You work at a firm that makes fountain pens. The marginal cost of producing a fountain pen at your firm is given by the equation: MC = 5 + .01q The price people will pay for a fountain pen varies from year to year depending on what happens at the annual hipster convention. There, a buffalo nickle is flipped and in years when it lands "tails" up, the price of a fountain pen will be $50, however in all other years the price will be $40. Sadly, you must make your production decision before these coins are flipped. You do your best to maximize profits by setting E[MR] = MC, but you are always off a bit. What would be the value of changing the timing of your production run in order to know exactly what the price of a fountain pen will be?

You are invited to play a lottery. Entering the lottery costs $25 and you will receive an amount in return for the number you roll on a six-sided die, with you being entitled to $10 times the number you roll. Rolling a 1 pays $10, rolling a 2 pays $20, rolling a 3 pays $20, and so on. What is the expected value of entering this lottery?

$10 There are 6 possible outcomes. In two of them you lose money, in the other four you will make profits. The expected value comes from the sum of (payoff - 25)x(1/6) for each possible (10 - 25)x(1/6) + (20 - 25)x(1/6)+(30- 25)x(1/6)+(40 - 25)x(1/6)+(50 - 25)x(1/6)+(60 - 25)x(1/6) = $10

Suppose that Dave gets happiness from money according to the utility function U($) = $. This means that $25 worth of money gives him 25 units of happiness and $50 worth of money gives him 50 units of happiness. Suppose a casino lets him bet on the spin of a roulette wheel. He can bet $10 on black and will win $X if the ball falls in a black bin, or lose his $10 if the ball falls in either a red or green bin. Suppose further that there are are 24 possible black bins, 24 red bins, and two green bins. What is the minimum amount of money $x that Dave would need to win in order to be willing to play this game? Round your answer up to the nearest penny.

$10.84 He will lose 52% of the time and will win only 48% of the time. This means that he expects to lose $5.20 on any spin. His expected winnings must be just as large or larger to be willing to play. That means he must each x*(.48) = 5.2. Divide both sides by .48 to get x.

Casino War is a card game played with a single 52 card deck. The cards are ranked in the same way that cards in poker games are ranked, with aces being the highest cards. One card each is dealt to a dealer and to a player. If the player's card is higher, he or she wins the wager they bet. However, if the dealer's card is higher, the player loses their bet. A tie occurs when the dealer and the player each have cards of the same rank. In a tie situation, the player has two options: The player can surrender, in which case the player loses half the bet. The player can go to war, in which case the player must double his stake. If the player continues play in view of a tie, the dealer burns (discards) three cards before dealing each of them an additional card. If the player's card is ranked higher than the dealer's, then the player wins the amount of his original wager only. If the dealer's card is ranked higher than the player's, the player loses his (doubled) wager. If the ranks are equal, then the player wins the amount of his doubled wager. What is the expected value of betting $10 on this game if the player knows they will surrender in the event of a tie? Round all probabilities to the nearest whole number value (i.e. 46% or .46, not 46.2% or .46234)

-$0.30 There is a 3/51 chance of a tie. There is a (1-(3/51))/2 chance that you will win and walk away with your wager plus that of the dealer = $20, and a (1-(3/51))/2 chance you will lose and walk away with $0. In the event of the tie, you walk away with $5. No matter what, you are out the $10 you paid to play. You will expect to win $9.70, but since it will cost $10 to play, you expect to lose money.

The figure below shows the two potential demand curves and the marginal cost curve for the production of grapes by your vineyard. (image with green line DH at $3,000 P, Red DL at $1,000 and then MC from $500 to 600Q. Cross at 1000;100 and 3000;500) If the probability of demand being high, DH, is 40 percent and the probability of demand being low, DL, is 60 percent, what quantity of grapes maximizes your expected profit?

260 tons of grapes per year E[MR] = ($3,000 per ton x 0.40) + ($1,000 per ton x 0.60) = $1,800 per ton. This means that the vineyard should produce 260 tons of grapes per year, according to the marginal cost curve.

Both companies have similar technology that allows them to make hoverboards for $20 each. Neither firm has any fixed costs. The worldwide demand for hoverboards is pretty low now that they are known to catch fire.

If the price floor implemented is $80 per unit of corn, then the government will need to spend $80,000 to purchase all of the excess supply at that price.

Suppose that the market for corn in Atlantis, a small closed economy, can be described by the following demand and supply equations where P is the price per unit of corn and Q is units of corn: Demand: Q = 10,000 - 100P Supply: Q = 100P - 2,000 If the government of Atlantis decides to implement a price support program in this market, which of the following statements is false (holding everything else constant)? To be effective this price support program must implement a price floor that is greater than $60 per unit of corn. If the price floor implemented is $80 per unit of corn, then the government will need to spend $80,000 to purchase all of the excess supply at that price. If the price floor implemented is $80 per unit of corn, then consumer expenditure on corn will be equal to $160,000. All of the above are true

If the price floor implemented is $80 per unit of corn, then the government will need to spend $80,000 to purchase all of the excess supply at that price.

Suppose that Dave gets happiness from money according to the utility function U($) = $. This means that $25 worth of money gives him 25 units of happiness and $50 worth of money gives him 50 units of happiness. Suppose a casino lets him bet on the spin of a roulette wheel. He can bet $10 on black and will win $10 if the ball falls in a black bin, or lose his $10 if the ball falls in either a red or green bin. Suppose further that there are are 24 possible black bins, 24 red bins, and two green bins. How much would we expect playing this game would impact Dave's happiness?

It makes him 0.40 units less happy if he plays the game vs. not playing the game. He will lose 52% of the time and will win only 48% of the time. This means that he expects to lose $0.40 if he plays the game, which equates to .4 fewer units of happiness.
