We know, an oligopolistic firm faces a demand curve with the kink at the equilibrium price level. When an oligopoly increases the price above the equilibrium level, the competitors maintain their prices. Hence, the consumers buy the product from the competitors at a lower price.

Why does oligopoly have kinked-demand curve?

The oligopolist faces a kinked‐demand curve because of competition from other oligopolists in the market. If the oligopolist increases its price above the equilibrium price P, it is assumed that the other oligopolists in the market will not follow with price increases of their own.

What is the Sweezy model?

The Sweezy model, or the kinked demand model, shows that price stability can exist without collusion in an oligopoly. Two firms “squabble” over a market. On the other hand, whenever the price of one firm fell, its rival would reduce its own price too to maintain its market share.

Where does the kink in the demand curve occur What happens to the marginal revenue curve?

What happens to the marginal revenue curve? (5 points) The kink in the demand occurs at the horizontal level of the original market price because anything below that will be steeper and anything above that will be flatter.

What is the implication of a kinked demand curve?

The implication here is that because of the threshold effect, a price rise will induce a more elastic response than a price cut and the demand curve will be kinked at the existing price. The main idea of this section is that the individual kinked demand curves are likely to have an impact on market demand.

What is the collusion model?

In the simplest form of collusion, overt collusion, firms openly agree on price, output, and other decisions aimed at achieving monopoly profits. Firms that coordinate their activities through overt collusion and by forming collusive coordinating mechanisms make up a cartel. Firms form a cartel to gain monopoly power.

What does a kinked demand curve show?

A kinked demand curve occurs when the demand curve is not a straight line but has a different elasticity for higher and lower prices. This model of oligopoly suggests that prices are rigid and that firms will face different effects for both increasing price or decreasing price. …

Where did the kinked demand curve theory come from?

1. Introduction The kinked demand curve theory of oligopoly has a distinguished lineage. Put forward independently by Hall and Hitch (1939) and Sweezy (1939), this theory sought to explain the rigidity of prices under oligopoly.

How is the kinked demand theory of oligopoly determined?

Kinked-Demand Theory of Oligopoly. The market demand curve that each oligopolist faces is determined by the output and price decisions of the other firms in the oligopoly; this is the major contribution of the kinked‐demand theory. The kinked‐demand theory, however, is considered an incomplete theory of oligopoly for several reasons.

Why is the kink at the prevailing price level?

The kink is formed at the prevailing price level because the segment of the demand curve above the prevailing price level is highly elastic and the segment of the demand curve below the prevailing price level is inelastic. A kinked demand curve dD with a kink at point K has been shown in Fig. 29.4.

What happens when demand is kinked in a price war?

Because there is a ‘price war’ demand for a firm is price inelastic – there is a smaller percentage rise in demand. If demand is inelastic and price falls, then revenue will fall. If the kinked demand curve is true, the firm has no incentive to raise price or to cut price.
