\begin{aligned} \Delta \text { Inventories } &=G D P-A E \ &=\ 12,000 \text { billion }-\ 10,400 \text { billion } \ &=\ 1,600 \text { billion. } \end{aligned}
When GDP is equal to $\$ 4,000$billion, aggregate expenditure is equal to$\$5,600$ billion, so that the change in inventories is
\begin{aligned} \Delta \text { Inventories } &=G D P-A E \ &=\ 4,000 \text { billion }-\ 5,600 \text { billion } \ &=-\ 1,600 \text { billion. } \end{aligned}
Notice the negative sign in front of the $\$ 1,600$billion; if output is$\$4,000$ billion, then inventory stocks will shrink by $\$ 1,600$billion over the year. ## ECON2018 COURSE NOTES ： Here’s another way to see the logic behind Say’s law, with some simple equations. Because the loanable funds market clears, we know that the interest rate-the price in this market-will rise or fall until the quantity of funds supplied (savings,$S$) is equal to the quantity of funds demanded (planned investment plus the deficit, or$\left.I^{p}+(G-T)\right)$: Rearranging this equation by moving$T$to the left side, we have: Loanable funds market clears$\Longrightarrow \underbrace{S+T}{\text {Leakages }}=\underbrace{I^{p}+G}{\text {Injections }}$So now, we know that as long as the loanable funds market clears, leakages equal injections. Finally, remember that $$\text { Leakages }=\text { Injections } \Longrightarrow \text { Total spending }=\text { Total output }$$ # 宏观经济学原理作业代写Principles of Macroeconomics代考 0 如果你也在 怎样代写宏观经济学原理Principles of Macroeconomics学科遇到相关的难题，请随时右上角联系我们的24/7代写客服。 英国论文代写Viking Essay提供最专业的一站式学术写作服务：Essay代写，Dissertation代写，Assignment代写，Paper代写，网课代修，Exam代考等等。英国论文代写Viking Essay专注为留学生提供Essay代写服务，拥有各个专业的博硕教师团队帮您代写，免费修改及辅导，保证成果完成的效率和质量。同时提供查重检查，使用Turnitin高级账户查重，检测论文不会留痕，写好后检测修改，放心可靠，经得起任何考验！ 如需网课帮助，也欢迎选择英国论文代写Viking Essay！与其为国内外上课时差困扰，为国内IP无法登录zoom网课发愁，还不如选择我们高质量的网课托管服务。英国论文代写Viking Essay长期致力于留学生网课服务，涵盖各个网络学科课程：金融学Finance，经济学Economics，数学Mathematics，会计Accounting，文学Literature，艺术Arts等等。除了网课全程托管外，英国论文代写Viking Essay也可接受单独网课任务。无论遇到了什么网课困难，都能帮你完美解决！ ## 代写宏观经济学原理作业代写Principles of Macroeconomicsles of Microeconomics 涵盖了大多数经济学入门课程的范围和顺序。该文本包括许多当前的例子，这些例子是以政治上公平的方式处理的。其结果是对经济学概念的理论和应用采取了一种平衡的方法。第二版进行了彻底的修订，以提高清晰度，更新数据和当前事件的影响，并纳入许多审查者和采用者的反馈。 宏观经济学原理包含几个不同的主题，列举如下： ### 国内生产总值、通货膨胀和失业率Gross Domestic Product, Inflation, and Unemployment代写 在宏观经济学中，我们研究一个经济体产生的总产出。经济学家使用国内生产总值（GDP），即一个国家境内一年内生产的所有最终产品和服务的货币价值，来衡量一个国家的总产出。宏观经济学倾向于使用实际国内生产总值，而不是名义国内生产总值来进行比较，因为实际国内生产总值消除了通货膨胀的影响。用现值美元（不考虑通货膨胀）而不是不变美元来衡量增长，可能会显示出经济增长或衰退的错误感觉。 ### 总需求和总供给Aggregate Demand and Aggregate Supplye代写 总需求是指人们想要购买的商品和服务的总量。它衡量人们想要购买的东西，而不是实际生产的东西。总需求是消费、投资、政府开支和净出口的总和。总供给是一个经济体在给定价格水平下生产的总产出。我们考虑短期和长期的总供给。 其他相关科目课程代写： • Aggregate Equilibrium and Economic Growth总量平衡和经济增长 • Money, Banking, and Monetary Poliy货币、银行和货币政策 • Fiscal Policy and the Relationship Between Inflation and Unemployment 财政政策与通货膨胀和失业之间的关系 ## 宏观经济学原理的相关 考虑一下微观经济学家和宏观经济学家是如何分析价格波动的。在微观经济学中，我们专注于供应和需求如何决定特定市场的价格。在宏观经济学中，我们关注的是所有市场的价格水平变化。微观经济学研究公司利润最大化，产出优化，消费者效用最大化和消费优化。宏观经济学研究经济增长、价格稳定和充分就业。 Consider how microeconomists and macroeconomists analyze price fluctuations. In microeconomics, we focus on how supply and demand determine prices in a given market. In macroeconomics, we focus on changes in the price level across all markets. Microeconomics studies firm profit maximization, output optimization, consumer utility maximization, and consumption optimization. Macroeconomics studies economic growth, price stability, and full employment. ## 宏观经济学原理的相关课后作业代写 Government statistics show a consumer price index of$15.2$for 1931 and 166 for 1999. Thus, the overall level of prices has risen by a factor of$10.9$(which equals$166 / 15.2\$ ). We can use these numbers to measure Ruth’s salary in 1999 dollars. The calculation is as follows:
\begin{aligned} \text { Salary in } 1999 \text { dollars } &=\text { Salary in } 1931 \text { dollars } \times \frac{\text { Price level in } 1999}{\text { Price level in } 1931} \ &=\ 80,000 \times \frac{166}{15.2} \ &=\ 873,684 . \end{aligned}
