Question 1

If a nation's interest rates are relatively low compared to those of other countries, then the exchange value of its currency will tend to

Accepted Answer

When a nation's interest rates are relatively low compared to those of other countries, investors may seek higher returns by investing their money in other countries with higher interest rates, leading to a decrease in demand for the nation's currency and a depreciation in its exchange value. This is more likely to happen under a system of floating exchange rates, as the currency's value is determined by the market forces of supply and demand.

Question 2

If the Fed increases the money supply to fight recession, a floating exchange rate will aid the Fed in fighting recession because

Accepted Answer

When the Fed increases the money supply, it reduces the interest rate, making borrowing cheaper and encouraging businesses and consumers to spend more, which in turn stimulates economic growth. However, this can also lead to inflation. If the exchange rate is floating, as the interest rate decreases, the value of the domestic currency falls relative to other currencies, making exports cheaper and imports more expensive. This results in a decrease in imports and an increase in exports, which can help to reduce the trade deficit and boost economic growth. Therefore, the floating exchange rate can aid the Fed in fighting recession by mitigating the risk of inflation and promoting export-led growth.

Question 3

The ________ the economy and ________ exchange rates increase the effectiveness of both expansionary and contractionary monetary policies.

Accepted Answer

The openness of an economy refers to the degree to which it engages in international trade and financial transactions. A more open economy, with higher levels of trade and financial flows, tends to have more responsive exchange rates to changes in monetary policy. This means that both expansionary and contractionary monetary policies are more effective in influencing economic activity. However, the flexibility of exchange rates also plays a role in this effectiveness. Flexible exchange rates allow market forces to adjust exchange rates in response to changes in monetary policy, which can enhance the effectiveness of those policies. Therefore, the best choice is C, which identifies the importance of both the openness of the economy and the flexibility of exchange rates in increasing the effectiveness of monetary policy.

Question 4

In the foreign exchange market between the Mexican peso and the U.S. dollar, an excess supply of Mexican pesos will result in a depreciation of the Mexican peso relative to the U.S. dollar.

Accepted Answer

An excess supply of Mexican pesos means there are more pesos available for exchange than there is demand for them. This decreased demand causes the value of the Mexican peso to decrease and therefore depreciate relative to the U.S. dollar.

Question 5

A Big Mac costs $3 in the United States and 50 pesos in Mexico. The purchasing power parity theory would predict that the exchange rate in the long run is

Accepted Answer

According to the purchasing power parity theory, exchange rates should adjust so that a basket of goods in one country costs the same in another country after accounting for the exchange rate. In this case, we can use the price of a Big Mac in the United States and Mexico to estimate the exchange rate. If a Big Mac costs $3 in the United States and 50 pesos in Mexico, then the exchange rate should be $1 = 16.67 pesos ($3 divided by 50 pesos). Therefore, the best choice is B.

Question 6

The effect of a sustained increase in government spending or investment on aggregate output is larger in an open economy than in a closed economy.

Accepted Answer

In an open economy, a portion of the increased spending leaks out through imports, reducing the multiplier effect on aggregate output compared to a closed economy where all spending circulates within the economy, amplifying its impact.

Question 7

The theory of international exchange that holds that exchange rates are set so that the prices of ________ goods in different countries is ________ is the purchasing power parity theory.

Accepted Answer

The purchasing power parity theory states that exchange rates will adjust in order to make the price of similar goods the same across different countries. Therefore, option A is correct as it states that the goods in different countries will be similar in price. Option C is incorrect as it states that the prices of different goods will be the same, which is not what the theory says. Options B and D are also incorrect as they do not accurately describe the theory of purchasing power parity.

Question 8

Fiscal policy is more effective when the exchange rate is flexible and the economy is open.

Accepted Answer

Fiscal policy tends to be more effective in a closed economy or when the exchange rate is fixed because the impact of government spending or taxation is less likely to be diluted through changes in net exports or exchange rates. In an open economy with a flexible exchange rate, fiscal expansion can lead to currency appreciation, which can reduce net exports and offset the fiscal stimulus.

