In this essay I would discuss the price and output determination under the one essential type of imperfect competition markets- oligopoly.
Inter-firm interactions in imperfect markets take many forms. Oligopoly theory, those name refers to competition among the few, lack unambiguous results of these interactions unlike monopoly and perfect competition. There is a variety of results derived from many different behavioural assumptions, with each specific model potentially relevant to certain real-world situations, but not to others.
Here we are interested in the strategic nature of competition between firms. Strategic means the dependence of each person s proper choice of action on what he expects the other to do. A strategic move of a person influences the other person s choice, the other person s expectation of how would this particular person behave, in order to produce the favourable outcome for him. 2.
