    "What Determines Exchange Rates?",
    "Since the general shift to floating exchange rates in the early 1970s, exchange rates between the U.S. dollar and other major currencies have been variable or volatile. The charts at the beginning of the chapter suggest three types of variability. First, there are long-term trends in which some currencies tend to appreciate against the dollar, and others tend to depreciate. Second, there are medium-term trends which are sometimes counter to the longer trends. Third, there is substantial variability during the short run. The chapter presents what we know about exchange movements during these time periods of different lengths.",
    "The chapter first examines short-run movements in exchange rates. It presents the version of the asset market approach to exchange rates that focuses on debt securities and the uncovered interest parity relationship developed in Chapter 18, presuming that this relationship holds approximately if not exactly. The basic discussion examines the pressure on the current spot exchange rate if one of the other three rates (the domestic interest rate, the foreign interest rate, and the expected future spot exchange rate) changes, with the other two held constant. If the domestic interest rate increases, then the foreign currency depreciates (the home currency appreciates). If the foreign interest rate increases, then the foreign currency appreciates. (The text notes that what really matters is the change in the interest differential.)",
    "If the expected future spot exchange rate value of the foreign currency increases, then the current spot exchange rate value of the foreign currency increases. Many different things can influence the expected future spot exchange rate. First, if expectations simply extrapolate recent trends, then a bandwagon is possible. Speculation then may be based on destabilizing expectations—expectations formed without regard to the economic fundamentals—and (speculative) bubbles can occur. Second, if expectations are based on a belief that exchange rates eventually follow PPP, then they lead to stabilizing speculation—speculation that tends to move the exchange rate toward a value consistent with the economic fundamentals of national price levels. Third, expectations are affected by various kinds of news about economic and political circumstances."

It presents the version of the asset market approach to exchange rates that focuses on debt securities and the uncovered interest parity relationship developed in Chapter 18, presuming that this relationship holds approximately if not exactly. The basic discussion examines the pressure on the current spot exchange rate if one of the other three rates (the domestic interest rate, the foreign interest rate, and the expected future spot exchange rate) changes, with the other two held constant.\n- 支撑要点：Exchange rates over time\n- 支撑要点：Long-term trends\n- 支撑要点：Medium-term trends\n- 来源类型：manual\n\n## 案例\n### 案例 1: 2.Calculate and report the real bilateral exchange rate values (annual a ...\n2.Calculate and report the real bilateral exchange rate values (annual averages) of your country's currency since 1990, relative to the U.S. dollar. If possible, use price indexes called “Producer Prices,” “Wholesale Prices,” or a similar name, even if the names are somewhat different between your country and the United States.\n\n### 案例 2: Price Gaps and International Income Comparisons: The list of countries i ...\nPrice Gaps and International Income Comparisons: The list of countries is ordered by national income per capita using common prices (sometimes called national income per capita at PPP exchange rates), as shown in the middle column of numbers. Singapore is at the top of the list because it has the highest value for this common-price income per capita.\n\n### 案例 3: 11. a.If we use 1995 as the base year, the nominal ...\n11. a.If we use 1995 as the base year, the nominal exchange rate of $1/pnut corresponds to a ratio of U.S. prices to Pugelovian prices of 100/100. According to PPP, this relationship should be maintained over time. If the price level ratio changes to 260/390 in 2018, then the nominal exchange rate should change to $0.67/pnut.\n\n### 案例 4: b.For the United States, the quantity theory of money with a ...