Planned expenditure function question with lump-sum tax Do all parts to the question (show your work) Assume in Fantasticland, MPC = 0.75, and autonomous consumption = $6000. %3D Planned investment = $2000, and planned government purchases = $5000. All Planned I and G are autonomous expenditures. Taxes ( T) is = $1000, and net exports = zero. %3D а. Write out the consumption function b. What is induced consumption in this model С. Write out the planned expenditure function (show your work)

Given a consumption function, C = c0 + cY, specified such that the marginal propensity to consume is 75%, how much will C increase by if Y increases by £3bn? a. £0.75bnb. £2,250mc. £2bn d. £1,500m

Consider two economies, A and B. Economy A has a marginal propensity to consume of 0.9, a net tax rate of 0.2 and a marginal propensity to import of 0.2. Economy B has a marginal propensity to consume of 0.7, a net tax rate of 0.2 and a marginal propensity to import of 0.2. Suppose there is an increase in autonomous investment of $5 billion in each of these economies. Which of the following statements is true? Select one: O A. The AD curve shifts farther to the right in Economy A than Economy B. O B. The AD curve shifts to the left the same amount in both economies. O C. The simple multiplier is larger in Economy A. O D. The AD curve shifts to the right the same amount in both economies. O E. The AD curve shifts farther to the left in Economy B than Economy A.

If Andrea’s disposable income increases from $600 to $700 and her level of personal consumption expenditures increases from $450 to $475. You may conclude that her marginal propensity to consume is: Group of answer choices 0.5 0.1 0.75 0.25

Assume that specific functional forms are assumed for the consumption function and the investment demand function: C = c1(Y; – G;) + c2(Y;+1- G++1) – C3ri I = -dır: + d2At+1+ d3Kt Where c1, C2, c3, di, dzand d3are fixed parameters governing the sensitivity of consumption and investment to different relevant decision factors. a) Find an algebraic expression of the IS (Investment-Savings) curve. b) Use the above expression to find the slope of the IS curve. C) Assume that the parameter values are: C1 = 0.6, c2 = 0.5, c3 = 10, dı = 20, d2 = 1 and d3 = 0.5. Assume that Yt+1 = 15, Gt = 10, Gt+1 = 10, At+1 = 5 and Kt = 15. Assume that rt = 0.1. Find the product in the current period. d) Now suppose ri = 0.15. Find the product Y in the current period. (e) Create a range of values of r, between 0.01 to 0.2, with 0.001 intervals between values. Find Y for each r:using an Excel sheet and draw the IS curve. Does it have the expected slope? Comment f) Find another version of the IS curve with A…

Suppose a closed economy with no government spending or taxing is capable of producing an output of $1600 at full employment.  Suppose also that autonomous consumption is $120, intended investment is $160, and the mpc is 0.50.   What is the value of output (Y) in equilibrium?
