Question 2

For an open economy,which of the following expressions represents net exports (NX)?

Accepted Answer

Net exports (NX) are defined as the difference between a country's total exports and total imports. None of the options provided (A, B, C, D) accurately represent this definition. These options mix various components of the national income accounts (such as savings (S), government spending (G), taxes (T), and investment (I)) in ways that do not correspond to the calculation of net exports.

Question 3

For an open economy,which of the following expressions represents saving (S)?

Accepted Answer

The answer of For an open economy,which of the following...

Question 4

Suppose policy makers want to increase Y and increase NX.Which of the following policies would most likely achieve this?

Accepted Answer

A real depreciation (which means making the currency of the country cheaper relative to foreign currencies) would make exports cheaper and imports more expensive. This would increase net exports (NX) and also increase aggregate demand, leading to an increase in output (Y). Option A may increase output but may not affect the net exports. Option C may increase net exports but may have an uncertain effect on output. Option D, an increase in the real exchange rate, would make exports more expensive and imports cheaper and would work against the policy objective of increasing net exports.

Question 5

Assume the Marshall-Lerner condition holds.Which of the following will cause a reduction in net exports?

Accepted Answer

An increase in the real exchange rate will make exports relatively more expensive and imports relatively cheaper, which will lead to a decrease in net exports. The other options may have an impact on the economy, but they do not directly affect the exchange rate and the balance of trade.

Question 6

We will generally observe that the less open an economy

Accepted Answer

In a less open economy, fiscal policy has a larger effect on output because there is less leakage through imports, but a smaller effect on the trade position because the economy is less engaged in international trade.

Question 10

For this question,assume that the Marshall-Lerner condition does not hold.A reduction in the real exchange rate will tend to cause which of the following to occur?

Accepted Answer

When the Marshall-Lerner condition does not hold, a reduction in the real exchange rate does not necessarily lead to predictable changes in net exports (NX) or domestic/foreign output (Y/Y*). The Marshall-Lerner condition states that a devaluation (or depreciation) of a country's currency will only lead to an improvement in the trade balance if the sum of the price elasticities of demand for imports and exports is greater than one. If this condition does not hold, the effects of changes in the real exchange rate on NX and output can be ambiguous, making none of the provided options universally correct.

Question 12

We will generally observe that the more open an economy

Accepted Answer

In more open economies, fiscal policy tends to have a smaller effect on output because a significant portion of increased spending leaks out through imports rather than stimulating domestic production. However, this increased demand for imports worsens the trade position, leading to a larger effect of fiscal policy on the trade balance.

Question 14

For this question,assume that equilibrium output is determined in the ZZ-Y diagram.Further assume that policy makers' goals are (1)to achieve balanced trade (i.e.,NX = 0); and (2)to achieve a target level of output,say Yᵀ.Now,suppose that the initial level of equilibrium output is equal to Yᵀ (i.e.,Y = Yᵀ)and that a trade deficit exists at this initial level of output.Which of the following policy actions would most likely enable the policy makers to achieve their two goals simultaneously?
A)a reduction in government spending
B)convince the country's trading partners to pursue policies that will cause an increase in foreign income (Y*)
C)a reduction in the real exchange rate
D)a reduction in taxes
E) a simultaneous increase in government spending and reduction in the real exchange rate 
F) none of the above

Question 16

In a large country,the effect of a given change in government spending

Accepted Answer

In a large country, a change in government spending typically has a significant impact on output due to the size of the economy and the multiplier effect. However, the effect on the trade balance is relatively small because the domestic market absorbs most of the impact, and changes in trade flows are a smaller proportion of the total economy.

Question 17

Suppose there is a real appreciation.This real appreciation is more likely to cause a reduction in net exports when

Accepted Answer

A real appreciation typically makes exports more expensive for foreign buyers and imports cheaper for domestic buyers. Therefore, a reduction in net exports is more likely to occur when both exports and imports are relatively sensitive to price changes (i.e. elasticity of demand is high), making the impact of price changes more pronounced.

Question 18

In a small country,the effect of a given change in government spending

Accepted Answer

In a small open economy, changes in government spending have a limited impact on output due to the economy's reliance on international trade, but they can significantly affect the trade balance.

Question 19

Using the ZZ / Y and NX graphs,illustrate graphically and explain what effect an increase in foreign output (Y*)will have on output,exports,imports,and net exports.Clearly label all curves and clearly label the initial and final equilibria.
