The manager of a funfair realizes that demand for rides is more elastic among males. He is evaluating different pricing stategies. The manager estimates the following demand curves:

Males: q=18-5p

Females: q=10-2p

Assume that a ride costs the funfair $2 each.

a) (10 pts.) If the market cannot be segmented, what is the uniform monopoly price?

b) (6 pts.) If the funfair can charge according to whether or not the consumer is a male but is limited to linear pricing, what price per ride should be set for each group?

c) (8 pts.) If the funfair can apply a block pricing strategy, what block price should the manager choose for each group? How many rides will each group be offered

Solutions

Expert Solution

a) In case the segmentation is not done, the demand function is added up

Q= (18 - 5p) + (10 - 2p)

=> Q= 28 - 7p

So, p = 4 - Q/7  

Total revenue = p.Q = 4Q - Q²/7

Therefore marginal revenue MR = 4 - 2Q/7

The Marginal cost is constant and equal to the cost Incurred to the funfair = 2

MR = MC

=> Q = 7

Now substituting Q in our demand equation, the uniform monopoly price = $3

b)

In this case, we need to solve for each demand curve separately. First case scenario: males

q = 18 - 5p

=> p = 3.6 - ⅕q

Total revenue = p.q = 3.6q - ⅕q²

Now Marginal revenue = 3.6 - ⅖q

And we know the constant marginal cost = $2

MR = MC

3.6 - ⅖q = 2

=> q = 4

Substituting q in the demand equation above, we get p= $2.8 which is the price set for male group

Similarly doing the math for females, we get the price to be set equal to $3.5

c)

In this case, let's take the demand in block 1 equals

q1 = 18 - 5p1

=> p1 = 3.6 - ⅕q1

And block 2 equals

q2 = 10 - 2p2

=> p2 = 5 - ½q2

As per the blocking price strategy, the revenue of block 1

= p1.q1

= 3.6q1 - 0.2q1² ....(1)

Revenue in the second block is given by price times the difference between quantities q1 and q2.

= p2. (q1 - q2)

= (5 - ½q2)(q1 - q2)

= 5q1 - 5q2 - 0.5q1q2 + 0.5q2² ...(2)

Total profits for the funfair equals to (1)+(2) - Total costs

Total costs = 2× q1 =2q1

= 3.6q1 - 0.2q1² + (5q1- 5q2- 0.5q1q2 + 0.5q2²) - 2q1

Taking partial derivatives with respect to q1 and equatiing it to 0 for profit maximizing we get

= 3.6 - 0.4 q1 + 5 - 0.5q2 -2 = 0

=> 0.4q1 + 0.5q2 = 6.6 ...i

Similarly taking partial derivatives w.r.t q2 and equating it to 0 we get

-5 - 0.5q1 +q2 = 0

=> q2 - 0.5q1 = 5 ....ii

q1 = 6.31 , q2 = 8.15

Respective prices for each group are

p1 = $2.34 p2 = $0.925

Hope this helps. Do hit the thumbs up. Cheers!
