In the textbook, we discussed the use of a Monte Carlo simulation in capital budgeting. A common application
of a Monte Carlo simulation is using it to determine the probability a
retirement portfolio will last for the duration of an individual's life.
However, as the article notes, it may be difficult for the average
investor to understand "the odds of success" or recognize the difference
between a 50 percent probability of success and a 70 percent
probability of success. One point the article makes that we would like
to reiterate is that flawed inputs can cause erroneous outputs. In other
words, like any other model, the end result is only as accurate as the
inputs.
