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.
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 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 four-sides model (also known as communication square or four-ears model) is a communication model postulated in 1981 by German psychologist Friedemann Schulz von Thun. According to this model every message has four facets though not the same emphasis might be put on each.
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.
Shannon–Weaver model of communication [86] The Shannon–Weaver model is another early and influential model of communication. [10] [32] [87] It is a linear transmission model that was published in 1948 and describes communication as the interaction of five basic components: a source, a transmitter, a channel, a receiver, and a destination.
Explicit or implicit communication – any communication between the participant and experimenter, whether it be verbal or non-verbal, that may influence their perception of the experiment. Weber and Cook have described some demand characteristics as involving the participant taking on a role in the experiment. These roles include:
