Problem 1. [30 points] Consider the following decision tree. There are two parameters, p and Q, which are not known precisely. low base high p 10% 30% 50% Q 25k 30k 40k Conduct sensitivity analysis. First, determine the expected earnings as a function of the variables p and Q: E earnings of A = E earnings of B = E earnings of C = Second, determine the expected earnings using the base-case values for p and Q: E earnings of A = E earnings of B = E earnings of C = 2 Draw the one-way sensitivity plots for p and Q. Label the curves. Draw the tornado diagrams for strategies A and B. Label the axes. Draw the two-way sensitivity plot for p and Q. For each boundary denote which strategy is preferred and for each region denote the preferred strategy. 3 Problem 2. [20 points] The following questions involve calculating how money changes value over time. You do not need to calculate the final answer. You do need to simplify your answer so the quantity of interest is on the left hand side and all numbers are on the right. For instance, if asked to find a return rate r, your final answer should look like “r = . . . ” Recall the formula F V = P V (1 + r) n . A. 10 years ago, you invested $1000 in a savings account with 5% yearly compounded interest. Inflation has been stable at 2%. 1. What is the current dollar amount of your investment? 2. What is the current purchasing power in 2007 dollars? B. Your friend asks to borrow $10, 000. He says hell pay you back $5000 after five years and $7500 after 10 years. Suppose inflation is 2%. What is the net present value of this deal?
