In a “homogeneous goods” duopoly, two firms, Rooler Inc. and AFG are fierce competitors. The market demand is given by P = 200 – 0.9Q1 – 0.9Q2. Q1 denotes Rooler Inc.’s output, and Q2 denotes AFG’s output. The marginal cost of each firm is 17.

a) Given this market demand function, what is Rooler Inc.’s profit-maximising quantity if AFG produces 60 units (in 1,000s)?

Q2 = 60
P = 200 – 0.9Q1 – 0.9 × 60 = 146 – 0.9Q1
The corresponding marginal revenue is:
MR = 146 – 1.8Q1
17 = 146 – 1.8Q1
129 = 1.8Q1
Q1 = 71.67 = 71,667 units

In a “homogeneous goods” duopoly, two firms, Rooler Inc. and AFG are fierce competitors. The market demand is given by P = 200 – 0.9Q1 – 0.9Q2. Q1 denotes Rooler Inc.’s output, and Q2 denotes AFG’s output. The marginal cost of each firm is 17.

Determine Rooler Inc.’s so-called “reaction function”.

P = (200 – 0.9Q2) – 0.9Q1
Therefore:
MR = (200 – 0.9Q2) – 1.8Q1 = 17
183 – 0.9 Q2 = 1.8 Q1
Q1 = 101.67 – 0.5Q2

In a “homogeneous goods” duopoly, two firms, Rooler Inc. and AFG are fierce competitors. The market demand is given by P = 200 – 0.9Q1 – 0.9Q2. Q1 denotes Rooler Inc.’s output, and Q2 denotes AFG’s output. The marginal cost of each firm is 17.

Compute the Cournot equilibrium quantities and price in this market.

Q2 = 101.67 – 0.5Q2
1.5Q2 = 101.67
Q2 = 67.78 = 67,778 units
P = 200 – 0.9 × 67.78 – 0.9 × 67.78
P = 78

Your employer, a pharmaceutical company, has a patent on a specific antibiotic. The inverse demand function for that drug is as follows: P = 800 – 4Q. Marginal cost is constant and equal to 100.
Use the inverse elasticity pricing rule IEPR to determine the profit maximising price and quantity. Clearly indicate your method and approach to the solution.

P = 800 – 4Q
Q = 200 – 0.25P
Therefore:
= – 0.25 x (P/Q) = – 0.25P/(200 – 0.25P )
since Q = 200 – 0.25P we obtain:
(P – 100) / P = -1 / [ – 0.25P/(200 – 0.25P ) ]
P – 100 = (200 – 0.25P ) / 0.25
0.25P – 25 = 200 – 0.25P
0.5P = 225
P = 450
Now we substitute P = 450 into the demand function:
Q = 200 – 0.25P = 200 – 0.25 x 450 = 200 – 112.5
Q = 87.5

Which-one(s) of the following statement(s) is/are correct?

I. Under the conditions of perfect competition, the supply function calculates the quantity a supplier is willing to produce in function of the selling price as well as the cost of the input factors needed for production, and the cost of complementary goods and/or substitutes.
II. Given everything else is held constant, an increase in the cost of labour leads to upward shift of the supply curve. Mathematically, this corresponds to a higher intercept.
III. An increase in the cost of the input factors has no effect on the supply curve because the market price decides, which quantity a firm is willing to supply

Statements I and II are correct.

All three statements are correct.

Given are the following denotations:
MPL : marginal product of labour

PK : price of capital

If a firm wants to maximise output per monetary unit of input cost, then, given a two-factor production function with labour and capital, the following condition must hold: MPL = MPK .

If a firm wants to maximise output per monetary unit of input cost, then, given a two-factor production function with labour and capital, the following condition must hold: MPL/PL = MPK/PK .

If a firm wants to maximise output per monetary unit of input cost, then, given a two-factor production function with labour and capital, the following condition must hold: MPL × PL = MPK × PK .

Which one of the following statements is correct?

Under the conditions of perfect competition, firms are price takers only if they must lower their price to sell more units.

Under the conditions of monopolistic competition, in the absence of price discrimination, marginal revenue is not constant. It increases if more units are produced and sold at the market price

Under the conditions of perfect competition marginal revenue is equal to average revenue.

In your new job, you are responsible for the cost management in the production of a newly designed garden swing seat. Your predecessor has already worked on this project before you. She identified the following supply function:
QSx = –220 + 2.8Px – 10 W
QSx : quantity supplied
Px : selling price for one unit
W : wage per hour

Explicate the meaning of the term “+ 2.8Px “ in the above quoted supply function.

If the unit price increases by $1, then the supplier is willing to increase production by 2.8 units.

Identify the supply function for an hourly wage of $25.

QSx = –220 + 2.8Px – 10 W
QSx = –220 + 2.8Px – 8 × 25 = –220 + 2.8Px – 250 = –470 + 2.8Px
