Q

The Bank of England decides to stabilize the British pound against the euro due to an unexpected depreciation. Explain how the central bank would conduct a non-sterilized intervention and how this might affect the domestic money supply and interest rates.

A
  • Non-sterilized Intervention: Central bank buys GBP (selling euros), increasing GBP demand.
  • Money supply impact: Increases domestic money supply.
  • Interest rates: Likely decrease due to higher money supply.

Q

Imagine a country with a fixed exchange rate suddenly experiences a speculative attack on its currency. Describe two measures the central bank could take to defend the peg and explain potential consequences for the economy.

A

Measures:
- Sell foreign reserves to buy domestic currency.
- Raise interest rates to attract foreign investment.

Consequences:
- Depleted reserves might lead to abandoning the peg.
- Higher interest rates may slow economic growth.

Q

If the European Central Bank (ECB) intervenes in the forex market to strengthen the euro but wishes to avoid altering the eurozone’s money supply, what actions constitute a sterilized intervention? Why might the ECB prefer sterilized interventions?

A

Sterilized Intervention Steps:
- Buy euros in forex markets (direct intervention).
- Sell government securities domestically to offset increased money supply.

Preference: Maintains stability of domestic money supply and interest rates.

Q

A developing country decides to adopt a fixed exchange rate to the US dollar to stabilize inflation. Discuss the benefits and risks of this decision, using Argentina’s experience in the 1990s as an example.

A

Benefits:
- Currency stability reduces inflation.
- Encourages foreign investment.

Risks:
- Loss of monetary policy independence.
- Vulnerable to external shocks (e.g., US policy shifts).

Example: Argentina’s currency board (1991) succeeded initially but collapsed due to rigid policies amid economic crises.

Q

A central bank initially uses non-sterilized intervention to prevent the appreciation of its currency but faces a risk of inflation due to the increased money supply. It then conducts sterilized intervention by selling government bonds in the open market.

a) Explain the sequence of effects on the domestic money supply, interest rates, and exchange rate resulting from this sterilized intervention.

b) Critically evaluate why this approach might fail to achieve the desired weaker exchange rate.

A

a)Selling bonds reduces money supply, increasing interest rates.Higher interest rates attract capital inflows, leading to currency appreciation.

b)Sterilized interventions lack lasting economic impacts.Traders might view the intervention as non-credible and expect the currency to revert.

Q

The Bank of England engages in sterilized intervention by selling pounds in the forex market but also uses public statements to signal its preference for a weaker pound.

a) Discuss the psychological mechanisms by which the central bank’s actions might influence trader behavior in the short term.

b) Analyze why this psychological effect might be temporary without accompanying changes in interest rates or money supply.

A

a)Traders interpret the central bank’s signals as a call to sell pounds, amplifying market movements.This can lead to short-term depreciation as traders align expectations with policy.

b)Lack of structural economic changes undermines the intervention’s credibility.Traders may anticipate a reversal of depreciation, reducing the intervention’s effectiveness.

Q

Using the scenario where the pound initially appreciates from 1.35 to 1.50 USD/GBP despite sterilized interventions, critically evaluate:

a) Why sterilized interventions are generally less effective than non-sterilized interventions for achieving exchange rate objectives.

b) Under what circumstances might a central bank still prefer sterilized interventions over non-sterilized ones?

A

a)Sterilized interventions do not alter money supply or interest rates, limiting their impact.Traders often discount these interventions due to a lack of commitment to economic shifts.

b)Sterilized interventions minimize inflationary pressures and maintain domestic monetary stability.Useful for signaling policy intentions without creating distortions in the domestic economy.

Q

Central banks and commercial banks both participate in forex markets, but their objectives differ significantly.

a) Contrast the goals of central banks with those of commercial banks when participating in the forex market.

b) Provide an example where central bank intervention in the forex market might conflict with the goals of commercial banks.

A

a)Central Banks: Stabilize currency, control inflation, support exports.Commercial Banks: Profit from trading and facilitate client transactions.

b)Example: Central bank intervention to weaken currency might reduce commercial banks’ forex trading profitability by creating volatility.

Q

Retail clients, such as multinational corporations and international investors, rely on intermediaries to access the forex market.

a) Explain why retail clients do not directly participate in the forex market and the advantages of using commercial banks as intermediaries.

b) Consider a scenario where a multinational corporation hedges currency risk using a commercial bank. What are the potential risks if the bank fails to manage the transaction efficiently?

A

a)Retail clients lack scale and expertise for direct trading.Banks offer liquidity, better pricing, and hedging instruments.

b)Risks: Hedging failure, exposure to unexpected currency movements, and potential financial loss.

Q

The nominal exchange rate between USD and JPY is 140 JPY/USD. The US consumer price index is 120, and Japan’s consumer price index is 100.

a) Calculate the real exchange rate.

b) Discuss what the real exchange rate indicates about US price competitiveness compared to Japan.

A

a) Real Exchange Rate: Sr=S×P/P∗=140×120/100=168

b) Indicates US goods are relatively more expensive than Japanese goods, reducing competitiveness.

Q

Explain how the effective exchange rate (EER) might overstate or understate the impact of exchange rate movements on a country’s trade balance. Use the example of a country heavily trading with a single partner whose currency experiences significant volatility.

