Oligopoly Flashcards
Price leadership
When one firm has a dominant position and firms with lower market shares follow the price changes of the leaders
Collusion
Takes place when rival companies cooperate for their mutual benefit
Cartel
Association of businesses and countries that collude to influence production levels and thus the market price
Interdependence
Where the decisions made by a business arent made in isolation, it must consider the likely reaction of rival firms
Prisoners dillema
Problem in game theory that demonstrates why 2 people might not cooperate even if in their best interests
Kinked demand curve
Assumes that a business faces a dual demand curve for its product based on the likely reaction of other firms
Key characteristics of an oligopoly
-Best defined by the actual behaviour of firms
-A market dominated by a few large firms
-High market concentration ratio
-Products can be differentiated
-Interdependent strategic decisions by firms
Concentration ratio
A measure of the total output produced in an industry by a given number of firms in the industry.
Interdependence expained
Firms are likely to be aware of others actions as there is a small amount of firms so the decisions of one firm influences the decisions of other firms. So firms must take into account the likely reactions of their rivals to things like changes in price. This causes oligopolistic industries to be at high risk of collusion and uncertainty
