Managerial Economics – 6005 Homework – chapter 5 5.1 Market Demand. Michael Kelso, a Wisconsin-based management consultant, has been asked to calculate and analyze market demand for a new video game that is to be marketed to retail (R) and wholesale (W) customers over the Internet. Kelso’s client estimates fixed costs of \$750,000 year for the product, and that licensing fees and other marginal costs will be \$20 per unit. The client has also provided Kelso with the following annual demand information: P R = \$62.50 - \$0.0005Q R P w = \$50 - \$0.002Qw A. Express quantity as a function of price for both retail and wholesale customers. Add these quantities together to calculate the market demand curve. Graph the retail, wholesale, and market demand curves for prices ranging from \$65 to \$35 per unit.
