Demonstrate and explain Hint Formula from Module C= a MPC* Yd where Yd is disposable income.

1. Assume in a simple economy that the level of saving is –500 when aggregate output equals zero and that the marginal propensity to save is 0.2. Derive the saving function and the consumption function, and draw a graph showing these functions. At what level of aggregate output does the consumption curve cross the 45° line? Explain your answer and show this on the graph.2. Use your answer to the previous problem to calculate the MPC, MPS, government spending multiplier, and tax multiplier. Draw a graph showing the data for consumption spending, planned aggregate expenditures, and aggregate output. Be sure to identify the equilibrium point on your graph. Sorry, these two questions are linked. I totally forgot.
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)?
If Multiplier is 1/1-MPC and MPS+MPC=1, MPC= Marginal propensity to consume and MPS= marginal propensity to save. Using this formula and MPC is 0.9 multiplier is __________ and if MPS =0.4 multiplier is ________________ a 10 and 10 b 1 and 2.5 c 10 and 2.5 d 1.111 and 1.666
16. Suppose that planned investment and planned government purchases do not depend on income:I = 15 and G = 17. Consumption, as you would expect, does depend on income via the consumption function C = 2 + 0.75Y – 0.75T. Net taxes are T = 12. Your friend thinks that the equilibrium will be where Y = 150 but he is wrong. What is the best description of this situation? a. the (Y, AE) point is above the 45 degree line, Y will adjust down b. the (Y, AE) point is above the 45 degree line, Y will adjust up c. the (Y, AE) point is below the 45 degree line, Y will adjust down d. the (Y, AE) point is below the 45 degree line, Y will adjust up 17. (continued) Help you friend by calculating the equilibrium income for the AE model in the previous question. Y = _____
