Question #5 An economy is described by the following relationships C 50+.75Y I 150 a. Compute the equilibrium level. b. Draw the AE diagram, and identify equilibrium income. c. Suppose autonomous consumption rises to 80. Graph the new aggregate expenditure curve. d. With autonomous consumption at 80, what is the new value of equilibrium income? e. Compute the value of the multiplier. f. Back to the original model. Suppose the marginal propensity to consume rises to 0.8. Graph the new aggregate expenditure curve. g. With marginal propensity to consume equal to 0.8, what is the value of equilibrium income?
