Toys For U is developing a new Hannah Montana doll. The company has made the following assumptions:
■ It is equally likely that the doll will sell for 2, 4, 6, 8, or 10 years.
■ At the beginning of year 1, the potential market for the doll is 1 million. The potential market grows by an average of 5% per year. Toys For U is 95% sure that the growth in the potential market during any year will be between 3% and 7%. It uses a normal distribution to model this.
■ The company believes its share of the potential market during year 1 will be at worst 20%, most likely 40%, and at best 50%. It uses a triangular distribution to model this.
■ The variable cost of producing a doll during year 1 is equally likely to be $4 or $6.
■ Each year the selling price and variable cost of producing the doll will increase by 5%. The current selling price is $10.
■ The fixed cost of developing the doll (which is incurred right away, at time 0) is equally likely to be $4, $8, or $12 million.
■ Right now, one competitor is in the market. During each year that begins with four or fewer competitors, there is a 20% chance that a new competitor will enter the market
customers (last year’s purchasers) will buy a doll during the next year, and a fraction 0.2
0.04n of customers currently in the market who did not purchase a doll last year will purchase a doll from the company this year. We can now generate a prediction for year t sales. Of course, this prediction will not be exactly correct. We assume that it is sure to be accurate within 15%, however. (There are different ways to model this. You can choose any method that is reasonable.)
a. Use @RISK to estimate the expected NPV of this project.
b. Use the percentiles in @RISK’s output to find an interval so that you are 95% certain that the company’s actual NPV will be within this interval.
