A post-Keynesian theory of aggregate demand emphasizes the role of debt, which it considers a fundamental component of aggregate demand; [7] the contribution of change in debt to aggregate demand is referred to by some as the credit impulse. [8] Aggregate demand is spending, be it on consumption, investment, or other categories. Spending is ...
The aggregate consumer demand curve is the summation of the individual consumer demand curves. The aggregation process preserves only two characteristics of individual consumer preference theory—continuity and homogeneity. Aggregation introduces three additional non-price determinants of demand: Number of consumers

The demand for gross domestic product is measured by the aggregate demand function which is: AD = C + I + G + (X-M) Aggregate demand is the sum of all individual demands in the market. [6] Having said that, aggregate behavior may or may not result in changes of the aggregate demand due to the different thoughts of economics.
Keynes interprets this as the demand for investment and denotes the sum of demands for consumption and investment as "aggregate demand", plotted as a separate curve. Aggregate demand must equal total income, so equilibrium income must be determined by the point where the aggregate demand curve crosses the 45° line. [63]
The dynamic aggregate demand curve shifts when either fiscal policy or monetary policy is changed or any other kinds of shocks to aggregate demand occur. [5]: 411 Changes in the level of potential Y also shifts the AD curve, so that this type of shocks has an effect on both the supply and the demand side of the model. [5]: 412
The aggregate demand of society is, in general, a function of the price system and the entire distribution of incomes: (,, ...
If the demand decreases, then the opposite happens: a shift of the curve to the left. If the demand starts at D 2, and decreases to D 1, the equilibrium price will decrease, and the equilibrium quantity will also decrease. The quantity supplied at each price is the same as before the demand shift, reflecting the fact that the supply curve has ...
