A kink in an otherwise linear demand curve. Note how marginal costs can fluctuate between MC1 and MC3 without the equilibrium quantity or price changing. The Kinked-Demand curve theory is an economic theory regarding oligopoly and monopolistic competition. Kinked demand was an initial attempt to explain sticky prices.
Sweezy did pioneering work in the fields of expectations and oligopoly in these years, introducing for the first time the concept of the kinked demand curve in the determination of oligopoly pricing. [3] Harvard published Sweezy's dissertation, Monopoly and Competition in the English Coal Trade, 1550–1850, in 1938.
The graph below depicts the kinked demand curve hypothesis which was proposed by Paul Sweezy who was an American economist. [29] It is important to note that this graph is a simplistic example of a kinked demand curve. Kinked Demand Curve. Oligopolistic firms are believed to operate within the confines of the kinked demand function.
The kinked demand curve for a joint profit-maximizing oligopoly industry can model the behaviors of oligopolists' pricing decisions other than that of the price leader. Above the kink, demand is relatively elastic because all other firms' prices remain unchanged.

The demand curve the oligopolist faces is that of two separate curves spliced together, creating a discontinuity in the MR curve. This means that a profit maximising firm will still produce at quantity Q and price P if marginal costs are equal to MC1, MC2 or MC3, thus explaining price stability.
The graph depicts a right-shift in demand from D 1 to D 2 along with the consequent increase in price and quantity required to reach a new market-clearing equilibrium point on the supply curve (S). The theory of supply and demand usually assumes that markets are perfectly competitive. This implies that there are many buyers and sellers in the ...
Price points A, B, and C, along a demand curve (where P is price and Q represents demand) In economics, a price point is a point along the demand curve at which demand for a given product is supposed to stay relatively high. The term "price point" is often used incorrectly to refer to a price. [1]
