Re: Profits from STARZ

We recently added the STARZ Network to our premium cable tier. Currently 852 of our basic service subscribers purchase this service at our current price of \$10.50 per month. As, you know, our current contributions from STARZ are not as high as expected. I would like you to evaluate our current price to see if we might be able to raise or lower it to enhance the contributions of STARZ to our revenues.

In an early study of the feasibility of adding STARZ, the marketing department obtained the attached data on the demand and costs for this channel in our Region 1 service area. In addition to the fixed administrative costs, there is a variable cost (license fee) of \$5.49 per customer. Please use these data to provide your recommendation about whether we should increase or decrease prices (from \$10.50 we are charging now) to increase total profits. I am particularly interested in
1)an estimate of our profit maximization price, and
2)an estimate of how much our monthly profit will increase if we adjust price to your recommended level.

2. Suppose a firm's demand curve is given by P=120-0.5Q. Find the (value of) price elasticity of demand when the price is \$100. Is demand elastic or inelastic.

3.The following is a list of four projects that Capital Corporation must choose from for
the coming year.
Project Project Price Annual Net Inflows
A 700,000 118,861
B 670,000 109,039
C 184,000 32,549
D 273,000 48,305

(a)Given a uniform rate of interest of 9% and a uniform life of the projects of 10 years each. Calculate the NPVs of each project.
(b)Should we choose projects A,C,D or Projects A, B, D. Explain.

Solution Summary

There are three problems. First problem explains the steps to find out the profit maximization price by developing demand equation by regression. Second solution describes the steps to find out point elasticity of demand. Third solution explains the steps to find NPV of the projects.
