- Pricing Decisions at Madison The Madison Company manufactures and retails a certain product. The company wants to determine the price that maximizes its profit from this product. The unit cost of producing and marketing the product is 50. Madison will certainly charge at least 50 for the product to ensure that it makes some profit. However, there is a very competitive market for this product, so that Madisons demand falls sharply when it increases its price. How should the company proceed?2 In the pricing model in Example 7.1 with the constant elasticity demand function, the assumption is that all units demanded are sold. Suppose the company has the capacity to produce only 200 units. If demand is less than capacity, all of demand is sold. If demand is greater than or equal to capacity, only 200 units are sold. Use Solver to find the optimal price and the corresponding profit. Then use SolverTable to see how sensitive these answers are to the production capacity, letting it vary from 170 to 230 in increments of 10. Discuss your findings relative to the original solution in Example 7.1. In other words, what is the effect of capacity on the optimal price and profit?Assume the demand for a companys drug Wozac during the current year is 50,000, and assume demand will grow at 5% a year. If the company builds a plant that can produce x units of Wozac per year, it will cost 16x. Each unit of Wozac is sold for 3. Each unit of Wozac produced incurs a variable production cost of 0.20. It costs 0.40 per year to operate a unit of capacity. Determine how large a Wozac plant the company should build to maximize its expected profit over the next 10 years.Michelle owns a house in which she keeps valuables worth 100,000 which can get stolen with probability 1%. She can purchase coverage C of the amount C ∈ [0; 100,000] at premium π = 0.05 dollars for each dollar covered. Her Bernouilli utility function is u(w) = ln(w). Assume she has no other assets. 1. Set up her maximization problem. 2. How much insurance will she choose to buy? 3. How much profits does the insurance company earn on insuring Michelle? 4. Does the fact that the insurance company earn profits mean that Michelle is worse off com-pared to the situation in which she is not insured? Explain what is happening. 5. How much insurance will she buy if insurance companies charge an actuarially fair insurance rate?
- Suppose that a dam was built at a very high cost. At the time of construction, the estimated cost energy produced by the dam was £10 per unit. Of these £10, £5 contributed to the amortization of the initial investment and the other £5 to the variable recurrent cost. Now suppose that after the completion of the investment, a new energy source is discovered that allows the production of energy at a cost of £7 per unit. Should the dam be abandoned in favour of the alternative energy source? Please elaborate on your answer.Suppose my utility function for asset position x is givenby u(x) ln x.a Am I risk-averse, risk-neutral, or risk-seeking? b I now have $20,000 and am considering the follow-ing two lotteries: L1: With probability 1, I lose $1,000.L2: With probability .9, I gain $0.L2: With probability .1, I lose $10,000.Determine which lottery I prefer and the risk premium of L2.Xolani has just completed matric and has enrolled at a University in Cape Town, tocomplete a BCom Degree.

- Larissa Warren, the owner of East Coast Yachts, has been in discussions with a yacht dealer in Monaco about selling the company’s yachts in Europe. Jarek Jachowicz, the dealer, wants to add East Coast Yachts to his current retail line. Jarek has told Larissa that he feels the retail sales will be approximately €8 million per month. All sales will be made in euros, and Jarek will retain 5 percent of the retail sales as commission, which will be paid in euros. Because the yachts will be customized to order, the first sales will take place in one month. Jarek will pay East Coast Yachts for the order 90 days after it is filled. This payment schedule will continue for the length of the contract between the two companies. Larissa is confident the company can handle the extra volume with its existing facilities, but she is unsure about any potential financial risks of selling yachts in Europe. In her discussion with Jarek, she found that the current exchange rate is $1.34/€. At this exchange…Condo Construction Company is going to First NationalBank for a loan. At the present time, the bank is willing to lendCondo up to $1 million, with interest costs of 10%. Condobelieves that the amount of borrowed funds needed during thecurrent year is normally distributed, with a mean of $700,000and a standard deviation of $300,000. If Condo needs to borrowmore money during the year, the company will have to go toLouie the Loan Shark. The cost per dollar borrowed fromLouie is 25¢. To minimize expected interest costs for the year,how much money should Condo borrow from the bank?6. A farmer wants to start growing broiler chickens on his farm. he realizes that he needs to start with 8000 birds.

- Mamma Temte bakes six pies a day that cost $2 each to produce. On 31% of the days she sells only two pies. On 39% of the days, she sells 4 pies, and on the remaining 30% of the days, she sells all six pies. If Mama Temte sells her pies for $5 each, what is her expected profit for a dayʹs worth of pies? [Assume that any leftover pies are given away.]A purchasing agent for a particular type of silicon wafer used in the production ofsemiconductors must decide among three sources. Source A will sell the siliconwafers for $2.50 per wafer, independently of the number of wafers ordered. Source Bwill sell the wafers for $2.40 each but will not consider an order for fewer than3,000 wafers, and Source C will sell the wafers for $2.30 each but will not acceptan order for fewer than 4,000 wafers. Assume an order setup cost of $100 and anannual requirement of 20,000 wafers. Assume a 20 percent annual interest rate forholding cost calculations.c.
