When playing roulette at a casino, a gambler is trying to decide whether to bet $10 on the number 30 or to bet $10 that the outcome is any one of the three possibilities 00, 0, or 1. 38 The gambler knows that the expected value of the $10 bet for a single number is - 53¢. For the $10 bet that the outcome is 00, 0, or 1, there is a probability of of making a ne 35 profit of $30 and a 38 probability of losing $10. a. Find the expected value for the $10 bet that the outcome is 00, 0, or 1. b. Which bet is better: a $10 bet on the number 30 or a $10 bet that the outcome is any one of the numbers 00, 0, or 1? Why? a. The expected value is $. (Round to the nearest cent as needed.) b. Since the expected value of the bet on the number 30 is than the expected value for the bet that the outcome is 00, 0, or 1, the bet on is better.

An investor with initial wealth W is given the opportunity to invest in a start-up (1) company. If the company does well, the investor will make a 200% profit in her investment, but if the company fails, the investor will lose all her investment. That is, if the investor invests X, she will get back 3x if the company succeeds and nothing if the company fails. The company will fail with probability 1/2 and will succeed with probability 1/2. The investor is risk-averse and has utility function u(x) wealth W should she invest in this company? Vx. What fraction of her initial

Monty Burns, the owner of the Springfield Nuclear Power Plant, owns many real estate properties. His last acquisition is a house worth €1,000, 000. Monty Burns considers purchasing an insurance for this new property. With probability 0.1, he will face damage reducing his property' value to €640, 000 while with probability 0.9 his property will not be damaged and thus will remain at its current value. Burns' vNM utility for wealth is given by u°(w) = Vw. Miss b runs an insurance company in Springfield and is willing to insure Monty Burns. The insurance contract says the following: if Burns' new property is damaged, she will pay an amount q (the coverage) to Monty Burns in exchange for a payment r (the premium) that is due independently from the occurence of the damage. Miss b's vNM utility over her income y is u°(y) = y. 1. Considering that Monty Burns actually buys insurance from Miss b, express the wealth of Monty Burns and the income of Miss b as functions of q and r. You have of…

A salesperson is trying to sell cars. The number of cars that she will sell depends on her effort "e" and her luck. Given her effort e, with probability 4e she is able to sell four cars, and with probability (1 - 4e) she is able to sell only one car. Her personal cost of effort is 100e². The dealership pays her a bonus b for each car sold. The salesperson is risk-neutral, and wants to maximize her expected utility, which is her expected income minus her effort cost. a) Given the bonus b, the salesperson's best response function is b) Suppose the dealership pays b = 2. Then the expected number of cars sold will be E(Q)=

The owner of a firm must hire a manager to launch a new product. The new product can be successful and generate a revenue of 5000 or fail and generate a revenue of 1000. The probability of succ success is 0.7 (and hence the probability of failure is 0.3). If the manager exerts low effort (e=e,) then the probability of success is 0.2 (and hence the probability of failure is 0.8). The manager's utility effort chosen by the manager, with D(e) = 10 and D(e)-o. The manager's reservation utility is -40 The wage paid by the owner to the manager is the owner's only cost. The owner is risk neutral. If the owner could observe the manager's effort and would want the manager to exert high effort, what contract would he offer to the manager? What is the own Assume from now on that the manager's effort is unobservable. Suppose that the owner still wants to ensure that the manager accepts the proposed contract an this to happen. c) a)? a) b) It can be shown that the constraints in point b) must be…

At races, your horse, White Rum, has a probability of 1/20 of coming 1st, 1/10 of coming 2nd and a probability of 1⁄4 in coming 3rd. First place pays $5,000 to the winner, second place $4,000 and third place $1,350.Hence, is it worth entering the race if it costs $1050?  Your company plans to invest in a particular project. There is a 40% chance you will lose $3,000, a 45% chance you will break even, and a 15% chance you will make $5,500.
