Use the information given to calculate the following:
(a) The MIR and MC schedules
(b) The quantities for which MIR and MC are equal
(c) The equilibrium quantity of output and the equilibrium price of the commodity
(d) The total revenue, total cost and total profit in the equilibrium

(b)MR equals MC at the 6th unit of output i.e., 4.
(c) At equilibrium, MR equals MC, and right here MR equals MC on the sixth unit of output, wherein MC is upward sloping. Hence, the equilibrium price is Rs 19.
(d) TR = Rs 114
TC =Rs 109
general earnings = TR - TC
= Rs 114 – 109 = Rs five
Hence, income is the same as Rs 5 .
List the three different ways in which oligopoly firms may have.

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.
If duo poly behavior is one that is described by Cornet, the market demand curve is given by the equation q = 200 - 4p and both the firms have zero costs, find the quantity supplied by each firm in equilibrium and the equilibrium market price.
Comment on the shape of MR curve in case when TR curve is a
(a) Positively sloped straight line
(b) Horizontal straight line

What would be the shape of the demand curve so that the total revenue curve is?
(a) A positively sloped straight line passing through the origin?
(b) A horizontal line?
What is meant by prices being rigid? How can oligopoly behavior lead to such an outcome?
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?
Explain why the demand curve facing a firm under monopolistic competition is negatively sloped.

Ii. Below the equilibrium price
How does an increase in the number of firms in a market affect the market supply curve?
When does a production function satisfy decreasing returns to scale?
The following table gives the total product schedule of labour. Find the corresponding average product and marginal product schedules of labour.
A firm earns a revenue of Rs 50 when the market price of a good is Rs 10. The market price increases to Rs 15 and the firm now earns a revenue of Rs 150. What is the price elasticity of the firm’s supply curve?
In what respect do the supply and demand curves in the labor market differ from those in the goods market?
