To evaluate the EMV, begin by listing the possible payoffs and noting that each outcome is equally likely. The payoffs are -1000, 0, 600, and 3000, and since there are four outcomes, the expected value is the average of these four numbers.
Option 1: 433. This would imply a sum of 433 × 4 = 1732 if it were the aver......Login to view full explanation登录即可查看完整答案

Note that that the probability that the stock market goes up is 75%. For this question only, we assume that this probability does not have to be 75%. What should this probability be such that the investor is indifferent between the choices in her decision? (Hint: Let p be the probability of U. Then the probability of D is (1-p). Find the value of p such that the EMV associated with B is the same as the EMV associated with S.)
Young screenwriter Carl has just finished his first script. It has action, drama, and humor, and he thinks it will be a blockbuster. He takes the script to every motion picture studio in town and tries to sell it but to no avail. Finally, ACME studio offers to buy the script for either $30,000 today or 1.75 percent of the movie’s profits. There are two decisions the studio have to make. The first is to decide if the script is good or bad; the second is to decide if the movie is good or bad. First, there is a 90 percent chance that the script is bad. If it is bad, the studio does nothing more and throws the script out. If the script is good, it will shoot the movie. After the movie is shot, the studio will review it, and there is a 60 percent chance that the movie is bad. If the movie is bad, the movie will not be promoted and will not make a profit. If the movie is good, the studio will promote it heavily; the average profit for this type of movie is $55 million. Assume Carl is risk neutral (i.e. not risk averse or risk loving), which one should Carl pick?
