15. Other things equal, of a change in the tastes of American consumers causes them to purchase more foreign goods at each level of US GDP

A) Unemployment will decrease domestically

B) US GDP will fall
C) Inflation will occur domestically
D) US real GDP will rise

Answer 1

(5) (C)

Since AE values are for closed economy, this is a closed economy. Since value of government spending is given, this is a mixed economy.

(6) (D)

In equilibrium, Domestic output = AE for closed economy + Government spending, which is satisfied when

450 = 430 + 20

(7) (B)

In closed-economy equilibrium, Domestic output = AE for closed economy, which is satisfied when

350 = 350

(8) (D)

Marginal propensity to consume (MPC) = Change in Domestic output / Change in AE = (270 - 230) / (250 - 200) = 40/50

= 0.8

Multiplier = 1 / (1 - MPC) = 1 / (1 - 0.8) = 1/0.2 = 5
