SAVING LINE: A graphical depiction of the relation between household saving and household disposable income. The slope of this line is positive, greater than zero, less than one, and goes by the name marginal propensity to save. The vertical intercept of the saving line is autonomous saving. The saving and investment, or leakage and injection, analysis used in Keynesian economics begins with the saving line. Because consumption is the difference between disposable income and saving, the consumption line is a complementary relation to the saving line.

The production possibilities analysis has two main limitations:- First, Preferences: This analysis says nothing about which goods people want and which provide the most satisfaction. It only indicates the available options.

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.