A
  • EER uses weighted averages but may not capture full impact if trade is concentrated in one partner.
  • Example: A 20% appreciation against one partner (e.g., US) could severely impact competitiveness if the country conducts 90% of trade with the US, even if the EER shows a smaller overall change.

Q

Discuss how changes in the domestic and foreign inflation rates impact the real exchange rate, even if the nominal exchange rate remains constant. Provide an example of a country experiencing higher inflation than its trading partner.

A
  • Real exchange rate rises (currency becomes less competitive) if domestic inflation exceeds foreign inflation.
  • Example: If US inflation is 5% while Japan’s is 1%, US goods become relatively more expensive, reducing export competitiveness.

Q

Critically evaluate the limitations of using nominal and real exchange rate indices to measure a country’s international competitiveness. Provide examples of scenarios where each might fail to provide accurate insights.

A

-Nominal: Does not account for price level differences (e.g., a nominal depreciation might not reflect improved competitiveness if domestic inflation is high).

-Real: Lag in data availability can obscure real-time insights (e.g., monthly CPI updates delay competitiveness assessment).

Q

Suppose US income rises significantly due to economic growth.

a) Illustrate and explain the impact on the demand curve for pounds in the forex market.

b) Discuss how this would affect the spot exchange rate between the pound and the dollar, and the competitiveness of UK exports.

A

a) Higher US income increases demand for UK exports, shifting the demand curve for pounds rightward.

b) Pound appreciates, making UK exports more expensive and less competitive in the US market.

Q

If the UK experiences a rise in income, explain using a supply-demand framework how this affects the supply of pounds in the forex market and the spot exchange rate. Include implications for the UK trade balance.

A

Rise in UK income increases demand for US goods, shifting the supply curve of pounds rightward.

Pound depreciates, improving UK export competitiveness but worsening the trade balance due to higher imports.

Q

Explain how a shift in US consumer preferences toward UK goods impacts the spot exchange rate. Provide a real-world example of a scenario that could lead to such a preference shift.

A

Increased US demand for UK goods shifts the demand curve for pounds rightward, leading to pound appreciation.

Example: US consumers demand more UK luxury items (e.g., Burberry) after a major international campaign.

Q

A UK trader must pay $100,000 in one year. The spot rate is $1.25/£1, and the forward rate is $1.30/£1.

a) Calculate the cost of using a forward contract versus relying on the spot market if the spot rate in one year is $1.20/£1.

b) Explain why the trader might choose the forward contract despite the potential for a better spot rate in the future.

A

a)Forward: $100,000 ÷ $1.30 = £76,923.Spot: $100,000 ÷ $1.20 = £83,333.Forward saves £6,410.

b) The trader avoids exchange rate risk and gains certainty for budgeting.

Q

The spot exchange rate is $1.40/£1, and the forward rate is $1.35/£1. Discuss how interest rate differentials between the US and UK explain the forward discount on the pound.

A

Forward discount arises because UK interest rates are higher than US interest rates. Investors require compensation to hold lower-yield US dollars.

Q

The UK raises interest rates, making pound-denominated assets more attractive to US investors. Simultaneously, the US economy slows, reducing demand for UK exports.

a) Analyze the net impact on the pound’s spot exchange rate using supply-demand analysis.

b) Explain how these conflicting forces could stabilize the exchange rate in the short run.

A

a) Higher UK interest rates increase demand for pounds, appreciating the pound. Reduced UK export demand decreases pound demand, potentially offsetting appreciation.

b) The opposing effects can balance the exchange rate if magnitudes are similar.

Q

Explain how a change in the forward rate affects the spot rate in the context of CIP, using the example of a forward premium increasing from 2% to 4%.

A

Higher forward premium implies increased demand for foreign currency in spot markets.

Arbitrage ensures that rising forward demand pushes up the spot rate until CIP equilibrium is restored.

Q

Suppose the U.S. interest rate is 3% and the U.K. interest rate increases from 4% to 5%. The spot exchange rate is $1.30/£1, and the forward rate is $1.28/£1.

a) Explain how arbitrageurs would react to the increase in r∗r^*r∗, ensuring that CIP is reestablished.

b) Illustrate the sequence of market adjustments in both the spot and forward markets.

A

a) Arbitrageurs would exchange USD for GBP to invest in higher-yielding U.K. assets.

b) Sequence:Increased demand for GBP in the spot market → spot rate increases.Arbitrageurs enter forward contracts to hedge exchange rate risk → forward supply of GBP increases.Forward rate adjusts until (1+r)=(1+r∗)⋅(F/S), reestablishing CIP.

Q

Arbitrageurs investing in foreign assets are exposed to exchange rate risk.

a) Discuss how forward contracts mitigate this risk in the context of CIP.

b) Analyze the impact of arbitrage activity on the forward exchange rate and explain why this ensures that CIP holds in efficient markets.

A

a) Forward contracts lock the future exchange rate, eliminating uncertainty in converting foreign returns back to domestic currency.

b) Impact of arbitrage:Increased supply of foreign currency in the forward market reduces the forward premium or increases the forward discount.Adjustments in forward and spot rates ensure (1+r)=(1+r∗)⋅(F/S), closing arbitrage opportunities.

Q

A German automobile company has a factory in the United States, while a U.S.-owned technology firm operates a factory in Mexico.

a) Which of these would be included in U.S. GDP and U.S. GNP?

b) Explain the distinction between GDP and GNP with examples.

