Question:
A monopoly firm has a total fixed cost of Rs 100 and has the following demand schedule:

Quantity

1

2

3

4

5

6

7

8

9

10

Marginal

Revenue

100

90

80

70

60

50

40

30

Find the short run equilibrium quantity, price and total profit. What would be the equilibrium in the long run? In case the total cost is Rs.1000, describe the equilibrium in the short run and in the long run.

Answer:

Quantity	Price (P) (Rs)	TR = (P*Q) (Rs)
1	100	100
2	90	180
3	80	240
4	70	280
5	60	300
6	50	300
7	40	280
8	30	240
9	20	180
10	10	100

As the full cost of the monopolist firm is zero, the income can be the maximum in which TR is the maximum. That is, on the sixth unit of output the firm might be maximizing its profit and the fast run equilibrium price might be Rs 50.

income of the firm = three hundred

quick run equilibrium charge = Rs 50

profit = TR - TC

= 300 - 0

income = Rs 300

If the whole price is Rs one thousand , then the equilibrium may be at a point in which the distinction among TR and TC is the most.

TR is the maximum on the 6 th level of output.

So earnings = 300 – 1000 = - seven-hundred

So, the company is earning losses and now not earnings. as the monopolist company is incurring losses inside the short run, it'll stop its production in the long run.

If the monopolist firm of Exercise 3 was a public sector firm. The government set a rule for its manager to accept the government fixed price as given (i.e. to be a price taker and therefore behave as a firm in a perfectly competitive market). And the government has decided to set the price so that demand and supply in the market are equal. What would be the equilibrium price, quantity and profit in this case?
