## Question:

A decision maker is working on a problem that requires her to study the uncertainty surrounding the payoff of an investment. There are three possible levels of payoff — \$1,000, \$5,000, and \$10,000. As a rough approximation, the decision maker believes that each possible payoff is equally likely. But she is not fully comfortable with the assessment that each probability is exactly 1/3, and so would like to conduct a sensitivity analysis. In fact, she believes that each probability could range from 0 to 1/2.
a. Show how a Monte Carlo simulation could facilitate a sensitivity analysis of the probabilities of the payoffs.
b. Suppose the decision maker is willing to say that each of the three probabilities could be chosen from a uniform distribution between0 and 1. Could you incorporate this information into your simulation? If so, how? If not, explain why not, or what additional information you would need.
Monte Carlo simulation
Monte Carlo simulation is a technique used to understand the impact of risk and uncertainty in financial, project management, cost, and other forecasting models. A Monte Carlo simulator helps one visualize most or all of the potential outcomes to...
