Question 1

What is the difference between fixed and managed float exchange rates in the context of the IB DP Economics syllabus?

Accepted Answer

In the IB DP Economics syllabus, a fixed exchange rate is one where a country's currency value is tied to another major currency or a basket of currencies. The government or central bank intervenes to maintain the currency's value within a narrow band. In contrast, a managed float exchange rate, also known as a dirty float, allows the currency to fluctuate in the open market, but the central bank may intervene occasionally to stabilize or influence the currency's value.

Question 2

How do fixed exchange rates impact a country's economy?

Accepted Answer

Fixed exchange rates can provide stability in international prices, which can encourage trade and investment. However, maintaining a fixed rate requires large reserves of foreign currency and can limit a country's ability to respond to economic shocks. It may also lead to trade imbalances if the fixed rate does not reflect the true market value of the currency.

Question 3

What are the advantages of a managed float exchange rate system?

Accepted Answer

A managed float exchange rate system offers flexibility, allowing a currency to adjust to economic conditions while still providing some level of stability through central bank interventions. This can help a country respond to economic shocks and maintain competitiveness. It also reduces the need for large reserves of foreign currency compared to a fixed exchange rate system.

Question 4

Why might a country choose a fixed exchange rate over a managed float system?

Accepted Answer

A country might choose a fixed exchange rate to provide greater certainty in international trade and investment, as it reduces the risk of currency fluctuations. This can be particularly beneficial for countries with economies heavily reliant on exports. Additionally, a fixed rate can help control inflation by tying the currency to a stable foreign currency.

Question 5

What role do central banks play in a managed float exchange rate system?

Accepted Answer

In a managed float exchange rate system, central banks play a crucial role by intervening in the foreign exchange market to stabilize or influence the currency's value. This can involve buying or selling foreign currencies to adjust the exchange rate, implementing monetary policies, or using interest rates to influence currency demand. These actions help maintain economic stability and prevent excessive volatility in the currency market.
