- The Greer Tire company manufactures a new steel-belted radial tire to be sold through a national chain of discount stores. Because the tire is a new product, Greer’s managers believe that the mileage guarantee offered with the tire will be an important factor in the acceptance of the product. Let X = miles that the tires last: X~N(60,000 2,500) Find the mileage guarantee that ensures this company will repair no more than 15% of its product for free. Assume the distribution of tire mileage is normal.Suppose there are two people, Selma and Burak, who must split a fixed income of 200. The marginal utilities of income for Selma and Burak are as follows: MUs = 600- 2*Is MUB = 600- 4*IB where IS and IB are incomes of Selma and Burak respectively. What is optimal distribution of income if social welfare function is additive? Draw the MUof Selma and Burak in the Edgeworth box and show part (a). What is the optimal distribution if society values only the utility of Selma? What is the optimal distribution if society values only the utility of Burak? This example refers to ……… ………. rationale for income redistribution and it is Pareto ………….You and two other people are to place bids for an object, with the high bid winning. If you win, you plan to sell the object immediately for 10,000.(a) How much should you bid to maximize your expected profit if you believe that the bids of the others can be regarded as being independent and uniformly distributed between 7,000 and 10,000?(b) How much should you bid to maximize your expected profit if you believe that the bids of the others can be regarded as identical and uniformly distributed between 7,000 and 10,000?
- Consider an individual who is risk-loving instead of risk-averse. a. Is U(I) concave or convex?b. Suppose this person is offered an actuarially fair insurance product that guarantees her a certain income, E[I]. Graph the consumer surplus this person receives from buying this insurance as p, the probability of being sick, varies from 0 to 1. You should plot p on the horizontal axis and consumer surplus on the vertical axis.c. Suppose, finally, that this person is offered a subsidy (perhaps from her parents) for buying insurance so that, if she buys insurance, she will be guaranteed an income γ E[I], where γ >1. With the subsidy, insurance is now actuarially unfair in her favor. Graph how her consumer surplus (M) changes as p, the probability of being sick, varies from 0 to 1. [Hint: draw a coordinate plane with p on the x-axis and M on the y-axis.] Based on this graph, under what conditions is she least likely to buy the subsidized insurance?In a study of the relation between the expanding budget of an advertisement on a specific product (X) in thousands of pounds and the quantity sold (Y), in tons, of a product. A sample of the advertising budget and the quantity sold in eight successive months is drawn from one of the companies which are dealing in such a product and the following information is obtained.Group I nesting boxes were well separated from each other and well hidden by availablebrush. There were a total of 480 eggs in group I, of which a field count showed about275 hatched. Group II nesting boxes were placed in highly visible locations and groupedclosely together. There were a total of 874 eggs in group II boxes, of which a field countshowed about 272 hatched. Find a point estimate ˆp1 and ˆp2 for the proportion of eggsthat hatch in group I nest boxes and group II nest boxes. Let p1 and p2 be the populationproportion of hatched count in boxes I and II respectively. Find a 99% confidence intervalfor p1 − p2.(a) List the given information with appropriate symbols.(b) What is the probability distribution of ˆp1−pˆ2, difference between sample proportions?(c) Write the expression for the population mean of ˆp1 − pˆ2 distribution.