A

a) U.S. GDP: Includes production from both factories because GDP considers location.

b) GNP focuses on ownership:Production from a U.S.-owned firm in Mexico contributes to U.S. GNP but not U.S. GDP.Production from a German firm in the U.S. contributes to U.S. GDP but not U.S. GNP.

Q

Why is Gross National Disposable Income (GNDI) considered a better indicator of a nation’s actual income available for consumption and investment compared to GDP? Use examples of net unilateral transfers in your response.

A

GNDI includes net unilateral transfers (e.g., remittances, foreign aid) and net factor income from abroad.

Example: A country receives $2 billion in remittances from citizens working abroad. This directly boosts disposable income for consumption and savings.

GDP doesn’t capture these transfers, making GNDI a fuller measure.

Under what circumstances would GDP equal GNDI, and what happens when net factor income or net unilateral transfers are non-zero?

A

When GDP = GNDI: Net factor income abroad and net unilateral transfers = 0.

When these are non-zero: GNDI adds these flows to GDP to represent the total income available to a nation’s residents.

Q

Compare the role of national savings in a closed economy versus an open economy. Use real-life examples to illustrate the differences.

A

Closed Economy: All national savings are used for domestic investment. Example: In a country with no international trade, all savings would only finance local projects.

Open Economy: National savings can be used for domestic or foreign investment. Example: U.S. savings can finance domestic infrastructure projects or invest in foreign markets like European bonds.

Q

When a country has a current account deficit, how is this linked to borrowing from abroad and capital outflows?

A

Trade Deficit (CA < 0): Spending exceeds earnings; financed by borrowing or selling assets abroad.
Example: The U.S. has run consistent trade deficits, financing these deficits by selling bonds to foreign investors like China. These are asset outflows.

Q

Explain the mechanisms through which a country with a current account deficit borrows from abroad. How does this impact capital flows?

A

A country with a CA deficit borrows by selling financial assets, such as bonds and stocks, to foreign investors.

This leads to capital inflow from foreign investment to support the deficit. Example: The U.S. sells Treasury bonds to China to finance its deficit, leading to increased capital flows into the U.S.

Q

If S−I+T−G<0, what does this indicate about a nation’s national savings in comparison to its spending? What are the broader economic implications?

A

It indicates that a country’s savings are insufficient to finance its investment and government spending without borrowing.

Implications: Increased debt from borrowing, reliance on foreign financing, and vulnerability to currency fluctuations.

Example: The United States has historically borrowed from foreign countries to maintain its imports.

Q

How do capital flows (borrowing and lending) affect the balance of payments?

Capital flows represent the movement of financial assets (e.g., bonds, stocks, loans) across borders.

They are linked to trade deficits and surpluses.

Example: China’s capital flows into U.S. Treasury bonds (borrowing by the U.S.) finance America’s trade deficits by providing capital.

Identify and classify the following transactions into the appropriate section (and sub-account) of the balance of payments:
i. A US-based company exports software services to a client in Germany.
ii. A foreign investor purchases shares in a Japanese corporation.
iii. A government forgives $1 billion of debt owed by a developing country.
iv. An Indian citizen working in Saudi Arabia sends remittances back home.
v. The central bank of China increases its holdings of US Treasury bonds.

A

i. Current Account - Services Account: Software services are an intangible export.
ii. Capital and Financial Account - Portfolio Investment: Purchasing shares falls under portfolio investments.
iii. Capital and Financial Account - Capital Transfers: Debt forgiveness is considered a transfer of asset ownership.
iv. Current Account - Unilateral Transfers Account: Remittances are one-way income flows.
v. Official Reserves Account: Central bank holdings of foreign assets are recorded here.

43
Q

How would an increase in unilateral transfers (e.g., remittances sent from abroad) affect the current account balance of a country like Mexico?

A

An increase in remittances (a component of unilateral transfers) would improve Mexico’s current account balance as these are inflows of funds. For example, if Mexican workers in the US send more money back home, it raises disposable income for households, boosting consumption and potentially contributing to economic growth. However, heavy reliance on remittances can expose the economy to risks if inflows decline.

44
Q

Consider a scenario where political instability causes capital flight from a developing country. How would this affect the capital account and official reserves account? What might be the short-term and long-term economic consequences?

A

Capital flight would reduce the capital account surplus as foreign and domestic investors withdraw funds. If the central bank intervenes to stabilize the currency, official reserves would decrease. Short-term impacts include currency depreciation and inflation; long-term consequences could involve reduced foreign investment and slower growth.

45
Q

a) Explain what happens when a country experiences a BoP surplus versus a BoP deficit.
b) Use the case of China’s BoP surplus in the early 2000s and Greece’s BoP deficit during the European debt crisis to analyze the macroeconomic outcomes of such imbalances.

A

a) A BoP surplus means inflows exceed outflows, leading to reserve accumulation, while a deficit indicates reliance on foreign borrowing.
b) China’s surplus supported economic growth through reserves and exports. Greece’s deficit required external funding, leading to austerity measures and economic contraction during the crisis.

46
Q

During the 1997 Asian Financial Crisis, several countries experienced significant outflows of foreign portfolio investment.
a) How would this capital outflow be recorded in the balance of payments?
b) Analyze how this contributed to currency devaluations and broader economic instability in affected countries such as Thailand or Indonesia.

