What are the main methods to correct a persistent current account deficit in the context of the IB DP Economics curriculum?

In the IB DP Economics curriculum, the main methods to correct a persistent current account deficit include expenditure-reducing policies, expenditure-switching policies, and supply-side policies. Expenditure-reducing policies aim to decrease overall demand in the economy, often through fiscal or monetary measures. Expenditure-switching policies focus on altering the relative prices of exports and imports, typically through exchange rate adjustments or trade policies. Supply-side policies aim to enhance the competitiveness of domestic industries by improving productivity and efficiency.

How do expenditure-reducing policies help in correcting a current account deficit?

Expenditure-reducing policies help correct a current account deficit by reducing the overall level of demand in the economy. This can be achieved through contractionary fiscal policies, such as increasing taxes or reducing government spending, and contractionary monetary policies, like raising interest rates. By decreasing domestic consumption and investment, these policies can lead to a reduction in imports, thereby improving the current account balance.

Can exchange rate adjustments effectively address a current account deficit?

Yes, exchange rate adjustments can effectively address a current account deficit. By devaluing the national currency, a country can make its exports cheaper and imports more expensive. This can lead to an increase in export volumes and a decrease in import volumes, thereby improving the current account balance. However, the effectiveness of this method depends on the price elasticity of demand for exports and imports, as well as other factors such as global economic conditions and trade agreements.

What role do supply-side policies play in correcting a current account deficit?

Supply-side policies play a crucial role in correcting a current account deficit by enhancing the competitiveness of a country's industries. These policies focus on improving productivity, innovation, and efficiency within the economy. Measures may include investing in education and training, reducing regulatory burdens, and encouraging research and development. By boosting the competitiveness of domestic goods and services, supply-side policies can increase exports and reduce reliance on imports, thus improving the current account balance.

What are the potential drawbacks of using protectionist measures to correct a current account deficit?

While protectionist measures, such as tariffs and quotas, can temporarily reduce a current account deficit by limiting imports, they have several potential drawbacks. These measures can lead to trade wars, increase the cost of goods for consumers, and reduce the overall efficiency of the global economy. Additionally, protectionism can provoke retaliation from trading partners and may violate international trade agreements. In the long term, it can also stifle domestic innovation and competitiveness, making it a less sustainable solution for correcting a current account deficit.

Why is "Recommending only ONE tool." a common mistake in Methods to correct a persistent current account deficit?

Why it happens: Simplification. How to avoid it: Each has weaknesses. Realistic correction uses combination.

Methods to Correct a Persistent Current Account Deficit — IB Economics SL: expenditure switching, expenditure reducing, supply-side

Unit 4.6 of the 2022+ syllabus. Policy options to address persistent deficits — expenditure switching (depreciation, protection), expenditure reducing (austerity, tighter monetary), and supply-side (productivity, competitiveness).

What you’ll learn

Mapped to the IB DP Economics SL subject guide (2022 onwards (first assessment May 2024)).

4.6.7 — Distinguish expenditure switching, reducing, and supply-side.
4.6.8 — Discuss trade-offs of each policy.

Three policy approaches

Switch, reduce, or boost competitiveness.

Three policy categories to correct a current account deficit:

1. Expenditure switching. Shift demand from imports to domestic goods.

Policy	How it works
Devaluation / depreciation	Imports more expensive; exports cheaper for foreigners
Tariffs / quotas	Raise import prices; switch demand to domestic
Subsidies	Make domestic goods cheaper than imports
Internal devaluation	Cut domestic wages and prices (for eurozone members without own currency)

Trade-offs:

Depreciation raises inflation.
Protection invites retaliation, breaches WTO rules.
Internal devaluation is recessionary (Greece 2010-12).

2. Expenditure reducing. Cut overall spending → less imported demand.

Policy	How it works
Contractionary fiscal policy	Higher taxes, lower G → AD down → imports fall
Contractionary monetary policy	Higher rates → less borrowing/spending → imports fall

Trade-offs:

Recession, unemployment.
Hurts growth.
Politically difficult.

3. Supply-side policies. Improve competitiveness — make exports more attractive.

Policy	How it works
Education and training	Higher labour productivity → cheaper unit labour costs
R&D subsidies	Innovation → better products → exports rise
Infrastructure investment	Lower business costs → exports rise
Labour market reform	Flexible wages → unit costs adjust
Industrial policy	Strategic support for export industries

Trade-offs:

LONG lags.
Fiscal cost.
Risk of picking wrong winners.

Combining policies. Realistic correction often needs ALL THREE:

Short-run: expenditure reducing or switching to stabilise immediately.
Medium-run: supply-side to build sustainable competitiveness.

Real-world example. UK 2008-2016 had sterling depreciation (switching), some fiscal tightening (reducing), and weak productivity growth — current account deficit narrowed only modestly.

IMF prescriptions for crisis countries often involve fiscal austerity, currency depreciation (if not fixed), and structural reforms — controversial because of social and political costs.

Switching: depreciation, tariffs, subsidies, internal devaluation.
Reducing: contractionary fiscal/monetary.
Supply-side: education, R&D, infrastructure.
Combination often needed.

Step-by-step solutions to past-paper-style questions on methods to correct a persistent current account deficit, written exactly the way a tutor would explain them at the board.

1Compare correction policies
Stretch• policy
Question
Discuss the trade-offs of using depreciation versus austerity to correct a persistent CA deficit. (5 marks)
Step-by-step solution
1. Step 1
  Depreciation (switching): exports rise, imports fall. Improves CA if Marshall-Lerner holds.
2. Step 2
  But: imported inflation, J-curve short-run worsening, risks retaliation.
3. Step 3
  Austerity (reducing): cuts overall demand → imports fall, CA improves.
4. Step 4
  But: recession, unemployment, political pain.
5. Step 5
  Combination often used; supply-side reforms add long-run sustainability.
Answer
Depreciation faster but inflation cost. Austerity recessionary. Combination + supply-side optimal.
2Internal devaluation
Stretch• internal devaluation
Question
Explain why Greece had to use 'internal devaluation' after 2010, and what this involved. (3 marks)
Step-by-step solution
1. Step 1
  Greece in eurozone — couldn't depreciate its own currency (no euro depreciation against itself).
2. Step 2
  Internal devaluation = cut domestic wages and prices to restore competitiveness.
3. Step 3
  Mechanism: austerity, lower wages, deregulation; deeply recessionary (25% unemployment). Eventually some CA improvement, but social cost severe.
Answer
Eurozone members can't depreciate currency; must cut wages and prices internally — deeply painful.
