总支出被认为是整体消费的总和,投资政府采购和整体净出口与总支出的帮助乘数的概念解释,有助于反映总体乘数影响阻止他前面整体零售销售的变化。均衡GDP是产出的总量，其总产出将产生总支出o，足以购买产出的总量。如果经济生产的产品数量不同于关键的四个经济部门的总体数量，那么购买AE和总生产(Leeds, Von Allmen和Schiming, 2006)。凯恩斯确定并确定了自治支出的总体修正，它可以产生更大的国民收入修正。例如，在给定的案例研究中，家庭用品的消费下降了，零售额在一年的最后三个月增长了0.9%。另一方面，据观察，生产者自主投资的增加约为6000万美元，这将成为资源市场的收入，因此，在家庭销售下降约2.3%。家庭销售额随着家庭用品价格的下降而下降。他们的消费转化为生产者的收入，生产者将再次投资于市场，从而帮助创造额外的收入。该过程被认为是一个连续的过程，有助于创造乘数效应。如果乘数等于3.5，那么总开支将增加约6000万美元x 3.5 = 19.5
Aggregate expenditure is considered to be the sum of the overall consumption, investment government purchase and overall net export along with the help of the aggregate expenditure the concept of the multiplier is explained which help to reflect the overall multiplier impact on the stemming front he overall changes in the retail sales. Equilibrium GDP is the amount of the output whose overall production will generate the total spending o which will be sufficient to buy the amount of the output. If the economy produces the amount of product which differs to the overall amount across the key four sector of the economy buy AE and aggregate production (Leeds, Von Allmen and Schiming, 2006). The Keynes determined and identified the overall modification in autonomous expenditure which could generate the larger modification in the national incomes. For instance in the given case study the consumption of the household good is decreased where the retail value of the retail sale increase by 0.9 percent over the final three month of the year. On the other hand it is observed increase autonomous investment by the producer is around 60 m dollar it will become the income of the resource market and thus the decrease in the household sale is around 2.3 percent. Household sale decreases with the decreased prices of the household goods. Their spending is converted into the income of the producer who will again invest in the market and thus help to create extra income. The process is considered as the continuous process which helps to create the multiplier effect. If the multiplier is equal to 3.5 then the aggregate expenditure will increase by around $60 M x 3.5 = 19.5
M=1/MPS is basically utilized to determine the expenditure multiplier.
