 2 receives £40. a. Draw the above situation in the form of an extensive form game. b. Find the sub-game perfect Nash equilibrium of the extensive form game.arrow_forwardRita is playing a game of chance in which she tosses a dart into a rotating dartboard with 8 equal-sized slices numbered 1 through 8. The dart lands on a numbered slice at random. This game is this: Rita tosses the dart once. She wins $1 if the dart lands in slice 1, $2 if the dart lands in slice 2, $5 if the dart lands in slice 3, and $8 if the dart lands in slice 4. She loses $3 if the dart lands in slices 5, 6, 7, or 8. (If necessary, consult a list of formulas.) (a) Find the expected value of playing the game. | dollars (b) What can Rita expect in the long run, after playing the game many times? O Rita can expect to gain money. She can expect to win dollars per toss. Rita can expect to lose money. She can expect to lose dollars per toss. O Rita can expect to break even (neither gain nor lose money).arrow_forward