A

a) Capital outflows are recorded as a reduction in the capital account balance.
b) These outflows reduced foreign reserves, forcing countries to devalue currencies. Currency devaluations led to inflation, reduced purchasing power, and economic contraction, deepening the crisis.

47
Q

Explain why there is no BoP deficit in a floating exchange rate regime, and contrast this with the situation in a fixed exchange rate regime.

A

In a floating exchange rate regime:

The central bank does not intervene, so ORA = 0 (no changes in official reserves).
OSB = 0 because no central bank action adjusts flows, and the market balances via exchange rate changes.
Therefore, there is no BoP deficit as imbalances adjust through currency appreciation or depreciation.

In a fixed exchange rate regime:

The central bank intervenes to maintain the exchange rate, leading to ORA ≠ 0.
If OSB < 0, the central bank uses its reserves to cover the deficit, allowing a BoP deficit to exist.

48
Q

How does the central bank’s role in the forex market differ between fixed and floating exchange rate regimes?

A

In a fixed exchange rate regime, the central bank actively intervenes by buying or selling foreign reserves to maintain the exchange rate. For example, China historically bought USD to keep the yuan undervalued.

In a floating exchange rate regime, such as the US dollar system, the central bank does not intervene, and exchange rates are determined by market forces of supply and demand.

49
Q

A Dutch importer pays €1 to a US exporter. If the US exporter decides to hold euros rather than convert them, what impact will this have on the forex market?

A

If the US exporter holds euros:

The euro supply in the forex market does not increase because the currency is not converted into USD.
This action prevents additional depreciation pressure on the euro.

The BoP still records the transaction as:

Current account: Debit of −€1 (Dutch import).
Financial account: Credit of +€1 (export of currency).

50
Q

What happens to the supply and demand for a currency in the forex market if a country has a current account deficit?

A

A current account deficit means a country imports more than it exports:

Demand for foreign currency increases (to pay for imports).
Supply of the domestic currency increases (to purchase foreign currency).

This imbalance puts downward pressure on the domestic currency, leading to potential depreciation in a floating exchange rate system.

51
Q

Explain how BoP adjustments differ between a country with a large current account surplus and one with a deficit under a floating exchange rate system.

A

A current account surplus (e.g., Japan): Foreign demand for the domestic currency increases, appreciating the currency and reducing competitiveness of exports.

A current account deficit (e.g., the US): Supply of the domestic currency in the forex market increases, depreciating the currency and making exports more competitive.

Both surpluses and deficits self-adjust over time through exchange rate changes.

52
Q

What role does the financial account play in balancing the current account?

A

The financial account offsets the current account imbalance:

If a country runs a current account deficit, it attracts foreign investments or borrows, creating a financial account surplus.

Example:

The US often runs a current account deficit, financed by foreign purchases of US assets (e.g., Treasury bonds).
This results in a financial account surplus, balancing the BoP

53
Q

Why might a country with a persistent BoP deficit deplete its foreign reserves in a fixed exchange rate regime?

A

In a fixed exchange rate regime, the central bank uses foreign reserves to maintain the peg:

Persistent BoP deficits mean the country imports more than it exports.
To support the domestic currency, the central bank sells foreign reserves to meet forex demand.
Without corrective policies, reserves may deplete, risking a currency crisis (e.g., Mexico in 1994).

54
Q

Suppose the euro depreciates significantly due to BoP transactions. What impact might this have on European exports and imports?

A

Effects of euro depreciation:

Exports become cheaper for foreign buyers, increasing demand for European goods.

Imports become more expensive for Europeans, reducing import volumes.

Overall, the current account deficit may shrink, illustrating the self-correcting mechanism of a floating exchange rate system.

55
Q

How does a BoP surplus affect a country’s foreign reserves under a fixed exchange rate regime?

A

A BoP surplus occurs when exports and financial inflows exceed imports and outflows:

The central bank buys foreign currency to prevent the domestic currency from appreciating.
This leads to an accumulation of foreign reserves.

Example: China’s persistent trade surplus with the US led to massive foreign reserve accumulation.

56
Q

In a floating exchange rate regime, how does the balance of payments (BoP) adjust after a currency depreciation, and what role does the central bank play in this process?

A

In a floating exchange rate regime:

Depreciation pressure materializes as the exchange rate fluctuates based on market supply and demand.

The BoP adjusts automatically with each transaction, maintaining equilibrium (ORA = 0, OSB = 0).

The central bank does not intervene, allowing real-time adjustments in the forex market.

Example: A weaker euro increases exports and reduces imports, helping correct a BoP deficit.

57
Q

Explain why depreciation might not be a “painless” solution for correcting a BoP deficit.

A

Depreciation challenges:

Trade effects: Exports become cheaper, and imports more expensive, which can strain domestic consumers.

Capital flows: Foreign investors may be deterred, fearing further depreciation and reduced returns.

External debt: For countries with foreign currency-denominated debt, repayment costs increase.

Example: Argentina’s peso depreciation in 2001 worsened its debt crisis as dollar-denominated loans became unmanageable.

58
Q

What happens to the BoP entries when the central bank intervenes in a fixed exchange rate regime to prevent depreciation?

A

In a fixed exchange rate regime:

The central bank sells foreign reserves to buy domestic currency.

