ou read about a traveling situation in which some airline passengers seem toget a “fast pass” through security and move effortlessly through the boarding process, while other passengers are waiting in long lines. In this example, the travellers who are moving quickly through the boarding process are probably: a) VIP passengers waiting longer more in an inconvenient lines b) Passengers who value time and convenience and are willing to pay additional fees for the privileges and other services c) Loyal passengers whom they knew beforehand in which line to go to avoid delays and inconveniences d) Government officials who are seated in the executive area

. When Chinese automakers began exporting cars, rather thanfocusing on developed nations in the West, they shippedautos to emerging markets in countries such as Algeria, Russia,Chile, and South Africa. In these markets, even used vehiclesfrom multinational manufacturers are relatively scarce—andrelatively expensive. The Chinese automakers, who prioritizelow cost rather than design or even safety, applied a penetration-pricing strategy. A woman in Santiago, Chile, who boughta new Chery S21 explained, “The price factor is fairly decisive.I paid $5,500 new and full. Toyota with similar features costsaround $12,000.” Why do you think Chinese automakerschose that pricing strategy? Do you think it was successful?As Chinese regulators pressure these manufacturers to maketheir cars safer, do you think they will be able to keep theirprices low compared with those of the international automakers? Why or why not?26
64. (This problem assumes knowledge of the basic rulesof baseball.) George Lindsey (1959) looked at boxscores of more than 1000 baseball games and foundthe expected number of runs scored in an inning foreach on-base and out situation to be as listed in the fileP09_64.xlsx. For example, if a team has a man on firstbase with one out, it scores 0.5 run on average untilthe end of the inning. You can assume throughout thisproblem that the team batting wants to maximize theexpected number of runs scored in the inning.a. Use this data to explain why, in most cases,bunting with a man on first base and no outs isa bad decision. In what situation might buntingwith a man on first base and no outs be a gooddecision?b. Assume there is a man on first base with one out.What probability of stealing second makes an attempted steal a good idea?
Consider the market for a single network good and suppose thatconsumers differ in their valuation of both the stand-alone and thenetwork benefits (it can indeed be argued that it is more plausiblethat a user who has a higher value for the stand-alone component of atechnology also assigns more importance to the size of its network.) Tocapture this idea, write the consumer’s utility function for joining thenetwork as U(θ) = θ(a + νne), where a is the stand-alone benefit, ν > 0measures the network effect, neis the expected number of users joiningthe network, and is uniformly distributed on the unit interval.a. What happens if p > a + νne? (Hint: Identify all consumer who buythe good for at price p and a given expected network size ne).b. What is the consumer’s willingness to pay for the nth unit of thegood when ne units are expected to be sold? Is the demand downwardsloping? Does the demand increase with the expected network size?c. Express the fulfilled-expectations demand curve…
True/False/Uncertain: 1. In taking an exam, Atack, a rational student, allocates his time to the various questions so as to equalize hismarginal point utility per minute on all questions. 2. The marginal utility of food to Zecher depends only on the amount of food (and not on the amount ofhousing) and the marginal utility declines as more food is consumed; likewise for housing. Therefore,both food and housing are normal goods. (Hint: Express the optimality condition for Zecher’s [UMP], MUF/MUH = PF/PH. Notice that PF/PH is fixed. If all of an increase in income is spent on F, can the equality be maintained?)
Let PX denote the price of product X (and likewise for other subscripts); M, the consumers’ income, and AX, the amount invested in advertising for product X (and likewise for other subscripts). If PY = 6; AZ = 50000; PW = 0.5, when graphing the demand function QDX = 3500 – 250PX – 280PY – 0.02AZ, what is the intercept of the Q-axis? Select one below. (A) 566.7667. (B)-13. (C) 820. (D)1050. 2. Imagine the market for Good X has a demand function of QDX = 40 – PX and a supply function of QSX = 2PX – 20. Suppose the current price of Good X (PX) is 30. Calculate consumer surplus (CS). CS = ________ 3. Imagine the tea market has a demand function of QDX = 10 – 2PX and a supply function of QSX = PX − 2, where PX is the price of the tea. Assuming the price is at equilibrium, calculate the equilibrium price (P*). P* = _________ 4. MacGuffins have a demand function of QD = 70 – P and a supply function of QS = 2P + 10.

