代写作文：利率对人们的影响
由于利率下调，12月份的零售销售疲软。随着澳洲政府降低利率，人们投资意愿越来越强。此外，他们不打算购买或消费零售产品。人们的支出很大程度上受到利率的影响。此外，总开支模型在计算零售销售额方面也很有用。总支出模式基本上是消费、投资、政府采购和净出口的总和。这四个重要因素所占比例最大。
消费函数:C = Co + MPC (Yd)
C =总消耗量
Co =自主消费，其数量与处置收入无关
边际消费倾向。这主要是0和1之间的一小部分，MPC相当于处置收入的改变所带来的消费变化(Gilman, 2006)。
MPC = C变化量/ Yd变化量
处置收入
与MPC相同的概念是MPS:边际储蓄倾向。它相当于处置收入的变动所带来的储蓄
MPC = C变化量/ Yd变化量
由于整个收入不是消费就是储蓄，因此收入的任何变动也应该消费或储蓄。因此:MPC + MPS = 1
代写作文：利率对人们的影响
The retail sales in December are weak because of the interest rate reduced. As the government of Australia reduced the interest rate the people intend to invest more and more. Moreover, they do not intent to buy or expend on the retail products. The expenditure of the people is immensely influenced by the interest rate. Moreover, the aggregate expenditure model is useful in the matter it helps in calculating the retail sales. The aggregate expenditure model is basically the total of the consumption, investment, government procurement along with net export. These important four factors display the biggest share.
The consumption function: C = Co + MPC (Yd)
C = Total consumption
Co = autonomous consumption, which amount is independent of the disposal revenues
MPC = marginal tendency of consuming. This is mainly a fraction between the 0 and 1 as well as MPC is equivalent to alter in consumption brought about by a alteration of the disposal income (Gilman, 2006).
MPC = Change in C/ Change in Yd
Yd = Disposal income
A same conception as MPC is MPS: The marginal propensity to save. It is equivalent to the alteration is saving (S) brought about by the alteration in the disposal revenues
MPC = Change in C/ Change in Yd
Since the entire income should be either consumed or saved, thus any modification in income should also be consumed or else saved. Hence: MPC + MPS = 1
