The duopoly market have duopoly market characteristics which is alike characteristics of oligopoly market. So the characteristics of duopoly market are as follows: Duopoly market rigidity exists in this type of market structure.

It means price of product in this market does not change immediately with change in demand and supply in market.


In this type of market structure either advertising is done to increase its sales volume or by improving quality of its product. There is interdependency among firms as no firm can ignore the action and reaction of its rival firm.

Duopoly - Overview, Examples, and Types of Oligopolies

An iso-profit curve, for a give level of profit, is drawn on the basis of various combinations of prices charged by the rival firms. He assumed only two firms, A and B and their prices are measured along the horizontal and vertical axes, respectively.

Their iso-profit curves are drawn on the basis of the prices of the two firms. Iso-profit curves of the two firms are concave to their respective prices axis, duopoly market shown in Fig.

Iso- profit curves of firm A are convex to duopoly market price axis PA Fig.

For example, price combinations at points, a, b and c yield the same level of profit indicated by the iso-profit curve A1.

If firms B fixes its prices Pb1— firm A has two duopoly market prices, Pa1 and Pa2, to make the same level of profits.

When B reduces its price, A may either duopoly market its price or reduce it.

  • What it is:

A will duopoly market its price when he is at point c and raise its price when he is at point a. But there is a limit to which this price adjustment is possible.

This point is shown by point b. So there is a unique price for A to maximize its profits. This unique price lies at the lowest point of iso-profit curve. This is so duopoly market, iso-profit curve tends to shift rightward when A gains market from his rival B.

The reaction curves of A and B intersect at point E where their expectations materialize, duopoly market E is therefore equilibrium point. This equilibrium is stable. Fo, if any one of the firms duopoly market to this point, it will create a series of actions and reactions between the firms which will lead them back to point E.
