This isnt really a homework question but a question in general about what I am reading.

I am on page 34 in my econ book and I'm reading the "Linear Demand Curve" section. There is a section on this page that reads "As an example, consider the damand curve: Q= 8 - 2P..."

It then goes on to read "For this curve, DELTA(Q)/DELTA(P) is a constant and equal to -2 (a DELTA(P) of 1 results in a DELTA(Q) of -2).

The rest of the page goes on futher to confuse me.

Why is DELTA(Q)/DELTA(P) a constant and equal to -2? Where did the values in Figure 2.11 come from?

The government of Catalina Island is currently inviting investors to bid for the exclusive right to provide cable television service to its resident. The market demand for this service is P=55-0.01Q, where Q is the number of households that would subscrie to the cable service and P is the monthly fee charged to teh subscribers. The associated marginal revenue curve is MR=55-0.02Q. Universal Entertainment is interested in bidding for the right to provide cable service on Catalina Island. It has a constant average and marginal cost of $15 for providing cable service to each household.

a. if universal were to be awarded the excluse right to provide cable, how many households would it service? what price would it charge per household per month?

b. if they were to be awarded, how much profit would it earn?

c. what is the most universal entertainment would bid for the franchise?

d. at what level of output (numer of households) is uniersal entertainment's total revenue maximized?--- this is the one I really need help with. I think I have figured out the rest where Q=2,000 P= $35, profit= $40,000, and would bid $40,000... I can't figure out how to do this one part. Is it MR=MC and solve for Q? because that just gets me back to 2,000 or am I missing something more. Thank you for any assistance.

1. Alice lives in a town with only one movie rental store. Suppose Alice's demand for movie rentals per month is Q = 16 - 2P. The movie store currently charges $5 per movie but is thinking of adding a flat monthly cardholder fee and dropping the price to $2 per rental. At this new price, what is the largest cardholder fee that Alice will pay? If the rental store has a constant marginal cost of $2, which strategy is more profitable?

2. A monopolist faces a demand curve given by,

Y = 100 -Ā  P

with the inverse demand curve equal to,

P = 100- y and MR = 100- 2y.

The monopolist's total and marginal cost functions are,

TC = 700 + 20y and MC = 20.

a) Calculate the monopoly output level, the monopoly price, and the profits of the firm.

b) Draw a diagram to illustrate your answers to part a). Calculate the deadweight loss from this monopoly. [Hint: you need to work out the perfectly competitive quantity and price. The diagram will help you work out how to calculate the DW L using the simple geometry of triangles and rectangles.]

c) Explain why this market might be considered to be a natural monopoly.

d) Illustrate and explain the problem that emerges when the government regulates the monopolist by imposing marginal cost pricing.

e) If the government regulates the monopolist by imposing average cost pricing, what will be the monopolist's price and quantity? Draw a diagram to illustrate your answers. Explain the problem that exists with this average cost pricing. [Note: this is a trickier part than the others, so don't worry if you can't do it. If this question came up in the exam, I would miss out e) and have a)-d), making you feel a bit better! To answer it, you have to set p = AC and solve for output. It requires solving a quadratic equation with 2 potential output levels and working out which output level is the one the monopolist would produce. The quadratic equation is a simple one, but if you are not comfortable with maths, even its mention probably sounds like a nightmare.
