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.

LONG-RUN AGGREGATE SUPPLY CURVE A graphical representation of the long-run relation between real production and the price level, holding all ceteris paribus aggregate supply determinants constant. The long-run aggregate supply curve, abbreviated LRAS, is one of two curves that graphically capture the supply-side of the aggregate market. The other is the short-run aggregate supply curve. The demand-side of the aggregate market is occupied by the aggregate demand curve. The vertical long-run aggregate supply curve captures the independent relation between real production and the price level that exists in the long run.
