Question 1 of 7
1. Question
Consider the following statements:
1. Currency appreciation
2. Decline in manufacturing
3. Increased export competitiveness
Dutch Disease is associated with which of the following?
Correct
Answer: A
Explanation:
-
- Dutch Disease begins with a sudden surge in foreign exchange inflows due to a natural resource boom (oil, gas, minerals, etc.).
- These inflows increase demand for the domestic currency, causing real exchange rate appreciation.
- Appreciation means domestic goods become more expensive for foreign buyers, which is a core feature of Dutch Disease.
- Manufacturing is a tradable and export-oriented sector.
- Currency appreciation reduces price competitiveness of manufactured exports in global markets.
- Simultaneously, labour and capital shift towards the booming resource sector and non-tradable sectors (construction, services).
- This leads to de-industrialisation, a hallmark of Dutch Disease.
- Export competitiveness declines, not increases, because:
- Appreciated currency raises export prices.
- Domestic producers lose market share internationally.
