You are expected to explain/analyze (AO2) methods to correct a persistent current account deficit, and evaluate/examine (AO3) their effectiveness (HL)
There are quite a few ways governments can correct persistent current account deficits. This includes:
Expenditure switching: The government may decide to encourage consumers and businesses to buy domestic products over imports. This means they still spend money, but the deficit will be smaller.
This can for example be done by imposing tariffs, quotas, or subsidies, as well as devaluing the currency (makes foreign goods look more expensive)
Expenditure reducing: The government may decide to impose measures meant to cut expenditure as a whole.
Supply-side policies: The government may decide to improve the economy's export competitiveness instead, by investing in or deregulating industries.
This can for example be done by improving infrastructure, investing in education, and provide tax breaks for startups.
Expenditure switching:
Many consumers may have preferences regardless of price, and may still choose to buy imported goods
The imposition of trade barriers such as tariffs and quotas may cause retaliations in other countries, decreasing exports
Devaluing the currency will mean important imported goods (such as oil and electricity) will be more expensive, causing inflation
Expenditure reducing:
Expenditure reducing policies basically aim to hurt the economy to decrease demand. This will decrease economic well-being and growth
Supply-side policies:
It takes a very long time for its effects to show, and will not be very useful in the short run
