Two firms compete in a market to sell a homogeneous product with inverse demand function P = 600 – 3Q. Each firm produces at a c

onstant marginal cost of $300 and has no fixed costs. Use this information to compare the output levels and profits in settings characterized by Cournot, Stackelberg, Bertrand, and collusive behavior.

Answer:

Explanation:

We need to find the function of firm 1 and firm 2 which we have as

PQ1/Q1= 300

600Q1– 3Q21 – 3Q1Q2/ = 300

300 – 6Q1 – 3Q2= 300

Q1 = 1/6(600 -300 – 3Q2)

Q1 = 50 – 1/2Q2 Reaction function for firm 1

Q2 = 50 – 1/2Q1 Reaction function for firm 2

Cournot which we have as;

Q2 = = 1/6(600 -300 – 3Q1)

Q2 = 50 – 1/2Q1

Q2 = 50 – ½(50 – 1/2Q1)

Q2 = 50 – 25 + 1/4Q1

Q1 = 100/3 = 33.33 Output

Q2= 100/3 = 33.33 Output

Equilibrium market price which is

P = 600 – 3(Q2+ Q2)600 – 3(100/3 + 100/3)= 400

Profits for firm 1

Π1 = TR1– C1= PQ1 – C1=400 * 100/3 – 300 * 100/3= 10000/3 = $3,333.33 For firm 1

Profits for firm 2

Π2 = TR2– C2= PQ2 – C2=400 * 100/3 – 300 * 100/3= 10000/3 = $3,333.33 For firm 2

Stackelberg is given as ;

QL= (600 – 300)/2*3 = 50 Firm 1 output is QL = 50

QF= (600 – 300)/4*3 = 25 Firm 2 output is QF =25 P = 600 – 3*75 = 375

Π1 = (375-300) * 50 = 3750Profit for firm 1

Π2 = 75*25 = 1875 Profit for firm 2

Bertrand is given as ;

Under this competition, price is the same to marginal cost and profits are zero

600 – 3Q = 300

Q = 100 Output = 100

P = Zero

Collusive Behavior is given as;

MR=MC600 - 6Q = 300

300 = 6QQ = 50 Output

P = 600 – 3*50 = 450

Π = (450 – 300) * 50 = 7,500profit

The city of New Orleans has 200 advertising companies, 199 of which employ designers of normal ability at a salary of $100,000 a
zepelin [54]

Answer:

a. $700,000

b. 6/7 or 85.7%

c. No they will not.

Explanation:

a. Jacobs will earn the normal salary that the other designers in the other companies are getting in addition to the incremental income he brings to the company as a result of his talents.

Incremental income = Revenue with Jacobs - Revenue without Jacobs

= 1,000,000 - 400,000

= $600,000

Jacobs earnings = Normal designer earnings + incremental income

= 100,000 + 600,000

= $700,000

b. Economic rent is the excess amount that the company is paying Jacobs over what it should normally cost to get a designer.

Normal cost of designer is $100,000. Company is therefore paying an economic rent of $600,000.

Proportion of Jacobs salary that is economic rent = \frac{Economic rent}{Jacobs annual earning}

= \frac{600,000}{700,000}

= 6/7 or 85.7%

c. The company hiring Jacobs will not be making an economic profit because for them to make an economic profit they would have to be making more than the $400,000 that the other firms make. They cannot make this amount because for them to do so they would have to reduce the amount they pay Jacobs. If they do so, Jacobs would leave for greener pastures and then they would be making the same $400,000 that the rest are making.

Chromatics, Inc., produces novelty nail polishes. Each bottle sells for 3.60. Variable unit costs are as follows:
devlian [24]

Answer:

Margin of safety= 9,000 units

Explanation:

Giving the following information:

Each bottle sells for 3.60.

Variable unit costs are as follows:

Acrylic base- .75

Pigments- .38

Other ingredients- .35

Bottle, packing material- 1.15

Selling commission- .25

Fixed overhead costs are 12000 per year. Fixed selling and administrative costs are 6720 per year. Chromatics sold 35000 bottles last year.

First, we need to calculate the variable cost per unit and total fixed costs:

Unitary variable cost= 0.75 + 0.38 + 0.35 + 1.15 + 0.25= $2.88

Total fixed costs= fixed overhead + fixed selling and administrative= 12,000 + 6,720= 18,720

Now, we can calculate the break-even point in units:

Break-even point= fixed costs/ contribution margin

Break-even point= 18,720 / (3.6 - 2.88)= 26,000 units

Margin of safety ratio= (current sales level - break-even point)

Margin of safety ratio= 35,000 - 26,000= 9,000 units