BoP records the intervention as:
Official Reserve Account (ORA): +€1 (use of reserves).
Capital Account (K): −€1 (capital inflow recorded to balance)

59
Q

If a country under a fixed exchange rate regime raises interest rates to counteract depreciation pressure, how does this affect the BoP?

A

Higher interest rates attract foreign investment, creating a capital inflow:

Capital account (K) sees an inflow due to increased demand for domestic assets.

Official reserves (ORA) are unaffected as the inflows are market-driven.

Example: In the 1990s, the UK used high interest rates to defend the pound before exiting the ERM.

60
Q

Describe the impact of currency depreciation on a country’s external debt if the debt is denominated in foreign currency.

A

Currency depreciation increases the local currency cost of servicing foreign currency debt:

Example: If the euro depreciates against the dollar, repaying USD-denominated loans becomes more expensive in euros.

This can strain government budgets and reduce financial stability, especially in highly indebted countries.

61
Q

Compare the role of supply and demand in determining exchange rates under floating and fixed regimes.

A

Floating regime: Exchange rates are fully market-driven by supply and demand.

Example: A rise in demand for euros due to increased EU exports appreciates the euro.

Fixed regime: The central bank intervenes to control rates, using reserves or monetary policy to counteract market forces.

62
Q

Explain how a fixed exchange rate regime can lead to reserve depletion during sustained depreciation pressure.

A

The central bank sells foreign reserves to buy domestic currency, defending the peg.

If pressure persists (e.g., large capital outflows or trade deficits), reserves can deplete entirely, risking a currency crisis.

Example: Thailand’s reserve depletion during the 1997 Asian Financial Crisis forced it to abandon its currency peg.

63
Q

Why might investors avoid a country experiencing currency depreciation under a floating regime?

A

Investors fear:

Further depreciation, reducing the value of their returns in home currency.

Economic instability as depreciation can signal fiscal or trade issues.

Example: After the Turkish lira depreciated in 2018, foreign investment sharply declined due to perceived risk.

64
Q

Explain how BoP transactions in the forex market influence currency depreciation, using the euro as an example.

A

When euros are sold to acquire another currency:

Supply of euros increases in the forex market.
Excess supply relative to demand puts downward pressure on the euro, causing depreciation.

Example: A large trade deficit where the EU imports significantly more than it exports can lead to sustained euro depreciation.

65
Q

What are the potential consequences for a central bank if it depletes its foreign reserves while defending a fixed exchange rate?

A

Depleting reserves can lead to:

Loss of ability to defend the exchange rate, resulting in forced devaluation.

Loss of investor confidence, leading to capital outflows.

Currency crises, as experienced by Thailand during the 1997 Asian Financial Crisis.

Example: Thailand’s depletion of reserves forced it to abandon its fixed peg, triggering a broader financial collapse.

66
Q

How do high interest rates, used to defend a fixed exchange rate, impact an economy in the long term?

A

High interest rates can:

Discourage domestic borrowing and investment, slowing economic growth.

Increase government debt servicing costs if public debt is substantial.

Reduce consumer spending, exacerbating economic contraction.

Example: The UK’s high interest rates in the 1990s ERM crisis hurt domestic businesses and led to public backlash before the pound exited the system.

67
Q

Describe a scenario where a central bank’s inability to raise interest rates or sell reserves leads to a currency crisis. How can this be avoided?

A

Scenario:

The central bank faces reserve depletion and cannot raise rates due to recession risks.

Peg collapses, leading to uncontrolled devaluation.

Avoidance strategies:

Maintain adequate reserve levels.
Use capital controls to stem outflows.

Transition to a floating exchange rate if maintaining the peg becomes unsustainable.

Example: Argentina’s inability to maintain its currency peg in 2001 led to a severe economic and social crisis.

68
Q

What trade-offs does a central bank face when choosing between selling reserves and raising interest rates to defend a fixed exchange rate?

A

Selling reserves:

Pros: Immediate currency support without directly affecting the domestic economy.

Cons: Limited by reserve holdings; depletion risks a currency crisis.
Raising interest rates:

Pros: Attracts foreign capital, boosting reserves indirectly.

Cons: Reduces domestic investment and growth, potentially leading to a recession.

Example: During the 1997 Asian Financial Crisis, several countries faced the dual challenge of depleted reserves and high rates, causing widespread economic damage.

69
Q

Explain why central bank interventions in fixed exchange rate regimes are not “painless” and discuss the broader implications for economic policy.

A

Interventions are costly because:

Selling reserves is unsustainable if pressures persist, risking reserve depletion and forced devaluation.

High interest rates harm domestic economic growth and increase debt burdens.

Broader implications:

Effective BoP management is critical to avoid crises.

Policymakers must weigh short-term stability against long-term economic health.

70
Q

Explain the relationship between a country’s current account (CA) deficit and its Net International Investment Position (NIIP). Why does a persistent CA deficit often lead to a worsening NIIP?

A

A current account (CA) deficit implies that a country spends more on imports and foreign transfers than it earns from exports and foreign income. To balance the deficit:

  • The country must attract foreign capital, leading to a positive capital account (K > 0).
  • This results in borrowing from abroad or selling domestic assets to foreign investors, increasing Net Foreign Debt (NFD).

