C) The value of assets in Country B will increase relative to assets in Country A.
D) There will be no change in the flow of financial capital between the two countries.

The provided content states that 'Financial capital will flow toward the country with the relatively higher interest rate.' Therefore, capital will move from Country B (lower rate) to Country A (higher rate).
A) They directly alter the prices of exported and imported goods.
B) They change the relative values of domestic and foreign assets.
C) They force central banks to buy and sell foreign currency.
D) They reflect differences in government budget deficits.
Correct Answer: B
The text explicitly states, 'differences in real interest rates across countries change the relative values of domestic and foreign assets.' A higher interest rate makes a country's assets more attractive to investors, leading to capital inflows.
A) An increase in the supply of the country's currency, causing it to depreciate.
B) A decrease in the demand for the country's currency, causing it to depreciate.
C) An increase in the demand for the country's currency, causing it to appreciate.
D) A decrease in the supply of the country's currency, causing it to depreciate.
Correct Answer: C
A higher domestic real interest rate attracts foreign financial capital. To purchase domestic assets, foreign investors must first buy the domestic currency. This increases the demand for the currency in the foreign exchange market, causing it to appreciate.
A) It will increase the supply of loanable funds, decreasing the real interest rate.
B) It will decrease the supply of loanable funds, increasing the real interest rate.
C) It will increase the demand for loanable funds, increasing the real interest rate.
D) It will decrease the demand for loanable funds, decreasing the real interest rate.
Correct Answer: A
A net inflow of financial capital represents foreign savings entering the country's market. This increases the total pool of savings available for lending, which is represented as an increase (a rightward shift) in the supply of loanable funds, leading to a lower equilibrium real interest rate.
A) A net capital inflow, as domestic assets become more attractive.
B) A net capital outflow, as foreign assets become relatively more attractive.
C) No change in capital flows, as monetary policy only affects the domestic economy.
D) A net capital inflow, as the domestic currency appreciates.
Correct Answer: B
The text states that central banks can influence interest rates, which in turn affect net capital inflows. A lower domestic interest rate makes domestic assets less attractive compared to foreign assets, causing domestic and foreign investors to seek higher returns abroad, resulting in a net capital outflow.
A) Mexican interest rates fall, leading to a capital outflow and a depreciation of the peso.
B) Mexican interest rates fall, leading to a capital inflow and an appreciation of the peso.
C) Mexican interest rates rise, leading to a capital outflow and a depreciation of the peso.
D) Mexican interest rates rise, leading to a capital inflow and an appreciation of the peso.
Correct Answer: D
Contractionary monetary policy is designed to increase domestic interest rates. A higher real interest rate in Mexico makes Mexican assets more attractive, leading to a financial capital inflow. The resulting increase in demand for the Mexican peso on the foreign exchange market causes the peso to appreciate.
A) The country's real interest rates are relatively low compared to the rest of the world.
B) The country's real interest rates are relatively high compared to the rest of the world.
C) The country's central bank has recently increased its policy rate.
D) The demand for the country's currency has been increasing.
Correct Answer: A
Financial capital flows toward countries with higher real interest rates and away from countries with lower real interest rates. A net capital outflow indicates that the returns on domestic assets are less attractive than returns on foreign assets, which is caused by relatively lower domestic real interest rates.
A) The national debt.
B) The long-run rate of inflation.
C) Net capital inflows.
D) The level of structural unemployment.
Correct Answer: C
The provided text explicitly links the central bank's influence on domestic interest rates to its effect on net capital flows. The statement reads: 'Central banks can influence the domestic interest rate in the short run, which in turn will affect net capital inflows.'
A) A financial capital outflow from the United States and a depreciation of the U.S. dollar.
B) A financial capital inflow to the United States and an appreciation of the U.S. dollar.
C) A financial capital outflow from the United States and an appreciation of the U.S. dollar.
D) A financial capital inflow to the United States and a depreciation of the U.S. dollar.
Correct Answer: B
Higher real interest rates in the U.S. make U.S. assets more attractive. This causes a financial capital inflow as European and other investors seek higher returns. To buy U.S. assets, these investors must demand U.S. dollars, which causes the dollar to appreciate in the foreign exchange market.
