List the three different ways in which oligopoly firms may have.
Oligopoly firms may behave in the following three ways:
1) Cartel - In order to avoid undue competition, oligopolistic firms may engage in formal agreements or contracts. This will not only allow them to maximise their total profits together, but also capture a significant market portion.
2) Informal understanding - Each firm may decide on its own, how much units of output are to be produced for maximising its individual profit, assuming that other firms would not change their strategies and decisions regarding the units of output to be produced.
3) Advertisement and differentiated product - It may happen that the firms realise that price competition will leave them nowhere and consequently they emphasise more on advertising their products. It will enable them to capture the minds of consumers and indirectly increase their market portion.
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.
Comment on the shape of MR curve in case when TR curve is a
(a) Positively sloped straight line
(b) Horizontal straight line
A monopoly firm has a total fixed cost of Rs 100 and has the following demand schedule:

Marginal Revenue |

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.
From the schedule provided below calculate the total revenue, demand curve and the price elasticity of demand:

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?
What is meant by prices being rigid? How can oligopoly behavior lead to such an outcome?
Explain why the demand curve facing a firm under monopolistic competition is negatively sloped.

Explain through a diagram the effect of a rightward shift of both the demand and supply curves on equilibrium price and quantity.
How does an increase in the price of an input affect the supply curve of a firm?
What does the price elasticity of supply mean? How do we measure it?
Why is the total revenue curve of a price-taking firm an upward-sloping straight line? Why does the curve pass through the origin?
Will a profit-maximising firm in a competitive market ever produce a positive level of output in the range where the marginal cost is falling? Give an explanation.