Over time, persistent CA deficits worsen NIIP as foreign liabilities exceed foreign assets.

Example: The United States has sustained CA deficits for decades, financed by foreign investors purchasing U.S. assets, making the U.S. the world’s largest debtor nation with a negative NIIP.

71
Q

If the balance of payments (BoP) equals zero in a floating exchange rate regime, why does this not necessarily imply that the current account (CA) is balanced?

A

In a floating exchange rate regime, BoP = 0 because any imbalance in the current account (CA) is offset by the capital account (K). A CA deficit (CA < 0) is balanced by foreign capital inflows (K > 0).

Example:
The U.S. consistently has a CA deficit, financed by foreign investors buying U.S. assets (K > 0). While BoP = 0, the sustained CA deficit worsens the U.S.’s NIIP as foreign ownership of U.S. assets increases.

72
Q

Discuss how valuation effects can influence a country’s NIIP even when the current account (CA) is balanced. Use the impact of exchange rate changes

A

When CA = 0, NIIP can still change due to valuation effects, which reflect changes in the value of existing foreign assets and liabilities.

Example (Exchange Rate Changes):

If the euro appreciates against the dollar, the dollar value of U.S. assets in the Eurozone increases.

Suppose the U.S. owns €100 million in Eurozone stocks; an appreciation of the euro raises the dollar value of these assets, improving U.S. NIIP despite no new asset purchases.

73
Q

Why is a BoP = 0 not necessarily an indicator of economic health?

A

A BoP = 0 simply reflects a balance between the current account (CA) and capital account (K). If BoP = 0 due to persistent CA deficits:

  1. Foreign debt increases as the country borrows or sells domestic assets.
  2. NIIP worsens over time, making the country more dependent on foreign capital.

Example: The U.S. has had a BoP = 0 for years, but sustained CA deficits have made it the largest debtor nation, with a negative NIIP that reflects long-term financial vulnerability.

74
Q

Analyze how a depreciation of the domestic currency can stabilize or improve NIIP, even during a period of current account deficits.

A

Depreciation can stabilize or improve NIIP through valuation effects:

  1. It increases the local currency value of foreign assets held by domestic residents.
  2. Makes existing liabilities relatively cheaper in foreign currency terms.

Example: From 2001-2007, the U.S. ran ongoing CA deficits. However, the U.S. dollar depreciated against other currencies, increasing the dollar value of its foreign-held assets. This offset the worsening effect of the CA deficit, keeping NIIP relatively stable.

75
Q

Explain the export price effect of currency depreciation on a country’s current account.

A

When a currency depreciates (e.g., euros), foreign buyers find goods cheaper in their own currency (e.g., dollars). This increases demand for exports, enabling exporters to raise prices in the domestic currency to capitalize on higher demand. This leads to increased export revenue and can improve the current account (CA).

Example: After the euro depreciated in 2014, European car manufacturers like Volkswagen saw increased sales in the U.S., as their cars became cheaper for American consumers. This boosted Germany’s export revenue and improved its CA balance.

76
Q

How does the export volume effect contribute to changes in the current account following currency depreciation?

A

Currency depreciation makes a country’s goods cheaper in foreign currencies, increasing their competitiveness. Foreign buyers purchase more, leading to higher export volumes and an improvement in the current account.

Example: After the Japanese yen depreciated in 2013, exports of Japanese electronics and vehicles surged due to their reduced prices in foreign markets, positively affecting Japan’s CA.

77
Q

Discuss how the import price effect of depreciation can negatively impact the current account.

A

Depreciation raises the cost of imported goods in the home currency. The country spends more on the same quantity of imports, worsening the CA deficit if import volumes remain steady.

Example: Following the depreciation of the British pound after Brexit in 2016, the U.K. saw rising costs for imported goods like oil and food, increasing its import bill and negatively impacting the CA.

78
Q

Describe the import volume effect of currency depreciation and its implications for the current account.

A

Depreciation increases the price of imports in the home currency, leading domestic consumers to reduce their reliance on imports and switch to locally produced goods. This reduces import volumes and improves the CA.

Example: After the Argentine peso depreciated in 2018, imports of luxury goods dropped significantly as consumers turned to local alternatives, helping stabilize Argentina’s CA.

79
Q

Why is the net effect of currency depreciation on the current account ambiguous?

A

Depreciation affects exports and imports through four main channels (price and volume effects for both). The net effect depends on the elasticities of demand for exports and imports:

High elasticity: Significant increases in export volume and reductions in import volume improve the CA.

Low elasticity: Export volumes may not rise enough, and import costs could dominate, worsening the CA.

Example: The 2016 pound depreciation initially hurt the U.K.’s CA due to high import costs but later improved due to increased exports of British goods.

80
Q

Explain how high price elasticity of exports and imports influences the current account response to currency depreciation.

A

High elasticity means that buyers significantly adjust their behavior in response to price changes:

Export volumes increase sharply due to lower prices in foreign currencies, boosting export revenue.

Import volumes decrease significantly as higher prices discourage domestic consumers, reducing import costs.
This combination leads to a strong improvement in the CA.

Example: South Korea’s CA benefited after the won depreciated in the early 2000s, as both export volumes surged and import demand fell sharply.

81
Q

Analyze the impact of low price elasticity of imports and exports on the effectiveness of currency depreciation in improving the current account.