\nb.For the United States, the quantity theory of money with a constant k means that the quantity equation with k = 0.25 should hold in 2018: 65,000 = 0.25 260 1,000. It does. Because the quantity equation holds for both years with the same k, the change in the price level from 1995 to 2018 is consistent with the quantity theory of money with a constant k.\n\n## 习题\n### 题目 1\nThe ________ approach to exchange rates emphasizes the role of portfolio repositioning by international financial investors.\n- A) elasticity\n- B) asset market\n- C) monetary\n- D) balance-of-payments\n\n### 题目 2\nThe asset market approach to exchange rate determination seeks to predict\n- A) the forward exchange rate premiums.\n- B) the long-run trends in exchange rates.\n- C) the possibility of retaining a pegged exchange rate by the government.\n- D) the short-term pressures on exchange rates.\n\n### 题目 3\nThe exchange rate value of a foreign currency is ________ in the short run by a rise in its expected future spot exchange rate value.\n- A) raised\n- B) lowered\n- C) made volatile\n- D) not affected\n\n### 题目 4\nA decrease in the foreign interest rate relative to the domestic interest rate ________ the exchange rate value of a foreign currency in the short run.\n- A) raises\n- B) lowers\n- C) does not affect\n- D) causes fluctuations in\n\n### 题目 5\nOther things equal, a broad shift to expecting depreciation of the euro will lead to\n- A) an inflow of capital to Europe.\n- B) an increase in official exchange market intervention by the euro area monetary authorities.\n- C) a lowering of exports of European goods and services.\n- D) a decrease in the demand for euro-denominated financial assets.\n\n### 题目 6\nIf the domestic interest rate decreases, with the foreign interest rate and the expected future spot rate remaining unchanged, the value of the domestic currency vis-à-vis the foreign currency is expected to\n- A) increase.\n- B) decrease.\n- C) remain unchanged.\n- D) converge to its purchasing power parity (PPP) value.\n\n### 题目 7\nIf the expected future spot exchange rate value of the foreign currency decreases, with the interest rate differential unchanged, the current spot exchange-rate value of the domestic currency\n- A) increases.\n- B) decreases.\n- C) remains unchanged.\n- D) overshoots.\n\n### 题目 8\nWhich of the following statements is true?\n- A) If the domestic interest rate rises, there will be international financial repositioning toward domestic-currency assets, thereby causing the domestic currency to appreciate.\n- B) If the expected future spot exchange rate value of the foreign currency decreases, there will be international financial repositioning toward foreign-currency assets, thereby causing the domestic currency to depreciate.\n- C) If foreign interest rates increase, the domestic interest rate remaining unchanged, there will be international financial repositioning toward domestic-currency assets and the domestic currency will appreciate.\n- D) If the expected future spot dollar per euro exchange rate increases, there will be international financial repositioning toward the dollar-denominated assets thereby causing the euro to depreciate.\n\n## 参考答案\n- 题目 1: 答案：B | 选项内容：asset market | Topic：A Road Map | Difficulty：1 Easy\n- 题目 2: 答案：D | 选项内容：the short-term pressures on exchange rates. | Topic：A Road Map | Difficulty：1 Easy\n- 题目 3: 答案：A | 选项内容：raised | Topic：Exchange Rates in the Short Run | Difficulty：1 Easy\n- 题目 4: 答案：B | 选项内容：lowers | Topic：Exchange Rates in the Short Run | Difficulty：1 Easy\n- 题目 5: 答案：D | 选项内容：a decrease in the demand for euro-denominated financial assets. | Topic：Exchange Rates in the Short Run | Difficulty：1 Easy\n- 题目 6: 答案：B | 选项内容：decrease. | Topic：Exchange Rates in the Short Run | Difficulty：2 Medium\n- 题目 7: 答案：A | 选项内容：increases. | Topic：Exchange Rates in the Short Run | Difficulty：2 Medium\n- 题目 8: 答案：A | 选项内容：If the domestic interest rate rises, there will be international financial repositioning toward domestic-currency assets, thereby causing the domestic currency to appreciate. | Topic：Exchange Rates in the Short Run | Difficulty：2 Medium\n\n## AI / NextLab 使用建议\n- Mundell Trilemma Lab：将《What Determines Exchange Rates?》对应的理论或政策机制放到贸易分析实验室中做交互式验证。 https://digitconnection.ai/nextlab/\n",
