AGGREGATE SUPPLY SHIFTS: Changes in the aggregate supply determinants can shift either the short-run aggregate supply curve and the long-run aggregate supply curve. The mechanism is comparable to that for market supply determinants and market supply. We have two options -- an increase in aggregate supply and a decrease in aggregate supply. An increase in resource quantity or quality or a decrease in resource prices shift the aggregate supply curves to right. A decrease in resource quantity or quality or an increase in resource prices shift the aggregate supply curves to left.

KINKED-DEMAND CURVE ANALYSIS An analysis using the kinked-demand curve to explain rigid prices often found with oligopoly. The kinked-demand curve contains two distinct segments--one for higher prices that is more elastic and one for lower prices that is less elastic. Key to this analysis is that the corresponding marginal revenue curve contains three segments--one associated with the more elastic segment, one associated with the less elastic segment, and one associated with the kink. A profit-maximizing firm can then equate marginal cost to a wide range of marginal revenue values along the vertical segment of the marginal revenue curve. This suggests that marginal cost must change significantly before an oligopolistic firm is inclined to change price.
