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.
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.
Paul Marlor Sweezy (April 10, 1910 – February 27, 2004) was a Marxist economist, political activist, publisher, and founding editor of the long-running magazine Monthly Review. He is best remembered for his contributions to economic theory as one of the leading Marxian economists of the second half of the 20th century.
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.
In order to distinguish themselves well, these firms can compete in price, but more often, oligopolistic firms engage in non-price competition because of their kinked demand curve. In the kinked demand curve model, the firm will maximize its profits at Q,P where the marginal revenue (MR) is equal to the marginal cost (MC) of the firm.
MATLAB allows matrix manipulations, plotting of functions and data, implementation of algorithms, creation of user interfaces, and interfacing with programs written in other languages. Although MATLAB is intended primarily for numeric computing, an optional toolbox uses the MuPAD symbolic engine allowing access to symbolic computing abilities.
Second, spending on the sales effort was an important outlet for surplus as large firms engaged in non-price forms of competition and sought to enlarge demand. However, such marketing expenditures (advertising, sales promotion, excessive model changes, etc.) do not provide any additional use-value and therefore may be treated as waste.
Cournot's curve of 'demand or sales' Cournot was wary of psychological notions of demand, defining it simply as the amount sold of a particular good (helped along by the fact that the French word débit, meaning 'sales quantity', has the same initial letter as demande, meaning 'demand' [7]). He formalised it mathematically as follows:
