Answer to Question 1

E

Answer to Question 2

The multiplier is 5.
a. The change in equilibrium aggregate expenditure equals the multiplier times the change in autonomous expenditure, which is 0.5 trillion. So the change in equilibrium expenditure is .
b. The change in equilibrium aggregate expenditure equals the multiplier times the change in autonomous expenditure, which is -0.2 trillion, that is, government expenditures decrease by . So the change in equilibrium expenditure is 5  (-0.2 trillion) = -1.0 billion.
c. The change in equilibrium aggregate expenditure equals the multiplier times the change in autonomous expenditure, which is 1.1 trillion. So the change in equilibrium expenditure is .
