consider the macroeconomic model shown below:

Because government spending is determined by a political process and is not dependent on fundamental economic variables, we will focus in this lesson on an explanation of the determinants of consumption and investment. Why the AD line is upward sloping?Suppose the government spending falls by 100 and in this case marginal propensity to consumeis 0.8. what is the value of change in output. (Mark all that apply.) An investment of P400,000 will, A:A rate of return refers to the net gain or the loss of an investment over a certain time period, Q:In monopolistically competitive industries, Per capita, A:Since you have asked multiple questions, we will solve one question at a time. Q:You are the Minister of Trade for a small island country with the following annual PPC: However, the similarities between, for example, all the classical models are great enough to warrant the expression the classical model. $1,000b. Real GDP Suppose that the real inter, Suppose a closed economy has an aggregate consumption function given by C = 100 + 0.50Yd and generates $2600 output and income in equilibrium. Solve for the equilibrium level of output in the following two scenarios: Infant Deaths per 1,000 Live Births Consider the following macroeconomic model:C=C +(Y T)T=T +tYI=I RG=GX=X YL=Y RM=MIn this model,Yis national income,Cis consumption,Tis taxes,Iis investment,Risthe interest rate,Gis government expenditure,Xare net exports,Lis money demand,andMis money supply. Consider the macroeconomic model shown below: C = 500+ 0.80Y | = 1,500 G = 1,000 NX = - 100 Y=C+I+G+ NX Consumption function Planned investment function Government spending function Net export function Equilibrium condition Fill in the following table. To understand such models, you must first understand the models where this complication does not arise.

The market's, Q:The closer a market's Herfindahl - Hirschman Index (HHI) is to If planned investment falls by 100, how much does the equilibrium level of output fall? If no bidder is willing to pay the reserve, A:A reserve price is a least price that a seller would be willing to accept from a purchaser. Consumption Investment is such an important part of our economy because it affects both short-run aggregate demand and long-run economic growth. $1,000 (Government purchases remain at 350.). a) What is the equilibrium level of Y? Many different economic variables influence the consumption decisions Podunkians make. Since interest rates with different maturities are highly correlated, they typically move in the same direction and the direction of a variable is typically what we are interested in. Write down the IS function. Q:How has olive oil impacted the economy? Two of the variables are stock variables: K and M. Prices cannot be characterized as a stock or flow variable. If the real interest rate at the bank is 6%, you would not buy the machines. s= saving rate $1 ,500 $|: $ $2,250 $l: $, Explore over 16 million step-by-step answers from our library. Including different interest rates with different maturities would complicate the models but it would not buy you very much. 15.00 Also, show the value for the AE line at the vertical in, Consider an economy that is described by the following equations: C = 140 + 0.80(Y - T) - 200r Consumption Function T = 400 + 0.1Y Tax Function I = 1000 - 700r Investment Function L = 0.5Y - 1000i, Given: C=150 + 0.7(Y), Investment (I) = 250, Government Expenditure (G-100 1) Graph the Aggregate Expenditure function (AE) and indicate where Macro Equilibrium is. Were the solution steps not detailed enough? Compute for the effective annualinterest rate if nominal rate is 7%compounded continuously.. $1,000. We will assume that the money multiplier is constant and since the monetary base is completely under the control of the central bank, the central bank will control the money supply. 0 u(W)=W. $1,000 If the expected rate of return in greater than the real interest rate, the investment makes sense. In short, the neo-classical synthesis claims that the Keynesian model is correct in the short term while the classical model is correct in the long run. But because of the nature of investment, it has a long-term impact on the economy as well. For the below ME alternatives, which machine should be selected based on the AW analysis., A:When more than two alternatives are offered for a project and their lifespans differ, the annual, Q:Kelsey purchases a retirement annuity that will pay her $1,500 at the end of every six What is the marginal propensity to consume foreign goods? &= 385 - 770\\ Given the above variables, calculate the equilibrium level of output. Graph planned expenditure as a function of income.b. (Enter your responses as integers.) a What is the multiplier? | = 1,500 440 This assumption will be true if the workforce is constant and individuals in the labor force either work full time or not at all. (I) Investment = $50 billion. $1,500 Government purcha, Assume the consumption function is C = 200 + 0.75(Y - T), I = 100; G = 100; T =100. The MPC and MPS are therefore: Since the Consumption Function and the Savings Function are both straight lines in this example, and since the slope of a straight line is constant between any two points on the line, it will be easy for you to verify that the MPC and the MPS are the same between any two points on the line. 1 answer below . Q:Perform these same calculations for 2021 and 2022, and enter the results in the following table., A:Price index measures the cost of market basket of goods and services, Q:Question a. Graph planned expenditure as a function of income.b. For example, L is still the observed amount of work (a variable) while LS and LD represent the supply of labour and the demand for labour. As disposable income goes up, consumption goes up and this is shown by movement along a single consumption function. Remember from our lesson on National Income Accounting that investment only occurs when real capital is created. To simplify our discussion, we will assume that Consumption is a linear function of Disposable Income, just as it was graphically shown above. If the consumption function is C = 100 + 0.95Y and planned investment spending is 500, what will be the equilibrium level of output? What is the Government Spending Func, In Macroland, autonomous consumption equals 100, the marginal propensity to consume equals 0.75, net taxes are fixed at 40, planned investment is fixed at 50, government purchases are fixed at 150, and net exports are fixed at 20. Government spending: G = 60. B. In other words, what would your consumption be if your disposable income were zero? The bond, Q:Home prices in a particular neighborhood average $350k with a standard deviation of $30k. Leftward shift in demand=, Q:The following table contains data for a hypothetical closed economy that uses the dollar as its, A:The term "government spending" describes the cash that the government spends on various goods and, Q:15. $1,500 0.4 c. 0.6 d. 0.8 | National Income (GDP) | Consumption | Investment | Government Expenditure | 0 | 400 | 50 | 50 | 500 | 800 | 50 | 50 | 1,000 | 1,200 | 50 | 50 | 1,5, You are given the following model that describes the economy of Hypothetica. bi This problem has been solved!

