Comment on the shape of MR curve in case when TR curve is a
(a) Positively sloped straight line
(b) Horizontal straight line
(i) Based on the relationship between MR and TR it can be said that when TR curve is a positively sloped straight line, then MR curve is a horizontal line. MR and demand curve are the same, and the price (AR) remains constant for different output levels. This happens under perfect competition.
(ii) When TR curve is a horizontal straight line, then MR is zero. Therefore, MR curve is also a horizontal straight line and coincides with the output axis.
List the three different ways in which oligopoly firms may have.
Will the monopolist firm continue to produce in the short run if a loss is incurred at the best short run level of output?
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.
What is meant by prices being rigid? How can oligopoly behavior lead to such an outcome?
A monopoly firm has a total fixed cost of Rs 100 and has the following demand schedule:

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.

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?
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?
