Thus this demand curve is described as perfectly elastic. A perfectly elastic demand is a demand that has an elasticity coefficient of infinity. Accordingly, a demand curve must describe some particular time period. Over a very short period of time—say a day—the demand for a good may not react immediately. Thus a demand curve that covers a long period will be more elastic than one for a short period.. FIGURE 8.6 Perfectly Elastic Demand.

The kinked demand curve describes price rigidity. According to the kinked-demand curve model, each firm faces a demand curve that is kinked at the currently prevailing price. This implies a demand curve that is more inelastic for price decreases than for price increases. This kink in the demand curve implies a discontinuity in the marginal revenue curve, so only large changes in marginal cost lead to changes in price.
