Consider the Aggregate expenditure model. Where:AD = C + I + G + NX (1)where I, G, and NX are all autonomous.C = C + c∗(Y + T R − T A)(2)where T A = tY with t ∈ [0, 1] is the proportional tax rate and c∗ ∈ (0, 1) is themarginal propensity to consume.a. Using the information above, solve for AD. Combineall the autonomous terms into one term, A. b. In an (x, y) plane, where Y is on the horizontal axis and AD is on thevertical axis, illustrate the AD curve you derived above along with the 450line.Make sure to explain how you got the Y-intercept and solve for the slope c. Provide an economic interpretation for the slope of the AD function. d. Solve for the equilibrium level of output and show what happens to outputwhen G increases by 1 unit. That is, what is ∆Y ? Show your result graphicallyand explain how the AD curves shifts and by how much. Briefly explain.
Right click on image and click on open image in new tab to see the full and clear image. Consider two closed economies that are identical except for their marginal propensity to consume (MPC). Each economy is currently in equilibrium with real GDP and total expenditure equal to $100 billion, as shown by the black points on the following two graphs. Neither economy has taxes that change with income. The grey lines show the 45-degree line on each graph. The first economy's MPC is 0.5. Therefore, its initial total expenditure line has a slope of 0.5 and passes through the point (100, 100). The second economy's MPC is 0.75. Therefore, its initial total expenditure line has a slope of 0.75 and passes through the point (100, 100). Now, suppose there is a decrease of $20 billion in investment in each economy. Place a green line (triangle symbol) on each of the previous graphs to indicate the new total expenditure line for each economy. Then place a black point (plus symbol) on each graph…
Consider the following income/expenditure diagram in the simple Keynesian model. If taxes, T, were increased, then Group of answer choices A) The Y = C+S+T line would shift to the right, and equilibrium Y would increase. B) the C+I+G line would shift downward, and equilibrium Y would decrease. C) The Y = C+S+T line would shift to the left, and equilibrium Y would decrease. D) neither of the lines would shift, and equilibrium Y would stay the same. E) the C+I+G line would shift upward, and equilibrium Y would increase.
The total expenditure schedule in Macroland begins with these initial levels (in billions of dollars): Income = 1,000; Consumption = 900; Investment = 200; Government = 300; Net Exports = −100. If the MPC = 0.75 and income increases in increments of 200, find the equilibrium level of income. If full employment requires an income level of 2,000, what (if anything) should the government do? Indicate both the direction of the spending change and the size of the spending change.
The levels of real disposable income and aggregate expenditures for an economy are given in the following table. -- Use the blue points (circle symbol) to plot the expenditures line for this economy on the following graph. Line segments will automatically connect the points. The black line represents the 45-degree line, where aggregate expenditures equal real GDP. Use the black point (plus symbol) to indicate equilibrium real GDP. - - In the previous graph, if the economy produces at an output level that is higher than equilibrium GDP, then the economy is in because aggregate expenditures are real GDP, and unplanned inventory investment is Read GDP (Y) Aggregate Expenditures (AE) (Trillions of dollars per year) (Trillions of dollars per year) 0 1 1 1.75 2 2.5 3 3.25 4 4 5 4.75 6 5.5 7 6.25 8 7 Use the blue points (circle symbol) to plot the expenditures line for this economy on the following graph.

Below graph these are 5 questions. Where equilibrium will shift to A or to B if : There is a rise in public sector borrowing There is a rise in government government subsidies to the motor industry The government spends less on defence The basic rate of income tax is raised The VAT rate is cut from 20% to 15%.
In the Keynesian cross model, assume that the consumption function is given by C = 20 + 0.8(Y- T). Planned investment is 200; government purchases and taxes are both 400. There is no foreign trade. An economist has claimed that the full employment level of output is 2,400. How much should the government expenditure or taxes rise or fall to achieve full employment?
This question has four parts, here is the fourth and final part. 1.4. Create a graph for the aggregate expenditures (AE) model in Excel using the data from Table 1: A Private Closed Economy. (table 1 is in the attachment) tips: Remember, the 45degree line (also known as the Keynesian Cross) is a tool that shows how differences in aggregate expenditures and real GDP can affect business inventories which will affect future levels of real GDP. Aggregate expenditure and GDP are both function of consumption, investment, government spending, and net exports. So, the equations for the two are identical: Y = C + I + G + NX, and AE (aggregate expenditure) = C + I + G + NX For private closed economy the equation is: Y = C + I , and AE (aggregate expenditure) = C + I
In the following table, you are given the following parameters for the economy of Atris: C = 100 + 0.85Y I = 300 G = 150 X = 60 IM = 10 + 0.05Y a) What is the value of expenditures equilibrium? b) What is the value of total leakages and injections at expenditures equilibrium? c) Suppose autonomous expenditure increases by $25. What is the new value of expenditure equilibrium?
d. Now G assumes its original value of G = 800. Congress decreases the tax rate from (1/2) to (1/4). i) Use a model to sketch the effect of the decrease in the tax rate when the price level is held constant. ii) What is the new marginal propensity to consume? iii) Calculate the new equilibrium level of income.
At an intial point on the aggregate demand curve, the price level is 100, the real GDP is $18 trillion. After the price level rises to 110, however there is an upward movement along the aggregate demand curve, and real GDP declines to $14 trillion. If total planned spending declines by $200 billion in response to the increase in the price level, what is the MPC in this economy?
Consider a closed economy with no government, where aggregate demand is determined by autonomous consumption, investment (which is independent of output), and the marginal propensity to consume. a) Given that autonomous consumption is 20, investment is also 20, and the marginal propensity to consume is 0.6, write out an equation for aggregate demand (AD) in this economy. b) Given this aggregate demand equation, and the equilibrium equation Y = AD, use algebra to find the equilibrium level of Y. (2 marks) c) Draw a diagram with output (Y) on the x-axis and aggregate demand (AD) on the yaxis. Draw two lines on this diagram: (i) Y = AD, and (ii) the aggregate demand function from part (a). Label the intercept of the AD line, and the point where the two lines intersect, with numerical values. d) Suppose that the marginal propensity to consume falls from 0.6 to 0.5. What would the new equilibrium level of Y be? Illustrate your answer in the diagram you drew for part (c). e)…
