Economics of Risk and Uncertainty Applied Problems
Problem 1:
A generous university benefactor has agreed to donate a large amount of money for student scholarships. The money can be provided in one lump sum of $12 million in Year 0 (the current year), or in parts, in which $7 million can be provided at the end of Year 1, and another $7 million can be provided at the end of Year 2.
Describe your answer for each item below in complete sentences, whenever it is necessary. Show all of your calculations and processes for the following points:
 Assuming the opportunity interest rate is 8%, what is the present value of the second alternative mentioned above? Which of the two alternatives should be chosen and why?
 How would your decision change if the opportunity interest rate is 12%?
 Provide a description of a scenario where this kind of decision between two types of payment streams applies in the “realworld” business setting.
Problem 2:
The San Diego LLC is considering a threeyear project, Project A, involving an initial investment of $80 million and the following cash inflows and probabilities:

Describe your answer for each question in complete sentences, whenever it is necessary. Show all of your calculations and processes for the following points:
 Describe and calculate Project A’s expected net present value (ENPV) and standard deviation (SD), assuming the discount rate (or riskfree interest rate) to be 8%. What is the decision rule in terms of ENPV? What will be San Diego LLC’s decision regarding this project? Describe your answer.
 The company is also considering another threeyear project, Project B, which has an ENPV of $32 million and standard deviation of $10.5 million. Project A and B are mutually exclusive. Which of the two projects would you prefer if you do not consider the risk factor? Explain.
 Describe the coefficient of variation (CV) and the standard deviation (SD) in connection with risk attitudes and decision making. If you now also consider your riskaversion attitude, as the CEO of the San Diego LLC will you make a different decision between Project A and Project B? Why or why not?
