Which is the correct answer for the question below.
Some popular reality television programs follow people who buy the contents of abandoned storage lockers at public auctions. In most cases, several storage lockers are sold in sequence during a particular auction. Occasionally, one of the buyers will purposefully bid much more than the expected value of a particular storage locker in order to intimidate the other bidders. What is a plausible explanation for these excessive bids?
A. The excessive bids may be rational if they occur during the last auction of the day.
B. The bidder is trying to establish a first-mover advantage, but only if they occur during the first auction of the day.
C. The buyer is trying to establish a reputation that may affect the outcome of later auctions.
D. The excessive bids represent a form of tacit collusion among the buyers.
A power plant is planning to acquire a new Diesel generating set to replace its resent unit which they run during brownouts. The new set
would cost 130,000 with a five (5) year-life, and no estimated salvage value. Variable cost would be 140,000 a year. The present generating
set has a book value of 60,000 and a remaining life of 5 years. Its disposal value now is 6,000 but it would be zero after 5 years. Variable
operating cost would be 157,500 a year. Money is worth 10%. Which is profitable, to buy the new generator set or retain the resent set?

- Your answer is partially correct. An independent contractor for a transportation company needs to determine whether she should upgrade the vehicle she currently owns or trade her vehicle in to lease a new vehicle. If she keeps her vehicle, she will need to invest in immediate upgrades that cost $5,200 and it will cost $1,300 per year to operate at the end of year that follows. She will keep the vehicle for 5 years; at the end of this period, the upgraded vehicle will have a salvage value of $3,800. Alternatively, she could trade in her vehicle to lease a new vehicle. She estimates that her current vehicle has a trade-in value of $9,800 and that there will be $4,100 due at lease signing. She further estimates that it will cost $2,900 per year to lease and operate the vehicle. The independent contractor's MARR is 11%.

- A company is considering either (1) purchasing equipment for use on a new project (purchase cost = $5,000; purchase variable cost = $50 per day) or (2) leasing this equipment from a vendor at a rate of $100 per day. An initial analysis determined that the “purchase” option break-even point is 100 days. Based on this analysis, the company should Lease the equipment if the expected project is expected to last more than 100 days Purchase the equipment if the expected project is expected to last less than 100 days Purchase the equipment if the expected project is expected to last more than 100 days No answer text provided.arrow_forward4. "Family Man," a construction company, is considering whether to bid on a contract for a new housing complex. The cost of preparing a bid USD 200,000. “Family Man" has a 0.8 probability of winning the contract, if it submits the bid. If "Family Man" wins the bid, it has to pay USD 2000,000 to be a project partner of the project. As per the usual practice, "Family Man" will then consider consulting a market research firm "Marquess" to conduct a market survey to forecast the demand of housing complex before beginning the construction. "Marquess" charges a fee of USD 150,000. Now, the demand scenario can be either "High demand" or "Low demand." "Family Man" gets a revenue of USD 5000,000 and USD 3000,000 in case of "High demand" and "Low demand" scenario, respectively. On the other hand, instead of construction, "Family Man" has a provision of selling its project rights to another project partner construction company at the price USD 3500,000.

- A decision maker's worst option has an expected value of $1,000, and her best option has an expected value of $3,000. With perfect information, the expected value would be $5,000. What is the expected value of perfect information?arrow_forwardA young computer engineer has $12,000 to invest and three different investment options (funds) to choose from. Type 1 guaranteed investment funds offer an expected rate of return of 7%, Type 2 mixed funds (part is guaranteed capital) have an expected rate of return of 8%, while an investment on the Stock Exchange involves an expected rate of return of 12%, but without guaranteed investment capital. Computer engineer has decided not to invest more than $2,000 on the Stock Exchange in order to minimize the risk. Moreover for tax reasons, she needs to invest at least three times more in guaranteed investment funds than in mixed funds. Assume that at the end of the year the returns are those expected; she is trying to determine the optimum investment amounts. (a) Express this problem as a linear programming model with two decision variables.(b) Solve the problem with the graphical solution procedure and define the optimum solution.arrow_forward#6) A group of medical professionals is considering constructing a private clinic. If a patient demand for the clinic is high, the physicians could realize a net profit of $120,000. If the demand is low, they could lose $55,000. Of course, they do not have to proceed at all, in which case there is no cost. In the absence of any market data, the best the physicians can guess is that there is a 50-50 chance the demand would be high. a) Create a decision tree. b) What should the medical professionals do? What is the payoff? c) The physicians have been approached by a market research firm that offers to perform a study of the market at a fee of $5,000. The market researchers claim that their experience enables them to use Bayes’ theorem to make the following statements of probability: -probability of high demand given a positive survey result = 0.82 -probability of low demand given a positive survey result = 0.18 -probability of high demand given a negative survey result = 0.11…arrow_forward
