At the end of each chapter is a series of Unit Exercises. Students are to complete the exercises in Word (or some other compatible word processor).
Question 1. Suppose you are given the following information for an economy without government spending, exports, or imports. C is desired consumption, I is desired investment, and Y is income. C and I are given by:
C = 1300 + 0.85Y
I = 450
What is the equation for the aggregate expenditure (AE) function?
Applying the equilibrium condition that Y = AE, determine the level of equilibrium national income.
Using your answer from part (b), determine the values of consumption, saving, and investment when the economy is in equilibrium.
Question 2. Consider the simplest macro model with demand-determined output.
The equations are:
C = 150 + 0.8Yd, Yd = Y-T,
I = 400, G = 700,
T = .2Y, X = 130, and
IM = 0.14Y.
What is the Marginal Propensity to Consume (MPC) in this model?
What is the Marginal Propensity to import?
What is the total autonomous expenditure?
What is the equilibrium GDP?