Suppose that a large discount retailer with a lot of purchasingpower in a supply chain requires that all suppliers incorpo-rate a new information system that will reduce the cost of placing orders between the retailer and its suppliers as wellas between the suppliers and their suppliers. Suppose alsothat order quantities and lead times are related; the smallerthe order quantity the shorter the lead time from suppliers.Assume that all members of the supply chain use a continu-ous review system and EOQ order quantities. Explain the im-plications of the new information system for the supply chainin general and the inventory systems of the supply chainmembers in particular
If and the ui are non-atomic, show that there is a partition with ui(Ei) = αiui(Ω). Further, show that if everyone’s tastes are exactly the same, that is, if ui = uj for all i, j, then this gives the entire set of achievable utilities.
Suppose that the University of Alabama and Clemson are making spending decisions for theupcoming year. Assume that Alabama is currently spending $15 million on their recruiting andfacilities, and Clemson is spending $10 million. Each team has an additional $5 million to spendor keep as profits. If they both choose to not spend the additional $5 million then Alabama hasa 60% chance of getting the highest quality quarterback recruit to commit to them (getting thecommitment of the player is the goal). However, if they both choose to spend the additional $5million then there is a 57% chance that Alabama gets the high quality quarterback to commit. IfAlabama spends the additional $5 million but Clemson doesn’t then there is a 67% chanceAlabama gets the recruit. However, if Alabama does NOT spend the additional $5million butClemson does then there is a 50% change either team gets the recruit’s commitment. Setup thepayoff matrix and label the players, their strategies, and their payoffs, and…
Suppose you run a marketing survey and find you have two types of customers high-value customers willing to pay 16 and low-va consumers willing to pay just 10. Your survey tells you that there are equal numbers of high- and low- value customers. Obviously , have two possible options price high (16) and sell only to the high value group, or price low (10) and sell to everyoneThe costs incurred is 5 per unit and sales only happen to high -value consumers 50 % of the timeWhich price should you choose ? Select the correct response price high price low it depends price both high and low
Suppose, unfortunately, your mathematics andeconomics professors have decided to give teststwo days from now and you can spend a total ofonly twelve hours studying for both exams. Aftersome thought, you conclude that dividing yourstudy time equally between each subject will giveyou an expected grade of C in each course. Foreach additional three hours of study time for oneof the subjects, your grade will increase one letterfor that subject, and your grade will fall oneletter for the other subject.48 PART 1 • Introduction to EconomicsCopyright 2019 Cengage Learning.

You are evaluating the possibility that your company bids $150,000 for a particular construction job. (a) If a bid of $150,000 corresponds to a relative bid of 1.20, what is the dollar profit that your company would make from winning the job with this bid? Show your work. (b) Calculate an estimate of the expected profit of the bid of $150,000 for this job. Assume that, historically, 55 percent of the bids of an average bidder for this type of job would exceed the bid ratio of 1.20. Assume also that you are bidding against three other construction companies. Show your work.
a. A young connoisseur has $600 to spend to build a smallwine cellar. She enjoys two vintages in particular: a 2001French Bordeaux (wF) at $40 per bottle and a less expensive 2005 California varietal wine (wC) priced at $8. Ifher utility is U (wF, wC))=wF2/3 w C1/3 ,then how much of each wine should she purchase?b. When she arrived at the wine store, this young oenologistdiscovered that the price of the French Bordeaux hadfallen to $20 a bottle because of a decrease in the valueof the euro. If the price of the California wine remainsstable at $8 per bottle, how much of each wine shouldour friend purchase to maximize utility under thesealtered conditions?c. Explain why this wine fancier is better off in part (b)than in part (a). How would you put a monetary value onthis utility increase?