A

With low elasticity:

Export volumes may not increase significantly, limiting revenue growth despite lower prices.

Import volumes may remain unchanged, but higher prices lead to increased costs, worsening the CA.

Example: In 1997, Thailand’s currency depreciation during the Asian Financial Crisis failed to improve its CA quickly due to inelastic demand for key imports like oil.

82
Q

How might a country with high external debt in foreign currency experience additional challenges from currency depreciation?

A

Currency depreciation makes it more expensive to repay foreign-currency-denominated debt in the home currency. This increases financial strain and can offset any benefits from improved export competitiveness.

Example: Argentina faced increased debt servicing costs in 2018 after the peso depreciated, as much of its external debt was denominated in U.S. dollars.

83
Q

Compare and contrast the export price effect and the export volume effect of currency depreciation. How do they collectively impact the current account?

A

Export price effect: Exporters raise prices in the home currency due to increased foreign demand, boosting revenue.

Export volume effect: Lower foreign-currency prices increase export volumes.

Together, these effects improve the CA if demand for exports is price-elastic.

Example: Post-2014 euro depreciation improved the Eurozone’s CA through both higher-priced exports and increased export volumes in industries like automotive and luxury goods.

84
Q

Using the Marshall-Lerner condition, explain under what circumstances currency depreciation will improve the current account.

A

The Marshall-Lerner condition states that depreciation improves the CA if the sum of the absolute price elasticities of demand for exports and imports exceeds 1.

Example:

Elastic markets (e.g., electronics): Depreciation improves the CA, as export demand rises significantly and imports drop sharply.

Inelastic markets (e.g., oil): Depreciation may worsen the CA, as import volumes remain steady while costs rise.

Japan’s yen depreciation in 2013 improved its CA due to elastic demand for its automotive exports.

85
Q

Explain the concept of a horizontal supply curve in the context of exports and imports. Why does this assumption make demand the sole determinant of export and import volumes?

A

A horizontal supply curve implies perfectly elastic supply, where the quantity supplied can increase or decrease without any change in price. In this scenario:

Exports (X): Export prices (Px) are fixed in the home currency. Thus, only changes in foreign demand influence export volumes.

Imports (M): Import prices (Pm) are fixed in the foreign supplier’s currency. Changes in home demand determine import volumes.

Example: A German car exported to the U.S. is always priced at €30,000 in euros, regardless of how many units the U.S. imports. The U.S. demand alone determines the volume of exports.

86
Q

How does the price elasticity of export demand (ηx) influence export volume under the horizontal supply curve assumption?

A

The price elasticity of export demand (ηx) measures how sensitive export volume (x) is to changes in the foreign price of exports (Px*). Under the horizontal supply curve:

A higher ηx means small changes in Px* cause large changes in x.

A lower ηx means export volumes are less responsive to price changes.

Example: If ηx = 2 for European wine exports, a 5% decrease in the price of wine in dollars (Px*) would lead to a 10% increase in U.S. demand for European wine.

87
Q

Why is the home currency price of exports (Px) constant under the horizontal supply curve assumption?

A

Under this assumption, exporters supply as much as demanded at a fixed price in the home currency. Export prices do not change, even if demand increases or decreases.

Implications:

Export revenue depends only on export volume (not price changes).

Exporters face greater risk if foreign demand collapses because they cannot raise prices to compensate.

Example: A Brazilian coffee exporter sells coffee at a fixed price of BRL 100 per unit, regardless of demand fluctuations in international markets.

88
Q

How does the horizontal supply curve assumption affect the relationship between import volume (M) and its price (Pm)?

A

With horizontal supply curves:

The price of imports (Pm) is fixed in the supplier’s currency.

Import volumes (M) depend only on the price elasticity of import demand (ηm) and changes in domestic demand.

Example: If ηm for smartphones is -1.5, a 10% increase in the price of imported smartphones in the home currency leads to a 15% decrease in import volume.

89
Q

What is the significance of ηx and ηm in determining the responsiveness of trade volumes to price changes under fixed supply prices?

A

ηx (price elasticity of export demand): Indicates how sensitive export volumes are to changes in foreign prices. Higher ηx implies exports are highly responsive to price changes, benefiting from lower foreign prices.

ηm (price elasticity of import demand): Indicates how sensitive import volumes are to changes in home prices. Higher ηm suggests consumers will drastically reduce imports when prices rise.

Example: A country with high ηx and ηm will experience significant trade volume changes when exchange rates fluctuate.

90
Q

If the price of imports (Pm) rises due to currency depreciation, how does the price elasticity of import demand (ηm) determine the current account’s response?

A

When Pm rises due to depreciation:

High ηm: Import volumes drop significantly, reducing import expenditures and improving the current account.

Low ηm: Import volumes remain relatively constant, worsening the current account due to higher import costs.

Example: After the Indian rupee depreciated in 2018, the price of imported oil rose. Since oil has low ηm (inelastic demand), import volumes did not drop significantly, worsening India’s trade deficit

91
Q

Under the horizontal supply curve assumption, what would happen to a country’s export volumes if the foreign currency appreciates against the home currency?

A

If the foreign currency appreciates, the price of exports in foreign currency (Px*) decreases:

High ηx: Export volumes increase significantly, boosting trade revenue.

Low ηx: Export volumes change marginally, limiting revenue growth.

