Of the four components of aggregate demand, consumption expenditure C is the largest contributing to between 60% and 70% of total expenditure. For this reason, we often start our analysis with this particular component.
The consumer's surplus is highest at the largest number of units for which, even for the last unit, the maximum willingness to pay is not below the market price. The aggregate consumers' surplus is the sum of the consumer's surplus for all individual consumers.he maximum amount a consumer would be willing to pay for a given quantity of a good is the sum of the maximum price they would pay for the first unit, the (lower) maximum price they would be willing to pay for the second unit, etc. Typically these prices are decreasing; they are given by the individual demand curve.
