Problem 3. Analyze the general equilibrium effects of an increase in taxes. Illustrate your answer with a graph. Organize your answer by discussing (1) Does the change shift the IS curve and/or the LM curve? (2) How does the change affect the equilibrium interest rate and output? (3) Describe the effect of the change with your own words by focusing on the changes in the composition of GDP. Does the change shift the IS curve and/or the LM curve? How does the change affect the equilibrium interest rate and output? Describe the effect of the change with your own words by focusing on the changes in the composition of GDP.

37. If the equilibrium level of GDP is $30,000, using the equations for C, I, G, and NX shown above, find the value of the marginal propensity to consume. C=4,000+ 0.5Y I= 1,500 G=2,250 NX=-150
Stiller 1. Suppose an economy is represented by the following equations. Consumption function C = 100 + 0.8Yd Planned investment I = 38 Government spending G = 75 Exports EX = 25 Imports IM= 0.05Yd Autonomous Taxes T = 40 Planned aggregate expenditure AE = C + I + G + (EX - IM) a. By using the above information calculate the equilibrium level of income for this economy, b. Calculate the value of expenditure multiplier. c. Suppose that government spending is increased by 5, what will happen to the equilibrium income level?
4. What do we mean when we talk about the export base of a region? How does an increase in the export base affect total employment? How does this relate to the multiplier? What factors limit the size of the multiplier within cities?
if the government cuts taxes in period 1 and cuts government spending in period 2 - this will increase the disposable income of the consumers - won't this increase consumption for consumers having an ambiguous effect on private saving. this is because if consumption is a normal good - increasing the income - positive income effect. My question is for some reason if consumer' disposable income increases - doesnn't this mean consumption must increase - whether it increases more/ enough to neutralise the tax cut effect is debatable and situation dependent - but surely there is an ambiguous effect on private saving for this reason

Suppose an economy had aggregate demand components with the following relationships: Consumption spending, C=140+.60*(DY) Investment spending,I=25+.15*Y Government Spending, G= 0 Net Export Spending,X=0 Tax collections, Tx=0 a. What is the equilibrium income for this economy? b. If the government decided to increase G spending by 6, what would be the new equilibrium income for this economy? c. If instead the government decided to reduce Tx (taxes) by 10, what would be the new equilibrium income for the economy? d. If instead the government decided to increase G spending and Increase Tx (taxes) by 20, what would be the new equilibrium for this economy?

Answer all four questions based on the following diagram. 1. Calculate the MPC in the above diagram. 2. Based on Diagram 1, If private Investment of $100 is added to the existing C, calculate the new equilibrium level of NI. 3. Given your answer to the previous question (question #2) calculate by how much G should change, if the full employment level in the economy is at $3000. 4. Based on the answer to the previous question (question #3), if half of those government expenditures are financed through lump sum taxes, calculate the new level if NI? (C+I+G)
2. The consumption function Consider a country with the national income of $12 billion, the amount of taxes paid by households of $3 billion, and household consumption of $7 billion. Suppose that the marginal propensity to consume (MPC) is 0.75. On the following graph, use the blue line (circle symbol) to plot the economy's consumption function. Hint: You should plot the first point where household consumption equals $7 billion. Then, plot the second point when real disposable income rises by $4 billion. REAL CONSUMPTION (Billions of dollars) 20 18 16 + 14 12 10 0 0 2 4 6 8 10 12 14 16 18 20 REAL DISPOSABLE INCOME (Billions of dollars) -0 O $7.75 billion O $9.75 billion O $7.5 billion O $10.75 billion Consumption Function (?) Suppose now that country's national income increases to $13 billion. Assuming the amount paid in taxes is fixed at $3 billion and MPC= 0.75, what will be the new household consumption?
