KINKED-DEMAND CURVE: A demand curve with two distinct segments with different elasticities that join to form a kink. The primary use of the kinked-demand curve is to explain price rigidity in oligopoly. The two segments are: (1) a relatively more elastic segment for price increases and (2) a relatively less elastic segment for price decreases. The relative elasticities of these two segments is directly based on the interdependent decision-making of oligopolistic firms.

It is measured by the intercept term of the investment line. The alternative to autonomous investment is induced investment, which does depend on income.
