Question 1 Explain fully how the equilibrium output, income, and employment are determined in the Keynesian model. Illustrate with an appropriate graph. Suppose that the equilibrium GDP is $500 billion and the full employment GDP is $600 billion. If the slope of the AE curve is 0.8, how much would the government have to change its expenditure to get the economy to full employment equilibrium? Illustrate your answer with an appropriate graph, and show the numerical values in your graph. Explain your understanding of the multiplier process used in answering part B.

Assume the following model of the expenditure sector: S=C+I+G+Nx TR=100 C=420+(4/5)YD I=160 G=180 Nx=-40 YD=Y+TR-TA TA=(1/6)Y If the government would like to increase the equilibrium level of output (Y) to the full employment level Y*=2,700, by how much should government purchases (G) be changed?
10 . In the “complete Keynesian model”, the investment functions was I = I0 - f(i). An analyst now proposes the following investment function: I = I0 - f(i) + qY, where “q” is a parameter and Y is national income = GDP. Provide two different arguments, i.e. explanations as to why this investment function makes sense. The focus is on the new term, qY (q times Y), in the function.

Suppose total expenditures are greater than total output: that is, E > Y. Draw a diagram illustrating this situation. According to Keynesian theory, what is likely to happen? Will the adjustment necessarily restore full employment?
The Aggregate Expenditure Model is traditionally called the” Keynesian Cross”. Use the Aggregate Expenditure Keynesian Cross diagram to show what happens to the economy under the following conditions: (Note that is different from the AS-AD Model.) What happens in the model if government expenditures are increased (G↑)? What happens if taxes are raised (T↑)? What happens to the US economy if the rest of the world experiences economic growth and imports more US goods (X↑)?
Consider the graphical representation of the Keynesian cross for a hypothetical country, where the planned aggregate spending line is graphed against the 45° line. Suppose that, in this country, there is an autonomous increase in aggregate spending of $20 billion. Show this change on the graph.

If the number is negative, be sure to include a negative sign.
To graphically represent this, you can create a simple Keynesian cross diagram. On the vertical axis, plot the national income (Y), and on the horizontal axis, plot the aggregate expenditure (C + I + G). The equilibrium point will be where the aggregate expenditure line intersects the 45-degree line representing national income. add explanation
Assume the Potential GDP is $15 trillion dollars. Use the table below to answer the following questions. Assume all values represent trillions of dollars. Use the table to create two graphs: 1. aggregate expenditure model and 2. an aggregate supply aggregate demand model. Note that the equilibrium in the table above will determine your real GDP and your potential GDP should be plotted in both graphs. What type of macroeconomic equilibrium does this economy reflect? Note that the multiplier is 2 because this economy has imports. If Investment expenditures increase by $2.5, how much does GDP increase? Does the increase in investment expenditures from part C result in a full employment equilibrium? Why? Graphically show the effects from part C in our Aggregate Expenditure Model and Aggregate Supply-Aggregate Demand Model.
Use the Keynesian cross model to predict the impact of an increase in government purchases on equilibrium GDP. State the direction of the change and give a formula for the size of the impact. An increase in taxes shifts the planned expenditure function downward. The change in income is given by AY= ΔΥ= -MPC 1-MPC An increase taxes shifts the planned expenditure function upward. The change in income is given by -MPC 1-MPC AY= XAT An increase in taxes shifts the planned expenditure function inward. The change in income is given by AY= 1 1-MPC XAT 1 1-MPC The direction of the shift is undetermined without knowing the slope of the PE function. The change in income is given by XAT XAT
