Oligopoly Flashcards
(10 cards)
The distinguishing features of an oligopoly are that:
Natural or legal barriers prevent the entry of new firms
A small number of firms compete
Oligopoly markets share some characteristics of other market structures:
Oligopoly is similar to a monopoly in that each firm has market power to determine its own price
Oligopoly might be similar to monopolistic competition in that each firm makes a differentiated product, but this is not a necessary condition of monopoly
The quantity sold by one firm in an oligopoly depends on
Each firms own price and the prices and quantities sold by all other firms
The linked demand curve model of oligopoly is
based on the assumption that each firm believes that if it raises its price, others will not follow but that if it cuts its own price, so will other firms
The demand curve that an oligopoly firm believes it faces has a kink at the current
Price and quantity
Above the link demand is
Elastic because all other firms prices remain unchanged
Below the kink demand is is
inelastic because all other firms prices change in the line with the price of the firm shown in the figure
The kink in the demand curve means that
MR curve is discontinuous at the current quantity
Fluctuations in MC that remain within the discontinuous portion of the MR curve leave the profit maximising quantity and price..
Unchanged
If MC increases enough, all firms
Raise their prices and the kink vanishes