Question 9

Purchasing power parity theory holds that exchange rates are set so that the price of similar goods in different countries reflects the relative interest rates in those countries.

Accepted Answer

Purchasing power parity theory holds that exchange rates are set so that the price of similar goods in different countries reflects the relative purchasing power of those countries, not necessarily the relative interest rates.

Question 10

Suppose that the price of a Blu-ray disc player is $240 in the United States and 11,000 rupees in India. If the current exchange rate is 40 rupees to the dollar, then purchasing power parity theory would predict that in the long run

Accepted Answer

The answer of Suppose that the price of a Blu-ray...

Question 11

Expansionary monetary policy causes the exchange rate to depreciate.

Accepted Answer

Expansionary monetary policy involves increasing the money supply and lowering interest rates, which makes the domestic currency less attractive and can lead to a decrease in its value relative to other currencies. This results in a depreciation of the exchange rate.

Question 12

Monetary policy is more effective when the exchange rate is flexible and the economy is open.

Accepted Answer

When the exchange rate is flexible, it adjusts to changes in the economy, making monetary policy more effective. Additionally, when the economy is open, there is more trade and capital flows, which also affect exchange rates, making monetary policy more impactful. In contrast, when the exchange rate is fixed or pegged to another currency, monetary policy may be less effective as changes in interest rates may not result in changes in the exchange rate.

Question 13

Why does the appreciation of a country's currency tend to decrease its price level?

Accepted Answer

A currency appreciation makes imported inputs less expensive, reducing production costs and potentially leading to lower prices for goods and services domestically.

Question 14

________ suggests that the depreciation of a nation's currency may have an ambiguous effect on its balance of trade.

Accepted Answer

The J-curve effect suggests that in the short run, a depreciation of a nation's currency may worsen the balance of trade due to higher prices of imports and lower competitiveness of exports. However, in the long run, the balance of trade may improve due to increased export competitiveness and potential decreases in import demand. Therefore, the effect on the balance of trade is ambiguous.

Question 15

The law of one price states that if the costs of transportation are small, then the price of the same good in different countries should be roughly the same.

Accepted Answer

The law of one price states that if the costs of transportation are small, then the price of the same good in different countries should be roughly the same. This is because if the price is significantly different, it creates an opportunity for arbitrage, where individuals can buy the good in the country where it is cheaper and sell it in the country where it is more expensive, making a profit. The ability to engage in arbitrage should drive the prices towards being equal.

Question 16

Which of the following policies tends to cause the dollar to depreciate?

Accepted Answer

The answer of Which of the following policies tends to...

Question 17

Monetary policies are

Accepted Answer

Monetary policies tend to be more effective in an open economy with a flexible exchange rate because the central bank can use its tools to influence the economy without worrying about maintaining a fixed exchange rate. This flexibility allows for more direct control over domestic economic conditions.

Question 18

Contractionary monetary policy

Accepted Answer

Contractionary monetary policy, which typically involves raising interest rates, tends to attract foreign capital due to the higher returns on investments. This increased demand for the nation's currency to invest in these higher-yielding assets leads to an appreciation of the currency.

Question 19

If the exchange rate between the British pound and the U.S. dollar was $1 = £0.67 last month, and the exchange rate is $1 = £0.72 this month, the U.S. dollar has appreciated relative to the British pound.

Accepted Answer

The U.S. dollar has appreciated because it now exchanges for more British pounds (£0.72) than it did last month (£0.67), indicating an increase in its value relative to the pound.

Question 20

The observation that the trade balance usually gets worse before it improves after a currency depreciation is referring to the

Accepted Answer

This is known as the J-curve effect, which refers to the initial worsening of the trade balance following a currency depreciation, but then an eventual improvement as the economy adjusts.