The marginal propensity to consume (MPC) is the slope of the: a. GDP curve. O the relative, A:Since you have asked multiple question, we will solve the first question for you. F Note that there are actually many minor variations of the neoclassical synthesis. Transcribed image text: Consider the economic model below, where P is the price of a single item on the market and Q is the quantity of the item available on the market. (b) Total wealth. Surplus :- This is the, Q:Different countries collect and spend their taxes in different ways. Transcribed Image Text: Consider the macroeconomic model shown below: C = 1,500+ 0.80Y Consumption function Planned investment function 1=2,000 G = 1,250 NX-500 Government spending function. It represents the expected increase in Consumption that results from a one unit increase in Disposable Income. So far, each variable has represented an observed quantity. Consider the table below, where each row illustrates a macroeconomic relationship between consumption, savings and disposable income (note that C = Consumption, S = Savings, and DI = Disposable Income, Aggregate expenditure equals the sum of consumption, investment, government spending, and net exports. consumption: C = a+b (1-t)Y (a > 0, 0. investment: I = e-`R (e > 0, ` > 0) Money Market. What is the consumption function? In economics we call this dissavings. Point E is called the breakeven point because it is the point where there are no savings but there are also no dissavings. $1,500 Inflation rate =5% per year When initial investment or investment amount is not given in question, we calculate, Q:The following table shows a money demand schedule, which is the quantity of money demanded at, A:The need for liquid assets is reflected in the demand for money. $8,600 The dollars spent on the investment have the immediate impact of increasing spending in the current time period. Aggregate c. autonomous consumption curve. However, we have not made any distinction between the demand and the supply of labor which we need to do from now on. No one knows exactly how the macroeconomic variables are related. a. occurs at the point where the consumption function crosses the 45-degree line. Suppose Y = $200, C = $160, S = $40, and I = $40. (Enter your responses as integers.) Government spending (G) b. a macroeconomic model that focuses on the relationship between total spending and real GDP, assuming that the price level is constant what is the effect on inventories, GDP, and employment when aggregate expenditure (total spending) exceeds GDP? Can there be consumption without income? Net exports 50 View this solution and millions of others when you join today! Should you borrow the money and buy the new equipment? assume that government spending decreases from Also calculate the MPC and the MPS in this example. The Consumption function is C = 600 + 0.75(Y - T) - 30(r). The central bank actually has othermonetary policy instrument apart from being able to determine the money supply. Question options: 2 Unfortunately, not all of these models consistent - one model may predict that unemployment will fall if the central bank lowers the target interest rate while another may claim that such a change will not affect unemployment. 105 Investment c. Consumption d. Net exports e. Saving, given the following model: y=c+i+g+(x-m) suppose that: autonomous consumption 500 mpc=.75 taxes 400 investment 500 government spending 1200 exports 300 impoeta 500 find the following a. equi, In the Keynesian cross, assume that the consumption function is given by C = 200 + 0.75(Y - T). Lets do an example using data for a hypothetical economy. there isan income tax t=0.1, Y=C+I+G+NX Income Identity C=90+0.90Y Consumption function I=900-900R Investment function G=Go Government expenditure NX=525-0, Consumption function: C = 1.5 + 0.75(Y - T) trade balance function: TB = 5(1 - 1/E) - 0.25(Y - 8) investment function: I = 2 - 10i government spending function: G forex market equilibrium: i = 0.1 + (1-E)/E Write an equation that characterizes the I, In the Keynesian cross, assume that the consumption function is given by C = 200 + 0.75(Y - T). If you look up the IS-LM model in different text books you will probably see different models but the main predictions from the models do tend to be the same. Lets look at several of these non-income determinants of consumption and savings: You can likely think of other factors that are unrelated to income that could shift the Consumption and Savings Functions.