Example: The yen depreciation in 2013 caused Japanese electronics to become cheaper in foreign markets, leading to a sharp increase in exports due to high ηx in the electronics sector.

92
Q

How does the horizontal supply curve assumption impact policy measures aimed at improving trade balances?

A

Under horizontal supply:

Prices remain constant, so policymakers must focus on factors affecting demand (e.g., exchange rate adjustments or trade agreements).

Elasticities (ηx and ηm) determine the effectiveness of such measures.

Example: A depreciation of the British pound after Brexit improved export demand for U.K. goods (high ηx) but had a limited impact on reducing oil imports (low ηm).

93
Q

Critically evaluate the assumption of horizontal supply curves in the context of global trade. Why might this assumption fail in the real world?

A

Horizontal supply curves assume perfect elasticity, which is rarely true due to:

Supply constraints (e.g., production capacity limits).

Price adjustments by producers in response to demand changes.

Market imperfections like tariffs or trade barriers.

Example: In 2021, supply chain disruptions caused semiconductor prices to rise significantly, contradicting the horizontal supply assumption and affecting global trade volumes.

94
Q

Explain the relationship between the exchange rate (S), currency depreciation, and the Marshall-Lerner condition in determining the impact on the current account (CA).

A

Currency depreciation (increase in S) makes exports cheaper and imports more expensive, affecting the CA via the Marshall-Lerner condition:

Marshall-Lerner: If ηx + ηm > 1, the volume effect dominates, and CA improves.

Numerical Example: Suppose ηx = 0.8 and ηm = 0.4. Then ηx + ηm = 1.2 > 1 → CA improves as depreciation increases export demand and reduces import demand.

95
Q

How does the price effect of currency depreciation affect the current account under the simplifying assumption that export prices (Px) do not change?

A

Price Effect:
Export prices (Px): Constant → no impact on CA.

Import prices (Pm): Rise with depreciation → negative impact on CA.

Net Price Effect: 0 - 1 = -1 → Negative overall impact.
Thus, without a strong volume effect, the CA worsens due to increased import costs.

96
Q

If ηx + ηm < 1, why does currency depreciation fail to improve the CA?

A

When ηx + ηm < 1, the price effect dominates because the change in volumes (exports and imports) is not significant enough to offset the increased cost of imports.

Example: In the 1980s, the U.S. experienced persistent trade deficits despite dollar depreciation because import volumes remained high (low ηm) while export growth was sluggish (low ηx).

97
Q

Compare the short-run and long-run impacts of currency depreciation on the CA. Why do adjustments differ over time?

A

Short-Run:

Limited change in export/import volumes due to contracts, habits, and production constraints.

Import costs rise immediately, worsening the CA.

Long-Run:

Export volumes rise, and import volumes fall as buyers adjust to new prices.

Positive volume effect improves the CA.

Example: The J-Curve effect describes this pattern: initial CA deterioration followed by improvement over time

98
Q

A country has ηx = 0.6 and ηm = 0.8. Will a 10% currency depreciation improve its CA? Justify your answer using the Marshall-Lerner condition.

A

Calculation: ηx + ηm = 0.6 + 0.8 = 1.4 > 1.

Since ηx + ηm > 1, the volume effect dominates the price effect, and CA will improve with a 10% depreciation as exports rise and imports fall.

99
Q

Why might the U.S. struggle to improve its CA deficit through currency depreciation despite ηx + ηm > 1?

A

High absolute import volumes mean that even small price increases significantly raise total import expenditures.

Example: If the U.S. spends $1 trillion annually on imports, a 10% price rise adds $100 billion to costs, potentially offsetting gains from higher exports.

100
Q

Explain why China, despite ηx + ηm < 1, can still improve its CA surplus following currency depreciation.

A

In a surplus, the negative price effect is minimal because imports are low relative to exports.

Depreciation makes exports even more attractive, boosting export volumes and sustaining the surplus.

Example: China’s export-driven economy benefited from a weaker yuan in the early 2000s, maintaining large trade surpluses.

101
Q

Suppose a country with a CA deficit experiences a depreciation of its currency. How does the elasticity approach suggest policymakers should respond?

A

The elasticity approach indicates that policymakers should focus on increasing ηx and ηm to ensure ηx + ηm > 1.

Measures include improving export competitiveness and reducing dependency on inelastic imports.

Example: South Korea diversified exports and reduced energy import reliance, enabling better CA adjustment post-1997 currency crisis.

102
Q

Using the formula dCA/dS = ηx + ηm – 1, explain the role of elasticity magnitude in determining CA outcomes for a 5% depreciation. Provide calculations.

A

Example: Assume ηx = 0.5, ηm = 0.6.
dCA/dS = 0.5 + 0.6 – 1 = 0.1 > 0.

A 5% depreciation improves the CA slightly (5% × 0.1 = 0.5% improvement).

If ηx = 0.3 and ηm = 0.4, then dCA/dS = -0.3 → CA worsens.

103
Q

How does the J-Curve explain the time-lagged improvement in the CA following currency depreciation?

A

Initial Decline: Import costs rise before export and import volumes adjust.

Delayed Improvement: Export volumes rise, and import volumes fall as contracts expire and buyers adapt.

Example: After the 1992 sterling devaluation, the U.K. initially saw a worsening trade deficit, followed by gradual improvement as exports surged.
