AEM 424 PS #1 Answer Key 1. Software marketing. a. See attached decision tree. You have already developed the software, so that $2 million is a sunk cost (assuming you can’t see the software). Forget about it. The expected value of marketing the software is $3,350,000, which is greater than the expected value of not marketing, which is $0. So, not knowing whether or not Linux will succeed, the best you can do is to get $3,350,000 on average. Now suppose you know whether or not Linux will succeed. If Linux does succeed, a situation you will face with probability 0.7, you will chose to market with a profit of $5,000,000. If Linux does not succeed, a situation you will face with probability 0.3, you will chose not to market with a payout of $0. So, on average, you will get 0.7($5,000,000)+0.3($0)=3,5000,000. The value of knowing the information is thus the difference between the best you can do knowing and the best you can do not knowing: $3,500,000-$3,350,000=$150,000. If you could go back in time and reconsider the decision to develop the software, the value of the information would increase to $750,000. Use the same procedure to see this. 2. VC Decision Tree a. See attached decision tree. The highest EV is to prepare lightly with an average outcome of $12,000. b. The question asks what the option value of waiting to see the outcome of the first meeting before deciding how much to prepare for the second meeting. Obviously, if you prepare heavily for the first meeting, then there is no option value (nothing gained from delaying). So, you need to consider only the case in which you prepare lightly, and then prepare heavily if the first meeting fails. To do this, just change the probabilities and payouts in the “prepare light” VC#2 decision branch to the same as that of the “prepare heavy” VC#2 branch. The expected outcome of the VC#2 branch then rises from zero to $5,000 and the “light preparation” decision rises from $12,000 to $15,500 (0.3*$40,000+0.7*$5,000). Hence, you would pay up to $3,500 for the option to have the second meeting a week later. 3. Acme Steel Research (a) See figure 3a. (b) For the project to be successful, each of the three independent steps must be completed. Since the probability of success in each stage is 0.8 and the probabilities are

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
