1. Openness in the Goods Market (19 Points)
Let us consider a domestic open economy described as follows:
C = 10 + 0.5(Y-T) IM/e = 0.2Y
I = 3 + 0.3Y X = 0.3Y*/e
G=10
where e stands for the real exchange rate defined as the price of one unit of the domestic good in terms of foreign goods and Y* stands for the foreign output/income. The government budget deficit is equal to 2% of the domestic output/income denoted by Y.
a. Write down the equation of the net exports schedule (NX) for the above domestic economy. Does the Marshall-Lerner condition hold? (4 Points)
b. Write down the domestic goods market equilibrium condition. Solve for the domestic equilibrium output/income Y given Y* and e. (3 Points)
c. Under the assumption that the foreign output/income expressed in terms of the domestic goods is half the size the domestic output/income, compute the equilibrium domestic output/income. (4 Points)
d. Does the domestic economy run a trade surplus or a trade deficit in equilibrium? (2 Points)
