The Life-Cycle/Permanent Income Model of Consumption makes a different prediction from the Keynesian Model, about how Consumption reacts to an increase in current income. Which of the following is the best description of the difference? O In the Keynesian Model, consumers will increasktheir spending by the mpc times the increase in income. In the Life-Cycle/Permanent Income Model, consumers will not increase their spending by much unless they believe that the increase in their income is permanent. O In the Life-Cycle/Permanent Income Model, consumers will increase their spending by the mpc times the increase in income. In the Keynesian Model, consumers will only increase their spending if they believe that the increase in their income is temporary. O In the Keynesian Model, consumers will increase their spending by the mpc times the increase in income. In the Life-Cycle/Permanent Income Model, consumers will only increase their spending if they believe that the increase in their income…
. Suppose an economy is represented by the following equations.Consumption function C = 100 + 0.8YdPlanned investment I = 38Government spending G = 75Exports EX = 25Imports IM = 0.05YdAutonomous Taxes T = 40Planned aggregate expenditure AE = C + I + G + (EX - IM)a. By using the above information calculate the equilibrium level of income for thiseconomy. b. Calculate the value of expenditure multiplier. c. Suppose that government spending is increased by 5, what will happen to theequilibrium income level?

QUESTIONS GO WITH GRAPH 7. Given this diagram, what is the numerical value of the autonomous spending simple multiplier? 8. Given this diagram, if the total autonomous spending were to decrease from 25 to 15, what will b the resulting equilibrium level of income?
Assume in a simple economy that the level of saving is –500 whenaggregate output equals zero and that the marginal propensity tosave is 0.2. Derive the saving function and the consumption func-tion, and draw a graph showing these functions. At what level ofaggregate output does the consumption curve cross the 45° line?Explain your answer and show this on the graph.
Consider a simple economy in which investment is constant and equal to $100 billion. There is no government or foreign sector, and the price level is constant. Consumption is C= $40 billion - 0.75Y What is the value of the marginal propensity to consume? what is consumption at an output of $1,000 bllion? a. c. What is the equilibrium GDP in this model? d. What is the value of the multiplier? e. What happens to equilibrium GDP should investment demand fall to S80 billion?
Assume in country Y, the average marginal propensity to save is 0.2. When the aggregateincome is zero, consumers spend 50 to consume. Derive the saving function and consumptionfunction for this country. What happens to consumption when the propensity to savedecreases to 0.1? Explain your answer and show this on the graph.
In a keynesian model it is assumed that the consumption function is given by C= 2000 + 0.75 (Y-T) and the planned investment is 1,000 government purchases and taxes are both of those and formulate and draw a graph of planned expenditure as a function of income What is the equilibrium level in the part above If the government purchases increased by 1250 what is the equilibrium income With the aid of a algebra prove that a balanced budget multiplier is always equals to 1
suppose that the government increases taxes and government purhcases by equal amounts.what happens to the interest rate and investment in response to this balanced - budget change? does your answer depend on the marginal propensity to consume?
1. Suppose the households in a hypothetical economy has the following consumption function C= a + cYd. Where is the disposable income. The government in this economy imposes a tax rate of to households’ income (ex. A means that 10% of households’ income goes to tax payments). a. What is the equation that describes the disposable income of households? b. What is the Planned Expenditure Equation? Assume that government expenditure is exogenous and Investment function is given by the equation I = I-br Where is the interest rate. c. Derive the equilibrium output in the goods market and show that the multiplier in this model is 1/1c(1-t). d. How does and the tax rate affects this multiplier (e.g., what happens to multiplier if c increases cet.par. , or if tax rate increases, cet.par)?
